    2009-05-01

    Capturing the interest of our students is imperative to expand the conduit of future Earth scientists in the United States. According to the Rising Above the Gathering Storm report (2005), we must increase America's talent pool by improving K-12 mathematics and science education. Geoscience education is uniquely suited to accomplish this goal, as we have become acutely aware of our sensitivity to the destructive forces of nature. The educational community must take advantage of this heightened awareness to educate our students and ensure the next generation rebuilds the scientific and technological base on which our society rests. In response to these concerns, the National Science Foundation advocates initiatives in Geoscience Education such as IDGE (Integrated Design for Geoscience Education), which is an inquiry-based geoscience program for Upward Bound (UB) students at Marshall University in Huntington, West Virginia. The UB program targets low-income under-represented students for a summer academic-enrichment program. IDGE builds on the mission of UB by encouraging underprivileged students to investigate science and scientific careers. During the two year project, high school students participated in an Environmental Inquiry course utilizing GLOBE program materials and on-line learning modules developed by geoscience specialists in land cover, soils, hydrology, phenology, and meteorology. Students continued to an advanced course which required IDGE students to collaborate with GLOBE students from Costa Rica. The culmination of this project was an educational expedition in Costa Rica to complete ecological field studies, providing first-hand knowledge of the international responsibility we have as scientists and citizens of our planet. IDGE was designed to continuously serve educators and students. By coordinating initiatives with GLOBE headquarters and the GLOBE country community, IDGE's efforts have yielded multiple ways in which to optimize positive

    Science.gov (United States)

    Gillis-Davis, J. J.; Sherman, S. B.; Gillis-Davis, L. C.; Svelling, K. L.

    2009-12-01

    We developed a two-phased curricula aimed at high school students in Hawaii’s Upward Bound (UB) programs. The course, called “Tour Through the Solar System”, was tested in the summer 2008-2009 programs of two of the four Hawaii UB programs. Authorized by Congress in 1965, UB is a federal program funded by the U.S. Department of Education to serve students underrepresented in higher education. Students enrolled in UB are predominantly low income, or from families in which neither parent holds a bachelor’s degree. UB programs make a measurable improvement in retaining high school students in the education pipeline in part by using innovative educational and outreach programs to spark students’ interest in learning while building academic self-confidence. Curricula developed for UB are sustainable because there are 964 programs in the United States, and U territories. Education and outreach products can be presented at regional and national meetings, which directors of the UB programs attend. Broad regulations and varied instruction formats allow curriculum developers a flexible and creative framework for developing classes. For instance, regulations stipulate that programs must provide participants with academic instruction in mathematics, laboratory sciences, composition, literature, and foreign languages in preparation for college entrance. UB meets these guidelines through school-year academic activities and a six-week summer school program. In designing our curricula the primary goals were to help students learn how to learn and encourage them to develop an interest in the fields of science, technology, engineering and math using NASA planetary data sets in a Problem-Based Learning (PBL) environment. Our focus on planetary science stems from our familiarity with the data sets, our view that NASA data sets are a naturally inspirational tool to engage high school students, and its cross-disciplinary character: encompassing geology, chemistry, astronomy

    2015-12-01

    The Geological Sciences department at the University of Texas at El Paso (UTEP) hosted the EarthTech outreach program - a one-week intensive summer camp for low-income, at-risk high school students. The EarthTech program engaged students in STEM activities from geological and environmental sciences. Developed and led by university student-mentors with guidance from a supervising faculty member, the course engaged Upward Bound students with lectures, interactive projects, and excursions to local ecological preserves and geological sites around El Paso, Texas. Topics covered plant and animal distribution and diversity, water and soil dynamics, evolution and paleontology, geohazards, and planetary science. Field trips were combined with hands-on activities, including activities from DIG Texas teaching modules. The NSF-funded DIG Texas Instructional Blueprints project is organizing vetted, high quality online educational resources and learning activities into teaching modules. The modules follow a storyline and demonstrate congruency with the Next Generation Science Standards. Selected DIG Texas resources were included in the daily curriculum to complement the field trip and other hands-on activities. EarthTech students created ESRI Online GIS story maps in which they showed the locations of the field trips, incorporated photographs they had taken, and provided written reflections about their camp experiences. The DIG Texas project evaluation collected survey and interview data from the university student mentors throughout the week to ascertain the efficacy of the program. This poster presentation will include an overview of the program, including examples of work and evaluation results.

  16. Does urban sprawl hold down upward mobility?

    Science.gov (United States)

    Ewing, R.; Hamidi, Shima; Grace, James B.; Wei, Y.

    2016-01-01

    Contrary to the general perception, the United States has a much more class-bound society than other wealthy countries. The chance of upward mobility for Americans is just half that of the citizens of the Denmark and many other European countries. In addition to other influences, the built environment may contribute to the low rate of upward mobility in the U.S. This study tests the relationship between urban sprawl and upward mobility for commuting zones in the U.S. We examine potential pathways through which sprawl may have an effect on mobility. We use structural equation modeling to account for both direct and indirect effects of sprawl on upward mobility. We find that upward mobility is significantly higher in compact areas than sprawling areas. The direct effect, which we attribute to better job accessibility in more compact commuting zones, is stronger than the indirect effects. Of the indirect effects, only one, through the mediating variable income segregation, is significant.

  17. Upward Lightning in Brazil

    Schumann, C.; Saba, M. M.; Alves, J.; Warner, T. A.; Albrecht, R. I.; Bie, L. L.

    2012-12-01

    Observations of upward lightning from tall objects have been reported since 1939. Interest in this subject has grown recently, some of it because of the rapid expansion of wind power generation. Also, with the increasing number of tall buildings and towers, there will be a corresponding increase in the number of upward lightning flashes from these structures. Reports from recent field observations are beginning to address the nature of upward lightning initiation, but much still needs to be learned. Examples are studies of upward lightning from towers in winter thunderstorms in Japan (Wang and Takagi, 2010; and Lu et al., 2009) and summer thunderstorms in Europe (Miki et al., 2005; Flache et al., 2008; and Diendorfer et al., 2009; Zhou et al., 2011) and in North America (Mazur and Ruhnke, 2011; Hussein et al., 2011; Warner, 2011, and Warner et al., 2011). Up to January 2012, no upward flash had ever been registered in Brazil. With the help of some video cameras, we recorded 15 upward lightning which started from one of the towers located on Peak Jaraguá in the city of São Paulo. This paper describes the first results of this field campaign. A combination of high-speed video and standard definition video were used to record upward lightning flashes from multiple towers in Sao Paulo, Brazil, a city located in southeastern Brazil with a population over 10 million people, an average elevation of around 800 meters above sea level, and a flash density of 15 flashes/km2/year. Observations of 15 upward flashes made with these assets were analyzed along with BrasilDAT Lightning Detection Network and a lightning mapping array (LMA) and electric field sensors.

  18. Upward-going muons and neutrino oscillations

    Science.gov (United States)

    Fogli, G. L.; Lisi, E.; Marrone, A.

    1998-05-01

    The available upward-going muon data from the Kamiokande, Baksan, MACRO, IMB, and SuperKamiokande experiments are reviewed and combined. Bounds on the neutrino mass and mixing parameters are derived for oscillations in two and three flavors. These bounds are not in significant conflict with the oscillation solution to the atmospheric neutrino flavor anomaly observed in the sub-GeV and multi-GeV energy range. The combination of all the available atmospheric data tends to favor the νμνe channel with respect to the νμντ channel, and to disfavor the threefold maximal mixing scenario.

  19. Comparison of upwards splaying and upwards merging segmented normal faults

    Science.gov (United States)

    Freitag, U. A.; Sanderson, D. J.; Lonergan, L.; Bevan, T. G.

    2017-07-01

    A common model for normal fault growth involves a single fault at depth splaying upwards into a series of en-echelon segments. This model is applied to faults as well as a range of extension fractures, including veins, joints and igneous dykes. Examples of splaying growth fault systems in the Columbus Basin, offshore Trinidad, are presented. They include the commonly described upwards splaying type, but also one fault zone with an upward change from disconnected overlapping synthetic faults to a continuous fault. One fault zone with high-displacement fault segments is separated by a relay ramp at depth, becomes breached higher up, developing into a continuous fault at its upper part, where displacements are least. This example suggests that whilst kinematic linkage typically precedes geometric linkage in the evolution of relay ramps, low-displacement parts of a fault system may be geometrically linked whereas higher displacement areas are only kinematically linked.

  1. Upward social mobility and identity.

    Science.gov (United States)

    Destin, Mesmin; Debrosse, Régine

    2017-12-01

    As psychological research on socioeconomic status (SES) continues to expand, greater attention should be devoted to the influence of social mobility and the dynamic and malleable aspects of SES on people's lives. Status-based identity describes how people's socioeconomic circumstances relate to their broader sense of self and the meaning that they make of their own SES. Such an approach allows for complex study of the challenges and consequences of a change in SES. Research related to status-based identity suggests that although social mobility is often considered a signifier of reduced inequality, upward social mobility may also exacerbate other forms of inequality by instigating a destabilizing sense of status uncertainty that impairs motivation and well-being for class migrants.

    Fukumura, Shinobu; Watanabe, Toshihide; Takayama, Rumiko; Tsutsumi, Hiroyuki

    2015-01-01

    Paroxysmal tonic upward gaze is a childhood oculomotor syndrome characterized by episodes of conjugate upward deviation of the eyes. Its pathogenesis is unknown, and the etiology is heterogeneous. We describe a 2-year-old girl with Angelman syndrome who developed paroxysmal tonic upward gaze at 9 months of age. She presented with developmental delay, blond hair, jerky movements, ataxia, and epilepsy. Genetic testing revealed a maternal deletion of 15q11-13, confirming Angelman syndrome. This is the first report of Angelman syndrome complicated by paroxysmal tonic upward gaze. Both transient paroxysmal tonic upward gaze and Angelman syndrome have been associated with dopaminergic neurons. We speculate that the dopaminergic abnormalities present in Angelman syndrome may cause paroxysmal tonic upward gaze. Copyright © 2015 Elsevier Inc. All rights reserved.

  2. Constraints on Upward Migration of Hydraulic Fracturing Fluid and Brine

    Science.gov (United States)

    Flewelling, Samuel A; Sharma, Manu

    2014-01-01

    Recent increases in the use of hydraulic fracturing (HF) to aid extraction of oil and gas from black shales have raised concerns regarding potential environmental effects associated with predictions of upward migration of HF fluid and brine. Some recent studies have suggested that such upward migration can be large and that timescales for migration can be as short as a few years. In this article, we discuss the physical constraints on upward fluid migration from black shales (e.g., the Marcellus, Bakken, and Eagle Ford) to shallow aquifers, taking into account the potential changes to the subsurface brought about by HF. Our review of the literature indicates that HF affects a very limited portion of the entire thickness of the overlying bedrock and therefore, is unable to create direct hydraulic communication between black shales and shallow aquifers via induced fractures. As a result, upward migration of HF fluid and brine is controlled by preexisting hydraulic gradients and bedrock permeability. We show that in cases where there is an upward gradient, permeability is low, upward flow rates are low, and mean travel times are long (often >106 years). Consequently, the recently proposed rapid upward migration of brine and HF fluid, predicted to occur as a result of increased HF activity, does not appear to be physically plausible. Unrealistically high estimates of upward flow are the result of invalid assumptions about HF and the hydrogeology of sedimentary basins. PMID:23895673

    2012-03-01

    Full Text Available The observation of the actual behavior by economic decision makers in the lab and in the field justifies that bounded rationality has been a generally accepted assumption in many socio-economic models. The goal of this paper is to illustrate the difficulties involved in providing a correct definition of what a rational (or irrational agent is. In this paper we describe two frameworks that employ different approaches for analyzing bounded rationality. The first is a spatial segregation set-up that encompasses two optimization methodologies: backward induction and forward induction. The main result is that, even under the same state of knowledge, rational and non-rational agents may match their actions. The second framework elaborates on the relationship between irrationality and informational restrictions. We use the beauty contest (Nagel, 1995 as a device to explain this relationship.

    La observación del comportamiento de los agentes económicos tanto en el laboratorio como en la vida real justifica que la racionalidad acotada sea un supuesto aceptado en numerosos modelos socio-económicos. El objetivo de este artículo es ilustrar las dificultades que conlleva una correcta definición de qué es un agente racional (irracional. En este artículo se describen dos marcos que emplean diferentes metodologías para analizar la racionalidad acotada. El primero es un modelo de segregación espacial donde se contrastan dos metodologías de optimización: inducción hacia atrás y hacia adelante. El resultado principal es que, incluso con el mismo nivel de conocimiento, tanto agentes racionales como irracionales podrían coincidir en sus acciones. El segundo marco trabaja sobre la relación entre irracionalidad y restricción de información. Se utiliza el juego llamado “beauty contest” (Nagel 1995 como mecanismo para explicar dicha relación.

  7. Observations of simultaneous upward lightning leaders from multiple tall structures

    Science.gov (United States)

    Warner, Tom A.

    2012-11-01

    We present high-speed camera observations (up to 7200 images per second) and correlated electric field measurements of upward lightning leaders initiated simultaneously from multiple tall towers. Four towers spanning a horizontal distance of 2.9 km and ranging in height from 121 to 191 m, developed upward leaders following a nearby positive cloud-to-ground (+ CG) flash on 7/16/09 UT in Rapid City, South Dakota, USA during the summer thunderstorm season. The optical and electric field observations suggest that all four upward propagating leaders were positive polarity (i.e., upward negative lightning) and initiated simultaneously approximately 2 ms following the + CG return stroke. There was significant intracloud flash activity prior to the return stroke, and upward leader initiation coincided with the passage of horizontally extensive in-cloud negative breakdown following the + CG return stroke. This observation supports the idea that downward positive cloud-to-ground lightning can trigger upward negative lightning from multiple tall objects. Specifically, the triggering component is an area of horizontally propagating negative breakdown following the + CG return stroke that influences a broad area resulting in simultaneous or near-simultaneous, positive polarity upward leader initiation from multiple tall objects.

  13. A Spatial and Temporal Analysis of Upward Triggered Lightning

    2013-12-01

    Alana Ballweber, John H. Helsdon Jr., and Tom A. Warner South Dakota School of Mines and Technology Ten tall communication towers lining the ridge in Rapid City, South Dakota provide a unique opportunity to study the phenomenon of lightning-triggered upward lightning. The Upward Lightning Triggering Study (UPLIGHTS), seeks to determine if upward positive leaders are triggered from these towers by: (1) the approach of horizontally propagating negative stepped leaders associated with either intracloud development or following a positive cloud-to-ground (+CG) return stroke, and/or (2) a +CG return stroke as it propagates through a previously formed leader network near the towers. As part of the UPLIGHTS research, two separate lightning mapping devices were used to aid in a 3D re-creation of the triggering flash, a 3D digital interferometer and a Lightning Mapping Array. Through the use of these two devices, we present findings founded on the analysis of data collected from these assets during the 2013 storm season. Specifically, we quantify the spatial and temporal relationship of the triggering flash leader activity relative to the tall objects when upward leaders develop and when upward leaders fail to develop. Furthermore, the lightning mapping devices were correlated with high-speed optical and electrical field observations to provide a further insight as to why certain flashes trigger upward lightning from tall structures and others do not.

  18. A self-consistent upward leader propagation model

    The knowledge of the initiation and propagation of an upward moving connecting leader in the presence of a downward moving lightning stepped leader is a must in the determination of the lateral attraction distance of a lightning flash by any grounded structure. Even though different models that simulate this phenomenon are available in the literature, they do not take into account the latest developments in the physics of leader discharges. The leader model proposed here simulates the advancement of positive upward leaders by appealing to the presently understood physics of that process. The model properly simulates the upward continuous progression of the positive connecting leaders from its inception to the final connection with the downward stepped leader (final jump). Thus, the main physical properties of upward leaders, namely the charge per unit length, the injected current, the channel gradient and the leader velocity are self-consistently obtained. The obtained results are compared with an altitude triggered lightning experiment and there is good agreement between the model predictions and the measured leader current and the experimentally inferred spatial and temporal location of the final jump. It is also found that the usual assumption of constant charge per unit length, based on laboratory experiments, is not valid for lightning upward connecting leaders.

    For the past three years, upward lightning from ten towers located along the front range of the Black Hills have been observed using both standard- and high-speed cameras and electric field measurements. Multiple towers arranged in close proximity to each other combined with high cloud bases common during the warm season allow Rapid City, South Dakota to be an ideal location to observe upward lightning. The UPward LIGHtning Triggering Study (UPLIGHTS) was developed at South Dakota School of Mines and Technology in cooperation with the National Institute for Space Research in Brazil, to expand the instrumentation available for observation and analysis of the triggering flash type, component, and mechanism along with weather conditions that are favorable for upward lightning development. This project combines local weather observations, multiple electric field meters and field change sensors, and two interferometers with the previously used cameras. UPLIGHTS main goal is to use these resources to better understand the triggering/initiation of upward lightning from tall objects. Based on the analysis of previous years' observations, we proposed that the primary triggering flash type is a positive cloud-to-ground (+CG) in the vicinity of the towers. UPLIGHTS will attempt to determine if upward positive leaders are triggered from these towers by either 1) the approach of horizontally propagating negative stepped leaders associated with either intracloud development or following a +CG return stroke and/or 2) a +CG return stroke as it propagates through a previously formed leader network that is near the towers. The study will also examine the mechanism behind the initiation of upward leaders from multiple tall objects during same flash. This talk will touch on some concepts of previous work along with a summary of summer 2012, the first of three UPLIGHTS seasons.

    Full Text Available This paper investigates the upwards intensifiers (adverbs of intensifying in the English, German and Croatian language. Intensity as an important human cognitive category, and language expressivity is differently treated in grammars and dictionaries of all three languages, especially with respect to different degrees of intensity. In this paper we argue that it is possible to model a typology of upwards adverb intensifiers in the three languages, according to their morphosyntactic and semantic aspects. When it comes to intensifiers, it is necessary to describe which collocates are modified by intensifiers and which semantic fields the collocates belong to. The results of the corpus analysis based on Harry Potter novels show that all the three languages express the category of the upwards intensity in the same way: the number of intensifiers is similar, the collocates mostly belong to the same semantic fields and word classes, they have similar syntactic functions.

  1. Time dependent evaluation of the lightning upward connecting leader inception

    The evaluation of the upward connecting leader inception from a grounded structure has generally been performed neglecting the effect of the propagation of the downward stepped leader. Nevertheless, field observations suggest that the space charge produced by streamer corona and aborted upward leaders during the approach of the downward lightning leader can influence significantly the initiation of stable upward positive leaders. Thus, a physical leader inception model is developed, which takes into account the electric field variations produced by the descending leader during the process of inception. Also, it accounts for the shielding effect produced by streamer corona and unstable leaders formed before the stable leader inception takes place. The model is validated by comparing its predictions with the results obtained in long gap experiments and in an altitude triggered lightning experiment. The model is then used to estimate the leader inception conditions for free standing rods as a function of tip radius and height. It is found that the rod radius slightly affects the height of the downward leader tip necessary to initiate upward leaders. Only an improvement of about 10% on the lightning attractiveness can be reached by using lightning rods with an optimum radius. Based on the obtained results, the field observations of competing lightning rods are explained. Furthermore, the influence of the average stepped leader velocity on the inception of positive upward leaders is evaluated. The results obtained show that the rate of change of the background electric field produced by a downward leader descent largely influences the conditions necessary for upward leader initiation. Estimations of the leader inception conditions for the upper and lower limit of the measured values of the average downward lightning leader velocity differ by more than 80%. In addition, the striking distances calculated taking into account the temporal change of the background field are

    2017-05-01

    Veterans recently returned from Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) experience many health and mental health problems after deployment. These OEF/OIF veterans are applying and appealing for veterans' disability compensation (VDC) at rapidly increasing rates, often for "invisible conditions" such as posttraumatic stress disorder. Little is known about how veterans experience the process of applying and receiving VDC. In-depth qualitative interviews were conducted with OEF/OIF veterans ages 35 and younger (N = 18). This article addresses how veterans perceive themselves, and other veterans, of being deserving and undeserving of VDC. Veterans' rationales can be categorized into four primary areas: (1) risking and suffering, (2) the cause of the condition, (3) intentions to become self-sufficient, and (4) putting VDC to "good use." © 2017 National Association of Social Workers.

    This meta-analysis examined the strength of association between upward counterfactual thinking and depressive symptoms. Forty-two effect sizes from a pooled sample of 13,168 respondents produced a weighted average effect size of r=.26, pdesign (cross-sectional versus longitudinal). Significant effect size heterogeneity was observed across sample types, methods of assessing upward counterfactual thinking, and types of depression scale. Significant positive effects were found in studies that employed samples of bereaved individuals, older adults, terminally ill patients, or university students, but not adolescent mothers or mixed samples. Both number-based and Likert-based upward counterfactual thinking assessments produced significant positive effects, with the latter generating a larger effect. All depression scales produced significant positive effects, except for the Psychiatric Epidemiology Research Interview. Research and theoretical implications are discussed in relation to cognitive theories of depression and the functional theory of upward counterfactual thinking, and important gaps in the extant research literature are identified.

  1. The war veteran identity

    Directory of Open Access Journals (Sweden)

    Marković-Savić Olivera S.

    2015-01-01

    Full Text Available The paper discusses how war veterans perceive themselves and how they answer the question 'Who am I?'. War veterans face many challenges in the process of re-socialization from a state of war and war traumatization to a peacetime society. There are several reasons why their re-socialization is a slow process: the first one is that a war engagement is in itself a highly stressful situation which carries traumas of different degrees, the other reason is the changed system of values in relation to war engagement. Namely, at the time they went to war, they had a strong social support, but at the time of their return and today this support is lost to the point of judgment. And the third reason which limits their re-socialization is the situation of social transition they found on their return from war, which specifically means that a large percentage of the population in general, and thus the war veterans after returning from the war, lost their jobs, creating a large social group of 'transition losers'. Such a condition often generates an identity crisis. This set of socio-cultural circumstances together with the ontological insecurity carried by war trauma generate an identity crisis, which is manifested among the respondents in nihilistic answers when responding to questions about their own personality. Studying the identity of war veterans, it was found that a strong attachment to the veteran identity is dominant. In fact, this paper discusses the different ways in which this attachment is refracted in the personality and identity of subjects, from negative attitudes to the pride in belonging to a group of war veterans and personal fulfillment in the activism in associations of war participants.

  3. Effect of upward seepage on bedload transport rate

    Directory of Open Access Journals (Sweden)

    Xiao-xie Liu

    2014-04-01

    Full Text Available The paper presents an investigation of injection effects on the bedload transport rate. According to dimensional analysis, two dimensionless groups, an Einstein's parameter group and a modified densimetric Froude number group, were chosen to examine how injection affects the bedload transport rate. Experimental studies were conducted in an open-channel flume with an upward seepage zone. The sediment particles used for the test were 0.9 mm in diameter. The experimental results show that an increase in the injection velocity causes a reduction in the shear velocity excess, which is defined as the difference between the shear and critical shear velocities, leading to a reduction in the bedload transport rate. The equation for predicting the bedload transport rate in the presence of upward seepage was derived empirically. The proposed prediction method is suitable for engineering practice, since it only requires the undisturbed flow condition, properties of sediment particles, and the injection velocity.

    Discharges originating from laboratory upward leaders are studied experimentally with a configuration consisting of two parallel vertical rods at ground and an elevated plane. Flashover probability of each rod, the effect of gap configuration on that probability, and the shielding effect of the taller rod on the smaller one are investigated. Experimental results are analyzed taking into account the deviation of time to flashover of the gap. Application of the results to the case of natural lightning is also discussed.

  6. Bound states and the Bekenstein bound

    Energy Technology Data Exchange (ETDEWEB)

    Bousso, Raphael

    2003-10-16

    We explore the validity of the generalized Bekenstein bound, S<= pi M a. We define the entropy S as the logarithm of the number of states which have energy eigenvalue below M and are localized to a flat space region of width alpha. If boundary conditions that localize field modes are imposed by fiat, then the bound encounters well-known difficulties with negative Casimir energy and large species number, as well as novel problems arising only in the generalized form. In realistic systems, however, finite-size effects contribute additional energy. We study two different models for estimating such contributions. Our analysis suggests that the bound is both valid and nontrivial if interactions are properly included, so that the entropy S counts the bound states of interacting fields.

    2015-03-19

    This paper introduces and motivates the need for a new methodology for determining upper bounds on the uncertainties in simulations of engineered systems due to limited fidelity in the composite continuum-level physics models needed to simulate the systems. We show that traditional uncertainty quantification methods provide, at best, a lower bound on this uncertainty. We propose to obtain bounds on the simulation uncertainties by first determining bounds on the physical quantities or processes relevant to system performance. By bounding these physics processes, as opposed to carrying out statistical analyses of the parameter sets of specific physics models or simply switching out the available physics models, one can obtain upper bounds on the uncertainties in simulated quantities of interest.

