    Full Text Available La biodiversidad costera tropical ha sido modulada por las tormentas y huracanes durante mucho tiempo y en nuestros días también está sujeta a severas presiones por actividades antropogénicas. El objetivo de esta revisión fue el compilar la información disponible para mejorar nuestra comprensión sobre el impacto de los huracanes y tratar de incentivar el establecimiento de monitoreos de los cambios del paisaje costero, ya que es la mejor forma de evaluar los impactos de estas tormentas. Aunque el impacto de los ciclones resiste generalizaciones amplias, se incluyen aspectos sobre dinámica histórica y asociación con eventos temporales y se detallan los efectos por resuspensión y traslado de sedimentos, impacto del oleaje y fragmentación de organismos del arrecife coralino. También se presentan brevemente algunos efectos sobre tortugas marinas y bosques costerosTropical coastal biodiversity has been modulated by tropical storms during a long time and it is currently facing a heavy human impact. The purpose of this review is to compile the available information to improve our understanding of hurricane impacts and to promote the establishment of coastal landscape monitoring, because that is the best way to assess these impacts. Although generalizations on hurricane effects are elusive, some historical dynamics and temporal relationships are included and some details are presented on the impacts by resuspension and movement of sediments, storm waves, and breaking off of coral reef organisms. Some effects on marine turtles and coastal forests are also briefly pointed out

    Full Text Available En arrecifes coralinos del suroeste de Cuba, se evaluaron los impactos de la inusitada frecuencia e intensidad de huracanes entre el 2001 y el 2007, y de las enfermedades de corales, ambos factores asociados al cambio climático. En las crestas arrecifales, la reducción de la cobertura de coral duro vivo varió de nula a 21%, mientras que la reducción del diámetro máximo promedio de los corales varió de 16 a 40 cm. En los arrecifes frontales, la reducción de la cobertura de coral varió de nula a 14%, mientras que la reducción del diámetro máximo promedio varió de nula a 26 cm. Sin embargo, en todos los sitios se observaron grandes cambios en el predominio numérico de las especies. En las crestas, este se desplazó de  Acropora palmata y otros corales duros hacia Millepora complanata, Porites astreoides o Acropora prolifera. En los arrecifes frontales, el cambio ocurrió de la dominancia de Montastraea annularis (complejo de especies, Diploria strigosa y Agaricia agaricites a la de P. astreoides o Siderastrea siderea. Con esos cambios, las crestas están perdiendo efectividad como refugios y como disipadoras del oleaje, a causa de la reducción de complejidad estructural. La densidad del erizo Diadema antillarum se mantuvo insignificante y sin cambio en el sur del Golfo de Batabanó, mientras que se incrementó de manera importante en la cresta de Faro Cazones. Los porcentajes de mortalidad reciente y de incidencia de enfermedades de corales se mantuvieron bajos, lo que sugiere una influencia dominante de los huracanes en la condición de los arrecifes coralinos evaluados. In coral reefs of southwestern Cuba, we assessed the impacts from unprecedented frequent and intense hurricanes during the period 2001-2007, and from coral diseases, which are both factors considered to be associated with climate change.. At the reef crests, live hard coral cover reduction varied from null to 21%, while maximum average coral diameter reduction

  1. Break-up of New Orleans Households after Hurricane Katrina

    Rendall, Michael S.

    2011-01-01

    Theory and evidence on disaster-induced population displacement have focused on individual and population-subgroup characteristics. Less is known about impacts on households. I estimate excess incidence of household break-up due to Hurricane Katrina by comparing a probability sample of pre-Katrina New Orleans resident adult household heads and non–household heads (N = 242), traced just over a year later, with a matched sample from a nationally representative survey over an equivalent period. One in three among all adult non–household heads, and one in two among adult children of household heads, had separated from the household head 1 year post-Katrina. These rates were, respectively, 2.2 and 2.7 times higher than national rates. A 50% higher prevalence of adult children living with parents in pre-Katrina New Orleans than nationally increased the hurricane’s impact on household break-up. Attention to living arrangements as a dimension of social vulnerability in disaster recovery is suggested. PMID:21709733

    2011-06-01

    We examined patterns and correlates of speed of recovery of estimated posttraumatic stress disorder (PTSD) among people who developed PTSD in the wake of Hurricane Katrina. A probability sample of prehurricane residents of areas affected by Hurricane Katrina was administered a telephone survey 7-19 months following the hurricane and again 24-27 months posthurricane. The baseline survey assessed PTSD using a validated screening scale and assessed a number of hypothesized predictors of PTSD recovery that included sociodemographics, prehurricane history of psychopathology, hurricane-related stressors, social support, and social competence. Exposure to posthurricane stressors and course of estimated PTSD were assessed in a follow-up interview. An estimated 17.1% of respondents had a history of estimated hurricane-related PTSD at baseline and 29.2% by the follow-up survey. Of the respondents who developed estimated hurricane-related PTSD, 39.0% recovered by the time of the follow-up survey with a mean duration of 16.5 months. Predictors of slow recovery included exposure to a life-threatening situation, hurricane-related housing adversity, and high income. Other sociodemographics, history of psychopathology, social support, social competence, and posthurricane stressors were unrelated to recovery from estimated PTSD. The majority of adults who developed estimated PTSD after Hurricane Katrina did not recover within 18-27 months. Delayed onset was common. Findings document the importance of initial trauma exposure severity in predicting course of illness and suggest that pre- and posttrauma factors typically associated with course of estimated PTSD did not influence recovery following Hurricane Katrina. © 2011 Wiley-Liss, Inc.

  6. A comparison of the nursing home evacuation experience between hurricanes katrina (2005) and gustav (2008).

    Blanchard, Gary; Dosa, David

    2009-11-01

    One of the tragic legacies of Hurricane Katrina was the loss of life among Louisiana (LA) nursing home (NH) residents. Katrina revealed a staggering lack of emergency preparation and understanding of how to safely evacuate frail populations. Three years later, LA braced for Hurricane Gustav, a storm heralded to rival Katrina's power. Although its magnitude of destruction ultimately paled to Katrina, the warnings and predicted path preceding Gustav yielded a process of NH evacuations similar to Katrina. The goal of this article was to ascertain whether NH administrative directors (ADs) felt more prepared to evacuate before Gustav. In 2006, Dosa et al(5) (J Am Med Dir Assoc, 3/07), interviewed 20 NH ADs by qualitative telephone survey to evaluate their lessons learned from Katrina. Administrators at these 20 participating nursing homes were contacted and asked to participate in a follow-up survey to compare hurricane preparedness between 2005 and 2008. Specifically, ADs were asked if they evacuated before Gustav, their destination, and about logistical issues with evacuation (eg, transportation, injuries). ADs were asked to rate their confidence with state assistance, hurricane transportation, and evacuation preparedness on a 10-point scale (10=most confident) and compare their preparedness to Katrina. Sixteen of the 20 NHs that participated in 2006 agreed to be surveyed-11 of whom held the same position before Katrina. Unlike Katrina, when only 45% evacuated before the storm, all 16 NHs evacuated before Gustav (56% to another NH and 46% to a church, gym, college, or other facility). Overall, ADs rated their confidence in preparedness for Gustav as a mean of 8.3 (range 5 to 10) compared with a mean of 5.4 (range 3 to 8) for Katrina, a 54% improvement. Of the 11 ADs employed pre-Katrina, 73% reported improved collaboration with the state and 55% noted improved transportation. Nevertheless, 7 ADs noted significant logistical problems during evacuation (mostly

  8. Race differences in depression vulnerability following Hurricane Katrina.

    Ali, Jeanelle S; Farrell, Amy S; Alexander, Adam C; Forde, David R; Stockton, Michelle; Ward, Kenneth D

    2017-05-01

    This study investigated whether racial disparities in depression were present after Hurricane Katrina. Data were gathered from 932 New Orleans residents who were present when Hurricane Katrina struck, and who returned to New Orleans the following year. Multiple logistic regression models evaluated racial differences in screening positive for depression (a score ≥16 on the Center for Epidemiologic Studies Depression Scale), and explored whether differential vulnerability (prehurricane physical and mental health functioning and education level), differential exposure to hurricane-related stressors, and loss of social support moderated and/or reduced the association of race with depression. A univariate logistic regression analysis showed the odds for screening positive for depression were 86% higher for African Americans than for Caucasians (odds ratio [OR] = 1.86 [1.28-2.71], p = .0012). However, after controlling simultaneously for sociodemographic characteristics, preexisting vulnerabilities, social support, and trauma-specific factors, race was no longer a significant correlate for screening positive for depression (OR = 1.54 [0.95-2.48], p = .0771). The racial disparity in postdisaster depression seems to be confounded by sociodemographic characteristics, preexisting vulnerabilities, social support, and trauma-specific factors. Nonetheless, even after adjusting for these factors, there was a nonsignificant trend effect for race, which could suggest race played an important role in depression outcomes following Hurricane Katrina. Future studies should examine these associations prospectively, using stronger assessments for depression, and incorporate measures for discrimination and segregation, to further understand possible racial disparities in depression after Hurricane Katrina.

  10. Hurricane Katrina Wind Investigation Report

    2007-08-15

    This investigation of roof damage caused by Hurricane Katrina is a joint effort of the Roofing Industry Committee on Weather Issues, Inc. (RICOWI) and the Oak Ridge National Laboratory/U.S. Department of Energy (ORNL/DOE). The Wind Investigation Program (WIP) was initiated in 1996. Hurricane damage that met the criteria of a major windstorm event did not materialize until Hurricanes Charley and Ivan occurred in August 2004. Hurricane Katrina presented a third opportunity for a wind damage investigation in August 29, 2005. The major objectives of the WIP are as follows: (1) to investigate the field performance of roofing assemblies after major wind events; (2) to factually describe roofing assembly performance and modes of failure; and (3) to formally report results of the investigations and damage modes for substantial wind speeds The goal of the WIP is to perform unbiased, detailed investigations by credible personnel from the roofing industry, the insurance industry, and academia. Data from these investigations will, it is hoped, lead to overall improvement in roofing products, systems, roofing application, and durability and a reduction in losses, which may lead to lower overall costs to the public. This report documents the results of an extensive and well-planned investigative effort. The following program changes were implemented as a result of the lessons learned during the Hurricane Charley and Ivan investigations: (1) A logistics team was deployed to damage areas immediately following landfall; (2) Aerial surveillance--imperative to target wind damage areas--was conducted; (3) Investigation teams were in place within 8 days; (4) Teams collected more detailed data; and (5) Teams took improved photographs and completed more detailed photo logs. Participating associations reviewed the results and lessons learned from the previous investigations and many have taken the following actions: (1) Moved forward with recommendations for new installation procedures

    Since the catastrophic flooding of New Orleans due to Hurricane Katrina in 2005, the city's hurricane protection system has been improved to provide protection against a hurricane load with a 1/100 per year exceedance frequency. This paper investigates the risk to life in post-Katrina New Orleans. In a flood risk analysis the probabilities and consequences of various flood scenarios have been analyzed for the central area of the city (the metro bowl) to give a preliminary estimate of the risk to life in the post-Katrina situation. A two-dimensional hydrodynamic model has been used to simulate flood characteristics of various breaches. The model for estimation of fatality rates is based on the loss of life data for Hurricane Katrina. Results indicate that - depending on the flood scenario - the estimated loss of life in case of flooding ranges from about 100 to nearly 500, with the highest life loss due to breaching of the river levees leading to large flood depths. The probability and consequence estimates are combined to determine the individual risk and societal risk for New Orleans. When compared to risks of other large-scale engineering systems (e.g., other flood prone areas, dams and the nuclear sector) and acceptable risk criteria found in literature, the risks for the metro bowl are found to be relatively high. Thus, despite major improvements to the flood protection system, the flood risk to life of post-Katrina New Orleans is still expected to be significant. Indicative effects of reduction strategies on the risk level are discussed as a basis for further evaluation and discussion.