    Species distribution models are increasing in popularity for mapping suitable habitat for species of management concern. Many investigators now recognize that extrapolations of these models with geographic information systems (GIS) might be sensitive to the environmental bounds of the data used in their development, yet there is no recommended best practice for "clamping" model extrapolations. We relied on two commonly used modeling approaches: classification and regression tree (CART) and maximum entropy (Maxent) models, and we tested a simple alteration of the model extrapolations, bounding extrapolations to the maximum and minimum values of primary environmental predictors, to provide a more realistic map of suitable habitat of hybridized Africanized honey bees in the southwestern United States. Findings suggest that multiple models of bounding, and the most conservative bounding of species distribution models, like those presented here, should probably replace the unbounded or loosely bounded techniques currently used [Current Zoology 57 (5): 642-647, 2011].

  1. Shallowing-upward cycles in the Middle Proterozoic Altyn Formation.

    Science.gov (United States)

    White, Brian

    1981-11-12

    Phanerozoic carbonate rocks commonly contain cycles, a few metres thick, which were deposited during progressive shallowing of their oceanic environment 1 . Each cycle represents a deepening of water in a nearshore area, followed by the accumulation of sediments up to sea level. The causes of the water deepening which begins each cycle are rarely known. Possibilities include tectonic activity that affected the depositional basin and changes in ocean volume due to the expansion and contraction of ice sheets. I report here that similar cycles occur in the Middle Proterozoic Altyn Formation, part of the Belt Supergroup 2 . The cycles are probably related to vertical tectonic activity which influenced sedimentation in the Belt basin. The presence of shallowing-upward cycles in the Altyn Formation shows that such cycles are not confined to the Phanerozoic. Other Precambrian sequences should be examined to see if they too contain cycles. Where such cycles are found they may give important information about Precambrian tectonism and glaciation.

    Depression has been linked to counterfactual thinking in many behavioral studies, but the direction of this effect remains disputed. In the current study, the relationship between depression and counterfactual thinking was examined using the event-related potential (ERP) technique. In a binary choice gambling task, outcome feedback of the chosen option and that of the alternative option were both provided, so as to elicit the process of counterfactual comparison. By investigating ERP signals in response to outcome presentation, we discovered that when the fictive outcome was better or worse than the factual outcome, the amplitude of the P3 component was positively correlated with individual levels of depression, but not levels of anxiety. These results indicate that depression strengthens both upward counterfactual thinking and downward counterfactual thinking. The implication of this finding to clinical research is discussed.

  3. Suicide among War Veterans

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available Studies aiming to identify if war veterans are at higher risk of suicide have often produced inconsistent results; this could be due to the complexity of comparisons and different methodological approaches. It should be noted that this contingent has many risk factors, such as stressful exposures, wounds, brain trauma and pain syndrome. Most recent observations confirm that veterans are really more likely to die of suicide as compared to the general population; they are also more likely to experience suicidal ideation and suffer from mental health problems. Suicides are more frequent in those who develop PTSD, depression and comorbid states due to war exposure. Combat stress and its’ frequency may be an important factor leading to suicide within the frame of the stress-vulnerability model. According to this model, the effects of stress may interact with social factors, interpersonal relations and psychological variables producing suicidal tendencies. Modern understanding of stress-vulnerability mechanisms based on genetic predispositions, early life development, level of exposure to stress and stress-reactivity together with interpersonal aspects may help to build more effective suicide prevention programs based on universal/selective/indicated prevention principles.

  7. Virial Expansion Bounds

    Tate, Stephen James

    2013-10-01

    In the 1960s, the technique of using cluster expansion bounds in order to achieve bounds on the virial expansion was developed by Lebowitz and Penrose (J. Math. Phys. 5:841, 1964) and Ruelle (Statistical Mechanics: Rigorous Results. Benjamin, Elmsford, 1969). This technique is generalised to more recent cluster expansion bounds by Poghosyan and Ueltschi (J. Math. Phys. 50:053509, 2009), which are related to the work of Procacci (J. Stat. Phys. 129:171, 2007) and the tree-graph identity, detailed by Brydges (Phénomènes Critiques, Systèmes Aléatoires, Théories de Jauge. Les Houches 1984, pp. 129-183, 1986). The bounds achieved by Lebowitz and Penrose can also be sharpened by doing the actual optimisation and achieving expressions in terms of the Lambert W-function. The different bound from the cluster expansion shows some improvements for bounds on the convergence of the virial expansion in the case of positive potentials, which are allowed to have a hard core.

  11. Upward communication about cancer screening: adolescent daughter to mother.

    Mosavel, Maghboeba; Ports, Katie A

    2015-01-01

    Substantial breast and cervical cancer disparities exist in the United States, particularly among African American women with low socioeconomic status. There is considerable potential for discussions about cancer prevention between mothers and daughters. However, upward communication, from child to parent, remains a relatively novel research area, and it remains unclear how receptive mothers would be to messages from their daughter about cancer, a topic that may be considered culturally inappropriate for daughters to initiate. In this study, the authors simulated cancer message delivery to daughters and then conducted direct observation of daughters as they recalled and shared the message with their mother or female elder. The authors found that daughters were able to successfully recall and deliver a cancer appeal to their mother and mothers were generally receptive to this message. Not only did mothers listen to their daughters' appeals, but also daughters' knowledge of cancer was considerably improved by the opportunity to educate her female elder. Moreover, daughters' nonverbal communication suggested a surprisingly relaxed demeanor. The potential of young people to have an effect on the screening behavior of their female elders is very promising in terms of reducing cancer disparities.

    Test data on canonical weapon-like fixtures are used to validate previously developed analytical bounding results. The test fixtures were constructed to simulate (but be slightly worse than) weapon ports of entry but have known geometries (and electrical points of contact). The exterior of the test fixtures exhibited exterior resonant enhancement of the incident fields at the ports of entry with magnitudes equal to those of weapon geometries. The interior consisted of loaded transmission lines adjusted to maximize received energy or voltage but incorporating practical weapon geometrical constraints. New analytical results are also presented for bounding the energies associated with multiple bolt joints and for bounding the exterior resonant enhancement of the exciting fields.

    Rostaminia, Ghazaleh; Peck, Jennifer; Quiroz, Lieschen; Shobeiri, S. Abbas

    2016-01-01

    Objective The aim of study was to compare digital palpation with the levator plate lift measured by endovaginal and transperineal dynamic ultrasound. Methods Dynamic transperineal and endovaginal ultrasound were performed as part of multicompartmental pelvic floor functional assessment. Patients were instructed to perform Kegels while a probe captured the video clip of the levator plate movement at rest and during contraction in 2D mid-sagittal posterior view. We measured the distance between the levator plate and the probe on endovaginal ultrasound as well as the distance between the levator plate and the gothic arch of the pubis in transperineal ultrasound. The change in diameter (lift) and a levator plate lift ratio (lift / rest) x 100) were calculated. Pelvic floor muscle strength was assessed by digital palpation and divided into functional and non-functional groups using the Modified Oxford Scale (MOS). Mean differences in levator plate upward lifts were compared by MOS score using student t-tests and analysis of variance (ANOVA). Results 74 women were available for analysis. The mean age was 55 (SD±11.9). When measured by vaginal dynamic ultrasound, mean values of the lift and lift/rest ratio increased with increasing MOS score (ANOVA p=0.09 and p=0.04, respectively). When MOS scores were categorized to represent non-functional (MOS 0-1) and functional (MOS 2-5) muscle strength groups, the mean values of the lift (3.2 mm vs. 4.6 mm, p=0.03) and lift/rest ratio (13% vs 20%, p=0.01) were significantly higher in women with functional muscle strength. All patients with ≥ 30% lift detected by vaginal ultrasound had functional muscle strength. Conclusions Greater levator plate lift ratio detected by dynamic endovaginal ultrasound was associated with higher muscle strength as determined by MOS. This novel measurement can be incorporated into ultrasound evaluation of the levator ani function. PMID:26333568

  2. Tree Waves Upward Migration in the Altai Mountains, Siberia

    2017-04-01

    The phenomenon of "tree waves" (hedges and ribbons) formation within the alpine ecotone in Altai Mountains and its response to observed air temperature increase was considered. At the upper limit of tree growth Siberian pine (Pinus sibirica) forms hedges on windward slopes and ribbons on the leeward ones. Hedges were formed by prevailing winds and oriented along winds direction. Ribbons were formed by snow blowing and accumulating on the leeward slope and perpendicular to the prevailing winds, as well as to the elevation gradient. Hedges were always linked with microtopography features, whereas ribbons were not. Trees are migrating upward by waves and new ribbons and hedges are forming at or near tree line, whereas at lower elevations ribbons and hedges are being transformed into closed forests. Time series of high-resolution satellite scenes (from 1968 to 2010) indicated an upslope shift in the position ribbons averaged 155±26 m (or 3.7 m yr -1) and crown closure increased (about 35-90%). The hedges advance was limited by poor regeneration establishment and was negligible. Regeneration within the "ribbon zone" was approximately 2.5 times (5060 vs 2120 ha -1) higher then within the "hedges zone". During the last four decades, Siberian pine in both hedges and ribbons strongly increased its growth increment and recent tree growth rate for 50 year old trees was about twice higher than recorded for similarly aged trees at the beginning of the 20th century. Growth increment increase was strongly correlated with CO2 concentration in the ambient air (R2 = 0.9), which may indicated CO2- fertilization. Hedges and ribbons are phenomena that are widespread within the southern and northern Siberian Mountains

    Sexual trauma survivors are reluctant to disclose such a history due to stigma. This is likely the case when estimating the prevalence of sexual trauma experienced in the military. The Veterans Health Administration has a program by which all former US military service members (Veterans) are screened for military sexual trauma (MST) using a questionnaire. Administrative data on MST screens and a change of status from an initial negative answer to positive and natural language processing (NLP) on electronic medical notes to extract concepts related to MST were used to refine initial estimates of MST among a random sample of 20,000 Veterans. The initial MST positive screen of 15.4% among women was revised upward to 21.8% using administrative data and further to 24.5% by adding NLP results. The overall estimate of MST status in women and men in this sample was revised from 8.1% to 13.1% using both data elements.

  9. Born Level Bound States

    Science.gov (United States)

    Hoyer, Paul

    2017-05-01

    Bound state poles in the S-matrix of perturbative QED are generated by the divergence of the expansion in α . The perturbative corrections are necessarily singular when expanding around free, {O}( α ^0 ) in and out states that have no overlap with finite-sized atomic wave functions. Nevertheless, measurables such as binding energies do have well-behaved expansions in powers of α (and log α ). It is desirable to formulate the concept of "lowest order" for gauge theory bound states such that higher order corrections vanish in the α → 0 limit. This may allow to determine a lowest order term for QCD hadrons which incorporates essential features such as confinement and chiral symmetry breaking, and thus can serve as the starting point of a useful perturbative expansion. I discuss a "Born" (no loop, lowest order in \\hbar ) approximation. Born level states are bound by gauge fields which satisfy the classical field equations. Gauss' law determines a distinct field A^0({\\varvec{x}}) for each instantaneous position of the charges. A Poincaré covariant boundary condition for the gluon field leads to a confining potential for q\\bar{q} and qqq states. In frames where the bound state is in motion the classical gauge field is obtained by a Lorentz boost of the rest frame field.

    There have been ubiquitous observations of wave-like motions in the solar atmosphere for decades. Recent improvements to space- and ground-based observatories have allowed the focus to shift to smaller magnetic structures on the solar surface. In this paper, high-resolution ground-based data taken using the Swedish 1 m Solar Telescope is combined with co-spatial and co-temporal data from the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO) satellite to analyze running penumbral waves (RPWs). RPWs have always been thought to be radial wave propagation that occurs within sunspots. Recent research has suggested that they are in fact upwardly propagating field-aligned waves (UPWs). Here, RPWs within a solar pore are observed for the first time and are interpreted as UPWs due to the lack of a penumbra that is required to support RPWs. These UPWs are also observed co-spatially and co-temporally within several SDO/AIA elemental lines that sample the transition region and low corona. The observed UPWs are traveling at a horizontal velocity of around 17 ± 0.5 km s{sup –1} and a minimum vertical velocity of 42 ± 21 km s{sup –1}. The estimated energy of the waves is around 150 W m{sup –2}, which is on the lower bound required to heat the quiet-Sun corona. This is a new, yet unconsidered source of wave energy within the solar chromosphere and low corona.

  16. Access to Care Among Nonelderly Veterans.

    2016-03-01

    Veteran access to care is an important policy issue that has not previously been examined with population-based survey data. This study compares access to care for nonelderly adult Veterans versus comparable non-Veterans, overall and within subgroups defined by simulated eligibility for health care from the Veterans Health Administration and by insurance status. We use household survey data from the Medical Expenditure Panel Survey from 2006 to 2011. We use iterative proportional fitting to standardize (control for) differences in age, sex, income, medical conditions, disability, Census region, and Metropolitan Statistical Area. Nonelderly Veterans and comparable non-Veterans. For medical, dental, and prescription medicine treatments, we use 4 access measures: delaying care, inability to obtain care, perceiving delay as a big problem, and perceiving inability to obtain care as a big problem. We also examine having a usual source of care. Frequencies of access barriers are similar for nonelderly Veterans and comparable non-Veterans for dental and prescription medicine treatments. For medical treatment, we find that Veterans eligible for VA health care and Veterans with VA use who are uninsured report fewer access problems than the comparable non-Veteran populations for 2 measures: inability to obtain care and reporting inability to obtain care as a big problem. Our results show that uninsured Veterans, the most policy-relevant group, have better access to care than comparable non-Veterans. Our results highlight the importance of adjusting Veteran and non-Veteran comparisons to account for the higher than average health care needs of Veterans.

  1. Gender, race & the veteran wage gap.

    Science.gov (United States)

    Vick, Brandon; Fontanella, Gabrielle

    2017-01-01

    This paper analyzes earnings outcomes of Iraq/Afghanistan-era veterans. We utilize the 2009-2013 American Community Survey and a worker-matching methodology to decompose wage differences between veteran and non-veteran workers. Among fully-employed, 25-40 year-olds, veteran workers make 3% less than non-veteran workers. While male veterans make 9% less than non-veterans, female and black veterans experience a wage premium (2% and 7% respectively). Decomposition of the earnings gap identifies some of its sources. Relatively higher rates of disability and lower rates of educational attainment serve to increase the overall wage penalty against veterans. However, veterans work less in low-paying occupations than non-veterans, serving to reduce the wage penalty. Finally, among male and white subgroups, non-veterans earn more in the top quintile due largely to having higher educational attainment and greater representation in higher-paying occupations, such as management.

  3. Bound Exciton Complexes

    Science.gov (United States)

    Meyer, B. K.

    In the preceding chapter, we concentrated on the properties of free excitons. These free excitons may move through the sample and hit a trap, a nonradiative or a radiative recombination center. At low temperatures, the latter case gives rise to either deep center luminescence, mentioned in Sect. 7.1 and discussed in detail in Chap. 9, or to the luminescence of bound exciton complexes (BE or BEC). The chapter continues with the most prominent of these BECs, namely A-excitons bound to neutral donors. The next aspects are the more weakly BEs at ionized donors. The Sect. 7.4 treats the binding or localization energies of BEC from a theoretical point of view, while Sect. 7.5 is dedicated to excited states of BECs, which contain either holes from deeper valence bands or an envelope function with higher quantum numbers. The last section is devoted to donor-acceptor pair transitions. There is no section devoted specifically to excitons bound to neutral acceptors, because this topic is still partly controversially discussed. Instead, information on these A0X complexes is scattered over the whole chapter, however, with some special emphasis seen in Sects. 7.1, 7.4, and 7.5.

    2003-03-01

    The asymptotic perturbation (AP) method is applied to the study of the nonlinear Klein-Gordon equation in 3+1 dimensions with harmonic potential and external periodic excitation supposed to be in primary resonance with the frequency of a generic mode. The AP method uses two different procedures for the solutions: introducing an asymptotic temporal rescaling and balancing of the harmonic terms with a simple iteration. Standard quantum mechanics can be used to derive the lowest order approximate solution and amplitude and phase modulation equations are obtained. External force-response and frequency-response curves are found and the existence of dromions trapped in bound states is demonstrated.

  6. Self Induced Buoyant Blow Off in Upward Flame Spread on Thin Solid Fuels

    ) is as follows: The observed one-sided extinction is a blow- off induced by buoyant entrainment. It is known that the flammable diffusion flame regime is bounded by quenching and blow ]off limits when varying incoming air velocity. The narrowest samples tested (between 2 and 5 cm) begin within the flammable range, but as the flame grows, the buoyancy driven air velocity increases at the neighborhood of the flame base. The initially stable flame crosses the extinguishment boundary resulting in a flame blow-off. When one-side of the flame extinguishes, the remaining side shrinks due to the reduced heat transfer to the solid. This reduces the induced velocity and the flame becomes stable. It is proposed that this may have implications to upward flame growth beyond this experiment.

    Despite good theoretical and empirical rationale for assessing tendencies to make upward and downward physical appearance comparisons no measure for these specific constructs exists. The present work developed and tested the psychometric properties of upward and downward physical appearance comparison scales. The scales were administered to participants (N=224) along with measures of general appearance comparison tendencies, body image, disordered eating, Antifat and Antigay attitudes. The scales displayed good psychometric properties. Importantly, the upward but not downward physical appearance comparison scale predicted lower Appearance Evaluation and higher EAT-26 scores. Conversely, the downward but not upward physical appearance comparison scale predicted higher Appearance Evaluation and greater Antifat Attitudes (Dislike). The scales were unrelated to a nonappearance related construct. These new measures fill a gap in the literature and may be of benefit to researchers interested in body image, appearance concerns, eating disorders, social comparison, and obesity prejudice.

    Military sexual trauma (MST) is the Veteran Health Administration's (VHA) term for sexual assault and/or sexual harassment that occurs during military service. The experience of MST is associated with a variety of mental health conditions. Preliminary research suggests that MST may be associated with homelessness among female Veterans, although to date MST has not been examined in a national study of both female and male homeless Veterans. To estimate the prevalence of MST, examine the association between MST and mental health conditions, and describe mental health utilization among homeless women and men. National, cross-sectional study of 126,598 homeless Veterans who used VHA outpatient care in fiscal year 2010. All variables were obtained from VHA administrative databases, including MST screening status, ICD-9-CM codes to determine mental health diagnoses, and VHA utilization. Of homeless Veterans in VHA, 39.7 % of females and 3.3 % of males experienced MST. Homeless Veterans who experienced MST demonstrated a significantly higher likelihood of almost all mental health conditions examined as compared to other homeless women and men, including depression, posttraumatic stress disorder, other anxiety disorders, substance use disorders, bipolar disorders, personality disorders, suicide, and, among men only, schizophrenia and psychotic disorders. Nearly all homeless Veterans had at least one mental health visit and Veterans who experienced MST utilized significantly more mental health visits compared to Veterans who did not experience MST. A substantial proportion of homeless Veterans using VHA services have experienced MST, and those who experienced MST had increased odds of mental health diagnoses. Homeless Veterans who had experienced MST had higher intensity of mental health care utilization and high rates of MST-related mental health care. This study highlights the importance of trauma-informed care among homeless Veterans and the success of VHA homeless

  17. Refining Multivariate Value Set Bounds

    Science.gov (United States)

    Smith, Luke Alexander

    Over finite fields, if the image of a polynomial map is not the entire field, then its cardinality can be bounded above by a significantly smaller value. Earlier results bound the cardinality of the value set using the degree of the polynomial, but more recent results make use of the powers of all monomials. In this paper, we explore the geometric properties of the Newton polytope and show how they allow for tighter upper bounds on the cardinality of the multivariate value set. We then explore a method which allows for even stronger upper bounds, regardless of whether one uses the multivariate degree or the Newton polytope to bound the value set. Effectively, this provides an alternate proof of Kosters' degree bound, an improved Newton polytope-based bound, and an improvement of a degree matrix-based result given by Zan and Cao.

    2010-02-01

    Women veterans are three to four times more likely than non-veteran women to become homeless. However, their risk factors for homelessness have not been defined. Case-control study of non-institutionalized homeless women veterans (n533) and age-matched housed women veterans (n=165). Health, health care, and factors associated with homelessness were assessed using multiple logistic regression with a Monte Carlo algorithm to estimate exact standard errors of the model coefficients and p-values. Characteristics associated with homelessness were sexual assault during military service, being unemployed, being disabled, having worse overall health, and screening positive for an anxiety disorder or post-traumatic stress disorder. Protective factors were being a college graduate or married. Efforts to assess housed women veterans' risk factors for homelessness should be integrated into clinical care programs within and outside the Veterans Administration. Programs that work to ameliorate risk factors may prevent these women's living situations from deteriorating over time.

    In response to the growing interest in bounding error approaches, the editors of this volume offer the first collection of papers to describe advances in techniques and applications of bounding of the parameters, or state variables, of uncertain dynamical systems. Contributors explore the application of the bounding approach as an alternative to the probabilistic analysis of such systems, relating its importance to robust control-system design.

  18. with Bounded Failure Intensity

    Directory of Open Access Journals (Sweden)

    Preeti Wanti Srivastava

    2011-01-01

    Full Text Available This paper deals with the Bayes prediction of the future failures of a deteriorating repairable mechanical system subject to minimal repairs and periodic overhauls. To model the effect of overhauls on the reliability of the system a proportional age reduction model is assumed and the 2-parameter Engelhardt-Bain process (2-EBP is used to model the failure process between two successive overhauls. 2-EBP has an advantage over Power Law Process (PLP models. It is found that the failure intensity of deteriorating repairable systems attains a finite bound when repeated minimal repair actions are combined with some overhauls. If such a data is analyzed through models with unbounded increasing failure intensity, such as the PLP, then pessimistic estimates of the system reliability will arise and incorrect preventive maintenance policy may be defined. On the basis of the observed data and of a number of suitable prior densities reflecting varied degrees of belief on the failure/repair process and effectiveness of overhauls, the prediction of the future failure times and the number of failures in a future time interval is found. Finally, a numerical application is used to illustrate the advantages from overhauls and sensitivity analysis of the improvement parameter carried out.

  19. Look Up for Healing: Embodiment of the Heal Concept in Looking Upward.

    N D Leitan

    Full Text Available Conceptual processing may not be restricted to the mind. The heal concept has been metaphorically associated with an "up" bodily posture. Perceptual Symbol Systems (PSS theory suggests that this association is underpinned by bodily states which occur during learning and become instantiated as the concept. Thus the aim of this study was to examine whether processing related to the heal concept is promoted by priming the bodily state of looking upwards.We used a mixed 2x2 priming paradigm in which 58 participants were asked to evaluate words as either related to the heal concept or not after being primed to trigger the concept of looking up versus down (Direction--within subjects. A possible dose-response effect of priming was investigated via allocating participants to two 'strengths' of prime, observing an image of someone whose gaze was upward/downward (low strength and observing an image of someone whose gaze was upward/downward while physically tilting their head upwards or downwards in accord with the image (high strength (Strength--between subjects.Participants responded to words related to heal faster than words unrelated to heal across both "Strength" conditions. There was no evidence that priming was stronger in the high strength condition.The present study found that, consistent with a PSS view of cognition, the heal concept is embodied in looking upward, which has important implications for cognition, general health, health psychology, health promotion and therapy.

  1. ExtremeBounds: Extreme Bounds Analysis in R

    Directory of Open Access Journals (Sweden)

    Marek Hlavac

    2016-08-01

    Full Text Available This article introduces the R package ExtremeBounds to perform extreme bounds analysis (EBA, a sensitivity test that examines how robustly the dependent variable of a regression model is related to a variety of possible determinants. ExtremeBounds supports Leamer's EBA that focuses on the upper and lower extreme bounds of regression coefficients, as well as Sala-i-Martin's EBA which considers their entire distribution. In contrast to existing alternatives, it can estimate models of a variety of user-defined sizes, use regression models other than ordinary least squares, incorporate non-linearities in the model specification, and apply custom weights and standard errors. To alleviate concerns about the multicollinearity and conceptual overlap of examined variables, ExtremeBounds allows users to specify sets of mutually exclusive variables, and can restrict the analysis to coefficients from regression models that yield a variance inflation factor within a prespecified limit.

    Wakefield, Bonnie J; Tripp-Reimer, Toni; Rosenbaum, Marcy E; Rosenthal, Gary E

    2007-06-01

    The objective of the study was to examine veterans' perceptions of problems and benefits of outsourcing inpatient care from Veterans Affairs (VA) hospitals to private sector hospitals. Primary data were collected from a cross-section of 42 veterans who were VA users and nonusers using focus groups. Focus group discussion examined reasons patients use VA care, differences between VA and civilian care, positive and negative impacts of outsourcing, and special needs of veterans. Analyses revealed five domains related both to use of VA services and perceptions of outsourcing: costs, access, quality of care, contract (i.e., a covenant between veterans and the U.S. government), veteran milieu, and special needs. Participants identified a variety of potential positive and negative impacts. In general, veterans perceived more advantages than disadvantages to outsourcing VA care but still expressed significant concerns related to outsourcing. These issues should be considered in the development of future policy toward outsourcing VA care to the private sector.