    Hurricane Katrina devastated New Orleans and its suburbs on Monday August 29^th, 2005. The previous Friday morning, August 26, the National Hurricane Center indicated that Katrina was a Category One Hurricane, which was expected to hit Florida. By Friday afternoon, it had changed its course, and neither the city nor Xavier University was prepared for this unexpected turn in the hurricane's path. The university had 6 to 7 ft of water in every building and Xavier was closed for four months. Students and university personnel that were unable to evacuate were trapped on campus and transportation out of the city became a logistical nightmare. Email and all electronic systems were unavailable for at least a month, and all cell phones with a 504 area code stopped working. For the Department, the most immediate problem was locating faculty and students. Xavier created a list of faculty and their new email addresses and began coordinating with faculty. Xavier created a web page with advice for students, and the chair of the department created a separate blog with contact information for students. The early lack of a clear method of communication made worse the confusion and dismay among the faculty on such issues as when the university would reopen, whether the faculty would be retained, whether they should seek temporary (or permanent) employment elsewhere, etc. With the vision and determination of President Dr. Francis, Xavier was able to reopen the university in January and ran a full academic year from January through August. Since Katrina, the university has asked every department and unit to prepare emergency preparedness plans. Each department has been asked to collect e-mail addresses (non-Xavier), cell phone numbers and out of town contact information. The University also established an emergency website to communicate. All faculty have been asked to prepare to teach classes electronically via Black board or the web. Questions remain about the longer term issues of

    Existing research suggests that walkable environments are protective against weight gain, while sprawling neighborhoods may pose health risks. Using prospective data on displaced Hurricane Katrina survivors, we provide the first natural experimental data on sprawl and body mass index (BMI). The analysis uses prospectively collected pre- (2003-2005) and post-hurricane (2006-2007) data from the Resilience in Survivors of Katrina (RISK) project on 280 displaced Hurricane Katrina survivors who had little control over their neighborhood placement immediately after the disaster. The county sprawl index, a standardized measure of built environment, was used to predict BMI at follow-up, adjusted for baseline BMI and sprawl; hurricane-related trauma; and demographic and economic characteristics. Respondents from 8 New Orleans-area counties were dispersed to 76 counties post-Katrina. Sprawl increased by an average of 1.5 standard deviations (30 points) on the county sprawl index. Each one point increase in sprawl was associated with approximately .05kg/m(2) higher BMI in unadjusted models (95%CI: .01-.08), and the relationship was not attenuated after covariate adjustment. We find a robust association between residence in a sprawling county and higher BMI unlikely to be caused by self-selection into neighborhoods, suggesting that the built environment may foster changes in weight.

    Hurricane Katrina provided an opportunity to observe the public health and medical care response system in practice and provided vital lessons about identifying and learning critical response measures as well as about ineffective investments of time and effort. The Southwest Center for Public Health Preparedness (SWCPHP) response team, while working among evacuees housed at Reliant Park in Houston, Texas, made a number of observations related to environmental public health. This summary reports firsthand observations which are, to a great extent, supported by the Federal Response to Hurricane Katrina: Lessons Learned report, and it provides a contextual backdrop for improvement in the areas of volunteer and citizen preparedness training and education. Katrina provided an opportunity to see public health in a highly stressed practice setting and to identify and reinforce the fundamental tenets of public health with which all individuals responding to an event should be familiar. Knowledge gained from Katrina should be integrated into future efforts related to disaster response planning; specifically, it is imperative that volunteers receive standardized training in the areas of incident command systems (ICS), basic hygiene, transmission of disease, and food and water safety principles.

    In August 2005, New Orleans was hit by Hurricane Katrina, the costliest natural disaster in US history. Previous studies have shown an increase in acute myocardial infarction (AMI) in the immediate hours to weeks after natural disasters. The goals of our study were to detect any long-term increase in the incidence of AMI after Katrina and to investigate any pertinent contributing factors. This was a single-center retrospective cohort observational study. Patients admitted with AMI to Tulane Health Sciences Center hospital in the 2 years before Katrina and in the 2 years after the hospital reopened (5 months after Katrina) were identified from hospital records. The 2 groups (pre- and post-Katrina) were compared for prespecified demographic and clinical data. In the post-Katrina group, there were 246 admissions for AMI, out of a total census of 11,282 patients (2.18%), as compared with 150 AMI admissions out of a total of 21,229 patients (0.71%) in the pre-Katrina group (P affected (P housing (P = 0.003). The role of chronic stress in the pathogenesis of AMI is poorly understood, especially in the aftermath of natural disasters. Our data suggest that Katrina was associated with prolonged loss of employment and insurance, decreased access to preventive health services, and an increased incidence of AMI. In addition, it appears that chronic stress after a natural disaster can be associated with tobacco abuse and medication and therapeutic noncompliance. We found a 3-fold increased incidence of AMI more than 2 years after Hurricane Katrina. Even allowing for the loss of some local hospitals after the disaster, this represents a significant change in overall health of the study population and supports the need for further study into the health effects of chronic stress.

    Claims of environmental injustice, human neglect, and racism dominated the popular and academic literature after Hurricane Katrina struck the United States in August 2005. A systematic analysis of environmental injustice from the perspective of the survivors remains scanty or nonexistent. This paper presents, therefore, a systematic empirical analysis of the key determinants of Katrina-induced environmental injustice attitudes among survivors in severely affected parishes (counties) in Louisiana and Mississippi three years into the recovery process. Statistical models based on a random sample of survivors were estimated, with the results revealing significant predictors such as age, children in household under 18, education, homeownership, and race. The results further indicate that African-Americans were more likely to perceive environmental injustice following Katrina than their white counterparts. Indeed, the investigation reveals that there are substantial racial gaps in measures of environmental injustice. The theoretical, methodological, and applied policy implications of these findings are discussed. © 2017 The Author(s). Disasters © Overseas Development Institute, 2017.

  5. Katrina in Historical Context: Environment and Migration in the U.S.

    Gutmann, Myron P; Field, Vincenzo

    2010-01-01

    The massive publicity surrounding the exodus of residents from New Orleans spurred by Hurricane Katrina has encouraged interest in the ways that past migration in the U.S. has been shaped by environmental factors. So has Timothy Egan's exciting book, The Worst Hard Time: The Untold Story of those who survived the Great American Dust Bowl. This paper places those dramatic stories into a much less exciting context, demonstrating that the kinds of environmental factors exemplified by Katrina and the Dust Bowl are dwarfed in importance and frequency by the other ways that environment has both impeded and assisted the forces of migration. We accomplish this goal by enumerating four types of environmental influence on migration in the U.S.: 1) environmental calamities, including floods, hurricanes, earthquakes, and tornadoes, 2) environmental hardships and their obverse, short-term environmental benefits, including both drought and short periods of favorable weather, 3) environmental amenities, including warmth, sun, and proximity to water or mountains, and 4) environmental barriers and their management, including heat, air conditioning, flood control, drainage, and irrigation. In U.S. history, all four of these have driven migration flows in one direction or another. Placing Katrina into this historical context is an important task, both because the environmental calamities of which Katrina is an example are relatively rare and have not had a wide impact, and because focusing on them defers interest from the other kinds of environmental impacts, whose effect on migration may have been stronger and more persistent, though less dramatic.

    Thirteen years after Hurricane Andrew struck Homestead, FL, Hurricane Katrina devastated the Gulf Coast of Mississippi, Alabama, and southeastern Louisiana. Along with all its destruction, the term "catastrophic" was redefined. This article extends the literature on these hurricanes by providing a macrolevel analysis of The Governor's Disaster Planning and Response Review Committee Final Report from Hurricane Andrew and three federal after-action reports from Hurricane Katrina, as well as a cursory review of relevant literature. Results provide evidence that previous lessons have not been learned or institutionalized with many recommendations being repeated or modified. This article concludes with a discussion of these lessons, as well as new issues arising during Hurricane Katrina.

    We use data from the monthly Current Population Survey to examine the short- and longer-term effects of Hurricane Katrina on the labor market outcomes of prime-age individuals in the most affected states--Alabama, Florida, Louisiana, and Mississippi--and for evacuees in any state. We focus on rates of labor force participation, employment, and unemployment, and we extend prior research by also examining rates of self-employment. With the exception of Mississippi, employment and unemployment one year after the hurricane were at similar rates as the end of 2003. This aggregate pattern of labor market shock and recovery has been observed for other disasters but masks important differences among subgroups. Those evacuated from their residences, even temporarily, were a harder-hit group, and evacuees who had yet to return to their pre-Katrina state up to one year later were hit especially hard; these findings hold even after controlling for differences in observable characteristics. We also find evidence of an important role for self-employment as part of post-disaster labor market recovery, especially for evacuees who did not return. This may result from poor job prospects in the wage and salary sector or new opportunities for starting businesses in the wake of Katrina.

    Full Text Available The life cycle of Hurricane Katrina (2005 was simulated using three different modeling systems of Weather Research and Forecasting (WRF mesoscale model. These are, HWRF (Hurricane WRF designed specifically for hurricane studies and WRF model with two different dynamic cores as the Advanced Research WRF (ARW model and the Non-hydrostatic Mesoscale Model (NMM. The WRF model was developed and sourced from National Center for Atmospheric Research (NCAR, incorporating the advances in atmospheric simulation system suitable for a broad range of applications. The HWRF modeling system was developed at the National Centers for Environmental Prediction (NCEP based on the NMM dynamic core and the physical parameterization schemes specially designed for tropics. A case study of Hurricane Katrina was chosen as it is one of the intense hurricanes that caused severe destruction along the Gulf Coast from central Florida to Texas. ARW, NMM and HWRF models were designed to have two-way interactive nested domains with 27 and 9 km resolutions. The three different models used in this study were integrated for three days starting from 0000 UTC of 27 August 2005 to capture the landfall of hurricane Katrina on 29 August. The initial and time varying lateral boundary conditions were taken from NCEP global FNL (final analysis data available at 1 degree resolution for ARW and NMM models and from NCEP GFS data at 0.5 degree resolution for HWRF model. The results show that the models simulated the intensification of Hurricane Katrina and the landfall on 29 August 2005 agreeing with the observations. Results from these experiments highlight the superior performance of HWRF model over ARW and NMM models in predicting the track and intensification of Hurricane Katrina.

    This study examines prevalence of respiratory conditions in New Orleans-area restoration workers after Hurricane Katrina. Between 2007 and 2010, spirometry and respiratory health and occupational questionnaire were administered to 791 New Orleans-area adults who mostly worked in the building construction and maintenance trades or custodial services. The associations between restoration work hours and lung function and prevalence of respiratory symptoms were examined by multiple linear regression, χ², or multiple logistic regression. 74% of participants performed post-Katrina restoration work (median time: 620 hours). Symptoms reported include episodes of transient fever/cough (29%), sinus symptoms (48%), pneumonia (3.7%), and new onset asthma (4.5%). Prevalence rate ratios for post-Katrina sinus symptoms (PRR = 1.3; CI: 1.1, 1.7) and fever and cough (PRR = 1.7; CI: 1.3, 2.4) were significantly elevated overall for those who did restoration work and prevalence increased with restoration work hours. Prevalence rate ratios with restoration work were also elevated for new onset asthma (PRR = 2.2; CI: 0.8, 6.2) and pneumonia (PRR = 1.3; CI: 0.5, 3.2) but were not statistically significant. Overall, lung function was slightly depressed but was not significantly different between those with and without restoration work exposure. Post-Katrina restoration work is associated with moderate adverse effects on respiratory health, including sinusitis and toxic pneumonitis.