    2000-06-01

    Full Text Available An experiment has been performed to determine the upward water-leaving radiance by non-contact measurement of the total upward and downward radiance above the sea surface from a moving ship. The method for achieving this aim is described: the radiance meters are both tilted in such a way that the upward radiance meter can 'see' that part of the measured downward radiance which would be reflected if the water surface were smooth and which is not derived directly from solar glitter. Both meters are firmly fixed in a special frame, which ensures that the required orientation is the most probable one. Time records of the measured parameters are analysed. The results are presented in several forms: frequency (histogram analysis appears to be the most promising one.

  5. Grassroots development and upwards accountabilities: tensions in the reconstruction of Aceh's fishing industry.

    Science.gov (United States)

    Dixon, Rowan; McGregor, Andrew

    2011-01-01

    This article explores the tensions between aid funding and grassroots development goals in the context of post-disaster fisheries reconstruction in Aceh, Indonesia. We argue that both short- and long-term grassroots goals are distorted by upward accountability requirements which lead to unsatisfactory aid outcomes. Our analysis employs the concept of aid webs and draws on fifty-one formal interviews with stakeholders in Aceh in 2007/2008. The findings initially concentrate on the impacts of upward accountability on project cycles, with a particular focus on the problematic incorporation of private boat-building contractors and commercial values during the implementation phase. We then discuss the more subtle, long-term impacts of upward accountability on the professionalization of community institutions — in this case, the Panglima Laot Lhok. We conclude with a few observations about the hybrid institutions — combining elements of local and development cultures — that are produced within the current political economy of aid.

  6. Study of TeV Neutrinos with Upward Showering Muons in Super-Kamiokande

    CERN Document Server

    Desai, S

    2007-01-01

    A subset of neutrino-induced upward through-going muons in the Super-Kamiokande detector consists of high energy muons which lose energy through radiative processes such as bremsstrahlung, e^{+} e^{-} pair production and photonuclear interactions. These ``upward showering muons'' comprise an event sample whose mean parent neutrino energy is approximately 1 TeV. We show that the zenith angle distribution of upward showering muons is consistent with negligible distortion due to neutrino oscillations, as expected of such a high-energy neutrino sample. We present astronomical searches using these high energy events, such as those from WIMP annihilations in the Sun, Earth and Galactic Center, some suspected point sources, as well as searches for diffuse flux from the interstellar medium.

Seventy-six psychology students were categorized in an intermediate position with respect to other faculties. Stability was manipulated at three levels: stable, upwardly unstable, and downwardly unstable. Data on strength of comparison, comparison for enhancing, comparison for evaluation, and ingroup identification were collected. Results revealed that in the stable condition, participants were equally engaged in both upward and downward comparison. In the upwardly unstable condition, participants were more likely to compare themselves with the high-status group, whereas in the downwardly unstable condition, they were more likely to choose a downward comparison. In this latter condition, both downward comparison for enhancement and in-group identification were lower than in other conditions. © 2012 The British Psychological Society.

  14. Unemployment, earnings and enrollment among post 9/11 veterans.

    Science.gov (United States)

    Kleykamp, Meredith

    2013-05-01

    This paper examines three outcomes characterizing different aspects of post 9/11 veterans' economic reintegration to civilian life: unemployment, earnings and college enrollment, using Current Population Survey data from 2005 to 2011. Analyses include interactions of veteran status with sex, race/ethnicity and educational attainment to evaluate whether diverse veterans experience diverse consequences of service. In brief, I find that the basic unemployment differences between veterans and non-veterans often reported in the media understate the effect of military service on unemployment for men, since veterans have other characteristics that are associated with higher employment rates. Female veterans appear to suffer a steeper employment penalty than male veterans, but black veterans appear to suffer less of a penalty than white veterans. But on two other measures, earnings and college enrollment, veterans appear to be doing better than their civilian peers. Veterans with a high school education or less outearn their civilian peers, but veterans with at least some college education appear to lose some or all of the veteran earnings advantage compared to veterans with a high school degree, suggesting the greatest wage returns to military service accrue among the least educated. Veterans with at least a high school education are more likely to be enrolled in college than their civilian peers. Treating veterans as a monolithic block obscures differences in the consequences of military service across diverse groups. Copyright © 2013 Elsevier Inc. All rights reserved.

    2008-09-01

    In this paper we propose pricing bounds for European-style discrete arithmetic Asian basket options in a Black and Scholes framework. We start from methods used for basket options and Asian options. First, we use the general approach for deriving upper and lower bounds for stop-loss premia of sums of non-independent random variables as in Kaas et al. [Upper and lower bounds for sums of random variables, Insurance Math. Econom. 27 (2000) 151-168] or Dhaene et al. [The concept of comonotonicity in actuarial science and finance: theory, Insurance Math. Econom. 31(1) (2002) 3-33]. We generalize the methods in Deelstra et al. [Pricing of arithmetic basket options by conditioning, Insurance Math. Econom. 34 (2004) 55-57] and Vanmaele et al. [Bounds for the price of discrete sampled arithmetic Asian options, J. Comput. Appl. Math. 185(1) (2006) 51-90]. Afterwards we show how to derive an analytical closed-form expression for a lower bound in the non-comonotonic case. Finally, we derive upper bounds for Asian basket options by applying techniques as in Thompson [Fast narrow bounds on the value of Asian options, Working Paper, University of Cambridge, 1999] and Lord [Partially exact and bounded approximations for arithmetic Asian options, J. Comput. Finance 10 (2) (2006) 1-52]. Numerical results are included and on the basis of our numerical tests, we explain which method we recommend depending on moneyness and time-to-maturity.

    Full Text Available Total joint arthroplasty (TJA in a homeless patient is generally considered contraindicated. Here, we report our known medical and social (housing and employment results of homeless veterans who had TJA. Thirty-seven TJAs were performed on 33 homeless patients (31 men at our hospital between November 2000 and March 2014. This was 1.2% of all TJAs. Average age was 54 years. Average hospital stay was 4.1 days. There were no major inpatient complications. Thirty-four cases had at least 1-year follow-up in any clinic within the Veterans Affairs health care system. There were no known surgery-related reoperations or readmissions. At final follow-up, 24 patients had stable housing and 9 were employed. The extensive and coordinated medical and social services that were provided to veterans from the Department of Veterans Affairs contributed to our positive results.

  19. Hadron-nucleus bound states

    CERN Document Server

    Yamazaki, T

    2000-01-01

    A new type of nuclear spectroscopy to study hadron-nucleus bound states is described. The first successful experiment was to search for deeply bound pi sup - states in heavy nuclei using the sup 2 sup 0 sup 8 Pb(d, sup 3 He) reaction at GSI, in which a narrow peak arising from the 2p pi sup - orbital coupled with the neutron-hole states was observed at 135 MeV excitation energy. An improved experiment has just been carried out to separately identify the 1s and 2p pi sup - states. These experiments provide important information on the local potential strength, from which the effective mass of pi sup - is deduced to be 20 MeV. This method will be extended to search for eta and omega bound states as well as for K sup - bound states. The advantage of the bound-state spectroscopy versus invariant mass spectroscopy is emphasized.

  2. Faith-Based Organizations and Veteran Reintegration

    2015-01-01

    Abstract Faith-based organizations (FBOs) are an important community-based resource for veterans as they readjust to civilian life. Through interviews with both national-level and smaller, local FBOs, the authors sought to understand better the current and potential roles for FBOs in veteran reintegration. Interviewees suggested that veterans may look to FBOs for support because they offer privacy and confidentiality, two features that may be especially critical when a potential stigma is involved. Some FBOs have also developed a reputation as safe places for veterans, providing supportive, judgment-free environments. FBOs not only help veterans with spiritual matters but address diverse areas of veteran health and wellness, including vocation, education, financial and legal stability, shelter, access to goods and services, mental health, access to health care, physical health, family, and social networks. In some cases, the support is offered to veterans directly; in other instances, the support is indirect, via training individuals to help veterans or educating the public about them. In the process of providing support, FBOs interact with varied organizations, including government entities, private nonprofits, and one another, for training, outreach, referrals, information exchange, obtaining donations, and collaboration. Yet challenges exist, including insufficient connections with chaplains working in different settings and others in the web of support, resource and capacity constraints, lack of awareness of experience with veterans, issues related to religious philosophy or orientation, and characteristics of veterans themselves. To move forward, the authors offer recommendations for policymakers, organizations that interact with FBOs, and FBOs themselves to help FBOs engage fully in the web of reintegration support.

  3. Do homeless veterans have the same needs and outcomes as non-veterans?

    Tsai, Jack; Mares, Alvin S; Rosenheck, Robert A

    2012-01-01

    Although veterans have been found to be at increased risk for homelessness as compared to non-veterans, it is not clear whether those who are homeless have more severe health problems or poorer outcomes in community-based supported housing. This observational study compared 162 chronically homeless veterans to 388 non-veterans enrolled in a national-supported housing initiative over a 1-year period. Results showed that veterans tended to be older, were more likely to be in the Vietnam era age group, to be male, and were more likely to have completed high school than other chronically homeless adults. There were no differences between veterans and non-veterans on housing or clinical status at baseline or at follow-up, but both groups showed significant improvement over time. These findings suggest that the greater risk of homelessness among veterans does not translate into more severe problems or treatment outcomes. Supported housing programs are similarly effective for veterans and non-veterans.

    Women veterans represent a vulnerable population with unique health needs and disparities in access to care. One constellation of exposures related to subsequent poor health includes adverse childhood experiences (ACEs; e.g., physical and sexual child abuse), though research on impacts of ACEs among women veterans is limited. Data were drawn from the 2010 Behavioral Risk Factor Surveillance System for the 11 states that included the ACE module (n=36,485). Weighted chi-squared tests and multivariable logistic regression were used to assess the prevalence of ACEs among women veterans compared with women non-veterans and differences in the following outcomes, controlling for ACEs: social support, inadequate sleep, life satisfaction, mental distress, smoking, heavy alcohol use, obesity, diabetes, cardiovascular disease symptoms, asthma, and disability. Women veterans (1.6% of the total sample) reported a higher prevalence of 7 out of 11 childhood adversities and higher mean ACE score than women non-veterans. Women veterans were more likely to be current smokers and report a disability, associations which were attenuated when controlling for ACE. Despite women veterans' higher prevalence of ACE, their health outcomes did not differ substantially from non-veterans. Further research is needed to understand the intersections of traumatic experiences and sources of resilience over the lifecourse among women veterans.

  8. Differential impact of upward and downward comparisons on diverse women's disordered eating behaviors and body image.

    2016-05-01

    Etiological models of disordered eating are limited in their consideration of racial/ethnic differences in risk factors. Appearance comparisons are consistent predictors of disordered eating outcomes, but research predominantly examines these associations among White women and overlooks the potential differential impact of upward (comparing to someone perceived as better off) versus downward comparisons (comparing to someone perceived as worse off). This study investigated race/ethnicity as a moderator of the associations between upward and downward appearance comparisons and disordered eating outcomes and body satisfaction of young adult women. Measures of upward and downward appearance comparisons, body satisfaction, and disordered eating were administered to 1,014 young adult women. A multiple group (by race/ethnicity) path analysis was estimated using maximum likelihood estimation for each disordered eating and body satisfaction outcome, controlling for age and BMI. Upward comparisons were associated with higher levels of disordered eating behaviors and lower body satisfaction for women of all racial/ethnic groups. Downward appearance comparisons emerged as detrimental for Hispanic/Latina women, but were protective for Asian and White women. Findings challenge the belief that appearance comparisons impact all women similarly and that downward comparisons are universally protective, a position often promulgated by clinical treatment approaches. © 2015 Wiley Periodicals, Inc.

  11. Very accurate upward continuation to low heights in a test of non-Newtonian theory

    Science.gov (United States)

    Romaides, Anestis J.; Jekeli, Christopher

    1989-01-01

    Recently, gravity measurements were made on a tall, very stable television transmitting tower in order to detect a non-Newtonian gravitational force. This experiment required the upward continuation of gravity from the Earth's surface to points as high as only 600 m above ground. The upward continuation was based on a set of gravity anomalies in the vicinity of the tower whose data distribution exhibits essential circular symmetry and appropriate radial attenuation. Two methods were applied to perform the upward continuation - least-squares solution of a local harmonic expansion and least-squares collocation. Both methods yield comparable results, and have estimated accuracies on the order of 50 microGal or better (1 microGal = 10(exp -8) m/sq s). This order of accuracy is commensurate with the tower gravity measurments (which have an estimated accuracy of 20 microGal), and enabled a definitive detection of non-Newtonian gravity. As expected, such precise upward continuations require very dense data near the tower. Less expected was the requirement of data (though sparse) up to 220 km away from the tower (in the case that only an ellipsoidal reference gravity is applied).

  13. Upward appearance comparison and the development of eating pathology in college women.

    Science.gov (United States)

    Arigo, Danielle; Schumacher, Leah; Martin, Lindsay M

    2014-07-01

    Body dissatisfaction and disordered eating behaviors are common among college women, yet only a subset of this population develops clinically significant disordered eating symptoms during college. Appearance-based social comparisons, particularly those made to others with "better" bodies (i.e., upward appearance comparisons), have demonstrated concurrent relationships with body dissatisfaction and disordered eating. Little is known about the value of these comparisons for predicting the development of eating pathology, however. The present study examined the predictive value of upward appearance comparisons, as well as established risk factors (e.g., body dissatisfaction, negative affect), for the onset of clinically significant eating pathology over one college semester. College women (N = 454) completed validated self-report measures at the beginning of one semester, and again nine weeks later. Women who were newly above the clinical threshold for eating pathology at follow-up (n = 31) exhibited stronger baseline tendencies toward upward appearance comparisons than women who were below the threshold at both time points. In contrast, women who were already above the clinical threshold at baseline scored higher on established risk factors. These findings suggest that the extent of upward appearance comparison may be useful for identifying college women at particular risk for developing clinically significant disordered eating symptoms. © 2013 Wiley Periodicals, Inc.

  14. Do adaptive frequency response (AFR) hearing aids reduce 'upward spread' of masking?

    Science.gov (United States)

    Fabry, D A; Leek, M R; Walden, B E; Cord, M

    1993-01-01

    Speech recognition scores in noise are improved for some subjects who wear hearing aids that reduce low-frequency noise with an adjustable high-pass filter circuit. To evaluate whether these improvements were related to a reduction in upward spread of masking, pure-tone masking patterns for a low-frequency band-pass noise were measured in normal and hearing-impaired subjects. The filter skirt of the noise masker was very steep, with attenuation above the 1000 Hz cutoff greater than 120 dB per octave. Masking patterns for the same noise were also obtained in the presence of a high-pass filter that simulated the effects of an adaptive frequency response (AFR) hearing aid. Differences in the masking patterns were considered a measure of upward spread of masking. On average, subjects with high-frequency hearing loss demonstrated greater amounts of upward spread of masking than did normal-hearing listeners. Further, monosyllabic speech recognition in noise testing indicated improvements in performance of the hearing-impaired subjects related to the decrease of upward spread of masking in the high-pass filtering conditions.

    The upward leader is a key physical process of the leader progression model of lightning shielding. The inception mechanism and criterion of the upward leader need further understanding and clarification. Based on leader discharge theory, this paper proposes the critical electric field intensity of the stable upward leader (CEFISUL) and characterizes it by the valve electric field intensity on the conductor surface, E{sub L}, which is the basis of a new inception criterion for the upward leader. Through numerical simulation under various physical conditions, we verified that E{sub L} is mainly related to the conductor radius, and data fitting yields the mathematical expression of E{sub L}. We further establish a computational model for lightning shielding performance of the transmission lines based on the proposed CEFISUL criterion, which reproduces the shielding failure rate of typical UHV transmission lines. The model-based calculation results agree well with the statistical data from on-site operations, which show the effectiveness and validity of the CEFISUL criterion.

  17. UPWARD MOVEMENT OF PLUTONIUM TO SURFACE SEDIMENTS DURING AN 11-YEAR FIELD STUDY

    Energy Technology Data Exchange (ETDEWEB)

    Kaplan, D.; Beals, D.; Cadieux, J.; Halverson, J.

    2010-01-25

    An 11-y lysimeter study was established to monitor the movement of Pu through vadose zone sediments. Sediment Pu concentrations as a function of depth indicated that some Pu moved upward from the buried source material. Subsequent numerical modeling suggested that the upward movement was largely the result of invading grasses taking up the Pu and translocating it upward. The objective of this study was to determine if the Pu of surface sediments originated from atmosphere fallout or from the buried lysimeter source material (weapons-grade Pu), providing additional evidence that plants were involved in the upward migration of Pu. The {sup 240}Pu/{sup 239}Pu and {sup 242}Pu/{sup 239}Pu atomic fraction ratios of the lysimeter surface sediments, as determined by Thermal Ionization Mass Spectroscopy (TIMS), were 0.063 and 0.00045, respectively; consistent with the signatures of the weapons-grade Pu. Our numerical simulations indicate that because plants create a large water flux, small concentrations over multiple years may result in a measurable accumulation of Pu on the ground surface. These results may have implications on the conceptual model for calculating risk associated with long-term stewardship and monitored natural attenuation management of Pu contaminated subsurface and surface sediments.

    To prevent the occurrence of postoperative long lip, longitudinal postoperative changes in nasolabial forms of patients with unilateral cleft lip who underwent primary lip repair with or without upward advancement of the nasolabial components were compared. Forty-three subjects (24 unilateral cleft lip and palate [UCLP] and 19 unilateral cleft lip solely, and cleft lip and alveolus [UCL/UCLA]) who underwent primary lip repair with upward advancement of the nasolabial components (NA group) and 30 subjects (16 UCLP and 14 UCL/UCLA) without upward advancement (LA group) were enrolled. Postoperative photos taken at 1 and 6 months and at 1, 2, and 3 years were used for measuring the heights of the nasal alar base (NBH), the columellar base (CBH), Cupid's peak (CPH), and the upper lip (ULH). The ratios of these measurements between the affected and unaffected sides were calculated in both groups. In the LA group, the 3-year postoperative all-items ratios of UCLP were significantly larger than those at 1 month postoperatively, demonstrating drooping of the nasolabial tissues in the affected side (all P < .01). Furthermore, the 3-year postoperative CPH and ULH ratio of UCL/UCLA was significantly larger than that at 1 month postoperatively, demonstrating the long lip (P < .01). In the NA group, the NBH, CBH, and CPH ratios of both UCLP and UCL/UCLA did not show significant differences between 1 month and 3 years postoperatively. Upward advancement of the nasolabial components prevents postoperative long lip.

    The alpine treeline is commonly regarded as being sensitive to climatic warming because regeneration and growth of trees at treeline generally are limited by low temperature. The alpine treelines of the Tibetan Plateau (TP) occur at the highest elevations (4,900 m above sea level) in the Northern Hemisphere. Ongoing climatic warming is expected to shift treelines upward. Studies of treeline dynamics at regional and local scales, however, have yielded conflicting results, indicating either unchanging treeline elevations or upward shifts. To reconcile this conflict, we reconstructed in detail a century of treeline structure and tree recruitment at sites along a climatic gradient of 4 °C and mean annual rainfall of 650 mm on the eastern TP. Species interactions interacted with effects of warming on treeline and could outweigh them. Densification of shrubs just above treeline inhibited tree establishment, and slowed upward movement of treelines on a time scale of decades. Interspecific interactions are major processes controlling treeline dynamics that may account for the absence of an upward shift at some TP treelines despite continued climatic warming.

    Self-compassion may protect individuals experiencing poor body image and associated maladaptive outcomes. The purpose of the study was to examine within-person associations (whilst controlling for between-person differences) between appearance-related self-compassion, appearance-related threats (operationalised as upward appearance comparisons), and body image-related variables, namely, social physique anxiety, drive for thinness, and body dissatisfaction. A diary methodology was used whereby young women (n = 126; Mage = 21.26) responded to brief online surveys three times per day (11am, 3pm, and 7pm) every second day for one week (i.e. a total of 12 measurement points). Results of mixed linear modeling revealed that both state appearance-related upward comparisons and self-compassion independently predicted all three outcomes in a positive and negative fashion, respectively. No significant interaction effects between state appearance-related upward comparisons and self-compassion were found. The results suggested that appearance-based self-compassion was important, not just when there was a potential threat to body image via upward appearance comparisons. The findings highlight the importance of fostering self-compassion on a daily level. © 2017 The International Association of Applied Psychology.

  3. Sources of biogenic methane to form marine gas hydrates: In situ production or upward migration?

    Energy Technology Data Exchange (ETDEWEB)

    Paull, C.K.; Ussler, W. III; Borowski, W.S.

    1993-09-01

    Potential sources of biogenic methane in the Carolina Continental Rise -- Blake Ridge sediments have been examined. Two models were used to estimate the potential for biogenic methane production: (1) construction of sedimentary organic carbon budgets, and (2) depth extrapolation of modern microbial production rates. While closed-system estimates predict some gas hydrate formation, it is unlikely that >3% of the sediment volume could be filled by hydrate from methane produced in situ. Formation of greater amounts requires migration of methane from the underlying continental rise sediment prism. Methane may be recycled from below the base of the gas hydrate stability zone by gas hydrate decomposition, upward migration of the methane gas, and recrystallization of gas hydrate within the overlying stability zone. Methane bubbles may also form in the sediment column below the depth of gas hydrate stability because the methane saturation concentration of the pore fluids decreases with increasing depth. Upward migration of methane bubbles from these deeper sediments can add methane to the hydrate stability zone. From these models it appears that recycling and upward migration of methane is essential in forming significant gas hydrate concentrations. In addition, the depth distribution profiles of methane hydrate will differ if the majority of the methane has migrated upward rather than having been produced in situ.

    Full Text Available We give an explicit algorithm and source code for combining alpha streams via bounded regression. In practical applications, typically, there is insufficient history to compute a sample covariance matrix (SCM for a large number of alphas. To compute alpha allocation weights, one then resorts to (weighted regression over SCM principal components. Regression often produces alpha weights with insufficient diversification and/or skewed distribution against, e.g., turnover. This can be rectified by imposing bounds on alpha weights within the regression procedure. Bounded regression can also be applied to stock and other asset portfolio construction. We discuss illustrative examples.

  6. Risk Factors for Homelessness Among US Veterans

    2015-01-01

    Homelessness among US veterans has been a focus of research for over 3 decades. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this is the first systematic review to summarize research on risk factors for homelessness among US veterans and to evaluate the evidence for these risk factors. Thirty-one studies published from 1987 to 2014 were divided into 3 categories: more rigorous studies, less rigorous studies, and studies comparing homeless veterans with homeless nonveterans. The strongest and most consistent risk factors were substance use disorders and mental illness, followed by low income and other income-related factors. There was some evidence that social isolation, adverse childhood experiences, and past incarceration were also important risk factors. Veterans, especially those who served since the advent of the all-volunteer force, were at greater risk for homelessness than other adults. Homeless veterans were generally older, better educated, and more likely to be male, married/have been married, and to have health insurance coverage than other homeless adults. More studies simultaneously addressing premilitary, military, and postmilitary risk factors for veteran homelessness are needed. This review identifies substance use disorders, mental illness, and low income as targets for policies and programs in efforts to end homelessness among veterans. PMID:25595171

  7. Depression and dementias among military veterans.

    2014-06-01

    Depression is very common throughout the course of veterans' lives, and dementia is common in late life. Previous studies suggest an association between depression and dementia in military veterans. The most likely biologic mechanisms that may link depression and dementia among military veterans include vascular disease, changes in glucocorticoid steroids and hippocampal atrophy, deposition of β-amyloid plaques, inflammatory changes, and alterations of nerve growth factors. In addition, military veterans often have depression comorbid with posttraumatic stress disorder or traumatic brain injury. Therefore, in military veterans, these hypothesized biologic pathways going from depression to dementia are more than likely influenced by trauma-related processes. Treatment strategies for depression, posttraumatic stress disorder, or traumatic brain injury could alter these pathways and as a result decrease the risk for dementia. Given the projected increase of dementia, as well as the projected increase in the older segment of the veteran population, in the future, it is critically important that we understand whether treatment for depression alone or combined with other regimens improves cognition. In this review, we summarize the principal mechanisms of this relationship and discuss treatment implications in military veterans. Copyright © 2014 The Alzheimer's Association. All rights reserved.

    This study investigates an abnormal artificially triggered lightning event that produced two positive upward propagations: one during the initial stage (i.e., the upward leader (UL)) and the other after a negative downward aborted leader (DAL). The triggered lightning was induced in a weak thunderstorm over the experiment site and did not produce a return stroke. All of the intra-cloud lightning around the experiment site produced positive changes in the electric field. The initial stage was a weak discharge process. A downward dart leader propagated along the channel produced by the first UL, ending at a height of approximately 453 m and forming a DAL. Under the influence of the DAL, the electric field at a point located 78 m from the rod experienced a steady reduction of about 6.8 kV m-1 over 5.24 ms prior to the initiation of a new upward channel (i.e., the second upward propagation (UP)). The second UP, which started approximately 4.1 ms after the termination of the DAL and propagated along the original channel, was triggered by the DAL and sustained for approximately 2.95 ms. Two distinct current pulses were superimposed on the current of the second UP. The first pulse, which was related to the sudden initiation of the second UP, was characterized by a more rapid increase and decrease and a larger peak value than the second pulse, which was related to the development of the second UP into the area affected by the DAL. The second UP contained both a similar-to-leader process and a following neutralization process. This study introduces a new type of triggering leader, in which a new upward discharge is triggered in an established channel by an aborted leader propagating along the same channel with opposite polarity and propagation direction.

  10. Variation in Veteran Identity as a Factor in Veteran-Targeted Interventions.

    Science.gov (United States)

    Hack, Samantha M; DeForge, Bruce R; Lucksted, Alicia

    2017-07-01

    The sociocultural identities that people self-assign or accept influence their interpersonal interactions and decision making. Identity-based interventions attempt to influence individuals by associating healthy behaviors with in-group membership. Outreach and educational efforts aimed at veterans may rely on "typical" veteran identity stereotypes. However, as discussed in this Open Forum, there is evidence that veteran identity is not monolithic but rather fluctuates on the basis of personal characteristics and individual military service experiences. Overall, the impact of veteran identity on veterans' health behaviors and use of health care is not known and has been understudied. A major limiting factor is the lack of a standardized measure of veteran identity that can assess variations in salience, prominence, and emotional valence.

    This study examined the relative influences of PTSD, other psychopathology, and intimate partner alcohol and drug use on substance-related problems in U.S. veterans (242 couples, N = 484). Hierarchical regression analyses revealed that partner alcohol and drug use severity explained more variance in veteran alcohol use and drug use (20% and 13%, respectively) than did veteran PTSD, adult antisocial behavior, or depression symptoms combined (6% for veteran alcohol use; 7% for veteran drug use). Findings shed new light on the influence of relationship factors on veteran alcohol and drug use and underscore the importance of couples-oriented approaches to treating veterans with comorbid PTSD and substance abuse.

    Prevalences of Diagnostic Interview Schedule/DSM-III psychiatric disorders for male veterans and nonveterans from four war eras were estimated using data from over 7500 male community respondents interviewed by the Epidemiologic Catchment Area program at five geographic areas across the country. Veterans serving after Vietnam (Post-Vietnam era) had greater lifetime and 6-month prevalences of psychiatric disorder than their nonveteran counterparts, whereas the reverse tended to be the case for the Vietnam, Korean, and World War II war eras. Comparisons across war eras revealed a trend for more psychiatric disorder, especially substance abuse, in younger veterans and nonveterans than in older respondents.

    Differences in the characteristics and mental health needs of veterans of the Iraq/Afghanistan war when compared with those of veterans who served in the Persian Gulf war and in the Vietnam war may have important implications for Veterans Affairs (VA) program and treatment planning. Subjects were drawn from administrative data bases of veterans who sought treatment from specialized VA programs for treatment of posttraumatic stress disorder (PTSD). Current Iraq/Afghanistan veterans were compared with 4 samples of outpatient and inpatient Persian Gulf and Vietnam veterans whose admission to treatment was either contemporaneous or noncontemporaneous with their admission. A series of analyses of covariance was used hierachically to control for program site and age. In analyses of contemporaneous veterans uncontrolled for age, Iraq/Afghanistan veterans differed most notably from Vietnam veterans by being younger, more likely to be female, less likely to be either married or separated/divorced, more often working, less likely to have ever been incarcerated, and less likely to report exposure to atrocities in the military. Regarding clinical status, Iraq/Afghanistan veterans were less often diagnosed with substance abuse disorders, manifested more violent behavior, and had lower rates of VA disability compensation because of PTSD. Differences are more muted in comparisons with Persian Gulf veterans, particularly in those involving noncontemporaneous samples, or those that controlled for age differences. Among recent war veterans with PTSD, social functioning has largely been left intact. There is a window of opportunity, therefore, for developing and focusing on treatment interventions that emphasize the preservation of these social assets.

  1. Buoyancy effects on upward brine displacement caused by CO2 injection

    Energy Technology Data Exchange (ETDEWEB)

    Oldenburg, C.M.; Rinaldi, A.

    2010-01-15

    Upward displacement of brine from deep reservoirs driven by pressure increases resulting from CO{sub 2} injection for geologic carbon sequestration may occur through improperly sealed abandoned wells, through permeable faults, or through permeable channels between pinch-outs of shale formations. The concern about upward brine flow is that, upon intrusion into aquifers containing groundwater resources, the brine may degrade groundwater. Because both salinity and temperature increase with depth in sedimentary basins, upward displacement of brine involves lifting fluid that is saline but also warm into shallower regions that contain fresher, cooler water. We have carried out dynamic simulations using TOUGH2/EOS7 of upward displacement of warm, salty water into cooler, fresher aquifers in a highly idealized two-dimensional model consisting of a vertical conduit (representing a well or permeable fault) connecting a deep and a shallow reservoir. Our simulations show that for small pressure increases and/or high-salinity-gradient cases, brine is pushed up the conduit to a new static steady-state equilibrium. On the other hand, if the pressure rise is large enough that brine is pushed up the conduit and into the overlying upper aquifer, flow may be sustained if the dense brine is allowed to spread laterally. In this scenario, dense brine only contacts the lower-most region of the upper aquifer. In a hypothetical case in which strong cooling of the dense brine occurs in the upper reservoir, the brine becomes sufficiently dense that it flows back down into the deeper reservoir from where it came. The brine then heats again in the lower aquifer and moves back up the conduit to repeat the cycle. Parameter studies delineate steady-state (static) and oscillatory solutions and reveal the character and period of oscillatory solutions. Such oscillatory solutions are mostly a curiosity rather than an expected natural phenomenon because in nature the geothermal gradient prevents the

    Full Text Available This new generation of veterans is coming home to families, friends, employers, and communities that likely do not understand military culture, nor the effects that military service and reintegration have on a veteran’s life, leading to the next war – the Reintegration War. Military servicemembers, veterans, and their families face challenges within the Reintegration War that are different from their civilian counterparts and are complicated by military-specific circumstances. In order to more effectively and efficiently address the challenges servicemembers, veterans, and their families face, we need to work together in a comprehensive effort. Strategies are presented to help win the Reintegration War and ease the transition for servicemembers, veterans, and their families.

  8. Degradation of electrowetting for upward and downward electrolyte droplets containing microparticles

    Lee, Jung-Hoon; Song, Jang-Kun

    2014-02-01

    Electrowetting (EW) of an electrolyte droplet containing zinc or silica particles was investigated for durability and degradation of devices. Two types of experimental geometries exist, an upward droplet standing on a substrate and a downward droplet hanging under a substrate. Different gravitational effects of droplets for the two geometries shift the contact angle of the EW dynamics. Added zinc and silica particles significantly accelerated the degradation in the EW switching with increased driving time, which may result from the surface damage due to the collision between the particles and surface. The degradation was significantly influenced by many factors such as the particle dispersity, droplet direction, particle concentration, and viscosity of dispersions. Interestingly, the device with a downward droplet degraded much less than that with the upward droplet. Our findings will be highly useful in designing durable microfluidic and EW devices.

  9. An isotopic model for basal freeze-on associated with subglacial upward flow of pore water

    Souchez, R.; Samyn, D.; Lorrain, R.; Pattyn, F.; Fitzsimons, S.

    2004-01-01

    Subglacial freezing in polar glaciers can have a significant dynamical effect. Recent studies have shown that freezing of pore water flowing upward through subglacial fine-grained sediments at the freezing interface and progression of this freezing front downward are responsible for fast ice flow stoppage in ice streams. The upward pore water flow leads to the formation of debris-bearing basal ice layers. A model for stable isotope composition, both in δD and δ18O, is developed for predicting the isotopic composition of the ice segregated by such a mechanism. The development of this isotopic model for water films present along the grains of the subglacial sediment predicts the absence of apparent fractionation for the ice formed. This prediction is tested against two East Antarctic outlet glaciers by studying the δD-δ18O relationships in the basal ice layers of these glaciers.

    Eddy covariance fluxes of formic acid, HCOOH, were measured over a boreal forest canopy in spring/summer 2014. The HCOOH fluxes were bidirectional but mostly upward during daytime, in contrast to studies elsewhere that reported mostly downward fluxes. Downward flux episodes were explained well by modeled dry deposition rates. The sum of net observed flux and modeled dry deposition yields an upward gross flux of HCOOH, which could not be quantitatively explained by literature estimates of direct vegetative soil emissions nor by efficient chemical production from other volatile organic compounds, suggesting missing or greatly underestimated HCOOH sources in the boreal ecosystem. We implemented a vegetative HCOOH source into the GEOS-Chem chemical transport model to match our derived gross flux and evaluated the updated model against airborne and spaceborne observations. Model biases in the boundary layer were substantially reduced based on this revised treatment, but biases in the free troposphere remain unexplained.

  11. Boiling heat transfer of refrigerant R-21 in upward flow in plate-fin heat exchanger

    Science.gov (United States)

    Kuznetsov, V. V.; Shamirzaev, A. S.

    2015-11-01

    The article presents the results of experimental investigation of boiling heat transfer of refrigerant R-21 in upward flow in a vertical plate-fin heat exchanger with transverse size of the channels that is smaller than the capillary constant. The heat transfer coefficients obtained in ranges of small mass velocities and low heat fluxes, which are typical of the industry, have been poorly studied yet. The characteristic patterns of the upward liquid-vapor flow in the heat exchanger channels and the regions of their existence are detected. The obtained data show a weak dependence of heat transfer coefficient on equilibrium vapor quality, mass flow rate, and heat flux density and do not correspond to calculations by the known heat transfer models. A possible reason for this behavior is a decisive influence of evaporation of thin liquid films on the heat transfer at low heat flux.

    2016-01-01

    Airborne gravimetry has become a vital technique in local gravity field approximation, and upward/downward continuation of gravity data is a key process of airborne gravimetry. In these procedures, the integral domain is divided into two parts, namely the near-zone and the far-zone. The far-zone contributions are approximated by the truncation coefficients and a global geo-potential model, and their values are controlled by several issues. This paper investigates the effects of flight height,...

    A lightning strike to the center of three 78-m radio transmission towers produced upward discharges with lengths of 40 and 79 m from each of the neighboring towers. This strike also caused a number of insulators on guy wires that supported the tower to flash over, and the locations of these points and the two-dimensional geometry of the discharge channels are projected onto a vertical plane that is centered on the tower.

  16. Species interactions slow warming-induced upward shifts of treelines on the Tibetan Plateau

    OpenAIRE

    Liang, Eryuan

    2016-01-01

    The alpine treeline is commonly regarded as being sensitive to climatic warming because regeneration and growth of trees at treeline generally are limited by low temperature. The alpine treelines of the Tibetan Plateau (TP) occur at the highest elevations (4,900 m above sea level) in the Northern Hemisphere. Ongoing climatic warming is expected to shift treelines upward. Studies of treeline dynamics at regional and local scales, however, have yielded conflicting results, indicating either unc...

    Beam-column joint (BCJ) of reinforced concrete is an area of critical which must be carefully designed to absorb the seismic energy. Inability to absorb seismic energy will cause serious damage to structural failure. It will lead to shear failure, i.e. brittle and endanger users of the building if the BCJ area is not designed properly. In order to get a building structure is safe and resistant to disasters, mainly due to the earthquake, the structure must be designed in accordance to the rules of standard construction (eligible detailing). In general, the anchorages (detailing) reinforcement beams to the column is pointing downwards, however, what if the steel anchoring beams are pointing upwards. Different anchoring will result in the behavior of different structures, such as fracturing pattern. This study observes two anchoring model, by making two test specimens of BCJ. One set of reinforcement beams anchored BCJ upward and downward respectively, which are applied with monotonic static load. The study investigated the pattern of cracks and ductility of the beam displacement on BCJ. The results showed that the downward anchoring in the fracturing pattern out of the area BCJ was anchoring upward pattern rift goes deep into the area BCJ, thus anchoring above makes BCJ unsafe. Downward anchoring are more ductile than the upward anchoring, however the deflection of all BJC specimens was higher than the boundaries maximum deflection prediction (Δprediction = 10.45 mm < eksp Δexp-min = 13.15 mm), which can be assumed that all BCJ specimens were ductile, but it still in ductile limited due to displacement ductility μΔ<3,5.

    Airborne Lidar (Light detection and ranging) is an efficient tool for the generation of Digital Terrain Models (DTMs). Although many studies have been conducted in generating DTMs using Lidar data, it is still a challenging research area. The difficulty in filtering large buildings as well as a diversity of urban features makes the design of urban DTM generating methods an ongoing priority. This research adopted an upward-fusion methodology to generate urban DTMs using airborne Lidar data. Firstly, several preliminary DTMs of different resolutions were obtained using a local minimum method. Next, upward fusion was conducted between these DTMs. This process began with the DTM of the largest grid size, which was treated as a trend surface. A finer DTM was compared with this large scale DTM. By setting appropriate thresholds, a new DTM was achieved by selecting qualified elevation values from the finer DTM and retaining the value of the trend surface when the value from the finer DTM was beyond the threshold. This process continued iteratively until all preliminary DTMs had been included in the upward fusion and a refined DTM of high resolution was achieved. To further reduce possible errors in the resulting DTM, an extended local minimum method was proposed for filtering outliers and generating preliminary DTMs. A case study was carried out in the city of Cambridge, which represents an urban landscape with a variety of building forms, street patterns and vegetation structures. The time efficiency, results of the accuracy assessments and comparison with leading software proved the success of the case study and indicated that upward-fusion was an effective method for the generation of urban DTMs with airborne Lidar data and could improve the accuracy of other DTM generating algorithms. This paper also proposed possible approaches for further improvements on this methodology.

    Coronal magnetic flux ropes are closely related to large-scale solar activities. Using a 2.5-dimensional time-dependent ideal magnetohydrodynamic model in Cartesian coordinates, we carry out numerical simulations to investigate the evolution of a magnetic system consisting of a flux rope embedded in a fully closed quadrupolar magnetic field with different photospheric flux distributions. It is found that when the photospheric flux is not concentrated too much toward the polarity inversion line and the constraint exerted by the background field is not too weak, the equilibrium states of the system are divided into two branches: the rope sticks to the photosphere for the lower branch and levitates in the corona for the upper branch. These two branches are connected by an upward catastrophe (from the lower branch to the upper) and a downward catastrophe (from the upper branch to the lower). Our simulations reveal that there exist both upward and downward catastrophes in quadrupolar fields, which may be either force-free or non-force-free. The existence and the properties of these two catastrophes are influenced by the photospheric flux distribution, and a downward catastrophe is always paired with an upward catastrophe. Comparing the decay indices in catastrophic and noncatastrophic cases, we infer that torus unstable may be a necessary but not sufficient condition for a catastrophic system.

    Treeline responses to environmental changes describe an important phenomenon in global change research. Often conflicting results and generally too short observations are, however, still challenging our understanding of climate-induced treeline dynamics. Here, we use a state-of-the-art dendroecological approach to reconstruct long-term changes in the position of the alpine treeline in relation to air temperature at two sides in the Changbai Mountains in northeast China. Over the past 160 years, the treeline increased by around 80 m, a process that can be divided into three phases of different rates and drives. The first phase was mainly influenced by vegetation recovery after an eruption of the Tianchi volcano in 1702. The slowly upward shift in the second phase was consistent with the slowly increasing temperature. The last phase coincided with rapid warming since 1985, and shows with 33 m per 1°C, the most intense upward shift. The spatial distribution and age structure of trees beyond the current treeline confirm the latest, warming-induced upward shift. Our results suggest that the alpine treeline will continue to rise, and that the alpine tundra may disappear if temperatures will increase further. This study not only enhances mechanistic understanding of long-term treeline dynamics, but also highlights the effects of rising temperatures on high-elevation vegetation dynamics. © 2017 John Wiley & Sons Ltd.

    Climate change is expected to trigger an upward expansion of plants in mountain regions and, although there is strong evidence that many native species have already shifted their distributions to higher elevations, little is known regarding how fast non-native species might respond to climate change. By analysing 131,394 occurrence records of 1,334 plant species collected over 20 years in the European Alps, we found that non-natives are spreading upwards approximately twice as fast as natives. Whereas the spread of natives was enhanced by traits favouring longer dispersal distances, this was not the case for non-natives. This was due to the non-native species pool already being strongly biased towards species that had traits facilitating spread. A large proportion of native and non-native species seemed to be able to spread upwards faster than the current velocity of climate change. In particular, long-distance dispersal events and proximity to roads proved to be key drivers for the observed rapid spread. Our findings highlight that invasions by non-native species into native alpine communities are a potentially significant additional pressure on these vulnerable ecosystems that are already likely to suffer dramatic vegetation changes with ongoing warming and increasing human activity in mountain regions.

  2. Neutrino-induced upward-going muons in Super-Kamiokande

    CERN Document Server

    Habig, A

    1999-01-01

    Upward-going muons observed by the Super-Kamiokande detector are produced by high-energy atmospheric neutrinos which interact in rock around the detector. Those which pass completely through the detector have a mean parent neutrino energy of ~100 GeV, while those which range out inside the detector come from neutrinos of mean energy ~10 GeV. The neutrino baseline varies with the observed muon zenith angle, allowing for an independent test via nu-mu disappearance of the neutrino oscillations observed in the Super-Kamiokande contained events. 614 upward through-going and 137 upward stopping muons were observed over 537 (516) live days, resulting in a flux of Phi_t=1.74\\pm0.07(stat.)\\pm0.02(sys.), Phi_s=0.380\\pm0.038(stat.)^{+0.019}_{-0.016}(sys.) x10^{-13}cm^{-2}s^{-1}sr^{-1}. The observed stopping/through-going ratio R=0.218\\pm0.023(stat.)^{+0.014}_{-0.013}(syst.) is 2.9 sigma lower than the expectation of 0.368^{+0.049}_{-0.044}(theo.).

    Full Text Available Abnormal scapulothoracic mechanics and scapulohumeral rhythm are implicated in shoulder pathologies, including glenohumeral impingement and rotator cuff tears. Upward scapula rotation, specifically asymmetry of scapula motion and associations of patterns through range with injury, was investigated in dominant and non-dominant limbs of nationally ranked junior and Paralympic swimmers during competition season. The static and throughout phases measures of upward scapula rotation were: Phase I (start position, 45°, Phase II (45° to 90°, Phase III (90° to 135° and Phase IV (135° to max. Injury was assessed with a validated questionnaire. Differences between side (dominant and non-dominant, group (junior and Paralympic, and phase were examined. Significant differences (P < 0.05 between groups were identified for dominant side at rest, 45° and 135°, and in phases II and IV (including range. Scapulohumeral rhythm was higher in the non-dominant limb of Paralympic swimmers but in the dominant limb of junior swimmers. Greatest differences in upward rotation between injured and non-injured swimmers were found in Phase 1: 43.6% (3.3° Paralympic; 73.1% (8° junior. Results suggest asymmetry of movement in both limbs, through all phases, and at single points in range, should be investigated for assessing injury and developing preventive strategies and rehabilitation protocols.

    2017-02-01

    Authors comparatively analyzed health and social isolation between U.S. military veterans denied Veterans Affairs (VA) disability compensation and veterans awarded VA disability compensation. The 2001 National Survey of Veterans was used to create a sample of 4,522 veterans denied or awarded VA disability compensation. Using the Andersen health services utilization model as a conceptual framework, multivariate logistic regression was applied to assess relationships between VA disability compensation award status, three separate domains of health, and correlates of social isolation. Results indicate that denied applicants were more likely than those awarded to have poor overall health (odds ratio [OR] = 1.45, 95% confidence interval [CI]: 1.23, 1.70), and limitations in activities of daily living (OR = 1.12, 95% CI: 1.03, 1.21). Denied applicants' physical functioning (40.3) and mental functioning (41.2) composite summary scores were not clinically different from those of awarded applicants (39.0 and 40.1, respectively), indicating that both were comparably impaired. Veterans denied VA disability compensation had poor health and functional impairments. They also experienced poverty and isolation, suggesting that they may be in need of additional supportive services. Connecting veterans to community resources could be a vital service to provide to all veterans applying for disability compensation. © 2016 National Association of Social Workers.

    In an effort to assess and reduce gender-related quality gaps, the Veterans Health Administration (VHA) has promoted gender-based research. Historically, such appraisals have often relied on secondary databases, with little attention to methodological implications of the fact that VHA provides care to some nonveteran patients. To determine whether conclusions about gender differences in utilization and cost of VHA care change after accounting for veteran status. Cross-sectional. All users of VHA in 2002 (N = 4,429,414). Veteran status, outpatient/inpatient utilization and cost, from centralized 2002 administrative files. Nonveterans accounted for 50.7% of women (the majority employees) but only 3.0% of men. Among all users, outpatient and inpatient utilization and cost were far lower in women than in men, but in the veteran subgroup these differences decreased substantially or, in the case of use and cost of outpatient care, reversed. Utilization and cost were very low among women employees; women spouses of fully disabled veterans had utilization and costs similar to those of women veterans. By gender, nonveterans represent a higher proportion of women than of men in VHA, and some large nonveteran groups have low utilization and costs; therefore, conclusions about gender disparities change substantially when veteran status is taken into account. Researchers seeking to characterize gender disparities in VHA care should address this methodological issue, to minimize risk of underestimating health care needs of women veterans and other women eligible for primary care services.

    Failure of the scapulohumeral rhythm (SHR) is observed in patients with shoulder joint dysfunction. The SHR reportedly has a 2:1 ratio during scapular upward rotation with arm elevation. However, three-dimensional scapular motion analysis has indicated variations in this ratio according to the arm elevation angle. We observed 2 distinct patterns: the scapular upward rotation decreased after knot formation (type I) or increased after knot formation (type II) during arm elevation. In the present study, we aimed to identify the knot and investigate the influence of varying external loads on this kinesiological change point. We evaluated 35 healthy adult men (35 dominant-side shoulders) with a mean age of 20 ± 1.7 years (mean height: 172 ± 6.4 cm, mean weight: 65.7 ± 5.8 kg). Participants performed scapular plane elevation with no load or with an external load (1-5 kg) while sitting on a chair. The measured scapular upward rotation values were interpolated using the spline function and fitted to line graphs, and the change in these values was compared for various loads. The estimated knot angles (standard error) in the no load condition, and with external loads of 1, 2, 3, 4, and 5 kg were 83.5 (2.9°), 81.2 (2.9°), 81.0 (2.9°), 76.1 (2.9°), 73.4 (3.1°), and 75.8 (3.1°), respectively. No significant difference was noted in the knot position at 1-2 kg (vs. unloaded), although the knot was significantly lower at 3-5 kg (3 kg: p = 0.01, 4 kg: p = 0.001, and 5 kg: p = 0.02). Moreover, we observed that participants either exhibited increased or decreased upward rotational momentum after knot formation. Our results confirm that the kinesiological change point (the knot) during scapular upward rotation occurred at lower angles in cases of increasing external loads.

    Homeless women Veterans have a high prevalence of chronic mental and physical conditions that necessitate frequent healthcare visits, but travel burdens to specialty services may be overwhelming to navigate for this population, especially for those in rural settings. Access to specialty care is a key priority in the Veterans Health Administration (VHA) and understanding the geographic distribution and rural designation of this population in relation to medical centers (VAMC) can assist in care coordination. We identified 41,747 women Veterans age 18-44y with administrative evidence of homelessness in the VHA anytime during 2002-2015. We found 7% live in rural settings and 29% live >40miles from a VAMC. The mean travel distance for homeless women Veterans with a rural designation to a VAMC specialty center was 107 miles. Developing interventions to overcome this travel burden and engage vulnerable Veterans in necessary care can improve overall health outcomes for this high-risk population.

    Healthcare systems are interested in technology-enhanced interventions to improve patient access and outcomes. However, there is uncertainty about feasibility and acceptability for groups who may benefit but are at risk for disparities in technology use. Thus, we sought to describe characteristics of Internet use and technology-related attitudes for two such groups: (1) Veterans with multi-morbidity and high acute care utilization and (2) informal caregivers of Veterans with substantial care needs at home. We used survey data from two ongoing trials, for 423 Veteran and 169 caregiver participants, respectively. Questions examined Internet use in the past year, willingness to communicate via videoconferencing, and comfort with new technology devices. Most participants used Internet in the past year (81% of Veterans, 82% of caregivers); the majority of users (83% of Veterans, 92% of caregivers) accessed Internet at least a few times a week, and used a private laptop or computer (81% of Veterans, 89% of caregivers). Most were willing to use videoconferencing via private devices (77-83%). A majority of participants were comfortable attempting to use new devices with in-person assistance (80% of Veterans, 85% of caregivers), whereas lower proportions were comfortable "on your own" (58-59% for Veterans and caregivers). Internet use was associated with comfort with new technology devices (odds ratio 2.76, 95% confidence interval 1.70-4.53). Findings suggest that technology-enhanced healthcare interventions are feasible and acceptable for Veterans with multi-morbidity and high healthcare utilization, and informal caregivers of Veterans. In-person assistance may be important for those with no recent Internet use.