    Tropical cyclones that enter or form in the Gulf of Mexico generate storm surge and large waves that impact low-lying coastlines along the Gulf Coast. The Chandeleur Islands, located 161. km east of New Orleans, Louisiana, have endured numerous hurricanes that have passed nearby. Hurricane Katrina (landfall near Waveland MS, 29 Aug 2005) caused dramatic changes to the island elevation and shape. In this paper the predictability of hurricane-induced barrier island erosion and accretion is evaluated using a coupled hydrodynamic and morphodynamic model known as XBeach. Pre- and post-storm island topography was surveyed with an airborne lidar system. Numerical simulations utilized realistic surge and wave conditions determined from larger-scale hydrodynamic models. Simulations included model sensitivity tests with varying grid size and temporal resolutions. Model-predicted bathymetry/topography and post-storm survey data both showed similar patterns of island erosion, such as increased dissection by channels. However, the model under predicted the magnitude of erosion. Potential causes for under prediction include (1) errors in the initial conditions (the initial bathymetry/topography was measured three years prior to Katrina), (2) errors in the forcing conditions (a result of our omission of storms prior to Katrina and/or errors in Katrina storm conditions), and/or (3) physical processes that were omitted from the model (e.g., inclusion of sediment variations and bio-physical processes). ?? 2010.

    To examine how the recovery following Hurricane Katrina affected pregnancy outcomes. 308 New Orleans area pregnant women were interviewed 5-7 years after Hurricane Katrina about their exposure to the disaster (danger, damage, and injury); current disruption; and perceptions of recovery. Birthweight, gestational age, birth length, and head circumference were examined in linear models, and low birthweight (<2500 g) and preterm birth (<37 weeks) in logistic models, with adjustment for confounders. Associations were found between experiencing damage during Katrina and birthweight (adjusted beta for high exposure = -158 g) and between injury and gestational age (adjusted beta = -0.5 days). Of the indicators of recovery experience, most consistently associated with worsened birth outcomes was worry that another hurricane would hit the region (adjusted beta for birthweight: -112 g, p = 0.08; gestational age: -3.2 days, p = 0.02; birth length: -0.65 cm, p = 0.06). Natural disaster may have long-term effects on pregnancy outcomes. Alternately, women who are most vulnerable to disaster may be also vulnerable to poor pregnancy outcome.

    2007-01-01

    The tragedy that was unleashed when hurricane Katrina hit the United States southern coast and most particularly New Orleans is still being examined. Regardless of the allocation of blame for the response, or lack thereof, several very important components of what needs to be included in effective strategic, management, and response plans were revealed in the aftermath. The first tenet is to be sure not to make the problem worse. In other words, the goal is to prevent emergencies from becoming a disaster that subsequently grows to a catastrophe. Essential components that need to be addressed start with protection and rescue of affected people. Several characteristics of an effective strategic plan that will address saving lives include leadership, continuity of government and business, effective communications, adequate evacuation plans and security of electronic infrastructure. Katrina analysis confirms that the process to integrate all the components is too complex to be accomplished ad hoc. This presentation will outline objective methodology to successfully integrate the various facets that comprise an effective strategic plan, management plan, and tactical plans.(author)

Results indicated significant contamination of As and V and non-significant contamination of Cd, Cr, Cu, Hg and Pb at most sampling sites. Compared to the reported EPA Region 6 soil background inorganic levels, except As, the concentrations of other six elements had greatly increased throughout the studied area; St. Bernard Parish and Plaquemines Parish showed greater contamination than other regions.

    Spruce, Joseph; McKellip, Rodney

    2006-01-01

    Hurricane Katrina hit southeastern Louisiana and the Mississippi Gulf Coast as a Category 3 hurricane with storm surges as high as 9 m. Katrina devastated several coastal towns by destroying or severely damaging hundreds of homes. Several Federal agencies are assessing storm impacts and assisting recovery using high-spatial-resolution remotely sensed data from satellite and airborne platforms. High-quality IKONOS satellite imagery was collected on September 2, 2005, over southwestern Mississippi. Pan-sharpened IKONOS multispectral data and ERDAS IMAGINE software were used to classify post-storm land cover for coastal Hancock and Harrison Counties. This classification included a storm debris category of interest to FEMA for disaster mitigation. The classification resulted from combining traditional unsupervised and supervised classification techniques. Higher spatial resolution aerial and handheld photography were used as reference data. Results suggest that traditional classification techniques and IKONOS data can map wood-dominated storm debris in open areas if relevant training areas are used to develop the unsupervised classification signatures. IKONOS data also enabled other hurricane damage assessment, such as flood-deposited mud on lawns and vegetation foliage loss from the storm. IKONOS data has also aided regional Katrina vegetation damage surveys from multidate Land Remote Sensing Satellite and Moderate Resolution Imaging Spectroradiometer data.

  6. Katrina's Lessons in California: Social and Political Trajectories of Flood Management in the Sacramento River Watershed since 2005

    Science.gov (United States)

    Comby, E.; Le Lay, Y. F.; Piegay, H.

    2017-12-01

    Over the last decade, major changes have occurred in the way that environments are managed. They can be linked with external or internal events which may shape public perception. An external event can reveal a forgotten risk and create a social problem (Hilgartner et Bosk 1988). Following the Advocacy Coalition Framework (Sabatier 1988), we studied the role of Hurricane Katrina in flood management in California from 2005 to 2013. How do policies intend to increase the city's resilience? We compared different flood policies of the Sacramento River from 2005 to 2013, by combining field observations with a principal dataset of 340 regional newspaper items (Sacramento Bee). Media coverage was analyzed using content, quotation, and textometry as well as GIS. We underlined temporal variability in public perceptions towards floods. Some planning choices (such as levees) became controversial, while journalists praised weirs, bypasses, and dams. However, Katrina does not seem to have a real impact on urban sprawl strategies in three Sacramento neighborhoods (Fig.1). We analyzed also the limits of the comparison between New Orleans and Sacramento. Dialog between stakeholders existed in space and time between here (California) and elsewhere (Louisiana), present (post-2005) and past (Katrina catastrophe), and risk and disaster. Katrina was a national scandal with political announcements. However, flood policy was developed first at a regional and then local scales. After Katrina awareness, conflicts appear: some California residents refuse to have a policy linked to Katrina applied to them. We underlined that different stakeholders became prominent: it may be useless to tackle with only one institution. Some institutions had an integrated river management, while others kept a traditional risk management. We assessed the changes in river management while using discourse to understand the (potential) shift in human-river relationships from risk management to integrated river

    Full Text Available Abstract Living through hurricane Katrina and its aftermath and reflecting on these experiences from technical and non-technical standpoints has led me to reconsider my thoughts and philosophy on engineering education. I present three ideas regarding engineering education pedagogy that I believe will prepare future engineers for problem-solving in an increasingly complex world. They are (1 we must practice radical (to the root engineering, (2 we must illustrate connections between engineering and public policy, and (3 we will join the charge to find sustainable solutions to problems. Ideas for bringing each of these concepts into engineering curricula through methods such as case study, practicing broad information gathering and data interpretation, and other methods inside and outside the classroom, are discussed. I believe that the consequences of not considering the root issues of problems to be solved, and of not including policy and sustainability considerations when problems to be solved are framed will lead our profession toward well meaning but insufficient utility. Hurricane Katrina convinced me that we must do better as educators to prepare our students for engineering for a sustainable world.

    2009-04-01

    The damage inflicted by hurricanes Katrina and Rita to the Gulf-of-Mexico's (GoM) oil and gas production, both onshore and offshore, has shown the proneness of industry to Natech accidents (natural hazard-triggered hazardous-materials releases). In order to contribute towards a better understanding of Natech events, we assessed the damage to and hazardous-materials releases from offshore oil and natural-gas platforms and pipelines induced by hurricanes Katrina and Rita. Data was obtained through a review of published literature and interviews with government officials and industry representatives from the affected region. We also reviewed over 60,000 records of reported hazardous-materials releases from the National Response Center's (NRC) database to identify and analyze the hazardous-materials releases directly attributed to offshore oil and gas platforms and pipelines affected by the two hurricanes. Our results show that hurricanes Katrina and Rita destroyed at least 113 platforms, and severely damaged at least 53 others. Sixty percent of the facilities destroyed were built 30 years ago or more prior to the adoption of the more stringent design standards that went into effect after 1977. The storms also destroyed 5 drilling rigs and severely damaged 19 mobile offshore drilling units (MODUs). Some 19 MODUs lost their moorings and became adrift during the storms which not only posed a danger to existing facilities but the dragging anchors also damaged pipelines and other infrastructure. Structural damage to platforms included toppling of sections, and tilting or leaning of platforms. Possible causes for failure of structural and non-structural components of platforms included loading caused by wave inundation of the deck. Failure of rigs attached to platforms was also observed resulting in significant damage to the platform or adjacent infrastructure, as well as damage to equipment, living quarters and helipads. The failures are attributable to tie-down components

  17. The location of displaced New Orleans residents in the year after Hurricane Katrina.

    2014-06-01

    Using individual data from the restricted version of the American Community Survey, we examined the displacement locations of pre-Hurricane Katrina adult residents of New Orleans in the year after the hurricane. More than one-half (53 %) of adults had returned to-or remained in-the New Orleans metropolitan area, with just under one-third of the total returning to the dwelling in which they resided prior to Hurricane Katrina. Among the remainder, Texas was the leading location of displaced residents, with almost 40 % of those living away from the metropolitan area (18 % of the total), followed by other locations in Louisiana (12 %), the South region of the United States other than Louisiana and Texas (12 %), and elsewhere in the United States (5 %). Black adults were considerably more likely than nonblack adults to be living elsewhere in Louisiana, in Texas, and elsewhere in the South. The observed race disparity was not accounted for by any of the demographic or socioeconomic covariates in the multinomial logistic regression models. Consistent with hypothesized effects, we found that following Hurricane Katrina, young adults (aged 25-39) were more likely to move further away from New Orleans and that adults born outside Louisiana were substantially more likely to have relocated away from the state.

  19. A Tsunami Ball Approach to Storm Surge and Inundation: Application to Hurricane Katrina, 2005

    Directory of Open Access Journals (Sweden)

    Steven N. Ward

    2009-01-01

    Full Text Available Most analyses of storm surge and inundation solve equations of continuity and momentum on fixed finite-difference/finite-element meshes. I develop a completely new approach that uses a momentum equation to accelerate bits or balls of water over variable depth topography. The thickness of the water column at any point equals the volume density of balls there. In addition to being more intuitive than traditional methods, the tsunami ball approach has several advantages. (a By tracking water balls of fixed volume, the continuity equation is satisfied automatically and the advection term in the momentum equation becomes unnecessary. (b The procedure is meshless in the finite-difference/finite-element sense. (c Tsunami balls care little if they find themselves in the ocean or inundating land. (d Tsunami ball calculations of storm surge can be done on a laptop computer. I demonstrate and calibrate the method by simulating storm surge and inundation around New Orleans, Louisiana caused by Hurricane Katrina in 2005 and by comparing model predictions with field observations. To illustrate the flexibility of the tsunami ball technique, I run two “What If” hurricane scenarios—Katrina over Savannah, Georgia and Katrina over Cape Cod, Massachusetts.

  20. The Long Term Recovery of New Orleans' Population after Hurricane Katrina.

    Fussell, Elizabeth

    2015-09-01

    Hurricane Katrina created a catastrophe in the city of New Orleans when the storm surge caused the levee system to fail on August 29, 2005. The destruction of housing displaced hundreds of thousands of residents for varying lengths of time, often permanently. It also revealed gaps in our knowledge of how population is recovered after a disaster causes widespread destruction of urban infrastructure, housing and workplaces, and how mechanisms driving housing recovery often produce unequal social, spatial and temporal population recovery. In this article, I assemble social, spatial and temporal explanatory frameworks for housing and population recovery and then review research on mobility - both evacuation and migration - after Hurricane Katrina. The review reveals a need for a comprehensive social, spatial and temporal framework for explaining inequality in population recovery and displacement. It also shows how little is known about in-migrants and permanent out-migrants after a disaster.

    2007-06-01

    Hurricane Katrina caused massive destruction and flooding along the Gulf Coast in August 2005. We collected mosquitoes and tested them for arboviral infection in a severely hurricane-damaged community to determine species composition and to assess the risk of a mosquito-borne epidemic disease in that community about 6 wk after the landfall of Hurricane Katrina. Light-trap collections yielded 8,215 mosquitoes representing 19 species, while limited gravid-trap collections were not productive. The most abundant mosquito species was Culex nigripalpus, which constituted 73.6% of all specimens. No arboviruses were detected in any of the mosquitoes collected in this survey, which did not support the assertion that human risk for arboviral infection was increased in the coastal community 6 wk after the hurricane.

  4. Resilience in post-Katrina New Orleans, Louisiana: a preliminary study.

    Glandon, Douglas M; Muller, Jocelyn; Almedom, Astier M

    2008-12-01

    Much scholarly and practitioner attention to the impact of Hurricane Katrina on the city of New Orleans, Louisiana has focused on the failures of government disaster prevention and management at all levels, often overlooking the human strength and resourcefulness observed in individuals and groups among the worst-affected communities. This preliminary study sought to investigate human resilience in the city of New Orleans, State of Louisiana, eighteen months after Hurricane Katrina struck the Mississippi delta region. The Sense of Coherence scale, short form (SOC-13) was administered to a sample of 41 residents of Lower Ninth Ward and adjacent Wards who had been displaced by Hurricane Katrina but were either living in or visiting their home area during March 2007. Study participants were recruited through the local branch of the Association of Community Organizations for Reform Now (ACORN), a nation-wide grassroots organization whose mission is to promote the housing rights of low and moderate-income individuals and families across the USA and in several other countries. Those who had returned to their homes had significantly higher SOC scores compared to those who were still displaced (p<0.001). Among the latter, those who were members of ACORN scored significantly higher than non-members (p<0.005), and their SOC-13 scores were not significantly different from the scores of study participants who had returned home (including both members and non-members of ACORN). The findings of this preliminary study concur with previous reports in the literature on the deleterious impact of displacement on individual and collective resilience to disasters. Relevant insight gleaned from the qualitative data gathered during the course of administering the SOC-13 scale compensate for the limitations of the small sample size as they draw attention to the importance of the study participants' sources of social support. Possible avenues for further research are outlined.

    2018-02-01

    Disaster recovery efforts focus on restoring basic needs to survivors, such as food, water, and shelter. However, long after the immediate recovery phase is over, some individuals will continue to experience unmet needs. Ongoing food insecurity has been identified as a post-disaster problem. There is a paucity of information regarding the factors that might place an individual at risk for continued food insecurity post disaster. Using data from a sample (n=737) of households severely impacted by Hurricane Katrina, we estimated the associations between food insecurity and structural, physical and mental health, and psychosocial factors 5 years after Hurricane Katrina. Logistic regression models were fit and odds ratios (OR) and 95% CI estimated. Nearly one-quarter of respondents (23%) reported food insecurity 5 years post Katrina. Marital/partner status (OR: 0.7, CI: 0.42, 0.99), self-efficacy (OR: 0.56, CI: 0.37, 0.84), sense of community (OR: 0.7, CI: 0.44, 0.98), and social support (OR: 0.59, CI: 0.39, 0.89) lowered the odds of food insecurity and explained most of the effects of mental health distress on food insecurity. Social support, self-efficacy, and being partnered were protective against food insecurity. Recovery efforts should focus on fostering social-support networks and increased self-efficacy to improve food insecurity post disaster. (Disaster Med Public Health Preparedness. 2018;12:47-56).

    Background Empirical observations on how businesses respond after a major catastrophe are rare, especially for a catastrophe as great as Hurricane Katrina, which hit New Orleans, Louisiana on August 29, 2005. We analyzed repeated telephone surveys of New Orleans businesses conducted in December 2005, June 2006, and October 2007 to understand factors that influenced decisions to re-open amid post-disaster uncertainty. Methodology/Principal Findings Businesses in the group of professional, scientific, and technical services reopened the fastest in the near term, but differences in the rate of reopening for businesses stratified by type became indistinguishable in the longer term (around two years later). A reopening rate of 65% was found for all businesses by October 2007. Discriminant analysis showed significant differences in responses reflecting their attitudes about important factors between businesses that reopened and those that did not. Businesses that remained closed at the time of our third survey (two years after Katrina) ranked levee protection as the top concern immediately after Katrina, but damage to their premises and financing became major concerns in subsequent months reflected in the later surveys. For businesses that had opened (at the time of our third survey), infrastructure protection including levee, utility, and communications were the main concerns mentioned in surveys up to the third survey, when the issue of crime became their top concern. Conclusions/Significance These findings underscore the need to have public policy and emergency plans in place prior to the actual disaster, such as infrastructure protection, so that the policy can be applied in a timely manner before business decisions to return or close are made. Our survey results, which include responses from both open and closed businesses, overcome the “survivorship bias” problem and provide empirical observations that should be useful to improve micro-level spatial economic

    Tian, Xian-Liang; Guan, Xian

    2015-01-01

    Objective: The objective of this paper is to examine the impact of Hurricane Katrina on displaced students’ behavioral disorder. Methods: First, we determine displaced students’ likelihood of discipline infraction each year relative to non-evacuees using all K12 student records of the U.S. state of Louisiana during the period of 2000–2008. Second, we investigate the impact of hurricane on evacuee students’ in-school behavior in a difference-in-difference framework. The quasi-experimental nature of the hurricane makes this framework appropriate with the advantage that the problem of endogeneity is of least concern and the causal effect of interest can be reasonably identified. Results: Preliminary analysis demonstrates a sharp increase in displaced students’ relative likelihood of discipline infraction around 2005 when the hurricane occurred. Further, formal difference-in-difference analysis confirms the results. To be specific, post Katrina, displaced students’ relative likelihood of any discipline infraction has increased by 7.3% whereas the increase in the relative likelihood for status offense, offense against person, offense against property and serious crime is 4%, 1.5%, 3.8% and 2.1%, respectively. Conclusion: When disasters occur, as was the case with Hurricane Katrina, in addition to assistance for adult evacuees, governments, in cooperation with schools, should also provide aid and assistance to displaced children to support their mental health and in-school behavior.

    Full Text Available A natural disaster leading to accumulation of environmental contaminants may have substantial effects on the male reproductive system. Our aim was to compare and assess semen parameters in a normospermic population residing in the Southern Louisiana, USA area pre- and post-Hurricane Katrina. We retrospectively evaluated semen analyses data (n = 3452 of 1855 patients who attended the Tulane University Andrology/Fertility Clinic between 1999 and 2013. The study inclusion criteria were men whose semen analyses showed ≥ 1.5 ml volume; ≥15 million ml -1 sperm concentration; ≥39 million total sperm count; ≥40% motility; >30% morphology, with an abstinence interval of 2-7 days. After the inclusion criteria applied to the population, 367 normospermic patients were included in the study. Descriptive statistics and group-based analyses were performed to interpret the differences between the pre-Katrina (Group 1, 1999-2005 and the post-Katrina (Group 2, 2006-2013 populations. There were significant differences in motility, morphology, number of white blood cell, immature germ cell count, pH and presence of sperm agglutination, but surprisingly there were no significant differences in sperm count between the two populations. This long-term comparative analysis further documents that a major natural disaster with its accompanied environmental issues can influence certain semen parameters (e.g., motility and morphology and, by extension, fertility potential of the population of such areas.

    The objective of this paper is to examine the impact of Hurricane Katrina on displaced students' behavioral disorder. First, we determine displaced students' likelihood of discipline infraction each year relative to non-evacuees using all K12 student records of the U.S. state of Louisiana during the period of 2000-2008. Second, we investigate the impact of hurricane on evacuee students' in-school behavior in a difference-in-difference framework. The quasi-experimental nature of the hurricane makes this framework appropriate with the advantage that the problem of endogeneity is of least concern and the causal effect of interest can be reasonably identified. Preliminary analysis demonstrates a sharp increase in displaced students' relative likelihood of discipline infraction around 2005 when the hurricane occurred. Further, formal difference-in-difference analysis confirms the results. To be specific, post Katrina, displaced students' relative likelihood of any discipline infraction has increased by 7.3% whereas the increase in the relative likelihood for status offense, offense against person, offense against property and serious crime is 4%, 1.5%, 3.8% and 2.1%, respectively. When disasters occur, as was the case with Hurricane Katrina, in addition to assistance for adult evacuees, governments, in cooperation with schools, should also provide aid and assistance to displaced children to support their mental health and in-school behavior.

    The long-term environmental impact and potential human health hazards resulting from Hurricanes Katrina and Rita throughout much of the United States Gulf Coast, particularly in the New Orleans, Louisiana, USA area are still being assessed and realized after more than four years. Numerous government agencies and private entities have collected environmental samples from throughout New Orleans and found concentrations of contaminants exceeding human health screening values as established by the United States Environmental Protection Agency (USEPA) for air, soil, and water. To further assess risks of exposure to toxic concentrations of soil contaminants for citizens, particularly children, returning to live in New Orleans following the storms, soils collected from schoolyards prior to Hurricane Katrina and after Hurricane Rita were screened for 26 metals. Concentrations exceeding USEPA Regional Screening Levels (USEPA-RSL), total exposure, non-cancer endpoints, for residential soils for arsenic (As), iron (Fe), lead (Pb), and thallium (Tl) were detected in soil samples collected from schoolyards both prior to Hurricane Katrina and after Hurricane Rita. Approximately 43% (9/21) of schoolyard soils collected prior to Hurricane Katrina contained Pb concentrations greater than 400mgkg(-1), and samples from four schoolyards collected after Hurricane Rita contained detectable Pb concentrations, with two exceeding 1700mgkg(-1). Thallium concentrations exceeded USEPA-RSL in samples collected from five schoolyards after Hurricane Rita. Based upon these findings and the known increased susceptibility of children to the effects of Pb exposure, a more extensive assessment of the soils in schoolyards, public parks and other residential areas of New Orleans for metal contaminants is warranted. 2010 Elsevier Ltd.

    The disaster debris from Hurricane Katrina is one of the largest in terms of volume and economic loss in American history. One of the major components of the demolition debris is wood waste of which a significant proportion is treated with preservatives, including preservatives containing arsenic. As a result of the large scale destruction of treated wood structures such as electrical poles, fences, decks, and homes a considerable amount of treated wood and consequently arsenic will be disposed as disaster debris. In this study an effort was made to estimate the quantity of arsenic disposed through demolition debris generated in the Louisiana and Mississippi area through Hurricane Katrina. Of the 72 million cubic meters of disaster debris generated, roughly 12 million cubic meters were in the form of construction and demolition wood resulting in an estimated 1740 metric tons of arsenic disposed. Management of disaster debris should consider the relatively large quantities of arsenic associated with pressure-treated wood.

  1. Secondary eyewall formation in WRF simulations of Hurricanes Rita and Katrina (2005)

    Abarca, Sergio F.; Corbosiero, Kristen L.

    2011-04-01

    An analysis is presented of two high-resolution hurricane simulations of Katrina and Rita (2005) that exhibited secondary eyewall formation (SEF). The results support the notion of vortex Rossby waves (VRWs) having an important role in SEF and suggest that VRW activity is a defining aspect of the moat. SEF occurs at a radius of ˜65 (80) km in Katrina (Rita), close to the hypothesized stagnation radius of VRWs. VRW activity appears to be the result of eye-eyewall mixing events, themselves a product of the release of barotropic instability. The convection in the radial region that becomes the moat is mainly in the form of VRWs propagating radially outward from the primary eyewall until the negative radial gradient of potential vorticity is no longer conducive for their propagation. These convectively coupled waves, originating and being expelled from the eyewall, are rotation dominated and have the coherency necessary to survive their passage through the strain-dominated region outside the eyewall.