  12. Will Veterans Answer Sexual Orientation and Gender Identity Questions?

    The Veterans Health Administration does not routinely collect and document sexual orientation and gender identity (SOGI) data, despite existing health disparities among sexual and gender minority Veterans. Because of the legacy of previous Department of Defense (DoD) policies that prohibited disclosure of sexual or gender minority identities among active duty personnel, Veterans may be reluctant to respond to SOGI questions. This population-based study assesses item nonresponse to SOGI questions by Veteran status. This is a secondary analysis of data from a population-based sample of adults in 20 US states that elected to administer a SOGI module in the 2014 Behavioral Risk Factor Surveillance System survey. Prevalence of SOGI refusals and responses of "don't know" were compared for Veterans and non-Veterans. Veterans (n=22,587) and non-Veterans (n=146,475) were surveyed. Nearly all Veteran respondents (≥98%) completed the SOGI questions, with 95.4% identifying as heterosexual, 1.2% as gay or lesbian, 1.2% as bisexual, and 0.59% as transgender. A significantly lower proportion of Veterans than non-Veterans refuse to answer sexual orientation (1.5% vs. 1.9%). There was no difference between Veterans and non-Veterans in responses for gender identity. Veterans are just as likely as non-Veterans to complete SOGI items in survey research. Asking Veterans about SOGI is unlikely to yield significant nonresponse. These data suggest that future research should investigate Veterans' perspectives on being asked about SOGI in research settings and as part of routine clinical care.

    Social norms-based interventions have shown promise in reducing drinking behavior and the resulting consequences in young adults. Although most research has focused on young civilians (i.e., college students), some studies have investigated social norms-based interventions with active-duty military and veteran samples. Yet, research has not yet determined how to maximize the effectiveness of social norms-based interventions in this heavy-drinking population. As an initial step toward this goal, the current study utilized a community sample of 1,023 young adult veterans to examine (a) whether veteran perceptions of the drinking behavior of their veteran peers differ from their perceptions of civilian drinking behavior, (b) whether perceptions of specific veteran groups differ from the actual drinking behavior of veterans within those groups, (c) what levels of specificity in reference groups (same-gender civilians, same-branch veterans, same-gender veterans, or same-branch-and-gender veterans) are most strongly associated with veterans' own drinking, and (d) whether perceptions about others' attitudes toward drinking also contribute independently of perceived behavioral norms to veteran drinking. Findings indicated that participants perceived that other veterans drank more than civilians and that veteran groups drank more than veterans in the sample actually drank. Veteran-specific perceived behavioral norms were similar in their associations with drinking outcomes, whereas same-gender civilian perceived behavioral norms exhibited little or no associations with drinking. Veteran-specific perceived attitudinal norms exhibited little or no association with drinking behavior after controlling for perceived behavioral norms. These findings can be used to inform the development of social norms interventions for young adult veterans. (c) 2016 APA, all rights reserved).

  14. War veterans as peace builders

    Directory of Open Access Journals (Sweden)

    Kostić Novica

    2010-01-01

    Full Text Available In the period from 1991. to 1999. over 1500000 people in former Yugoslavia were members of dozens military formations that participated in the war in different manners and with various motives. These persons have actively contributed to the tragedy caused by war, that was and for some time will be the most important factor of social and personal relationships between individuals and the nations in the member states of former Yugoslavia. They are now left on their own and exposed to manipulation by nationalist centers and certain politicians. Because of their wartime past, they are usually depicted as the carriers of nationalistic and warmongering ideas on the 'other' side. However, viewed from the aspect of peace-building, ex-soldiers represent a significant potential, because many of them, in fact, have a need to contribute to building a more just society and feel responsible for what happened. In this paper it is discussed how some war veterans decided to join forces and contribute to the reconciliation in the former Yugoslavia by their joint activities.

    Social norms-based interventions have shown promise in reducing drinking behavior and resulting consequences in young adults. Although most research has focused on young civilians (i.e., college students), some studies have investigated social norms-based interventions with active duty military and veteran samples. Yet, research has not yet determined how to maximize the effectiveness of social norms-based intervention in this heavy drinking population. As an initial step toward this goal, the current study utilized a community sample of 1,023 young adult veterans to examine: (1) whether veteran perceptions of the drinking behavior of their veteran peers differ from their perceptions of civilian drinking behavior, (2) whether perceptions of specific veteran groups differ from actual drinking behavior of veterans within those groups, (3) what levels of specificity in reference groups (same-gender civilians, same-branch veterans, same-gender veterans, or same-branch-and-same-gender veterans) are most strongly associated with veterans’ own drinking, and (4) whether perceptions about others’ attitudes toward drinking also contribute independently of perceived behavioral norms to veteran drinking. Findings indicated that participants perceived that other veterans drank more than civilians and that veteran groups drank more than veterans in the sample actually drank. Veteran-specific perceived behavioral norms were similar in their associations with drinking outcomes, whereas same-gender civilian perceived behavioral norms exhibited little or no associations with drinking. Veteran-specific perceived attitudinal norms exhibited little or no association on drinking behavior after controlling for perceived behavioral norms. These findings can be used to inform the development of social norms interventions for young adult veterans. PMID:26415056

    The relationship between homelessness among veterans and mental illness and suicidality has not been clearly defined. To further examine this relationship, we compared rates of mental illness and suicidality among homeless and domiciled veterans seeking urgent psychiatric care at a US Department of Veterans Affairs (VA) facility. Information was collected by survey from 482 consecutive veterans seeking care at the Psychiatric Emergency Clinic (PEC) at the VA San Diego Healthcare System. A total of 73 homeless veterans were designated the homeless group and 73 domiciled veterans were randomly selected as the domiciled group. Suicidality and mental illnesses were assessed by self-assessment questionnaires and chart review of diagnoses. The homeless group had significantly higher rates of past suicide attempts (47% vs 27%) and recent reckless or self-harming behavior (33% vs 18%) compared with the domiciled group but significantly lower rates of depressive disorder (25% vs 44%), as diagnosed by a PEC physician. There were no differences between groups on the questionnaires for posttraumatic stress disorder (PTSD), depression, or alcohol abuse. Nor were there differences in diagnoses of bipolar disorder, PTSD, anxiety disorder, schizophrenia/schizoaffective disorder, or alcohol abuse. Veterans seeking help from a VA-based urgent psychiatric care clinic often are burdened by substantial depression, alcohol use disorders, PTSD, and both past and present suicide risk.

    To examine how dual coverage for nonelderly, low-income veterans by Veterans Affairs (VA) and Medicaid affects their demand for care. Veterans Affairs utilization data and Medicaid Analytic Extract Files. A retrospective, longitudinal study of VA users prior to and following enrollment in Medicaid 2006-2010. Veterans Affairs reliance, or proportion of care provided by VA, was estimated with beta-binomial models, adjusting for patient and state Medicaid program factors. In a cohort of 19,890 nonelderly veterans, VA utilization levels were similar before and after enrolling in Medicaid. VA outpatient reliance was 0.65, and VA inpatient reliance was 0.53 after Medicaid enrollment. Factors significantly associated with greater VA reliance included sociodemographic factors, having a service-connected disability, comorbidity, and higher state Medicaid reimbursement. Factors significantly associated with less VA reliance included months enrolled in Medicaid, managed care enrollment, Medicaid eligibility type, longer drive time to VA care, greater Medicaid eligibility generosity, and better Medicaid quality. Veterans Affairs utilization following new Medicaid enrollment remained relatively unchanged, and the VA continued to provide the large majority of care for dually enrolled veterans. There was variation among patients as Medicaid eligibility and other program factors influenced their use of Medicaid services. © Health Research and Educational Trust.

    To quantify fixation stability of the upward gaze in patients with myasthenia gravis (MG) using an eye tracker. In this study, 21 normal subjects, 5 patients with MG with diplopia, 5 patients with MG without diplopia and 6 patients with superior oblique (SO) palsy were included. Subjects fixated on a target in the upward direction for 1 min. The horizontal (X) and vertical (Y) eye positions were recorded using an eye tracker. Fixation stability was first quantified using the bivariate contour ellipse areas (BCEA) of fixation points as an index of whole stability. Then, the SDs of the X and Y eye positions (SDX and SDY, respectively) were quantified as indices of directional stability, with the data divided into three 20 s fractions to detect temporal fixation fluctuation. BCEAs were larger in patients with MG (both with and without diplopia) than normal subjects and patients with SO palsy, without significant differences among the three 20 s fractions. Compared with normal subjects, SDXs were larger only in patients with MG with diplopia; SDYs were larger in both patients with MG with and without diplopia. In addition, SDYs in patients with MG with diplopia were larger than those in patients with MG without diplopia and patients with SO palsy. Furthermore, a significant difference among the three 20 s fractions was detected for SDYs in patients with MG with diplopia. Patients with MG, especially those with diplopia, exhibit fixation instability in the upward gaze. Non-invasive quantification of fixation stability with an eye tracker is useful for precisely identifying MG-specific fatigue characteristics. UMIN000023468; pre-results.

    Phosphorus-32 was supplied to the roots of stem-ringed 1-year-old apple trees and 2-year-old citrus trees on which bark segments were isolated above and below the ring. /sup 32/P was translocated to shoots and leaves although considerable translocation occurred especially in wood and bark tissues. The accumulation of /sup 32/P in isolated bark segments indicated that the occurrence of these materials in this tissue was via radial translocation from xylem tissue, and that the main upward translocation pathway of /sup 32/P supplied to roots is through the xylem.

    CSF flux is involved in the pathophysiology of neurodegenerative diseases and cognitive impairment after traumatic brain injury, all hallmarked by the accumulation of cellular metabolic waste. Its effective disposal via various CSF routes has been demonstrated in animal models. In contrast, the CSF dynamics in humans are still poorly understood. Using novel real-time MRI, forced inspiration has been identified recently as a main driving force of CSF flow in the human brain. Exploiting technical advances toward real-time phase-contrast MRI, the current work analyzed directions, velocities, and volumes of human CSF flow within the brain aqueduct as part of the internal ventricular system and in the spinal canal during respiratory cycles. A consistent upward CSF movement toward the brain in response to forced inspiration was seen in all subjects at the aqueduct, in 11/12 subjects at thoracic level 2, and in 4/12 subjects at thoracic level 5. Concomitant analyses of CSF dynamics and cerebral venous blood flow, that is, in epidural veins at cervical level 3, uniquely demonstrated CSF and venous flow to be closely communicating cerebral fluid systems in which inspiration-induced downward flow of venous blood due to reduced intrathoracic pressure is counterbalanced by an upward movement of CSF. The results extend our understanding of human CSF flux and open important clinical implications, including concepts for drug delivery and new classifications and therapeutic options for various forms of hydrocephalus and idiopathic intracranial hypertension. SIGNIFICANCE STATEMENT Effective disposal of brain cellular waste products via CSF has been demonstrated repeatedly in animal models. However, CSF dynamics in humans are still poorly understood. A novel quantitative real-time MRI technique yielded in vivo CSF flow directions, velocities, and volumes in the human brain and upper spinal canal. CSF moved upward toward the head in response to forced inspiration. Concomitant

  15. Comparing life experiences in active addiction and recovery between veterans and non-veterans: a national study.

    The costs of addiction are well documented, but the potential benefits of recovery are less well known. Similarly, substance use issues among both active duty military personnel and veterans are well known but their recovery experiences remain underinvestigated. Furthermore, little is known about whether and how addiction and recovery experiences differ between veterans and non-veterans. This knowledge can help refine treatment and recovery support services. Capitalizing on a national study of individuals in recovery (N = 3,208), we compare addiction and recovery experiences among veterans (n = 481) and non-veterans. Veterans' addiction phase was 4 years longer than non-veterans and they experienced significantly more financial and legal problems. Dramatic improvements in functioning were observed across the board in recovery with subgroup differences leveling off. We discuss possible strategies to address the specific areas where veterans are most impaired in addiction and note study limitations including the cross-sectional design.

    2017-06-01

    Full Text Available Veterans comprise a unique culture. Through their military experience, Veterans become ingrained with shared values, beliefs and attitudes that characterize their everyday existence. Health care providers must take into consideration that culture impacts health care seeking behaviors. The theory of Caring with Honor is emerging through the classic GT method. A team of investigators within the VA health care system gathered data from 19 health care professionals via one-on-one interviews. The emerging theory, Caring with Honor, represents an amplifying process whereby health care professionals engage with Veterans through a process of enculturating, witnessing, connecting, honoring, and caring with purpose.

  8. Three Generations, Three Wars: African American Veterans.

    Science.gov (United States)

    Black, Helen K

    2016-02-01

    This article emerged from pilot research exploring experiences of war and suffering among African American veterans who served in World War II, Korean War, and Vietnam War. Men's experiences as soldiers reflected both racism and the social change that occurred in the Unites States while they served. We used techniques of narrative elicitation, conducting qualitative, ethnographic interviews with each of five veterans in his home. Interviews focused on unique and shared experiences as an African American man and a soldier. Three important themes emerged: (a) Expectations related to War--Although men viewed service to country as an expected part of life, they also expected equal treatment in war, which did not occur; (b) Suffering as an African American--Informants interpreted experiences of suffering in war as related to the lower status of African American servicemen; and (c) Perception of present identity--Each man was honed by the sum of his experiences, including those of combat, racism, and postwar opportunities and obstacles. From 40 to 70 years after the wars were fought, there are few scholarly narrative studies on African American veterans, despite the fact that Korean War Veterans are entering old-old age and few World War II Veterans are alive. The value of pilot research that offers narratives of unheard voices is significant; larger studies can interview more African American veterans to advance knowledge that might soon be lost. © The Author 2015.

    This is a paper about private data analysis, in which a trusted curator holding a confidential database responds to real vector-valued queries. A common approach to ensuring privacy for the database elements is to add appropriately generated random noise to the answers, releasing only these {\\em noisy} responses. In this paper, we investigate various lower bounds on the noise required to maintain different kind of privacy guarantees.

    We propose a simple and straightforward method based on Wronskians for the calculation of bound-state energies and wavefunctions of one-dimensional quantum-mechanical problems. We explicitly discuss the asymptotic behaviour of the wavefunction and show that the allowed energies make the divergent part vanish. As illustrative examples we consider an exactly solvable model, the Gaussian potential well, and a two-well potential proposed earlier for the interpretation of the infrared spectrum of ammonia.

  13. History of guide dog use by veterans.

    Ostermeier, Mark

    2010-08-01

    The first guide dog school was established in Germany during World War I to care for German soldiers blinded in that war. Other schools in Germany followed. Observation by an American at one of the schools led to the creation of the first guide dog school in the United States in 1929, "The Seeing Eye." Additional U.S. schools were opened during and after World War II. This article discusses the history of guide dog use by veterans, including the formation of the first guide dog schools in response to aiding blinded servicemen, and the involvement of federal agencies and guide dog schools in providing assistance to blinded veterans.

  14. Cyclotron transitions of bound ions

    Bezchastnov, Victor G.; Pavlov, George G.

    2017-06-01

    A charged particle in a magnetic field possesses discrete energy levels associated with particle rotation around the field lines. The radiative transitions between these levels are the well-known cyclotron transitions. We show that a bound complex of particles with a nonzero net charge displays analogous transitions between the states of confined motion of the entire complex in the field. The latter bound-ion cyclotron transitions are affected by a coupling between the collective and internal motions of the complex and, as a result, differ from the transitions of a "reference" bare ion with the same mass and charge. We analyze the cyclotron transitions for complex ions by including the coupling within a rigorous quantum approach. Particular attention is paid to comparison of the transition energies and oscillator strengths to those of the bare ion. Selection rules based on integrals of collective motion are derived for the bound-ion cyclotron transitions analytically, and the perturbation and coupled-channel approaches are developed to study the transitions quantitatively. Representative examples are considered and discussed for positive and negative atomic and cluster ions.

  15. Measured current and close electric field changes associated with the initiation of upward lightning from a tall tower

    2012-04-01

    We examine in detail the simultaneous lightning current waveforms, close electric field changes, and lightning location system data for upward lightning discharges initiated from the Gaisberg Tower (GBT) from 2005 to 2009. Out of 205 upward flashes, most of them (87% or 179/205) were initiated from the tower top without any nearby preceding lightning activity (called "self-initiated"), whereas 26 upward flashes (13%) were initiated from the tower top with immediately preceding nearby lightning activity (called "nearby-lightning-triggered"), including 15 positive ground flashes, one negative ground flashes, and 10 cloud discharges. The possible reasons for self-initiated upward flashes dominating at the GBT could be the field enhancement due to the Gaisberg Mountain above the surrounding terrain and low altitude of charge region during non-convective season (September to March), since we note that self-initiated lightning at the GBT occurred predominantly (79% or 142/179) during non-convective season. On the other hand the majority (85% or 22/26) of nearby-lightning-triggered upward flashes at the GBT occurring during convective season (April to August) and 80 nearby-lightning-triggered upward flashes out of 81 upward flashes observed at the ten tall towers in Rapid City in South Dakota of USA occurring during summer seasons, could be due to the result of high altitude of charge region. The triggering flashes were detected to be within 1 and 18 km distance and the time intervals between them and upward lightning initiation are in the range of 0.3 to 90.7 ms.

  17. Underlying mechanism of precursory activity from analysis of upward earthquake migration

    Directory of Open Access Journals (Sweden)

    O. A. Molchanov

    2011-01-01

    Full Text Available In this paper we analyse the upward earthquake hypocentral migration in the ten known subduction zones and discuss a possible mechanism of such migration. The total time of the migration appears to range from 2.5 to 10 years. It leads to the estimation of the average velocity Vz~ 60−300 km yr−1. It probably corresponds to the movement of the forcing agent like stress or deformation wave from depths of the upper mantle (600–700 km to the level of the lithosphere with subsequent initiation of fluid migration inside the crust to trigger shallow earthquakes. Averaged over all zones upward migration travel time is about 5 years (< Vz > ≈120 km yr−1 that coincides approximately with the period of characteristic temperature variation (El Nino and crustal seismic periodicity in the Pacific region. These findings are helpful for the study of the seismic precursors and analysis of earthquake triggering.

    Socioeconomic status (SES) is relatively stable across generations, but social policies may create opportunities for upward social mobility among disadvantaged populations during periods of economic growth. With respect to expanded educational opportunities that occurred in Québec (Canada) during the 1960s, we hypothesized that children's social and academic competence would promote upward mobility, whereas aggression and social withdrawal would have the opposite effect. Out of 4,109 children attending low-SES schools in 1976-1978, a representative subsample of 503 participants were followed until midadulthood. Path analyses revealed that parents' SES predicted offspring's SES through associations with offspring's likeability, academic competence, and educational attainment. Interaction effects revealed individual risk factors that moderated children's ability to take advantage of intrafamilial or extrafamilial opportunities that could enhance their educational attainment. Highly aggressive participants and those presenting low academic achievement were unable to gain advantage from having highly educated parents. They reached lower educational attainment than their less aggressive or higher achieving peers who came from a similarly advantaged family background. Growing up with parents occupying low-prestige jobs put withdrawn boys and outgoing girls at risk for low educational attainment. In conclusion, social policies can raise SES across generations, with great benefits for the most disadvantaged segments of the population. However, children presenting with emerging psychopathology or academic weaknesses do not benefit from these policies as much as others, and should receive additional, targeted services.

  19. EXPERIMENTAL INVESTIGATION OF CONVECTIVE HEAT TRANSFER IN A NARROW RECTANGULAR CHANNEL FOR UPWARD AND DOWNWARD FLOWS

    Directory of Open Access Journals (Sweden)

    DAESEONG JO

    2014-04-01

    Full Text Available Heat transfer characteristics in a narrow rectangular channel are experimentally investigated for upward and downward flows. The experimental data obtained are compared with existing data and predictions by many correlations. Based on the observations, there are differences from others: (1 there are no different heat transfer characteristics between upward and downward flows, (2 most of the existing correlations under-estimate heat transfer characteristics, and (3 existing correlations do not predict the high heat transfer in the entrance region for a wide range of Re. In addition, there are a few heat transfer correlations applicable to narrow rectangular channels. Therefore, a new set of correlations is proposed with and without consideration of the entrance region. Without consideration of the entrance region, heat transfer characteristics are expressed as a function of Re and Pr for turbulent flows, and as a function of Gz for laminar flows. The correlation proposed for turbulent and laminar flows has errors of ±18.25 and ±13.62%, respectively. With consideration of the entrance region, the heat transfer characteristics are expressed as a function of Re, Pr, and z* for both laminar and turbulent flows. The correlation for turbulent and laminar flows has errors of ±19.5 and ±22.0%, respectively.

  20. The upward-driven pendulum: a (mechanical) toy model of convection

    Science.gov (United States)

    Maas, L. R. M.; Buijsman, D. J.

    2003-04-01

    A mechanical toy model of convection will be presented. It consists of a pendulum that is clamped in between two cogwheels that drive it upwards. As soon as the centre-of-mass is raised above the vertical position of the horizontal axis around which the pendulum can rotate, gravity will cause the pendulum to topple. Once the centre-of-mass is below the axial position, the rotation sense of the coghweels is changed, and the pendulum is again driven upwards. The height to which the pendulum grows depends sensitively upon the angle between gravity and pendulum (which has been checked in a certain direction as soon as its angular momentum has been drained by friction). Depending on the driving speed, this may lead to chaotic or regular behaviour of the pendulum. This behaviour mimicks that of the one-parameter, diffusionless Lorenz equations [2], itself a simplification of the Lorenz-63 equations, which govern also the dynamics of the centre-of-mass of a uniformly stratified fluid subject to differential heating [1]. This suggests an interpretation of convection in terms of the (possibly chaotic) dynamics of the centre-of-mass of a fluid.

    Parameters of upward initiated lightning from tall objects are gaining increasing interest in recent years. This is a result of the installation of tall objects (wind turbines, radio towers, etc.) experiencing a high number of lightning flashes. Lightning current waveforms of flashes initiated from the Gaisberg Tower (GBT) in Austria are continuously measured since 1998. On average this radio tower (tower height 100 m) located on a small mountain (1287 m ASL) next to the city of Salzburg triggers about 60-70 flashes per year. More than 50% of the triggered flashes occurred during cold season (similar to so-called winter lightning in Japan) and more or less independent of the overall thunderstorm activity in Austria. Up to now, more than 800 flashes have been recorded by employing a 0.25 mΩ shunt at the tower top. Compared to inductive sensors, with their limited lower bandwidth, a shunt allows correct measurement of the slowly varying, low amplitude initial continuing current (ICC). ICCs are lasting for several hundreds of milliseconds and they are the main contributors to the transferred charge by a flash. Maximum transferred charge in a single flash was 783 C and this negative flash was recorded during cold season on October15th, 2012. Contrary to observations in winter lightning in Japan, where upward initiated flashes with very large charge transfer are predominantly bipolar, at the GBT 7 out of the 10 flashes exceeding a charge transfer of 300 C were negative, 2 were positive and 1 bipolar. Most of the flashes (93%) triggered by the GBT are of negative polarity, initiated by a positive upward propagating leader. But also positive (4%) and bipolar (3%) flashes are observed at the GBT. In case of negative lightning flashes, 45% of current records exhibit an ICC only, 23% of flashes has pulses of peak current exceeding 2 kA superimposed on the ICC, and return strokes following the ICC after a period of "no current" is observed in 32% of the events.

    Background An increasing number of young women Veterans seek reproductive health care through the VA, yet little is known regarding the provision of infertility care for this population. The VA provides a range of infertility services for Veterans including artificial insemination, but does not provide in vitro fertilization. This study will be the first to characterize infertility care among OEF/OIF/OND women Veterans using VA care. Methods We analyzed data from the OEF/OIF/OND roster file from the Defense Manpower Data Center (DMDC)—Contingency Tracking System Deployment file of military discharges from October 1, 2001–December 30, 2010, which includes 68,442 women Veterans between the ages of 18 and 45 who utilized VA health care after separating from military service. We examined the receipt of infertility diagnoses and care using ICD-9 and CPT codes. Results Less than 2% (n = 1323) of OEF/OIF/OND women Veterans received an infertility diagnosis during the study period. Compared with women VA users without infertility diagnosis, those with infertility diagnosis were younger, obese, black, or Hispanic, have a service-connected disability rating, a positive screen for military sexual trauma, and a mental health diagnosis. Overall, 22% of women with an infertility diagnosis received an infertility assessment or treatment. Thirty-nine percent of women Veterans receiving infertility assessment or treatment received this care from non-VA providers. Conclusions Overall, a small proportion of OEF/OIF/OND women Veterans received infertility diagnoses from the VA during the study period, and an even smaller proportion received infertility treatment. Nearly 40% of those who received infertility treatments received these treatments from non-VA providers, indicating that the VA may need to examine the training and resources needed to provide this care within the VA.