    We investigated the possible relationship between the large- scale heat fluxes and intensity change associated with the landfall of Hurricane Katrina. After reaching the category 5 intensity on August 28th , 2005 over the central Gulf of Mexico, Katrina weekend to category 3 before making landfall (August 29th , 2005) on the Louisiana coast with the maximum sustained winds of over 110 knots. We also examined the vertical motions associated with the intensity change of the hurricane. The data for Convective Available Potential Energy for water vapor (CAPE), sea level pressure and wind speed were obtained from the Atmospheric Soundings, and NOAA National Hurricane Center (NHC), respectively for the period August 24 to September 3, 2005. We also computed vertical motions using CAPE values. The study showed that the large-scale heat fluxes reached maximum (7960W/m2) with the central pressure 905mb. The Convective Available Potential Energy and the vertical motions peaked 3-5 days before landfall. The large atmospheric vertical motions associated with the land falling hurricane Katrina produced severe weather including thunderstorm, tornadoes, storm surge and floods Numerical model (WRF/ARW) with data assimilations have been used for this research to investigate the model's performances on hurricane tracks and intensities associated with the hurricane Katrina, which began to strengthen until reaching Category 5 on 28 August 2005. The model was run on a doubly nested domain centered over the central Gulf of Mexico, with grid spacing of 90 km and 30 km for 6 hr periods, from August 28th to August 30th. The model output was compared with the observations and is capable of simulating the surface features, intensity change and track associated with hurricane Katrina.

  4. Stages of drug market change during disaster: Hurricane Katrina and reformulation of the New Orleans drug market.

    2012-11-01

    In recent years, numerous weather disasters have crippled many cities and towns across the United States of America. Such disasters present a unique opportunity for analyses of the disintegration and reformulation of drug markets. Disasters present new facts which cannot be "explained" by existing theories. Recent and continuing disasters present a radically different picture from that of police crack downs where market disruptions are carried out on a limited basis (both use and sales). Generally, users and sellers move to other locations and business continues as usual. The Katrina Disaster in 2005 offered a larger opportunity to understand the functioning and processes by which drug markets may or may not survive. Utilizing a variety of qualitative data including ethnographic field notes, in-depth interview transcripts, and focus group transcripts, we investigate the operation of the New Orleans drug market before, during, and after Hurricane Katrina. Our data clearly indicate that drug markets go through a series of stages in the wake of disaster in which they disintegrate and then reconstitute themselves. In the case of New Orleans, the post-Katrina drug market was radically different from the pre-Katrina drug market. Ultimately this manuscript presents a paradigm which uses stages as a testable concept to scientifically examine the disintegration and reformulation of drug markets during disaster or crisis situations. It describes the specific processes - referred to as stages - which drug markets must go through in order to function and survive during and after a natural disaster. Copyright © 2012 Elsevier B.V.

    2007-09-01

    This paper analyzes illicit drug markets in New Orleans before and after Hurricane Katrina and access to drug markets following evacuation at many locations and in Houston. Among New Orleans arrestees pre-Katrina, rates of crack and heroin use and market participation was comparable to New York and higher than in other southern cities. Both cities have vigorous outdoor drug markets. Over 100 New Orleans evacuees provide rich accounts describing the illicit markets in New Orleans and elsewhere. The flooding of New Orleans disrupted the city's flourishing drug markets, both during and immediately after the storm. Drug supplies, though limited, were never completely unavailable. Subjects reported that alcohol or drugs were not being used in the Houston Astrodome, and it was a supportive environment. Outside the Astrodome, they were often approached by or could easily locate middlemen and drug sellers. Evacuees could typically access illegal drug markets wherever they went. This paper analyzes the impact of a major disaster upon users of illegal drugs and the illegal drug markets in New Orleans and among the diaspora of New Orleans evacuees following Hurricane Katrina. This analysis includes data from criminal justice sources that specify what the drug markets were like before this disaster occurred. This analysis also includes some comparison cities where no disaster occurred, but which help inform the similarities and differences in drug markets in other cities. The data presented also include an initial analysis of ethnographic interview data from over 100 New Orleans Evacuees recruited in New Orleans and Houston.

    Substance abuse treatment following a natural disaster is often met with challenges. If treatment is available, facilities may be unequipped to service an influx of patients or provide specialized care for unique populations. This paper seeks to evaluate trends in substance abuse treatment over time and assess changes pre- and post-Hurricane Katrina. Substance abuse treatment admission data (N = 42,678) from New Orleans, Louisiana, for years 2000 through 2012 were obtained from the Treatment Episode Data Set. Admissions were examined to evaluate demographic, socioeconomic, psychiatric, and criminality trends in substance abuse treatment and assess changes following Hurricane Katrina. Treatment admissions have decreased from 2000 to 2012. About one in five admissions had a psychiatric illness in addition to a substance abuse problem. A staggering 76% of admissions with a psychiatric illness were referred by the criminal justice system post-Katrina as compared to pre-Katrina. Rates of alcohol and marijuana admissions have remained stable from 2000 to 2012. Cocaine/crack admissions have declined and admissions who abused heroin have increased over time. Treatment admissions stabilized following Hurricane Katrina; however, since 2009, they have begun to decline. Targeted exploration of factors affecting admission to treatment in New Orleans with populations such as the homeless, those with a psychiatric illness in addition to a substance abuse problem, and those referred by the criminal justice system is essential. The results of this study assist in identifying variations in substance abuse treatment characteristics for those admitted to treatment in New Orleans.

    Recovery from disaster and displacement involves multiple challenges including accompanying survivors, documenting effects, and rethreading community. This paper demonstrates how African-American and Latina community health promoters and white university-based researchers engaged visual methodologies and participatory action research (photoPAR) as resources in cross-community praxis in the wake of Hurricane Katrina and the flooding of New Orleans. Visual techniques, including but not limited to photonarratives, facilitated the health promoters': (1) care for themselves and each other as survivors of and responders to the post-disaster context; (2) critical interrogation of New Orleans' entrenched pre- and post-Katrina structural racism as contributing to the racialised effects of and responses to Katrina; and (3) meaning-making and performances of women's community-based, cross-community health promotion within this post-disaster context. This feminist antiracist participatory action research project demonstrates how visual methodologies contributed to the co-researchers' cross-community self- and other caring, critical bifocality, and collaborative construction of a contextually and culturally responsive model for women's community-based health promotion post 'unnatural disaster'. Selected limitations as well as the potential for future cross-community antiracist feminist photoPAR in post-disaster contexts are discussed.

  15. Rebuilding the past: health care reform in post-Katrina Louisiana.

    Science.gov (United States)

    Clark, Mary A

    2010-10-01

    After Hurricane Katrina, there was good reason to believe that a gaping window of opportunity had opened for Louisiana to revamp its safety-net health care system. But two years of discussions among stakeholders within Louisiana and extensive negotiations with federal officials resulted in no such change. This article argues that any explanation for this outcome needs to incorporate both structure and process. In terms of structure, the rules of the Medicaid disproportionate-share hospital (DSH) program give states substantial independent authority to decide which hospitals to fund. Federal authorities could not force Louisiana, which had historically turned its DSH money over to the state hospital system, to redirect it toward an insurance expansion. In the process of negotiation after Katrina, those who defended the institutions wedded to the prestorm status quo conducted a better strategy than their challengers. They narrowed the purview of the Louisiana Health Care Redesign Collaborative, set up to propose changes in the safety net to the federal government, such that the question of whether to rebuild Charity Hospital in New Orleans was off the table. Meanwhile, on a separate track, the state and the Department of Veterans Affairs successfully pursued a plan to jointly build replacement hospitals.

    This research explores the relationship between political campaign contributions, lobbying and post-Hurricane Katrina cleanup and reconstruction contracts. Specifically, a case-control study design is used to determine whether campaign contributions to national candidates in the 2000-04 election cycles and/or the employment of lobbyists and lobbying firms increased a company's probability of receiving a post-hurricane contract. Results indicate that both a campaign contribution dichotomous variable and the dollar amount of contributions are significantly related to whether a company received a contract, but that lobbying activity was not. These findings are discussed in the context of previous research on the politics of natural disasters, government contracting and governmental and corporate deviance.

    This paper reports on the effects of Hurricanes Katrina and Rita on drug and alcohol treatment in Texas in 2005-2006. Findings are based on a secondary analysis of administrative data on 567 hurricane-related admissions and on interview data from a sample of 20 staff in 11 treatment programs. Katrina evacuees differed from Rita clients in terms of demographics and primary problem substances and treatment needs, while the experiences of program staff and needed changes to improve disaster readiness were more similar. Additional systematic research is needed to document the intermediate and long-term impacts of the storms in these and other affected areas.

    When Hurricane Katrina slammed into New Orleans on August 29, 2005, the failure of the levees resulted in the largest single human-made disaster in the United States. In addition to the physical devastation of the city, the landscape of public schools in New Orleans was permanently altered, as was the national dialogue about school reform in the…

    Hurricanes can greatly modify the sedimentary record, but our coastal scientific community has rather limited capability to predict hurricane-induced sediment deposition. A three-dimensional sediment transport model was developed in the Regional Ocean Modeling System (ROMS) to study seabed erosion and deposition on the Louisiana shelf in response to Hurricanes Katrina and Rita in the year 2005. Sensitivity tests were performed on both erosional and depositional processes for a wide range of erosional rates and settling velocities, and uncertainty analysis was done on critical shear stresses using the polynomial chaos approximation method. A total of 22 model runs were performed in sensitivity and uncertainty tests. Estimated maximum erosional depths were sensitive to the inputs, but horizontal erosional patterns seemed to be controlled mainly by hurricane tracks, wave-current combined shear stresses, seabed grain sizes, and shelf bathymetry. During the passage of two hurricanes, local resuspension and deposition dominated the sediment transport mechanisms. Hurricane Katrina followed a shelf-perpendicular track before making landfall and its energy dissipated rapidly within about 48 h along the eastern Louisiana coast. In contrast, Hurricane Rita followed a more shelf-oblique track and disturbed the seabed extensively during its 84-h passage from the Alabama-Mississippi border to the Louisiana-Texas border. Conditions to either side of Hurricane Rita's storm track differed substantially, with the region to the east having stronger winds, taller waves and thus deeper erosions. This study indicated that major hurricanes can disturb the shelf at centimeter to meter levels. Each of these two hurricanes suspended seabed sediment mass that far exceeded the annual sediment inputs from the Mississippi and Atchafalaya Rivers, but the net transport from shelves to estuaries is yet to be determined. Future studies should focus on the modeling of sediment exchange between

    We examined the effects of Hurricane Katrina on disability-related measures of health among adults from New Orleans, U.S.A., in the year after the hurricane, with a focus on differences by age, race, and sex. Our analysis used data from the American Community Survey to compare disability rates between the pre-Katrina population of New Orleans with the same population in the year after Katrina (individuals were interviewed for the study even if they relocated away from the city). The comparability between the pre- and post-Katrina samples was enhanced by using propensity weights. We found a significant decline in health for the adult population from New Orleans in the year after the hurricane, with the disability rate rising from 20.6% to 24.6%. This increase in disability reflected a large rise in mental impairments and, to a lesser extent, in physical impairments. These increases were, in turn, concentrated among young and middle-aged black females. Stress-related factors likely explain why young and middle-aged black women experienced worse health outcomes, including living in dwellings and communities that suffered the most damage from the hurricane, household breakup, adverse outcomes for their children, and higher susceptibility.

    Full Text Available This article explores the state of emergency following Hurrican Katrina or ‘the Katrina Event’ with reference to the role of media first responders. Throughout the ensuing disaster the performance of the media (including celebrity advocates like Oprah Winfrey, Geraldo Rivera and Kanye West worked as a mechanism for technical remastery in the face of systemic breakdown. This re-mediation of panic and of the state of emergency shifted attention from the local (that is, from the acts of witness by Katrina’s victims to national reactions (as figured by advocates of the cause of the neglected poor of New Orleans. In this way even as voice was given to the failure of the nation to rise to the needs of its most vulnerable citizens, the figure of the nation as carer was re-instantiated in the televised outrage and frustration of talk show hosts, news anchors, and charity fund-raising celebrities.

    Full Text Available In this paper, we draw on multi-level census data, in-depth interviews, ethnographic and Geographical Information Systems (GIS methods to examine the effects of median household income, ethnoracial diversity, and flood damage on rates of post-Katrina repopulation in New Orleans. Our main finding is that New Orleans neighborhoods have been experiencing modest increases in ethnoracial diversity as well as a retrenchment of socio-spatial inequalities, as measured by low diversity scores, low median household income levels, and high poverty rates. In addition to documenting the objective indicators of “recovery”, we draw attention to the socially constructed nature of resilience. Based on interviews and ethnographic field observations, we investigate how resident constructions of resilience shape their views of the post-Katrina recovery process, provide a compelling and reassuring story of community revitalization, and convey a sense of collective power and control despite continued vulnerability to hazards and disasters.

    Anthropogenic re-distribution of lead (Pb) principally through its use in gasoline additives and lead-based paints have transformed the urban exposome. This unique study tracks urban-scale soil Pb (SPb) and blood Pb (BPb) responses of children living in public and private communities in New Orleans before and ten years after Hurricane Katrina (29 August 2005). To compare and evaluate associations of pre- and ten years post-Katrina SPb and children's BPb on public and private residential census tracts in the core and outer areas of New Orleans, and to examine correlations between SPb and nine other soil metals. The Louisiana Healthy Housing and Childhood Lead Poisoning Prevention Program BPb (µg/dL) data from pre- (2000-2005) and post-Katrina (2010-2015) for ≤6-year-old children. Data from public and adjacent private residential census tracts within core and outer areas are stratified from a database that includes 916 and 922 SPb and 13,379 and 4830 BPb results, respectively, from pre- and post-Katrina New Orleans. Statistical analyses utilize Multi-Response Permutation Procedure and Spearman's Rho Correlation. Pre- to Post-Katrina median SPb decreases in public and private core census tracts were from 285 to 55mg/kg and 710-291mg/kg, respectively. In public and private outer census tracts the median SPb decreased from 109 to 56mg/kg and 88-55mg/kg. Children's BPb percent ≥5µg/dL on public and private core areas pre-Katrina was 63.2% and 67.5%, and declined post-Katrina to 7.6% and 20.2%, respectively. BPb decreases also occurred in outer areas. Soil Pb is strongly correlated with other metals. Post-Katrina re-building of public housing plus landscaping amends the exposome and reduces children's BPb. Most importantly, Hurricane Katrina revealed that decreasing the toxicants in the soil exposome is an effective intervention for decreasing children's BPb. Copyright © 2017 Elsevier Inc.

    Hurricanes have the potential to alter the structures of coastal ecosystems and generate pathogen-laden floodwaters thatthreaten public health. To examine the impact of hurricanes on urban systems, we compared microbial community structures in samples collected after Hurricane Katrina and before and after Hurricane Rita. We extracted environmental DNA and sequenced small-subunit rRNA (SSU rRNA) gene clone libraries to survey microbial communities in floodwater, water, and sediment samples collected from Lake Charles, Lake Pontchartrain, the 17th Street and Industrial Canals in New Orleans, and raw sewage. Correspondence analysis showed that microbial communities associated with sediments formed one cluster while communities associated with lake and Industrial Canal water formed a second. Communities associated with water from the 17th Street Canal and floodwaters collected in New Orleans showed similarity to communities in raw sewage and contained a number of sequences associated with possible pathogenic microbes. This suggests that a distinct microbial community developed in floodwaters following Hurricane Katrina and that microbial community structures as a whole might be sensitive indicators of ecosystem health and serve as "sentinels" of water quality in the environment.

    This study evaluated how individuals living on the Gulf Coast perceived hurricane risk after Hurricanes Katrina and Rita. It was hypothesized that hurricane outlook and optimistic bias for hurricane risk would be associated positively with distance from the Katrina-Rita landfall (more optimism at greater distance), controlling for historically based hurricane risk and county population density, demographics, individual hurricane experience, and dispositional optimism. Data were collected in January 2006 through a mail survey sent to 1,375 households in 41 counties on the coast (n = 824, 60% response). The analysis used hierarchal regression to test hypotheses. Hurricane history and population density had no effect on outlook; individuals who were male, older, and with higher household incomes were associated with lower risk perception; individual hurricane experience and personal impacts from Katrina and Rita predicted greater risk perception; greater dispositional optimism predicted more optimistic outlook; distance had a small effect but predicted less optimistic outlook at greater distance (model R(2) = 0.21). The model for optimistic bias had fewer effects: age and community tenure were significant; dispositional optimism had a positive effect on optimistic bias; distance variables were not significant (model R(2) = 0.05). The study shows that an existing measure of hurricane outlook has utility, hurricane outlook appears to be a unique concept from hurricane optimistic bias, and proximity has at most small effects. Future extension of this research will include improved conceptualization and measurement of hurricane risk perception and will bring to focus several concepts involving risk communication. © 2011 Society for Risk Analysis.

    2011-03-01

    Full Text Available Hurricane Katrina displaced nearly one million citizens from the New Orleans metro region in 2005. Five years after the catastrophe, in August of 2010, more than 150,000 citizens remained scattered across the United States. Katrina was the largest Diaspora in the nation’s history. The number of homes damaged or destroyed by Katrina’s devastation numbered more than 125,000. An award-winning case study is presented of a unique partnership forged between academia, a local social service agency, professional architectural and engineering firms, and a national humanitarian aid organization whose mission is to provide affordable housing for homeless persons in transition. This collaboration resulted in a sustainable design/build project that originated in a research-based university design studio. The facility is a 38-bed family shelter for homeless mothers and their children seeking to rebuild their lives in post-Katrina New Orleans. The site for this 4,400 facility did not flood when the city’s federally built levee system failed in 2005. This case study is presented from its inception, to programming and design, construction, occupancy, and the postoccupancy assessment of the completed building. This facility is the first LEED certified (Silver building in New Orleans. Project limitations, lessons learned, and recommendations for future initiatives of this type are discussed, particularly in the context of any inner urban community coping with the aftermath of an urban disaster.

  6. Katrina and Rita were lit up with lightning

    Shao, X.-M.; Harlin, J.; Stock, M.; Stanley, M.; Regan, A.; Wiens, K.; Hamlin, T.; Pongratz, M.; Suszcynsky, D.; Light, T.

    Hurricanes generally produce very little lightning activity compared to other noncyclonic storms, and lightning is especially sparse in the eye wall and inner regions within tens of kilometers surrounding the eye [Molinari et al., 1994, 1999]. (The eye wall is the wall of clouds that encircles the eye of the hurricane.) Lightning can sometimes be detected in the outer, spiral rainbands, but the lightning occurrence rate varies significantly from hurricane to hurricane as well as within an individual hurricane's lifetime.Hurricanes Katrina and Rita hit the U.S. Gulf coasts of Louisiana, Mississippi, and Texas, and their distinctions were not just limited to their tremendous intensity and damage caused. They also differed from typical hurricanes in their lightning production rate.

On August 29, 2005, they were impacted heavily by the wind, waves, and storm surges of Hurricane Katrina. The purpose of this study is to determine the growth responses of Quercus geminata, a dominant tree species on Cat Island, MS, in relation to the impact of Hurricane Katrina. Remotely sensed data was utilized in conjunction with ground data to assess growth response post Hurricane Katrina. The main objectives of this study were: 1) determine growth response of Q. geminata through tree ring analysis; 2) understand how Q. geminata adapted to intense weather and climatic phenomena on Cat Island. The hypotheses tested were: 1) growth rates of Q. geminata on Cat Island were decreased by the impact of Hurricane Katrina 2) trees at higher elevations survived or recovered while trees at lower elevations did not recover or died. Decadal scale stability is required for forest stand development on siliciclastic barrier islands. Thus, monitoring the distribution of forest climax community species is key to understanding siliciclastic, subsiding, barrier island geomorphic processes and their relationships to successional patterns and growth rates. Preliminary results indicate that Q. geminata produces a faint growth ring, survive for at least two to three hundred years and is well-adapted to frequent salt water flooding.

    Rain and flooding from Hurricane Katrina resulted in widespread growth of mold and bacteria and production of allergens in New Orleans, Louisiana, which may have led to increased exposures and morbidity in children with asthma. The goal of the Head-off Environmental Asthma in Louisiana (HEAL) study was to characterize post-Katrina exposures to mold and allergens in children with asthma. The homes of 182 children with asthma in New Orleans and surrounding parishes were evaluated by visual inspection, temperature and moisture measurements, and air and dust sampling. Air was collected using vacuum-pump spore traps and analyzed for > 30 mold taxa using bright field microscopy. Dust was collected from the children's beds and bedroom floors and analyzed for mouse (Mus m 1), dust mite (Der p 1), cockroach (Bla g 1), and mold (Alternaria mix) allergens using ELISA. More than half (62%) of the children were living in homes that had been damaged by rain, flooding, or both. Geometric mean indoor and outdoor airborne mold levels were 501 and 3,958 spores/m3, respectively. Alternaria antigen was detected in dust from 98% of homes, with 58% having concentrations > 10 µg/g. Mus m 1, Der p 1, and Bla g 1 were detected in 60%, 35%, and 20% of homes, respectively, at low mean concentrations. Except for Alternaria antigen in dust, concentrations of airborne mold (ratio of indoor to outdoor mold) and dust allergens in the homes of HEAL children were lower than measurements found in other studies, possibly because of extensive post-Katrina mold remediation and renovations, or because children moved into cleaner homes upon returning to New Orleans.

    The massive destruction caused by Hurricanes Katrina and Rita in 2005 provided an opportunity for many volunteers to be involved with disaster relief work. Exposure to devastation and personal trauma can have long-lasting and sometimes detrimental effects on people providing help. This qualitative study explored the experience of volunteer relief workers who provided disaster relief services after the hurricanes. Three major themes emerged: emotional reactions that included feelings of shock, fatigue, anger and grief as well as sleep disturbances; frustration with leadership; and life-changing personal transformation. Stress reactions were noted but appeared to be mitigated by feelings of compassion for the victims and personal satisfaction in being able to provide assistance. Suggestions are provided for further research.

La utilidad de este tipo de medida como otro método para evaluar la biodiversidad de los ecosistemas marinos bentónicos de fondos blandos del Golfo de Batabanó (Cuba se comprobó mediante el uso de los índices de distinción taxonómica promedio (Delta+ y la variación en la distinción taxonómica (Lambda+ de las comunidades de moluscos. Para este propósito, se utilizaron los inventarios de especies de moluscos bentónicos de fondos blandos obtenidos en el periodo 1981-1985 y en los años 2004 y 2007. Ambos listados de especies fueron analizados y comparados a escala espacial y temporal. La composición taxonómica entre el periodo y años estudiados se conformó de 3 clases, 20 órdenes, 60 familias, 137 géneros y 182 especies, observándose, excepto en el nivel de clase, una disminución no significativa de esta composición en 2004 y 2007. A escala espacial se detectó una disminución significativa en la riqueza taxonómica en el 2004. No se detectaron diferencias significativas en Delta+ y Lambda+ a escala temporal, pero si a escala espacial, hecho que se puede atribuir al efecto combinado del incremento de las actividades antropogénicas en la región con los efectos inducidos por los huracanes. Estos resultados sugieren que el par de índices Delta+ y Lambda+ son buenos descriptores de la biodiversidad de las comunidades de moluscos bentónicos de fondos blandos del Golfo de Batabanó.

    The effects of Hurricanes Katrina and Rita and the subsequent unwatering of New Orleans, Louisiana, on the sediment chemistry of Lake Pontchartrain were evaluated by chemical analysis of samples of street mud and suspended and bottom sediments. The highest concentrations of urban-related elements and compounds (e.g., Pb, Zn, polycyclic aromatic hydrocarbons, and chlordane) in bottom sediments exceeded median concentrations in U.S. urban lakes and sediment-quality guidelines. The extent of the elevated concentrations was limited, however, to within a few hundred meters of the mouth of the 17th Street Canal, similar to results of historical assessments. Chemical and radionuclide analysis of pre- and post-Hurricane Rita samples indicates that remobilization of near-shore sediment by lake currents and storms is an ongoing process. The effects of Hurricanes Katrina and Rita on the sediment chemistry of Lake Pontchartrain are limited spatially and are most likely transitory. ?? 2006 American Chemical Society.