    Female Veterans comprise 12% of Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans, the largest proportion of women to serve of any prior cohort. We sought to determine the sex-specific risk of using a Veterans Health Administration (VHA) homeless program among OEF/OIF Veterans and to identify factors associated with increased risk of program use for women compared with men. We included OEF/OIF Veterans with at least 1 VHA clinical visit between October 1, 2001, and September 30, 2009. The study's outcome was the time to first use of a VHA homeless program. Cox proportional-hazards regression was used to estimate the relative risk of using a homeless program by sex, adjusting for relevant sociodemographic and clinical variables. Exploratory analyses examined interactions between sex and all covariates. Of 445,319 Veterans, 7431 (1.7%) used a VHA homeless program, of which 961 were females (1.8%), and 6470 were males (1.7%) during a median follow-up period of 3.20 years. Women were as likely as men to use a homeless program (adjusted hazard ratio, 1.02; 95% confidence interval, 0.95-1.09); median time to first use was similar for female and male Veterans (1.88 vs. 1.88 y, respectively, P=0.53). In exploratory analyses, we found increased risk of program use for women compared with men for the following subgroups: ages 26-35 years, 100% service-connected disability rating, posttraumatic stress disorder diagnosis, and northeast location. Overall, there was no substantial difference in the sex-specific risk of using a VHA homeless program. In light of this finding, VHA homeless programs must be prepared to recognize and address the unique needs of female OEF/OIF Veterans.

    Millions of disadvantaged youth and returning veterans are enrolled in community colleges. Our objective was to determine the prevalence of mental disorders and help-seeking behaviors among community college students. Veterans (n=211) and non-veterans (n=554) were recruited from 11 community colleges and administered screeners for depression (PHQ-9), generalized anxiety (GAD-7), posttraumatic stress disorder (PC-PTSD), non-lethal self-injury, suicide ideation and suicide intent. The survey also asked about the perceived need for, barriers to and utilization of services. Regression analysis was used to compare prevalence between non-veterans and veterans adjusting for non-modifiable factors (age, gender and race/ethnicity). A large proportion of student veterans and non-veterans screened positive and unadjusted bivariate comparisons indicated that student veterans had a significantly higher prevalence of positive depression screens (33.1% versus 19.5%, Pdepression (OR=2.10, P=.01) and suicide ideation (OR=2.31, P=.03). Student veterans had significantly higher odds of perceiving a need for treatment than non-veterans (OR=1.93, P=.02) but were more likely to perceive stigma (beta=0.28, P=.02). Despite greater need among veterans, there were no significant differences between veterans and non-veterans in use of psychotropic medications, although veterans were more likely to receive psychotherapy (OR=2.35, P=.046). Findings highlight the substantial gap between the prevalence of probable mental health disorders and treatment seeking among community college students. Interventions are needed to link community college students to services, especially for student veterans. Copyright © 2016. Published by Elsevier Inc.

  7. Lower bounds for randomized Exclusive Write PRAMs

    1995-05-02

    In this paper we study the question: How useful is randomization in speeding up Exclusive Write PRAM computations? Our results give further evidence that randomization is of limited use in these types of computations. First we examine a compaction problem on both the CREW and EREW PRAM models, and we present randomized lower bounds which match the best deterministic lower bounds known. (For the CREW PRAM model, the lower bound is asymptotically optimal.) These are the first non-trivial randomized lower bounds known for the compaction problem on these models. We show that our lower bounds also apply to the problem of approximate compaction. Next we examine the problem of computing boolean functions on the CREW PRAM model, and we present a randomized lower bound, which improves on the previous best randomized lower bound for many boolean functions, including the OR function. (The previous lower bounds for these functions were asymptotically optimal, but we improve the constant multiplicative factor.) We also give an alternate proof for the randomized lower bound on PARITY, which was already optimal to within a constant additive factor. Lastly, we give a randomized lower bound for integer merging on an EREW PRAM which matches the best deterministic lower bound known. In all our proofs, we use the Random Adversary method, which has previously only been used for proving lower bounds on models with Concurrent Write capabilities. Thus this paper also serves to illustrate the power and generality of this method for proving parallel randomized lower bounds.

  8. Migration by Veterans Who Received Homeless Services From the Department of Veterans Affairs.

    2016-10-01

    We examined migration patterns among 113,400 homeless veterans, focusing on the prevalence and the basic geographic patterns of this migration. Data were for all veterans who initiated use of Veterans Affairs homeless services in 2011 or 2012; and we followed them using Veterans Affairs administrative records for up to 2 years following this initial contact. Results showed that 15.3% of the veterans migrated across regions while homeless. Those who were homeless for longer periods were more likely to migrate, and migration, were it to occur, was most likely earlier on in veterans' homelessness episodes. There were no clear geographic correlates that explained the dynamics of this migration as, overall, in-migration tended to roughly balance out-migration in a region. These findings suggest that concerns about the extent of migration and its impact on localities are exaggerated, but also sets forth an agenda for more in-depth study of these data to gain a deeper and more expansive understanding of this phenomenon.

    2017-10-01

    In this analysis of a cohort of older homeless veterans, we examined psychosocial, health, housing, and employment characteristics to identify predictors of mortality. Our sample of 3,620 older veterans entered Veteran Affairs homeless programs in years 2000-2003. Fifteen variables from a structured interview described this sample and served as predictors. National Death Index data for years 2000-2011 were used to ascertain death. Survival table analyses were conducted to estimate and plot cumulative survival functions. To determine predictors and estimate hazard functions, Cox proportional hazards regression analysis was conducted. Five variables (presence of a serious health issue, hospitalization for alcohol abuse, alcohol dependency, unemployment for 3 years, and age 60+) were associated with increased risk of death; three (non-White, drug dependency, and dental problems) were associated with reduced risk. A risk score, based on total unit-weighted risk for all eight predictors, was used to identify three groups that were found to differ significantly in mortality. These analyses underline the jeopardy faced by older homeless veterans in terms of early death. We were able to identify several variables associated with mortality; more importantly, we were able to show that a risk score based on status for these variables was significantly related to survival.

    To identify sociodemographic and military characteristics of combat-exposed and non-combat-exposed veterans in the United States and to compare rates of mental and physical health conditions in these populations. Data were analyzed from the National Health and Resilience in Veterans Study (NHRVS), a contemporary, nationally representative survey of 1,480 US veterans conducted September-October 2013. Poststratification weights were applied to analyses to permit generalizability of results to the US veteran population. Outcomes measured included lifetime and current psychiatric disorders and physical health conditions. A total 38% of US veterans reported being exposed to combat. Compared to noncombat veterans, combat veterans were younger, had greater household income, and served a greater number of years in the military; were more likely to be male, to have served in the Marine Corps, and to use the Veterans Affairs Healthcare System as their main source of health care; and reported a greater number of lifetime potentially traumatic events. After adjustment for these sociodemographic and military differences, combat veterans were more than 3 times as likely as noncombat veterans to screen positive for lifetime posttraumatic stress disorder (PTSD) and more than twice as likely for current PTSD and had 82% greater odds of screening positive for current generalized anxiety disorder. After additionally controlling for lifetime diagnoses of PTSD and depression, alcohol or drug use disorder, and nicotine dependence, combat veterans had 68% greater odds of having attempted suicide and 85% and 38% greater odds of being diagnosed with a stroke and chronic pain, respectively. Younger combat veterans were more likely than older combat veterans to screen positive for lifetime (30.6% vs 10.1%) and current PTSD (19.2% vs 4.9%) and suicidal ideation (18.6% vs 6.9%) and to have been diagnosed with migraine headaches (12.8% vs 2.1%), while older combat veterans were more likely than

Hierarchical regression analyses revealed that partner alcohol and drug use severity explained more variance in veteran alcohol use and drug use (20% and 13%, respectively) than did veteran PTSD, adult antisocial behavior, or depression symptoms combined (6% for veteran alcohol use; 7% for veteran drug use). Findings shed new light on the influence of relationship factors on veteran alcohol and drug use and underscore the importance of couples-oriented approaches to treating veterans with comorbid PTSD and substance abuse.

  6. Far-zone contributions of airborne gravity anomalies' upward/downward continuation

    2016-11-01

    Full Text Available Airborne gravimetry has become a vital technique in local gravity field approximation, and upward/downward continuation of gravity data is a key process of airborne gravimetry. In these procedures, the integral domain is divided into two parts, namely the near-zone and the far-zone. The far-zone contributions are approximated by the truncation coefficients and a global geo-potential model, and their values are controlled by several issues. This paper investigates the effects of flight height, the size of near-zone cap, and Remove-Compute-Restore (RCR technique upon far-zone contributions. Results show that at mountainous area the far-zone contributions can be ignored when EIGEN-6C of 360 degree is removed from the gravity data, together with a near-zone cap of 1° and a flight height less than 10 km, while at flat area EIGEN-6C of 180 degree is feasible.

    In this paper the first study of the upward going events detected by the telescopes of the Extreme Energy Event (EEE) project is reported. The EEE project consists of a detector array of Multigap Resistive Plate Chambers located at selected sites on the Italian territory. During autumn 2014 the first coordinated data taking period took place and around one billion candidate tracks were collected. Among them, of particular interest is the sample of particles which cross the telescopes from below. The results obtained demonstrate that the EEE telescopes can distinguish the electrons produced as decay products of cosmic muons stopped in the ground, or in the last chamber of the telescopes themselves, confirming the excellent performance of the system for the investigation of intriguing cosmic phenomena.

    2017-03-01

    Co growth on Cu(111) was investigated at several temperatures between 120 K and 300 K by variable-temperature fast-scanning tunneling microscopy at submonolayer coverage. Islands nucleate heterogeneously at step edges and homogeneously on terraces. The height and area distribution difference between these two types of differently nucleated islands is attributed to a step edge alloy. Furthermore, the transformation from one-monolayer high islands to two-monolayer high islands is followed in time-lapsed sequences between 145 and 165 K. A surprising low-energy barrier for upward mass transport of Eupward≈(0.15 ±0.04 ) eV is determined for islands on terraces. At 120 and 150 K, the terrace islands are pure Cu; in contrast, at room temperature, terrace islands larger than ≈120 nm2 alloy at their border.

    In this paper the first study of the upward going events detected by the telescopes of the Extreme Energy Event (EEE) project is reported. The EEE project consists of a detector array of Multigap Resistive Plate Chambers located at selected sites on the Italian territory. During autumn 2014 the first coordinated data taking period took place and around one billion candidate tracks were collected. Among them, of particular interest is the sample of particles which cross the telescopes from below. The results obtained demonstrate that the EEE telescopes can distinguish the electrons produced as decay products of cosmic muons stopped in the ground, or in the last chamber of the telescopes themselves, confirming the excellent performance of the system for the investigation of intriguing cosmic phenomena.

  10. Treatment of a coxofemoral luxation secondary to upward fixation of the patella in a Shetland pony.

    Clegg, P D; Butson, R J

    1996-02-10

    A nine-year-old Shetland pony gelding, with a history of recurrent upward fixation of the patella, suddenly developed severe lameness in its right hindlimb. A luxation of the coxofemoral joint was diagnosed by a clinical and radiographic examination. The initial treatment of the luxation by closed reduction was not maintained, and the limb was placed in an Ehmer sling for four days after a second closed reduction. This allowed the femoral head to remain in the acetabulum, although a persistent subluxation remained, presumably owing to a rupture of the round ligament. The pony remained comfortable at pasture for over two years after the reduction, until osteoarthritis of the coxofemoral joint caused it to become severely lame and it had to be euthanased.

  11. UPWARD SOCIAL MOBILITY OF INDIVIDUALS FROM MINORITY GROUPS: A CASE STUDY OF ROMA WOMENIN HIGHER EDUCATION

    Irina ILISEI

    2014-06-01

    Full Text Available In this paper I investigate the phenomena of social mobility of women from patriarchal communities and the low rates of social upward mobility of women having an ethnic minority background. The aim is to identify the factors that influence access to higher education for Roma women living in Romania. I examine the interaction between social, economic, cultural and institutional factors. This paper offers a clearer understanding of the interconnections between different factors in the decision making of women from minority communities who seek a higher socio-economic status. The results of this research are based on empirical evidence through qualitative research. The paper has an interdisciplinary perspective, though the main approach derives from sociology and political science (policy analysis. An important input in this research comes from a gender studies perspective, especially related to the analysis of the intersection between gender, class and ethnicity.

  16. Capacity Bounds for Parallel Optical Wireless Channels

    KAUST Repository

    Chaaban, Anas

    2016-01-01

    A system consisting of parallel optical wireless channels with a total average intensity constraint is studied. Capacity upper and lower bounds for this system are derived. Under perfect channel-state information at the transmitter (CSIT), the bounds have to be optimized with respect to the power allocation over the parallel channels. The optimization of the lower bound is non-convex, however, the KKT conditions can be used to find a list of possible solutions one of which is optimal. The optimal solution can then be found by an exhaustive search algorithm, which is computationally expensive. To overcome this, we propose low-complexity power allocation algorithms which are nearly optimal. The optimized capacity lower bound nearly coincides with the capacity at high SNR. Without CSIT, our capacity bounds lead to upper and lower bounds on the outage probability. The outage probability bounds meet at high SNR. The system with average and peak intensity constraints is also discussed.

  17. Performance Bounds of Quaternion Estimators.

    Xia, Yili; Jahanchahi, Cyrus; Nitta, Tohru; Mandic, Danilo P

    2015-12-01

    The quaternion widely linear (WL) estimator has been recently introduced for optimal second-order modeling of the generality of quaternion data, both second-order circular (proper) and second-order noncircular (improper). Experimental evidence exists of its performance advantage over the conventional strictly linear (SL) as well as the semi-WL (SWL) estimators for improper data. However, rigorous theoretical and practical performance bounds are still missing in the literature, yet this is crucial for the development of quaternion valued learning systems for 3-D and 4-D data. To this end, based on the orthogonality principle, we introduce a rigorous closed-form solution to quantify the degree of performance benefits, in terms of the mean square error, obtained when using the WL models. The cases when the optimal WL estimation can simplify into the SWL or the SL estimation are also discussed.

  18. Spectral computations for bounded operators

    2001-01-01

    Exact eigenvalues, eigenvectors, and principal vectors of operators with infinite dimensional ranges can rarely be found. Therefore, one must approximate such operators by finite rank operators, then solve the original eigenvalue problem approximately. Serving as both an outstanding text for graduate students and as a source of current results for research scientists, Spectral Computations for Bounded Operators addresses the issue of solving eigenvalue problems for operators on infinite dimensional spaces. From a review of classical spectral theory through concrete approximation techniques to finite dimensional situations that can be implemented on a computer, this volume illustrates the marriage of pure and applied mathematics. It contains a variety of recent developments, including a new type of approximation that encompasses a variety of approximation methods but is simple to verify in practice. It also suggests a new stopping criterion for the QR Method and outlines advances in both the iterative refineme...

    Significant variability exists regarding the criteria and procedures used by different veterans' courts (VCs) across the country. Limited guidance is available regarding which VC model has the most successful outcomes. The purpose of this study was to examine factors associated with incarceration during VC participation. This study used data for 1,224 veterans collected from the HOMES (Homeless Operations Management and Evaluation System) database of the Department of Veterans Affairs, as well as data from a national phone survey inventory of all U.S. VCs. To identify variables associated with incarceration during VC participation, four backward conditional logistic regressions were performed. The following variables were associated with higher rates of incarceration because of a veteran's noncompletion of the VC program: charges of probation or parole violations, longer stays in the VC program, end of VC participation because of incarceration for a new arrest or case transfer by the legal system, and requiring mental health follow-up but not undergoing treatment. The following variables were associated with lower rates of incarceration: stable housing and participating in a VC program that referred veterans for substance abuse treatment. This study offers VCs a thorough review of an extensive set of recidivism data. Further investigation is necessary to understand the impact of VCs.

  1. The Influence of Upward Groundwater between Joints on the Stability and the Behavior of Dip Slope Failures

    In recent years, landslides have attracted much attention in the engineering field in Taiwan. As previous studies, landslides are induced by earthquakes, rainfall, and groundwater. That groundwater flows into upper layer through vertical joints, upward groundwater, erodes the slope and reduces its stability. Nevertheless, in the literature, the impact of upward groundwater to the location of sliding surface and the behaviors of dip slope failure has not be investigated. In this study, physical model tests with water flow inclinometers are used to investigate the kinematics of dip slope failures under various conditions and to identify the failure modes of specimens (Fig. 1). Besides, the mechanics of one landslide case owing to upward groundwater is studied by numerical simulation. In the physical tests, the effects of upward groundwater on slope stability are investigated with different angles of inclinometers, different position of joints on specimens and different locations of upward seepage. The test results suggest that the upward water pressure becomes lower when the number of joints increases. As the water pressure increases to 3.8 times the weight of one block of the specimen, the block will slide. Another, when the specimen is covered by one granular content layer (see Fig. 2), the failure surface tends to develop at the granular content layer, and its kinematics is similar to debris slide; when the clay seam is below of the specimen, the translational slide occurs along the bottom of the blocks. Moreover, one dip slope case, Taiwan's National Highway No. 3 landslide event, are studied by numerical simulation. According to the results, some points are concluded: water pressure makes tension cracks on the top of the vertical joints on weathered sandstones; with anchor attenuation, the sandstone moves downslope, which makes the shear strain of the slope toe region increases (see Fig. 3). If friction angle of the slope decreases, the slide surface occurs

    Male partner reproductive coercion is defined as male partners' attempts to promote pregnancy through interference with women's contraceptive behaviors and reproductive decision-making. Male partners may try to promote pregnancy through birth control sabotage such as taking away or destroying their partners' contraceptives, refusing to wear condoms, and/or verbally pressuring their partners to abstain from contraceptive use. Reproductive coercion is associated with an elevated risk for unintended pregnancy. Women who experience intimate partner violence, who are in racial/ethnic minorities, and who are of lower socioeconomic status are more likely to experience reproductive coercion. Women veterans who use Veterans Affairs for health care may be particularly vulnerable to reproductive coercion because they are disproportionally from racial/ethnic minority groups and experience high rates of intimate partner violence. We sought to examine the prevalence, correlates, and impact of reproductive coercion among women veterans who are served by the Veterans Affairs healthcare system. We analyzed data from a national telephone survey of women veterans aged 18-44 years, with no history of sterilization or hysterectomy, who had received care within the Veterans Affairs system in the previous 12 months. Participants who had sex with men in the last year were asked if they experienced male partner reproductive coercion. Adjusted logistic regression was used to examine the relationship between participant characteristics and male partner reproductive coercion and the relationship between reproductive coercion and the outcomes of contraceptive method used at last sex and pregnancy and unintended pregnancy in the last year. Among the 1241 women veterans in our study cohort, 11% reported experiencing male partner reproductive coercion in the past year. Black women, younger women, and single women were more likely to report reproductive coercion than their white, older, and

    Upward continuous casting was used to manufacture Cu-Cr-Ag high-strength high-conductivity alloys, for comparison with conventional processing methods. The behavior of the alloy samples was measured, including tensile strength, microhardness, and electrical conductivity. The microstructure was characterized using optical microscopy and transmission electron microscopy after each processing step. It was found that microstructure with columnar grains due to upward continuous casting made it possible to enhance strength whilst maintaining the ductility of the alloys during the aging process. The combined drawing-aging process has the potential to be used numerous times during the manufacture of Cu-Cr-based high-strength high-conductivity alloys.

  5. Using tolerance bounds in scientific investigations

    Energy Technology Data Exchange (ETDEWEB)

    Wendelberger, J.R.

    1996-07-01

    Assessment of the variability in population values plays an important role in the analysis of scientific data. Analysis of scientific data often involves developing a bound on a proportion of a population. Sometimes simple probability bounds are obtained using formulas involving known mean and variance parameters and replacing the parameters by sample estimates. The resulting bounds are only approximate and fail to account for the variability in the estimated parameters. Tolerance bounds provide bounds on population proportions which account for the variation resulting from the estimated mean and variance parameters. A beta content, gamma confidence tolerance interval is constructed so that a proportion beta of the population lies within the region bounded by the interval with confidence gamma. An application involving corrosion measurements is used to illustrate the use of tolerance bounds for different situations. Extensions of standard tolerance intervals are applied to generate regression tolerance bounds, tolerance bounds for more general models of measurements collected over time, and tolerance intervals for varying precision data. Tolerance bounds also provide useful information for designing the collection of future data.

    The aim of this study was to determine rates and consequences of suicide exposure in a veteran population and variables related to psychiatric morbidity. 931 veterans from a random digit dial survey conducted July 2012-June 2013 in the Commonwealth of Kentucky was utilized to examine associations between suicide exposure and depression and anxiety. For those with lifetime suicide exposure, perceptions of closeness to the decedent and additional traumatic death exposure were also examined. Almost half of veterans (47.1%, n=434) reported lifetime exposure to suicide. Suicide-exposed individuals were almost twice as likely to have diagnosable depression (OR=1.92, CI=1.31-2.8) and more than twice as likely to have diagnosable anxiety (OR=2.37, CI=1.55-3.61). Suicide-exposed were also more likely than non-exposed to report suicide ideation (9.9% vs. 4.3%). Perceived closeness to decedent increased the odds of depression (OR=1.38, CI=1.12-1.69), anxiety (OR=1.51, CI=1.21-1.89) and PTSD (OR=1.65, CI=1.27-2.16) and more than doubled the odds of Prolonged Grief (OR=2.47, CI=1.60-3.83). A model examined time sequence of suicide and traumatic death exposure. Experiencing a suicide exposure first and subsequent traumatic death exposure in their military career almost quadrupled the odds of suicide ideation (OR=3.56, p=.01, CI=1.34-9.46). Major study limitations include use of only one US state and random digit dial response rate. Suicide exposure confers psychiatric risks in veterans. Perceptions of closeness to decedents, which may extend beyond familial lines, may heighten these risks in the suicide exposed. Multiple exposures to suicide and traumatic death may lead to significant suicide risk. Copyright © 2015 Elsevier B.V. All rights reserved.

    Australian Defence Force (ADF) personnel participated in the Vietnam Conflict from 1962 to 1973, involving nearly 60,000 personnel, of whom over 500 died during service and 3131 were severely physically wounded. Service in the Vietnam conflict presented distinct health challenges. Besides the hazards of combat conditions for extended periods, herbicides and other toxic chemicals were used extensively. The United States military sprayed more than 76,000,000L of herbicide over Vietnam in their Air Force Ranch Hand and Operation Trail Dust programs. The most heavily used herbicide was Agent Orange, contaminated with 2,3,7,8-tetrachlorodibenzo-pdioxin. Since the Vietnam conflict, ex-Service organisations (ESOs) have maintained that Vietnam service adversely affected the health of veterans. Initial studies showed no excess risk attributable to their service. However, more recent studies have shown that Vietnam veterans have excess incidence and mortality rates from several conditions such as cancers and heart disease. This paper describes the first cancer incidence study for all ADF Vietnam veterans.

  19. Explanation of non-symmetric upward and downward diffusion during fluid injection

    Science.gov (United States)

    Hamidi, Sahar; Heinze, Thomas; Galvan, Boris; Miller, Stephen A.

    2017-04-01

    Non-symmetric upward and downward pressure diffusion from the point of injection is an often observed phenomenon in fluid-triggered seismicity. It has been observed during hydraulic stimulation of deep geothermal reservoirs as well as during natural CO2 triggered seismic swarms, like during the 2008 swarm and earlier ones in Bohemia / Vogtland area. In recent studies, a diverse set of models is used to describe this phenomenon; most commonly utilizing a stress and pressure-dependent permeability, causing higher permeability upwards than downwards. Though, such models often lead to unrealistic large permeability gradients. Besides a mechanical reason, also temperature and density contrasts are possible sources for a non-symmetric diffusion process. A temperature gradient in depth influences fluid properties with depth and salinity causes buoyancy. In this work, we compare all these possible sources, to identify to which extend every one of them could cause such non-symmetric diffusion. We perform our simulations with water, and also derive conclusions for CO2 as a triggering fluid. Although in reality, a mixture of all sources may occur, we find that temperature has by far the strongest influence on non-symmetric diffusion processes, especially considering that many regions in which this phenomenon was observed, exhibit a large temperature gradient. A stress dependent permeability also causes non-symmetric diffusion, but assuming realistic permeability gradients, the influence is limited. Salinity has been found to play only a minor role. Due to the even stronger temperature dependence of CO2 properties, the effect of temperature on CO2 driven seismicity is larger than on water. In the case of infiltrating CO2, depending on the host rock situation, also buoyancy can become significantly large, assuming that the injection timescale is too short for CO2 to dissolve in the pore water of the host system. Our results indicate the importance of a realistic heat transfer

    2014-01-01

    Since 2009, the U.S. Veterans Administration has made concentrated efforts to end homelessness among veterans. As part of these efforts, the Iowa City, Iowa, VA Health Care System in collaboration with local community providers deployed a supportive housing program aimed at homeless veterans. Called the Lodge program, it is intended to serve a Mid-Western mid-size city and its surrounding rural communities. This article presents qualitative findings from a mixed-method, two-year formative evaluation of the Lodge's implementation. Primary barriers to the effectiveness of the Lodge program were regulations hindering cooperation between service programs, followed by problems regarding information sharing and client substance abuse. Facilitators included personal communication and cooperation between individuals within and among service groups. The feasibility of implementing a Lodge program in a more rural community than Iowa City was also discussed.