    Engaging non-majors to become interested in the geosciences college courses they take for a science requirement represents a challenge. These courses are most likely the only exposure they will ever have to a formal earth science curriculum. Experience shows a general lack of motivation and the need to find effective teaching methods to raise their interest. In the beginning of the fall 2005 semester, I participated in a research project to measure water vapor contents on the ground of the eye of hurricane Katrina in Slidell, Louisiana. Sharing this experience with my physical and environmental geology students made a significant difference (25 percentage final grade improvement) on their interest and course performance over previous semesters. Class presentations with data collected in Katrina contributed to build a general trust in the instructor and in the way, students viewed the role of geosciences in the mitigation of natural hazardous processes. The use of travel blogs and internet enhanced courses allows teaching real time from almost anywhere as it was recently done from the east pacific (360 miles NW from Guam). An interactive portfolio of the faculty field experiences presented at the beginning of the semester has the potential to build student interest and their trust on the faculty experience and passion for the subject.

    Disparities in neighborhood food access are well documented, but little research exists on how shocks influence such disparities. We examined neighborhood food access in New Orleans at 3 time points: before Hurricane Katrina (2004–2005), in 2007, and in 2009. We combined existing directories with on-the-ground verification and geographic information system mapping to assess supermarket counts in the entire city. Existing disparities for African American neighborhoods worsened after the storm. Although improvements have been made, by 2009 disparities were no better than prestorm levels. PMID:21233432

  8. Predictors of business return in New Orleans after Hurricane Katrina.

    Full Text Available We analyzed the business reopening process in New Orleans after Hurricane Katrina, which hit the region on August 29, 2005, to better understand what the major predictors were and how their impacts changed through time. A telephone survey of businesses in New Orleans was conducted in October 2007, 26 months after Hurricane Katrina. The data were analyzed using a modified spatial probit regression model to evaluate the importance of each predictor variable through time. The results suggest that the two most important reopening predictors throughout all time periods were the flood depth at the business location and business size as represented by its wages in a logarithmic form. Flood depth was a significant negative predictor and had the largest marginal effects on the reopening probabilities. Smaller businesses had lower reopening probabilities than larger ones. However, the nonlinear response of business size to the reopening probability suggests that recovery aid would be most effective for smaller businesses than for larger ones. The spatial spillovers effect was a significant positive predictor but only for the first nine months. The findings show clearly that flood protection is the overarching issue for New Orleans. A flood protection plan that reduces the vulnerability and length of flooding would be the first and foremost step to mitigate the negative effects from climate-related hazards and enable speedy recovery. The findings cast doubt on the current coastal protection efforts and add to the current debate of whether coastal Louisiana will be sustainable or too costly to protect from further land loss and flooding given the threat of sea-level rise. Finally, a plan to help small businesses to return would also be an effective strategy for recovery, and the temporal window of opportunity that generates the greatest impacts would be the first 6∼9 months after the disaster.

    2011-01-01

    Hurricanes Katrina and Rita impacted a large portion of the medical community in Louisiana. We attempt to determine their impact on the anesthesiology workforce in Louisiana. In May 2006, a survey was mailed to 368 Louisiana anesthesiologists, collecting demographic data, retirement plans, impact of Hurricanes Katrina and Rita, position vacancies, practice conditions, and the general state of healthcare in their area. All 3 anesthesiology residency programs in the state were contacted regarding their recent graduates. The 2010 RAND survey of the anesthesiology workforce was reviewed with respect to findings relevant to the state and region. One hundred seventy surveys were returned, yielding a 46.2% response rate. Among the respondents, 13.9% intended to retire within 5 years and another 24% in 5 to 10 years. Since 2005, 63.9% had seen an increase in their daily caseload, 46.9% saw an increase in work hours, and 36.8% stated that their practices were trying to hire new anesthesiologists and were having difficulty filling these positions. Since 2005, the number of anesthesiology residents in Louisiana had declined by almost 50%, and the number of graduates remaining to practice in Louisiana had decreased by 43% from 7 to 4 annually. Our 2006 survey provided qualitative evidence for a shortage of anesthesiologists in the state of Louisiana after the natural disasters in 2005 that was likely to worsen as residency output plummeted, fewer residents stayed in the state, and projected retirement increased. The regional data from the RAND survey a year later confirmed the impressions from our survey, with an estimate of an anesthesiologist shortage as high as 39% of the workforce. State membership surveys may serve as accurate barometers in the wake of major environmental upheavals affecting regional anesthesiology workforce conditions.

    Although blacks are more likely than whites to experience posttraumatic stress disorder (PTSD) after a natural disaster, the reasons for this disparity are unclear. This study explores whether race is associated with PTSD after adjusting for differences in preexisting vulnerabilities, exposure to stressors, and loss of social support due to Hurricane Katrina using a representative sample of 279 black and white adult current and past smokers who were present when Hurricane Katrina struck, and identified it as the most traumatic event in their lifetime. Multiple logistic regression models evaluated whether differential vulnerability (pre-hurricane physical and mental health functioning, and education level), differential exposure to hurricane-related stressors, and loss of social support deterioration reduced the association of race with PTSD. Blacks were more likely than whites to screen positive for PTSD (49 vs. 39 %, respectively, p = 0.030). Although blacks reported greater pre-hurricane vulnerability (worse mental health functioning and lower educational attainment) and hurricane-related stressor exposure and had less social support after the hurricane, only pre-hurricane mental health functioning attenuated the association of race with screening positive for PTSD. Thus, racial differences in pre-hurricane functioning, particularly poorer mental health, may partially explain racial disparities in PTSD after natural disasters, such as Hurricane Katrina. Future studies should examine these associations prospectively using representative cohorts of black and whites and include measures of residential segregation and discrimination, which may further our understanding of racial disparities in PTSD after a natural disaster.

    The severe consequences of Hurricane Katrina on mental health have sparked tremendous interest in improving the quality of mental health care for disaster victims. In this special issue, we seek to illustrate the breadth of work emerging in this area. The five empirical examples each reflect innovation, either in the nature of the services being provided or in the evaluation approach. Most importantly, they portray the variability of post-Katrina mental health programs, which ranged from national to state to local in scope and from educational to clinical in intensity. As a set, these papers address the fundamental question of whether it is useful and feasible to provide different intensities of mental health care to different populations according to presumed need. The issue concludes with recommendations for future disaster mental health service delivery and evaluation.

    To determine the impact of Hurricane Katrina on the psychosocial health of people with disabilities and on the ability of people with disabilities in the affected area to live independently. Transcribed conversations were analyzed for 56 survivors of Hurricane Katrina on the American Gulf Coast, all of whom were persons with disabilities or persons working with them. Semi-structured interviews were conducted either individually or in focus groups with participants. Qualitative analysis was undertaken using hermeneutic techniques. Six major themes emerged: faith, incredulousness, blaming others or oneself, family adaptation and resiliency, and work and professional responsibility. The resiliency of persons with disabilities to adapt to disasters can be better understood through factors such as these, providing an effective barometer of social capital that can help societies prepare for future disasters among those most vulnerable.

    2009-01-01

    The damages caused by the storm surges from Hurricane Katrina and Hurricane Rita were significant and occurred over broad areas. Storm-surge maps are among the most useful geospatial datasets for hurricane recovery, impact assessments, and mitigation planning for future storms. Surveyed high-water marks were used to generate a maximum storm-surge surface for Hurricane Katrina extending from eastern Louisiana to Mobile Bay, Alabama. The interpolated surface was intersected with high-resolution lidar elevation data covering the study area to produce a highly detailed digital storm-surge inundation map. The storm-surge dataset and related data are available for display and query in a Web-based viewer application. A unique water-level dataset from a network of portable pressure sensors deployed in the days just prior to Hurricane Rita's landfall captured the hurricane's storm surge. The recorded sensor data provided water-level measurements with a very high temporal resolution at surveyed point locations. The resulting dataset was used to generate a time series of storm-surge surfaces that documents the surge dynamics in a new, spatially explicit way. The temporal information contained in the multiple storm-surge surfaces can be visualized in a number of ways to portray how the surge interacted with and was affected by land surface features. Spatially explicit storm-surge products can be useful for a variety of hurricane impact assessments, especially studies of wetland and land changes where knowledge of the extent and magnitude of storm-surge flooding is critical.

  20. Mapping Pollution Plumes in Areas Impacted by Hurricane Katrina With Imaging Spectroscopy

    New Orleans endured flooding on a massive scale subsequent to Hurricane Katrina in August of 2005. Contaminant plumes were noticeable in satellite images of the city in the days following flooding. Many of these plumes were caused by oil, gasoline, and diesel that leaked from inundated vehicles, gas stations, and refineries. News reports also suggested that the flood waters were contaminated with sewage from breached pipes. Effluent plumes such as these pose a potential health hazard to humans and wildlife in the aftermath of hurricanes and potentially from other catastrophic events (e.g., earthquakes, shipping accidents, chemical spills, and terrorist attacks). While the extent of effluent plumes can be gauged with synthetic aperture radar and broad- band visible-infrared images (Rykhus, 2005) (e.g., Radarsat and Landsat ETM+) the composition of the plumes could not be determined. These instruments lack the spectral resolution necessary to do chemical identification. Imaging spectroscopy may help solve this problem. Over 60 flight lines of NASA Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) data were collected over New Orleans, the Mississippi Delta, and the Gulf Coast from one to two weeks after Katrina while the contaminated water was being pumped out of flooded areas. These data provide a unique opportunity to test if imaging spectrometer data can be used to identify the chemistry of these flood-related plumes. Many chemicals have unique spectral signatures in the ultraviolet to near-infrared range (0.2 - 2.5 microns) that can be used as fingerprints for their identification. We are particularly interested in detecting thin films of oil, gasoline, diesel, and raw sewage suspended on or in water. If these materials can be successfully differentiated in the lab then we will use spectral-shape matching algorithms to look for their spectral signatures in the AVIRIS data collected over New Orleans and other areas impacted by Katrina.

    Introduction Hurricane Katrina made landfall on the eastern coastline of Louisiana on August 29, 2005; Hurricane Rita made landfall on the western coastline of Louisiana on September 24, 2005. Comparison of Landsat Thematic Mapper (TM) satellite imagery acquired before and after the landfalls of Katrina and Rita and classified to identify land and water demonstrated that water area increased by 217 mi2 (562 km2) in coastal Louisiana as a result of the storms. Approximately 82 mi2 (212 km2) of new water areas were in areas primarily impacted by Hurricane Katrina (Mississippi River Delta basin, Breton Sound basin, Pontchartrain basin, and Pearl River basin), whereas 99 mi2 (256 km2) were in areas primarily impacted by Hurricane Rita (Calcasieu/Sabine basin, Mermentau basin, Teche/Vermilion basin, Atchafalaya basin, and Terrebonne basin). Barataria basin contained new water areas caused by both hurricanes, resulting in some 18 mi2 (46.6 km2) of new water areas. The fresh marsh and intermediate marsh communities' land areas decreased by 122 mi2 (316 km2) and 90 mi2 (233.1 km2), respectively, and the brackish marsh and saline marsh communities' land areas decreased by 33 mi2 (85.5 km2) and 28 mi2 (72.5 km2), respectively. These new water areas represent land losses caused by direct removal of wetlands. They also indicate transitory changes in water area caused by remnant flooding, removal of aquatic vegetation, scouring of marsh vegetation, and water-level variation attributed to normal tidal and meteorological variation between satellite images. Permanent losses cannot be estimated until several growing seasons have passed and the transitory impacts of the hurricanes are minimized. The purpose of this study was to provide preliminary information on water area changes in coastal Louisiana acquired shortly after the landfalls of both hurricanes (detectable with Landsat TM imagery) and to serve as a regional baseline for monitoring posthurricane wetland recovery.