    The Veterans Health Administration (VA) provides comprehensive health care services to veterans across the United States. Recently, the VA established an Office of Rural Health to address the health care needs of rural veterans. To review the literature on rural veterans' health care needs in order to identify areas for future research. We conducted a literature review of articles listed in the Medline, CINAHL, and BIOSIS datasets since 1950. We reviewed and summarized the findings of 50 articles that specifically examined rural veterans. The literature on rural veterans included 4 articles examining access to care, 7 evaluating distance technology, 4 examining new models of care delivery, 11 studying rural veterans' patient characteristics, 10 evaluating programs provided in a rural setting, 6 examining rural health care settings, and 8 exploring rural veterans' health services utilization patterns. Most studies were small, based on data obtained before 2000, and consisted of uncontrolled, retrospective, descriptive studies of health care provided in rural VA settings. Definitions of rural were inconsistent, and in 20% of the articles examined the rural aspect of the setting was incidental to the study. The literature on rural veterans' health care needs warrants expansion and investment so that policy makers can make informed decisions in an environment of limited resources and competing interests.

  2. Bound anionic states of adenine

    2007-03-20

    Anionic states of nucleic acid bases are involved in DNA damage by low-energy electrons and in charge transfer through DNA. Previous gas phase studies of free, unsolvated nucleic acid base parent anions probed only dipole-bound states, which are not present in condensed phase environments, but did not observe valence anionic states, which for purine bases, are thought to be adiabatically unbound. Contrary to this expectation, we have demonstrated that some thus far ignored tautomers of adenine, which result from enamine-imine transformations, support valence anionic states with electron vertical detachment energies as large as 2.2 eV, and at least one of these anionic tautomers is adiabatically bound. Moreover, we predict that the new anionic tautomers should also dominate in solutions and should be characterized by larger values of electron vertical detachment energy than the canonical valence anion. All of the new-found anionic tautomers might be formed in the course of dissociative electron attachment followed by a hydrogen atom attachment to a carbon atom, and they might affect the structure and properties of DNA and RNA exposed to low-energy electrons. The discovery of these valence anionic states of adenine was facilitated by the development of: (i) a new experimental method for preparing parent anions of nucleic acid bases for photoelectron experiments, and (ii) a new combinatorial/ quantum chemical approach for identification of the most stable tautomers of organic molecules.

    The partition function of the ABJM theory receives non-perturbative corrections due to instanton effects. We study these non-perturbative corrections, including bound states of worldsheet instantons and membrane instantons, in the Fermi-gas approach. We require that the total non-perturbative correction should be always finite for arbitrary Chern-Simons level. This finiteness is realized quite non-trivially because each bound state contribution naively diverges at some levels. The poles of each contribution should be canceled out in total. We use this pole cancellation mechanism to find unknown bound state corrections from known ones. We conjecture a general expression of the bound state contribution. Summing up all the bound state contributions, we find that the effect of bound states is simply incorporated into the worldsheet instanton correction by a redefinition of the chemical potential in the Fermi-gas system. Analytic expressions of the 3- and 4-membrane instanton corrections are also proposed.

    This study examined the influence of veterans' race and examiners' use of psychometric testing during a Department of Veterans Affairs posttraumatic stress disorder (PTSD) disability examination on diagnostic and service connection status outcomes. Participants were 764 veterans enrolled in a national longitudinal registry. Current and lifetime PTSD diagnostic status was determined with the Structured Clinical Interview for DSM-IV (SCID) and was compared with PTSD diagnosis conferred upon veterans by their compensation and pension (C&P) examiners as well as with ultimate Veterans Affairs (VA) PTSD service connected status. The concordance rate between independent SCID current PTSD diagnosis and PTSD disability examination diagnosis was 70.4%, and between SCID lifetime PTSD diagnosis and PTSD disability examination diagnosis was 77.7%. Among veterans with current SCID diagnosed PTSD, Black veterans were significantly less likely than White veterans to receive a PTSD diagnosis from their C&P examiner (odds ratio [OR] = .39, p = .003, confidence interval [CI] = .20-.73). Among veterans without current SCID diagnosed PTSD, White veterans were significantly more likely than Black veterans to receive a PTSD diagnosis from their C&P examiner (OR = 4.07, p = .005, CI = 1.51-10.92). Splitting the sample by use of psychometric testing revealed that examinations that did not include psychometric testing demonstrated the same relation between veteran race and diagnostic concordance. However, for examinations in which psychometric testing was used, the racial disparity between SCID PTSD status and disability exam PTSD status was no longer significant. Results suggest that psychometric testing may reduce disparities in VA PTSD disability exam outcomes. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    Combat deployment and reintegration are challenging for service members and their families. Although family involvement in mental health care is increasing in the U.S. Department of Veterans Affairs (VA) system, little is known about family members' preferences for services. This study elicited the perspectives of returning Afghanistan and Iraq war veterans with posttraumatic stress disorder and their families regarding family involvement in veterans' mental health care. Semistructured qualitative interviews were conducted with 47 veterans receiving care for posttraumatic stress disorder at the Central Arkansas Veterans Healthcare System or Oklahoma City VA Medical Center and 36 veteran-designated family members. Interviews addressed perceived needs related to veterans' readjustment to civilian life, interest in family involvement in joint veteran/family programs, and desired family program content. Interview data were analyzed using content analysis and constant comparison. Both groups strongly supported inclusion of family members in programs to facilitate veterans' postdeployment readjustment and reintegration into civilian life. Both desired program content focused on information, practical skills, support, and gaining perspective on the other's experience. Although family and veteran perspectives were similar, family members placed greater emphasis on parenting-related issues and the kinds of support they and their children needed during and after deployment. To our knowledge, this is the first published report on preferences regarding VA postdeployment reintegration support that incorporates the perspectives of returning male and female veterans and those of their families. Findings will help VA and community providers working with returning veterans tailor services to the needs and preferences of this important-to-engage population. (c) 2015 APA, all rights reserved).

    Distance bounding protocols are typically analyzed with respect to three types of attacks: Distance Fraud, Mafia Fraud, and Terrorist Fraud. We define a fourth main type of attacks on distance bounding protocols, called Distance Hijacking attacks. We show that many proposed distance bounding protocols are vulnerable to these attacks, and we propose solutions to make these protocols resilient to Distance Hijacking. Additionally, we generalize Distance Hijacking to Location Hijacking, to which ...

    The bubble dynamics and consequent changes in the liquid-phase flow characteristics in an upward bubbly square pipe with sudden expansion (expansion ratio of 2.0) are experimentally studied in this work. The experiments are conducted under two Reynolds numbers of 600 (laminar) and 6600 (turbulent), respectively, based on the inlet bulk velocities of the single-phase (without bubbles) flow. The mean volume void fraction and averaged bubble size considered are 1% and 3.5 mm, respectively, and we use the high-speed two-phase particle image velocimetry and the shadowgraphy to measure the gas and liquid phases simultaneously. In addition, the particle tracking velocimetry is performed using two cameras to track the three-dimensional paths of each bubble. It is observed that lateral void fraction distribution change to core peak from wall peak after sudden expansion and peak at near the wall again after 3 times of inlet pipe width. Also, the reattachment length in the two-phase flow decreases compared to that of a single-phase flow, while smaller bubbles tend to migrate into the recirculation region and being trapped. Further discussions on the turbulence statistics and Reynolds number effects will be given. Supported by NRF Grant (NRF-2016R1C1B2012775) of the Korean Government.

    The upward sub-cooled forced convection in a rectangular channel is investigated experimentally. The aim of the present work is the studying of the local heat transfer phenomena. Concerning the experimentation: the n-pentane is used as a working fluid, the independent variables are: the velocity in the range from 0.04 to 0.086 m/s and heat flux density with values between 1.8 and 7.36 W/cm2. The results show that the local Nusselt number distribution is not uniform along the channel; however, uniformity is observed in the mean Nusselt number for Reynolds under 1600. On the other hand, a new correlation to predict the local fluid temperature is established as a function of local wall temperature. The wall's heat is dissipated under the common effect of the sub-cooled regime; therefore, the local heat transfer coefficient is increased. The study of the thermal equilibrium showed that for Reynolds less than 1500; almost all of the heat flux generated by the heater cartridges is absorbed by the fluid.

    Understanding the combustion behavior of materials in the elevated oxygen environments of habitable spacecraft is of utmost importance to crew safety and mission success. Currently, certification for unrestricted flight usage of a material with respect to flammability involves passing the Upward Flame Propagation Test of NASA-STD-6001B (Test 1). This test evaluates materials in a standardized test configuration for two failure criteria: self-extinguishment within 15 cm (6 in.) and the propensity of flame propagation by means of flaming material transfer. By the NASA standard, full-length samples are 30 cm (12 in.) in length; however, factors independent of the test method such as limited material availability or various nonstandard test configurations limit the full pretest sample lengths available for test. This paper characterizes the dependence, if any, of pretest sample length on NASA-STD-6001B Test 1 results. Testing was performed using the Maximum Oxygen Concentration (MOC) Threshold Method to obtain a data set for each sample length tested. In addition, various material types, including cloth (Nomex), foam (TA-301) and solids (Ultem), were tested to investigate potential effects of test specimen types. Though additional data needs to be generated to provide statistical confidence, preliminary findings are that use of variable sample lengths has minimal impact on NASA-STD-6001B flammability performance and MOC determination.

    Highlights: • Surface tension effects were clarified on annular flow in a small diameter pipe. • The mean liquid film thickness became thinner with decreasing of surface tension. • The liquid droplet fraction and the interfacial shear stress became higher with it. • New prediction methods for the above parameters were developed and validated. - Abstract: Experiments were conducted to study the surface tension effects on vertical upward annular flows in a 5 mm I.D. pipe using water and low surface tension water with a little surfactant as the test liquid and air as the test gas. Firstly, the experimental results on the mean liquid film thickness, the liquid droplet fraction and the interfacial shear stress in annular flows together with some flow pictures are presented to clarify the surface tension effects. From these, the followings are clarified: In the low surface tension case, the liquid film surface becomes rough, the liquid film thickness thin, the liquid droplet fraction high, and the interfacial shear stress high. Secondary, correlations in literatures for the respective parameters are tested against the present data. The test results show that no correlation for the respective parameters could predict well the present data. Thus, correlations are revised by accounting for the surface tension effects. The results of the experiments, the correlations tests and their revisions mentioned above are presented in the present paper.

    The report considers the relevance of the application of modern remote aerospace and hydrogeological methods in the problems of the ecological safety for the hydrosphere during shale gas production in Ukraine. Case studies of pilot implementation of these methods are present for the Bilyaivska area adjacent to the Yuzivka licensed site within the Dnieper-Donets Depression. A number of the hydrogeological filtration parameters and the thematic processing for remote sensing data of the Earth enable to obtain the rough estimate of the temporal indices for the upward pollutant migration from the fracturing zone to the groundwater aquifers in the potential process of shale gas production (as an example the 400-Bilyaivska well). It is found that the possible variety of the active permeability in tectonic zone, which may be predicted by using remote sensing of the Earth image interpretation in vicinity of the well, is responsible for the passage time of pollution from the fracturing zone level to the groundwater aquifers one and this time interval spans 50˜5 years.

  14. On the One-Dimensional Modeling of Vertical Upward Bubbly Flow

    Directory of Open Access Journals (Sweden)

    C. Peña-Monferrer

    2018-01-01

    Full Text Available The one-dimensional two-fluid model approach has been traditionally used in thermal-hydraulics codes for the analysis of transients and accidents in water–cooled nuclear power plants. This paper investigates the performance of RELAP5/MOD3 predicting vertical upward bubbly flow at low velocity conditions. For bubbly flow and vertical pipes, this code applies the drift-velocity approach, showing important discrepancies with the experiments compared. Then, we use a classical formulation of the drag coefficient approach to evaluate the performance of both approaches. This is based on the critical Weber criteria and includes several assumptions for the calculation of the interfacial area and bubble size that are evaluated in this work. A more accurate drag coefficient approach is proposed and implemented in RELAP5/MOD3. Instead of using the Weber criteria, the bubble size distribution is directly considered. This allows the calculation of the interfacial area directly from the definition of Sauter mean diameter of a distribution. The results show that only the proposed approach was able to predict all the flow characteristics, in particular the bubble size and interfacial area concentration. Finally, the computational results are analyzed and validated with cross-section area average measurements of void fraction, dispersed phase velocity, bubble size, and interfacial area concentration.

  15. Theory and observations of upward field-aligned currents at the magnetopause boundary layer.

    Wing, Simon; Johnson, Jay R

    2015-11-16

    The dependence of the upward field-aligned current density ( J ‖ ) at the dayside magnetopause boundary layer is well described by a simple analytic model based on a velocity shear generator. A previous observational survey confirmed that the scaling properties predicted by the analytical model are applicable between 11 and 17 MLT. We utilize the analytic model to predict field-aligned currents using solar wind and ionospheric parameters and compare with direct observations. The calculated and observed parallel currents are in excellent agreement, suggesting that the model may be useful to infer boundary layer structures. However, near noon, where velocity shear is small, the kinetic pressure gradients and thermal currents, which are not included in the model, could make a small but significant contribution to J ‖ . Excluding data from noon, our least squares fit returns log( J ‖,max_cal ) = (0.96 ± 0.04) log( J ‖_obs ) + (0.03 ± 0.01) where J ‖,max_cal = calculated J ‖,max and J ‖_obs = observed J ‖ .

    2008-01-01

    Full Text Available The problem of the laminar upward mixed convection heat transfer for thermally developing air flow in the entrance region of a vertical circular cylinder under buoyancy effect and wall heat flux boundary condition has been numerically investigated. An implicit finite difference method and the Gauss elimination technique have been used to solve the governing partial differential equations of motion (Navier Stocks equations for two-dimensional model. This investigation covers Reynolds number range from 400 to 1600, heat flux is varied from 70 W/m2 to 400 W/m2. The results present the dimensionless temperature profile, dimensionless velocity profile, dimensionless surface temperature along the cylinder, and the local Nusselt number variation with the dimensionless axial distance Z+. The dimensionless velocity and temperature profile results have revealed that the secondary flow created by natural convection have a significant effect on the heat transfer process. The results have also shown an increase in the Nusselt number values as the heat flux increases. The results have been compared with the available experimental study and with the available analytical solution for pure forced convection in terms of the local Nusselt number. The comparison has shown satisfactory agreement. .

  17. Calretinin inputs are confined to motoneurons for upward eye movements in monkey.

    Science.gov (United States)

    Zeeh, Christina; Hess, Bernhard J; Horn, Anja K E

    2013-10-01

    Motoneurons of extraocular muscles are controlled by different premotor pathways, whose selective damage may cause directionally selective eye movement disorders. The fact that clinical disorders can affect only one direction, e.g., isolated up-/downgaze palsy or up-/downbeat nystagmus, indicates that up- and downgaze pathways are organized separately. Recent work in monkey revealed that a subpopulation of premotor neurons of the vertical eye movement system contains the calcium-binding protein calretinin (CR). With combined tract-tracing and immunofluorescence, the motoneurons of vertically pulling eye muscles in monkey were investigated for the presence of CR-positive afferent terminals. In the oculomotor nucleus, CR was specifically found in punctate profiles contacting superior rectus and inferior oblique motoneurons, as well as levator palpebrae motoneurons, all of which participate in upward eye movements. Double-immunofluorescence labeling revealed that CR-positive terminals lacked the γ-aminobutyric acid (GABA)-synthesizing enzyme glutamate decarboxylase, which is present in inhibitory afferents to all motoneurons mediating vertical eye movements. Therefore, CR-containing afferents are considered to be excitatory. In conclusion, a strong CR input is confined to motoneurons mediating upgaze, which derive from premotor pathways mediating saccades and smooth pursuit, but not from secondary vestibulo-ocular neurons in the magnocellular part of the medial vestibular nucleus. The functional significance of CR in these connections is unclear, but it may serve as a useful marker to locate upgaze pathways in the human brain. © 2013 Wiley Periodicals, Inc.

    We reconsider the Gram-Hadamard bound as it is used in constructive quantum field theory and many body physics to prove convergence of Fermionic perturbative expansions. Our approach uses a recursion for the amplitudes of the expansion, discovered in a model problem by Djokic (2013). It explains the standard way to bound the expansion from a new point of view, and for some of the amplitudes provides new bounds, which avoid the use of Fourier transform, and are therefore superior to the standard bounds for models like the cold interacting Fermi gas.

  8. A macroscopic physical model for self-initiated upward leaders from tall grounded objects and its application

    Science.gov (United States)

    Chan, Ming-Kit; Chen, Mingli; Du, Ya-ping

    2018-02-01

    This paper presents a macroscopic physical model that can simulate an upward leader initiated from a tall grounded object under thunderclouds. Based on a tri-layer leader channel structure and the energy conservation law, a new equation for estimating the upward leader propagation speed is proposed. Equations for modeling other physical parameters, such as the leader line charge density, leader core radius, leader corona sheath radius, leader current, leader electric field and leader conductance, are also proposed. Besides, a set of initiation and survival criteria for a steady self-initiated upward leader from a tall grounded object is suggested. Based on the suggested criteria and the proposed model, the critical corona and charge amount as well as the minimum height for successful initiation of an upward positive leader (UPL) from a tall grounded object are evaluated and discussed. The model is then used to investigate the general properties of UPLs self-initiated from tall grounded objects with and without the effect of corona space charge layer near the ground under different thunderstorm conditions. The modelling results can well explain the leader properties observed in literature. The model is further tested with two set of experiment data and very promising results are obtained.

  13. Dispersive Behavior of the Mixing Zone between a Shallow Freshwater Lens and Upward Seeping Saline Groundwater

    Science.gov (United States)

    Eeman, S.; Leijnse, A.; van der Zee, S. E. A. T. M.

    2009-04-01

    Introduction Salt water intrusion and upward seepage of salt groundwater is a widespread problem in low-lying areas of coastal zones that are important for agriculture or ecology, such as in the North and West regions of the Netherlands, Southwest Florida, and many other deltaic areas, for example Camargue in France and the Nile delta in Egypt. Where the soil surface is situated below sea level, saline groundwater moves upward into superficial water networks. On the other hand, infiltrating rainwater forms small-scale fresh water lenses. The system is also comparable to the situation that develops when "skimming wells" are used, for example for irrigation in Northern India. The lenses we are studying have a thickness ranging from less then one up to several meters, their width depending on drainage density (generally 20-500 m). Field data show that the transition zone can be as thick as the fresh water lens itself. Therefore a sharp interface model cannot be assumed suitable to analyze such lenses (Sakr, 1999). When comparing numerical and analytical models for steady situations, when flow lines are parallel to the transition zone, we found that the analytical model represents the centre of the transition zone quite accurately. The width can be estimated only roughly. Climate change and human influence, through water level control and/or pumping, cause these lenses to grow or shrink. During this volume change, flow lines have a component perpendicular to the transition zone between fresh and saline water. This increases longitudinal dispersion, and thereby widens the transition zone further. Research This work is a combination of numerical modeling, dimension analysis and fieldwork; we use SUTRA (Voss and Provost, 2003), which is capable of including both density dependence and unsaturated zones. To characterize the shape of the lens and the transition zone we use spatial moments. For 2 sites in the Southwest of the Netherlands we are continuously monitoring

    This chapter reviews some work on bounded rationality, expectation formation and learning in complex markets, using the familiar demand-supply cobweb model. We emphasize two stories of bounded rationality, one story of adaptive learning and another story of evolutionary selection. According to the

    We prove that the spatial coagulation equation with bounded coagulation rate is well-posed for all times in a given class of kernels if the convection term of the underlying particle dynamics has divergence bounded below by a positive constant. Multiple coagulations, fragmentation and scattering are also considered.

    Full Text Available In this article, we formalize polynomially bounded sequences that plays an important role in computational complexity theory. Class P is a fundamental computational complexity class that contains all polynomial-time decision problems [11], [12]. It takes polynomially bounded amount of computation time to solve polynomial-time decision problems by the deterministic Turing machine. Moreover we formalize polynomial sequences [5].

    The National Center for Atmospheric Research (NCAR) Thermosphere Ionosphere Electrodynamics General Circulation Model (TIEGCM) will provide a physics-based context for the interpretation of ICON measurements. To optimize the realism of the model simulations, ICON wind and temperature measurements near the ˜97 km lower boundary of the TIEGCM will be used to specify the upward-propagating tidal spectrum at this altitude. This will be done by fitting a set of basis functions called Hough Mode Extensions (HMEs) to 27-day mean tidal winds and temperatures between 90 and 105 km altitude and between 12 °S and 42 °N latitude on a day-by-day basis. The current paper assesses the veracity of the HME fitting methodology given the restricted latitude sampling and the UT-longitude sampling afforded by the MIGHTI instrument viewing from the ICON satellite, which will be in a circular 27° inclination orbit. These issues are investigated using the output from a reanalysis-driven global circulation model, which contains realistic variability of the important tidal components, as a mock data set. ICON sampling of the model reveals that the 27-day mean diurnal and semidiurnal tidal components replicate well the 27-day mean tidal components obtained from full synoptic sampling of the model, but the terdiurnal tidal components are not faithfully reproduced. It is also demonstrated that reconstructed tidal components based on HME fitting to the model tides between 12 °S and 42 °N latitude provide good approximations to the major tidal components expected to be encountered during the ICON mission. This is because the constraints provided by fitting both winds and temperatures over the 90-105 km height range are adequate to offset the restricted sampling in latitude. The boundary conditions provided by the methodology described herein will greatly enhance the ability of the TIEGCM to provide a physical framework for interpreting atmosphere-ionosphere coupling in ICON observations

  5. Upward flow of magmatic fluids from the Old Woman granodiorite, Old Woman Mountains southeastern California

    Morrison, Jean; Hoisch, Thomas D.

    1994-05-01

    Isotopic compositions, mineral equilibrium, and field relations at the contact between the midcrustal Cretaceous Old Woman granodiorite and Paleozoic carbonates indicate that water-rich, silica-saturated magmatic fluids were transported upward, away from the pluton, across an impermeable 30- to 40-m thick marble which caps the granodiorite, to higher structural levels along a complex network of hydrologically induced fractures. Within the fractures, fluids reacted to form symmetrical radiating splays of wollastonite with minor amounts of diopside, vesuvianite, and quartz. In many cases, pegmatites are found in the center of these calc-silicate skarns. Cross-cutting pegmatites and wollastonite veins in the aureole indicate that during late stages of crystallization of the granodiorite there were multiple episodes of fluid expulsion. Above the marble layer at higher structural levels, magmatic fluids flowed both laterally and vertically, interacting with lithologies in a more pervasive manner. Values of delta O-18 for calcite in the vein skarns average 11.8% and pegmatite whole rock silicate delta O-18 values average 9.4%. Thus oxygen isotopic compositions are consistent with a magmatic origin for the skarn-forming fluids. Away from the vein skarns, values of delta O-18 for the capping marble range from 18.7 to 22.1% (avg. = 21%) and values of delta C-13 range from -3.8 to -3.0% (avg. = -3.4%). The high delta O-18 values provide evidence that the marble largely retained its premetamorphic isotopic composition, indicating that fluids from the granodiorite did not flow pervasively across the unit. Lithologies at higher structural levels show evidence of more pervasive interaction with magmatic fluids: forsterite-bearing calc-silicates have delta O-18 values down to 11.8% and coarse-grained vesuvianite- and wollastonite-bearing skarns have delta O-18 values of approximately 13%.

    To compare digital palpation with levator plate lift measured by endovaginal and transperineal dynamic sonography. Dynamic transperineal and endovaginal sonographic examinations were performed as part of multicompartmental pelvic floor functional assessment. Patients were instructed to perform Kegel contractions while a probe captured a video clip of levator plate movement at rest and during contraction in a 2-dimensional midsagittal posterior view. We measured the distance between the levator plate and the probe on endovaginal sonography as well as the distance between the levator plate and the gothic arch of the pubis on transperineal sonography. The change in diameter (lift) and levator plate lift ratio (lift/rest × 100) were calculated. Pelvic floor muscle strength was assessed by digital palpation and divided into functional and nonfunctional groups according to the Modified Oxford Scale. Mean differences in levator plate upward lift were compared by Modified Oxford Scale scores using Student t tests and analysis of variance. Seventy-four women were available for analysis. The mean age was 55 (SD, 11.9) years. When measured by vaginal dynamic sonography, mean lift and lift/rest ratio values increased with increasing Modified Oxford Scale score (analysis of variance, P= .09 and .04, respectively). When scores were categorized to represent nonfunctional (0-1) and functional (2-5) muscle strength groups, the mean lift (3.2 versus 4.6 mm; P = .03) and lift/rest ratio (13% versus 20%; P = .01) values were significantly higher in women with functional muscle strength. All patients with lift of 30% or greater detected by vaginal sonography had functional muscle strength. A greater levator plate lift ratio detected by dynamic endovaginal sonography was associated with higher muscle strength as determined by the Modified Oxford Scale. This novel measurement can be incorporated into sonographic evaluation of levator ani function. © 2015 by the American Institute of

    The National Vietnam Veterans Longitudinal Study (NVVLS) is the second assessment of a representative cohort of US veterans who served during the Vietnam War era, either in Vietnam or elsewhere. The cohort was initially surveyed in the National Vietnam Veterans Readjustment Study (NVVRS) from 1984 to 1988 to assess the prevalence, incidence, and effects of post-traumatic stress disorder (PTSD) and other post-war problems. The NVVLS sought to re-interview the cohort to assess the long-term course of PTSD. NVVLS data collection began July 3, 2012 and ended May 17, 2013, comprising three components: a mailed health questionnaire, a telephone health survey interview, and, for a probability sample of theater Veterans, a clinical diagnostic telephone interview administered by licensed psychologists. Excluding decedents, 78.8% completed the questionnaire and/or telephone survey, and 55.0% of selected living veterans participated in the clinical interview. This report provides a description of the NVVLS design and methods. Together, the NVVRS and NVVLS constitute a nationally representative longitudinal study of Vietnam veterans, and extend the NVVRS as a critical resource for scientific and policy analyses for Vietnam veterans, with policy relevance for Iraq and Afghanistan veterans.

    Veterans Affairs (VA) is expanding peer support. Research is limited on Veterans' perspective on benefits from peer services. We describe homeless Veteran perceptions of value and examine characteristics associated with benefit. From a sample of Veterans in a multisite randomized control trial, we studied addition of peers in VA Primary Care and homeless-oriented primary care clinics. We used qualitative methods to study the perceptions of peer services among a subsample of homeless Veterans. Quantitative methods were used to validate findings in both samples. Sixty-five percent of the subsample and 83% of the full sample benefited from a peer mentor. Participants who benefited had more peer visits and minutes of intervention (p<.05), were more likely to be minority, and were less likely to have posttraumatic stress disorder. The majority of Veteran participants in this study benefited from receiving peer mentor intervention. African American Veterans were more likely to benefit and Veterans with PTSD were less likely to benefit. Client endorsement of the peer's role influenced outcomes. © 2016 Wiley Periodicals, Inc.

  1. Impact of Supported Housing on Social Relationships Among Homeless Veterans.

    O'Connell, Maria J; Kasprow, Wesley J; Rosenheck, Robert A

    2017-02-01

    This study examined social network structure and function among a sample of 460 homeless veterans who participated in an experimental trial of the Housing and Urban Development-Veterans Affairs Supported Housing (HUD-VASH) program. Participants were randomly assigned to HUD-VASH (housing subsidies and case management), case management only, or standard care. Mixed-model longitudinal analysis was used to compare treatment groups on social network outcomes over 18 months. Veterans in HUD-VASH reported significantly greater increases in social support than veterans in the two other groups, as well as greater frequency of contacts, availability of tangible and emotional support, and satisfaction with nonkin relationships over time. These gains largely involved relationships with providers and other veterans encountered in treatment. Supported housing may play a pivotal role in fostering constructive new relationships with persons associated with service programs but may have a more limited impact on natural support networks.

    2015-12-01

    Among homeless veterans and those at risk of homelessness currently enrolled in Veterans Affairs (VA) health care, this study examined the proportion likely to become eligible for Medicaid in 2014 and their health needs. A total of 114,497 homeless and at-risk veterans were categorized into three groups: currently covered by Medicaid, likely to become eligible for Medicaid, and not likely. Seventy-eight percent of the sample was determined to be likely to become eligible for Medicaid in states that expand Medicaid. Compared with veterans not likely to become eligible for Medicaid, those likely to become eligible were less likely to have general medical and psychiatric conditions and to have a VA service-connected disability but more likely to have substance use disorders. Programs serving homeless and at-risk veterans should anticipate the potential interplay between VA health care and the expansion of Medicaid in states that implement the expansion.

  5. Match-bounded String Rewriting Systems

    Geser, Alfons; Hofbauer, Dieter; Waldmann, Johannes

    2003-01-01

    We introduce a new class of automated proof methods for the termination of rewriting systems on strings. The basis of all these methods is to show that rewriting preserves regular languages. To this end, letters are annotated with natural numbers, called match heights. If the minimal height of all positions in a redex is h+1 then every position in the reduct will get height h+1. In a match-bounded system, match heights are globally bounded. Using recent results on deleting systems, we prove that rewriting by a match-bounded system preserves regular languages. Hence it is decidable whether a given rewriting system has a given match bound. We also provide a sufficient criterion for the abence of a match-bound. The problem of existence of a match-bound is still open. Match-boundedness for all strings can be used as an automated criterion for termination, for match-bounded systems are terminating. This criterion can be strengthened by requiring match-boundedness only for a restricted set of strings, for instance the set of right hand sides of forward closures.

  6. The Formation and Evolution of Double Layers in Earth's Auroral Upward Current Region

    Science.gov (United States)

    Main, D. S.; Newman, D. L.; Ergun, R. E.

    2009-12-01

    Observations from the Fast Auroral SnapshoT (FAST) spacecraft indicate that a strong localized electric field often exists at the boundary separating the ionosphere from the auroral cavity in the upward current region. The localized electric field observed at the boundary usually has components that are both parallel and perpendicular to earth's magnetic field and therefore are said to be an “oblique” electric field. The boundary electric field has been modeled as an oblique BGK DL in prior efforts. In addition, FAST observations indicate that the auroral cavity has a density that is ~ 1/10 that of the ionosphere. We have used parameters derived from FAST to initialize a 1D3V (1 spatial dimension, 3 velocity dimensions) open boundary particle-in-cell simulation. We assume that a density cavity that is 1/10 - 1/20 the density of the ionosphere is initially present (as indicated by observations). However, unlike previous efforts, we do not assume that a self-consistent electric field is initially present. The initial plasma consists of anti-earthward O+ and H+ beams, hot magnetospheric H+ population, hot magnetospheric electron population and a cold dense electron population. We assume that the initial population is composed entirely of ionospheric species. At the two boundaries, plasma particles are injected based on the initial population with one key exception. The magnetospheric boundary does not include the cold electrons since observations indicate a lack of these species in the auroral cavity. We demonstrate that a DL readily forms out of the initial conditions at the interface of the dense and tenuous plasma. Furthermore the DL is quasi-stable for the entire simulation if the initial cold electrons are cold enough (~ 40 eV) and dense enough (0.3% of the total electron population). We also show that the oblique DLs are quasi-stable and also persist for the entire simulation. We find that to ensure the stability of the oblique DL, it is necessary to make

    In this work radial and axial flow regime development in adiabatic upward air-water two-phase flow in a vertical annulus has been investigated. Local flow regimes have been identified using conductivity probes and neural networks techniques. The inner and outer diameters of the annulus are 19.1 mm and 38.1 mm, respectively. The equivalent hydraulic diameter of the flow channel, D{sub H}, is 19.0 mm and the total length is 4.37 m. The flow regime map includes 1080 local flow regimes identifications in 72 flow conditions within a range of 0.01 m/s < < 30 m/s and 0.2 m/s < < 3.5 m/s where and are, respectively, superficial gas and liquid velocities. The local flow regime has been classified into four categories: bubbly, cap-slug, churn-turbulent and annular flows. In order to study the radial and axial development of flow regime the measurements have been performed at five radial locations. The three axial positions correspond to z/D{sub H} = 52, 149 and 230, where z represents the axial position. The flow regime indicator has been chosen as some statistical parameters of local bubble chord length distributions and self-organized neural networks have been used as mapping system. This information has been also used to compare the results given by the existing flow regime transition models. The local flow regime is characterized basically by the void fraction and bubble chord length. The radial development of flow regime shows partial and complete local flow regime combinations. The radial development is controlled by axial location and superficial liquid velocity. The radial flow regime transition is always initiated in the center of the flow channel and it is propagated towards the channel boundaries. The axial development of flow regime is observed in all the flow maps and it is governed by superficial liquid velocity and radial location. The prediction results of the models are compared for each flow regime transition.

  8. Female Veterans of Iraq and Afghanistan seeking care from VA specialized PTSD Programs: comparison with male veterans and female war zone veterans of previous eras.

    Differences in the characteristics and mental health needs of female veterans of the Iraq/Afghanistan war compared with those of veterans of other wars may have useful implications for VA program and treatment planning. Female veterans reporting service in the Iraq/Afghanistan war were compared with women reporting service in the Persian Gulf and Vietnam wars and to men reporting service in the Iraq/Afghanistan war. Subjects were drawn from VA administrative data on veterans who sought outpatient treatment from specialized posttraumatic stress disorder (PTSD) treatment programs. A series of analyses of covariance (ANCOVA) was used to control for program site and age. In general, Iraq/Afghanistan and Persian Gulf women had less severe psychopathology and more social supports than did Vietnam women. In turn, Iraq/Afghanistan women had less severe psychopathology than Persian Gulf women and were exposed to less sexual and noncombat nonsexual trauma than their Persian Gulf counterparts. Notable differences were also found between female and male veterans of the Iraq/Afghanistan war. Women had fewer interpersonal and economic supports, had greater exposure to different types of trauma, and had different levels of diverse types of pathology than their male counterparts. There appear to be sufficient differences within women reporting service in different war eras and between women and men receiving treatment in VA specialized treatment programs for PTSD that consideration should be given to program planning and design efforts that address these differences in every program treating female veterans reporting war zone service.

  11. Sound velocity bound and neutron stars.

    Science.gov (United States)

    Bedaque, Paulo; Steiner, Andrew W

    2015-01-23

    It has been conjectured that the velocity of sound in any medium is smaller than the velocity of light in vacuum divided by sqrt[3]. Simple arguments support this bound in nonrelativistic and/or weakly coupled theories. The bound has been demonstrated in several classes of strongly coupled theories with gravity duals and is saturated only in conformal theories. We point out that the existence of neutron stars with masses around two solar masses combined with the knowledge of the equation of state of hadronic matter at "low" densities is in strong tension with this bound.

  12. Lability of copper bound to humic acid

    2015-01-01

    Geochemical speciation models generally include the assumption that all metal bound to humic acid and fulvic acid (HA, FA) is labile. However, in the current study, we determined the presence of a soluble ‘non-labile’ Cu fraction bound to HA extracted from grassland and peat soils. This was quantified by determining isotopically-exchangeable Cu (E-value) and EDTA-extraction of HA-bound Cu, separated by size-exclusion chromatography (SEC) and assayed by coupled ICP-MS.

  13. Positivity bounds on double parton distributions

    Energy Technology Data Exchange (ETDEWEB)

    Diehl, Markus; Kasemets, Tomas

    2013-03-15

    Double hard scattering in proton-proton collisions is described in terms of double parton distributions. We derive bounds on these distributions that follow from their interpretation as probability densities, taking into account all possible spin correlations between two partons in an unpolarized proton. These bounds constrain the size of the polarized distributions and can for instance be used to set upper limits on the effects of spin correlations in double hard scattering. We show that the bounds are stable under leading-order DGLAP evolution to higher scales.

  14. Lower bound for the nuclear kinetic energy

    1985-06-27

    We argue that the kinetic energy of a many-fermion system is bounded from below by Kqsup(-2/3)A sup(5/3) / , with K = 0.565 where q is the number of spin states available to each particle and sup(1/2) is the root mean square radius of the single-particle density. A simple lower bound for the nuclear kinetic energy is found. Numerical values of the bound for several nuclei are shown, and a comparison with some self-consistent calculations and some pseudo-empirical values is made.

  15. Continuous bounded cohomology of locally compact groups

    CERN Document Server

    2001-01-01

    Recent research has repeatedly led to connections between important rigidity questions and bounded cohomology. However, the latter has remained by and large intractable. This monograph introduces the functorial study of the continuous bounded cohomology for topological groups, with coefficients in Banach modules. The powerful techniques of this more general theory have successfully solved a number of the original problems in bounded cohomology. As applications, one obtains, in particular, rigidity results for actions on the circle, for representations on complex hyperbolic spaces and on Teichmüller spaces. A special effort has been made to provide detailed proofs or references in quite some generality.

  16. Experimental detection of upward-going cosmic particles and consequences for correction of density radiography of volcanoes

    Muon tomography measures the flux of cosmic muons crossing geological bodies to determine their density. Three acquisitions with different sights of view were made at la soufrière de Guadeloupe. All of them show important density fluctuations and reveal the volcano phreatic system. The telescopes used to perform these measurements are exposed to noise fluxes with high intensities relative to the tiny flux of interest. We give experimental evidences ofa so far never described source of noise caused by a flux of upward-going particles. Data acquired on La soufrière of Guadeloupe and Mount Etna reveal that upward-going particles are detected only when the rear side of the telescope is exposed to a wide volume of atmosphere located below the altitude of the telescope and with a rock obstruction less than several tens of meters. Biases produced on density muon radiographies by upward-going fluxes are quantified and correction procedures are applied to radiographies of la soufrière.

  17. Mindfulness Training Promotes Upward Spirals of Positive Affect and Cognition: Multilevel and Autoregressive Latent Trajectory Modeling Analysis

    Directory of Open Access Journals (Sweden)

    Eric L Garland

    2015-02-01

    Full Text Available Recent theory suggests that positive psychological processes integral to health may be energized through the self-reinforcing dynamics of an upward spiral to counter emotion dysregulation. The present study examined positive emotion-cognition interactions among individuals in partial remission from depression who had been randomly assigned to treatment with mindfulness-based cognitive therapy (MBCT; n = 64 or a wait-list control condition (n = 66. We hypothesized that MBCT stimulates upward spirals by increasing positive affect and positive cognition. Experience sampling assessed changes in affect and cognition during 6 days before and after treatment, which were analyzed with a series of multilevel and autoregressive latent trajectory models. Findings suggest that MBCT was associated with significant increases in trait positive affect and momentary positive cognition, which were preserved through autoregressive and cross-lagged effects driven by global emotional tone. Findings suggest that daily positive affect and cognition are maintained by an upward spiral that might be promoted by mindfulness training.

  18. Openness to experience as a predictor and outcome of upward job changes into managerial and professional positions.

    Nieß, Christiane; Zacher, Hannes

    2015-01-01

    In industrial and organizational psychology, there is a long tradition of studying personality as an antecedent of work outcomes. Recently, however, scholars have suggested that personality characteristics may not only predict, but also change due to certain work experiences, a notion that is depicted in the dynamic developmental model (DDM) of personality and work. Upward job changes are an important part of employees' careers and career success in particular, and we argue that these career transitions can shape personality over time. In this study, we investigate the Big Five personality characteristics as both predictors and outcomes of upward job changes into managerial and professional positions. We tested our hypotheses by applying event history analyses and propensity score matching to a longitudinal dataset collected over five years from employees in Australia. Results indicated that participants' openness to experience not only predicted, but that changes in openness to experience also followed from upward job changes into managerial and professional positions. Our findings thus provide support for a dynamic perspective on personality characteristics in the context of work and careers.

    2016-04-01

    National Death Index data were examined to describe mortality patterns among older veterans who are homeless. Homelessness and health care records from the U.S. Department of Veterans Affairs were used to identify old (ages 55-59) and older (ages ≥60) veterans who were (N=4,475) or were not (N=20,071) homeless. Survival functions and causes of death of the two samples over an 11-year follow-up period were compared. Substantially more veterans who were homeless (34.9%) died compared with the control sample (18.2%). Veterans who were homeless were approximately 2.5 years younger at time of death compared with the control sample. Older veterans who were homeless had the lowest survival rate (58%). No disease category appeared to be critical in reducing survival time. Suicide was twice as frequent in the homeless (.4%) versus the control (.2%) sample. Older veterans who were homeless experienced excess mortality and increased suicide risk.

    2013-12-01

    We examined the empirical link between money mismanagement and subsequent homelessness among veterans. We used a random sample of Iraq and Afghanistan War era veterans from the National Post-Deployment Adjustment Survey in 2009-2011. Veterans were randomly selected from a roster of all US military service members in Operation Iraqi Freedom or Operation Enduring Freedom who were separated from active duty or in the Reserves/National Guard. Veterans (n = 1090) from 50 states and all military branches completed 2 waves of data collection 1 year apart (79% retention rate). Thirty percent reported money mismanagement (e.g., bouncing or forging a check, going over one's credit limit, falling victim to a money scam in the past year). Multivariate analysis revealed money mismanagement (odds ratio [OR] = 4.09, 95% CI = 1.87, 8.94) was associated with homelessness in the next year, as were arrest history (OR = 2.65, 95% CI = 1.33, 5.29), mental health diagnosis (OR = 2.59, 95% CI = 1.26, 5.33), and income (OR = 0.30, 95% CI = 0.13, 0.71). Money mismanagement, reported by a substantial number of veterans, was related to a higher rate of subsequent homelessness. The findings have implications for policymakers and clinicians, suggesting that financial education programs offered by the US Departments of Defense and Veterans Affairs may be targeted to effectively address veteran homelessness.

  3. Recruitment and retention of young adult veteran drinkers using Facebook.

    Directory of Open Access Journals (Sweden)

    Eric R Pedersen

    Full Text Available The objective of this study was to describe the feasibility of using Facebook as a platform to recruit and retain young adult veteran drinkers into an online-alcohol use intervention study. Facebook's wide accessibility and popularity among the age group that comprises the majority of veterans from the conflicts in Iraq and Afghanistan make it a compelling resource through which research can extend its reach to this otherwise hard-to-reach group. We developed a series of Facebook advertisement campaigns to reach veteran drinkers not specifically searching for alcohol treatment. In doing so, we recruited 793 valid veteran participants in approximately two weeks for an advertising cost of $4.53 per obtained participant. The study sample consisted primarily of male veterans, between 19 and 34 years of age, who were drinking at moderate to heavy levels. Although about half of the sample reported mental health comorbidity, few had received any mental health or substance use treatment in the past year. Facebook appears to be a valuable mechanism through which to recruit young veterans with unmet behavioral health needs, although more specific efforts may be needed to engage certain types of veterans after initial study enrollment.

    A small group of Gulf War veterans possess retained fragments of depleted uranium (DU) shrapnel, the long-term health consequences of which are undetermined. We evaluated the clinical health effects of DU exposure in Gulf War veterans compared with nonexposed Gulf War veterans. History and follow-up medical examination were performed on 29 exposed veterans and 38 nonexposed veterans. Outcome measures employed were urinary uranium determinations, clinical laboratory values, and psychiatric and neurocognitive assessment. DU-exposed Gulf War veterans with retained metal shrapnel fragments are excreting elevated levels of urinary uranium 7 years after first exposure (range 0.01-30.7 microg/g creatinine vs 0.01- 0.05 microg/g creatinine in the nonexposed). The persistence of the elevated urine uranium suggests on-going mobilization from a storage depot which results in a chronic systemic exposure. Adverse effects in the kidney, a presumed target organ, are not present at this time, though other effects are observed. Neurocognitive examinations demonstrated a statistical relationship between urine uranium levels and lowered performance on computerized tests assessing performance efficiency. Elevated urinary uranium was statistically related to a high prolactin level (>1.6 ng/ml; P=0.04). More than 7 years after first exposure, DU-exposed Gulf War veterans with retained metal fragments continue to excrete elevated concentrations of urinary uranium. Effects related to this are subtle perturbations in the reproductive and central nervous systems. Copyright 2000 Academic Press.

    Chronic disease risk may be high in people with multiple sclerosis (MS). Our objective was to identify chronic health conditions that may disproportionately affect male veterans with MS. We collected primary survey data for male veterans with MS (n = 1,142) in 2003 and 2004 and compared the data with 2003 Behavioral Risk Factor Surveillance System secondary data for comparison groups without MS (veteran population, n = 31,500; general population = 68,357). We compared disease prevalence by group and identified variables associated with chronic diseases in male veterans with MS. Overall, veterans with MS had a high prevalence of hypercholesterolemia (49%), hypertension (47%), diabetes (16%), coronary heart disease (11%), and stroke (7%). Overall and for the subset of people aged 50 years or older, diabetes, hypertension, hypercholesterolemia, coronary heart disease, and stroke were significantly more prevalent among male veterans with MS than among the general population. Diabetes, hypertension, hypercholesterolemia, and stroke were more prevalent overall among male veterans with MS than among the general veteran population; however, except for stroke, differences were not significant for the group aged 50 or older. Explanatory variables (eg, age, education, race) and dynamic associations between conditions (higher odds for each when ≥ 1 of the other conditions were present) for chronic disease in men with MS were similar to findings in the general population literature for select conditions. These findings raise awareness of chronic disease in a veteran cohort and help bridge a gap in the literature on chronic disease epidemiology in men with MS. We identified chronic disease priorities that may benefit from focused interventions to reduce disparities.

    2016-01-01

    We demonstrate that dark matter particles gravitationally bound to the Earth can induce a characteristic nuclear recoil signal at low energies in direct detection experiments. The new spectral feature we predict can provide the ultimate smoking gun for dark matter discovery for experiments...... with positive signal but unclear background. The new feature is universal, in that the ratio of bound over halo dark matter event rates at detectors is independent of the dark matter-nucleon cross section....

In this article, we report on two kinds of extensions for the Sason's results, namely a classical q-extension and a non-commutative(quantum) extension. Especially, we improve Sason's bound of the summation of the absolute value for the difference between two probability distributions, applying the parameter q of Tsallis entropy, under a certain assumption.

  11. Stable Bound States of Asymmetric Dark Matter

    The simplest renormalizable effective field theories with asymmetric dark matter bound states contain two additional gauge singlet fields one being the dark matter and the other a mediator particle that the dark matter annihilates into. We examine the physics of one such model with a Dirac fermion as the dark matter and a real scalar mediator. For a range of parameters the Yukawa coupling of the dark matter to the mediator gives rise to stable asymmetric dark matter bound states. We derive pr...

    Patients with subnormal serum vitamin B12 concentrations were tested for absorption of protein bound vitamin B12 and compared with controls. Absorption of the protein bound vitamin appeared to decrease with increasing age in healthy subjects. Differences between the result of this test and the result of the Schilling test in patients who had undergone gastric surgery were confirmed; such differences were also seen in some patients who had iron deficiency anaemia, an excessive alcohol intake, ...

  13. Dynamic optimization problems with bounded terminal conditions

    Bounded terminal conditions of nonlinear optimization problems are converted to equality terminal conditions via Valentine's device. In so doing, additional unknown parameters are introduced into the problem. The transformed problems can still be easily solved using the sequential gradient-restoration algorithm (SGRA) via a simple augmentation of the unknown parameter vector pi. Three example problems with bounded terminal conditions are solved to verify this technique.

    Research on veterans experiencing homelessness is predominantly focused on the US Department of Veterans Affairs setting, despite the fact that substantial numbers receive services from Health Care for the Homeless (HCH) clinics. We explored how HCH clinics identified veteran patients through a survey of administrators (49% response rate). The majority (98%) identified veterans but used varied language and approaches. Implementing a streamlined, culturally competent identification process is vital to collecting accurate data, connecting veterans with benefits, and informing treatment plans.

    2015-01-01

    Suicide is a major public health concern among U.S. veterans. Even when asked directly, veterans who die by suicide have been found to deny suicidal thoughts. Psychological assessment needs to go beyond the current risk factors and evaluate underlying factors that may increase suicide risk. In the present study, diagnostic interviews and self-report questionnaires were used to measure life meaning and suicidal ideation in a sample of 110 depressed veterans. Life meaning was significantly associated with suicidal ideation, even after accounting for depression and suicide history. Life meaning may be an important, previously ignored indicator of suicide risk.

    To assess health status among student veterans at a community college utilizing a partnership between a Veterans Affairs Medical Center and a community college. Student veterans at Cuyahoga Community College in Cleveland, Ohio, in January to April 2013. A health assessment survey was sent to 978 veteran students. Descriptive analyses to assess prevalence of clinical diagnoses and health behaviors were performed. Logistic regression analyses were performed to assess for independent predictors of functional limitations. 204 students participated in the survey (21% response rate). Self-reported depression and unhealthy behaviors were high. Physical and emotional limitations (45% and 35%, respectively), and pain interfering with work (42%) were reported. Logistic regression analyses confirmed the independent association of self-reported depression with functional limitation (odds ratio [OR] = 3.3, 95% confidence interval [CI] 1.4-7.8, p student veterans at a community college. A partnership between a Veterans Affairs Medical Center and a community college can be utilized to help understand the health needs of veteran students.