  5. Cloud Spirals and Outflow in Tropical Storm Katrina

    2005-01-01

    On Tuesday, August 30, 2005, NASA's Multi-angle Imaging SpectroRadiometer retrieved cloud-top heights and cloud-tracked wind velocities for Tropical Storm Katrina, as the center of the storm was situated over the Tennessee valley. At this time Katrina was weakening and no longer classified as a hurricane, and would soon become an extratropical depression. Measurements such as these can help atmospheric scientists compare results of computer-generated hurricane simulations with observed conditions, ultimately allowing them to better represent and understand physical processes occurring in hurricanes. Because air currents are influenced by the Coriolis force (caused by the rotation of the Earth), Northern Hemisphere hurricanes are characterized by an inward counterclockwise (cyclonic) rotation towards the center. It is less widely known that, at high altitudes, outward-spreading bands of cloud rotate in a clockwise (anticyclonic) direction. The image on the left shows the retrieved cloud-tracked winds as red arrows superimposed across the natural color view from MISR's nadir (vertical-viewing) camera. Both the counter-clockwise motion for the lower-level storm clouds and the clockwise motion for the upper clouds are apparent in these images. The speeds for the clockwise upper level winds have typical values between 40 and 45 m/s (144-162 km/hr). The low level counterclockwise winds have typical values between 7 and 24 m/s (25-86 km/hr), weakening with distance from the storm center. The image on the right displays the cloud-top height retrievals. Areas where cloud heights could not be retrieved are shown in dark gray. Both the wind velocity vectors and the cloud-top height field were produced by automated computer recognition of displacements in spatial features within successive MISR images acquired at different view angles and at slightly different times. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously, viewing the entire globe

    The extensive flooding in the aftermath of Hurricanes Katrina and Rita created conditions ideal for indoor mold growth, raising concerns about the possible adverse health effects associated with indoor mold exposure. Studies evaluating the levels of indoor and outdoor molds in the months following the hurricanes found high levels of mold growth. Homes with greater flood damage, especially those with >3 feet of indoor flooding, demonstrated higher levels of mold growth compared with homes with little or no flooding. Water intrusion due to roof damage was also associated with mold growth. However, no increase in the occurrence of adverse health outcomes has been observed in published reports to date. This article considers reasons why studies of mold exposure after the hurricane do not show a greater health impact.

    2007-08-01

    As a result of Hurricane Katrina on August 29, 2005, ED nurses were faced with chaos during and after the storm. The purpose of this pilot study was to determine if emergency nurses have experienced signs and symptoms of post-traumatic stress disorder (PTSD) as a result of working in an emergency department of the New Orleans metropolitan area during and immediately after Hurricane Katrina. The research identifies if the nurses perceived satisfaction with measures administrators took to provide Critical Incident Stress Management (CISM). To combat burnout, absenteeism, emotional difficulties, and health problems in nurses, administration must offer adequate crisis management for those affected by a traumatic event in the workplace. Data were captured through a cross-sectional research design using self-reporting questionnaires. A questionnaire captured demographic information as well as information regarding satisfaction with CISM offered by management. The Post Traumatic Checklist (PCL) was utilized to assess PTSD symptoms in the nurse. An emergency department located approximately 40 miles north of downtown New Orleans, Louisiana, served as the setting for this study. The sample included 21 registered nurses who worked in the emergency department. Twenty percent of the nurses has symptoms of PTSD. In addition, 100% of the nurses reported that administrators did not offer CISM. To combat consequences of long-term effects of PTSD, hospital administrators must offer adequate treatment to employees. Further research is needed to expand the sample and gain a wider perspective on PTSD symptoms in nurses who worked during the Hurricane.

    In an effort to extend the length of GPS baselines further offshore, the Hydrographic Science Research Center at the University of Southern Mississippi deployed a buoy which had a survey grade GPS receiver, an ADPC and a motion sensor unit in the Mississippi Bight in late 2004. The GPS data were initially processed using the Post Processed Kinematic technique with data from a nearby GPS base station on Horn Island. This processing technique discontinued when the storm (Hurricane Katrina) destroyed the base station in late August of 2005. However, since then a stand-alone positioning technique termed Precise Point Positioning (PPP) matured and allowed for the reprocessing of the buoy GPS data throughout Katrina. The processed GPS data were corrected for buoy angular motions using Tait Bryan transformation model. Tidal datums (Epoch 1983-2001) were transferred from the National Oceanic and Atmospheric Administration (NOAA) National Water Level at Waveland, Mississippi (Station ID 8747766) to the buoy using the Modified Range Ratio method. The maximum water level during the storm was found to be about 3.578m, relative to the transferred Mean Sea Level datum. The storm surge built over more than 24 hours, but fell back to normal levels in less than 3 hours. The maximum speed of the current with respect to the seafloor was recorded to be about 4knots towards the southeast as the storm surge moved back offshore.

Hoy surge una nueva posibilidad de desarrollo sostenible con la plantación de mango “Ataúlfo”, una variedad de origen local que ha sido desarrollada hasta llegar a ser uno de los cultivos más importantes de la región desde el punto de vista de productividad y rentabilidad. El fruto de esta variedad presenta características morfológicas y organolépticas muy deseables y, a escala mundial, se está posicionando como una fruta de alta calidad y deseabilidad en el mercado. Sin embargo, después de más de cuarenta años de desarrollo, los huertos de Ataúlfo están siendo afectados por problemas de biología reproductiva que están causando falta de prendimiento y aborto de flores y frutas. En huertos donde se llegaron a producir más de 15 toneladas de fruta por hectárea, ahora se cosechan menos de cuatro. Se hizo una revisión exhaustiva de trabajos de investigación en diversas partes del mundo lo cual genera una hipótesis sobre las posibles causas del fenómeno del “mango niño” y del mango “partenocárpico”, así como de la caída prematura de flores y frutos. Se discute también la posibilidad de una incompatibilidad alo- y endogámica de la variedad Ataúlfo. Todos estos fenómenos parecen estar relacionados con cambios en la temperatura y precipitación en el área, causados por prácticas inapropiadas de cultivo en épocas anteriores y por fenómenos globales, como la incidencia de huracanes y el calentamiento global.  Finalmente, se hacen recomendaciones para desarrollar líneas de investigación que resuelvan estos

    We examined the personal challenges older women faced as they began to rebuild their sense of self after Hurricane Katrina. In-depth interviews with 74 older women approximately 6 months after the disaster revealed challenges in four domains: maintaining social connections, family connections but loss of independence, reestablishing a sense of place, and managing their own health or the health of a loved one. Follow-up data gathered several months after the initial interviews from 21 of the older women indicated that feelings of displacement persisted as they dealt with health concerns, found a place to live, and managed family roles.

    Soil samples were collected along a north-south transect extending from Manitoba, Canada, to the US-Mexico border near El Paso, Texas in 2004 (104 samples), a group of sites within New Orleans, Louisiana following Hurricane Katrina in 2005 (19 samples), and a Gulf Coast transect extending from Sulphur, Louisiana, to DeFuniak Springs, Florida, in 2007 (38 samples). Samples were collected from the top 40 cm of soil and were screened for the presence of total Bacillus species and Bacillus anthracis (anthrax), specifically using multiplex-polymerase chain reaction (PCR). Using an assay with a sensitivity of ~170 equivalent colony-forming units (CFU) g-1 field moist soil, the prevalence rate of Bacillus sp./B. anthracis in the north-south transect and the 2005 New Orleans post-Katrina sample set were 20/5% and 26/26%, respectively. Prevalence in the 2007 Gulf Coast sample set using an assay with a sensitivity of ~4 CFU g-1 of soil was 63/0%. Individual transect-set data indicate a positive relation between occurrences of species and soil moisture or soil constituents (i.e., Zn and Cu content). The 2005 New Orleans post-Katrina data indicated that B. anthracis is readily detectable in Gulf Coast soils following flood events. The data also indicated that occurrence, as it relates to soil chemistry, may be confounded by flood-induced dissemination of germinated cells and the mixing of soil constituents for short temporal periods following an event.

    2008-01-01

    Misconceptions about disasters and their social and health consequences remain prevalent despite considerable research evidence to the contrary. Eight such myths and their factual counterparts were reviewed in a classic report on the public health impact of disasters by Claude de Ville de Goyet entitled, The Role of WHO in Disaster Management: Relief, Rehabilitation, and Reconstruction (Geneva, World Health Organization, 1991), and two additional myths and facts were added by Pan American Health Organization. In this article, we reconsider these myths and facts in relation to Hurricane Katrina, with particular emphasis on psychosocial needs and behaviors, based on data gleaned from scientific sources as well as printed and electronic media reports. The review suggests that preparedness plans for disasters involving forced mass evacuation and resettlement should place a high priority on keeping families together--and even entire neighborhoods, where possible--so as to preserve the familiar and thereby minimize the adverse effects of separation and major dislocation on mental and physical health.

    2014-01-01

    In the aftermath of Hurricane Katrina, which devastated the city of New Orleans in August 2005, restoration workers were at risk for respiratory illness from exposure to airborne particles and microbial agents. In support of an epidemiologic investigation of this risk, an exposure assessment for restoration work activities (demolition, trash & debris management, landscape restoration, sewer/waterline repair, and mold remediation) was performed from 2005 to 2012. For 2005 and 2006, Occupational Safety and Health Administration (OSHA) data (n = 730) for personal and area monitoring of total and respirable dust exposures of restoration workers were accessed and analyzed. The most significant exposures were for demolition work, with average respirable dust exposures in 2005 above the action level of 2.5 mg/m(3) and 17.6% of exposures exceeding the permissible exposure limit (PEL) (5 mg/m(3)). Additional personal and area monitoring for thoracic particulate matter was performed from 2007 to 2012 (n = 774) and samples were assayed for endotoxin and (1→3, 1→6)-β-D-glucan (n = 202). In order to integrate the OSHA data with the later monitoring data, three independent predictive models were developed to convert total and respirable dust measures into the equivalent thoracic dust. The three models were not statistically different and the modeling results were in good agreement with an overall coefficient of variation of 16% for the thoracic dust means across work activities estimated by each of the three models. Overall, thoracic dust exposure levels decreased by about an order of magnitude within the first year after Katrina and then more gradually declined and stabilized through 2012. Estimated average exposures to endotoxin and microbial glucan in 2005 were as high as 256 EU/m(3) and 118 μg/m(3), respectively, and likewise were seen to decrease dramatically and stabilize after 2005. The results of this exposure assessment support previously published reports of

    Using art as a process to help children externalize complex feelings can add another layer of assessment in the primary care setting. In the face of trauma, drawing may help children gain symbolic control over events that are confusing and frightening. Through examples of children who were affected by Hurricane Katrina, this article describes the use of drawings and narratives to understand children's experiences related to traumatic displacement. Recommendations include using a developmental lens to understanding children's art, asking children to talk about their drawings, and considering the significance of place for children who have been traumatically displaced.

    The US Air Force has had a long history of aerial applications of pesticides to fulfill a variety of missions, the most important being the protection of troops through the minimization of arthropod vectors capable of disease transmission. Beginning in World War II, aerial application of pesticides by the military has effectively controlled vector and nuisance pest populations in a variety of environments. Currently, the military aerial spray capability resides in the US Air Force Reserve (USAFR), which operates and maintains C-130 airplanes capable of a variety of missions, including ultra low volume applications for vector and nuisance pests, as well as higher volume aerial applications of herbicides and oil-spill dispersants. The USAFR aerial spray assets are the only such fixed-wing aerial spray assets within the Department of Defense. In addition to troop protection, the USAFR Aerial Spray Unit has participated in a number of humanitarian/relief missions, most recently in the response to the 2005 Hurricanes Katrina and Rita, which heavily damaged the Gulf Coasts of Louisiana, Mississippi, and Texas. This article provides historical background on the Air Force Aerial Spray Unit and describes the operations in Louisiana in the aftermath of Hurricane Katrina.

    Community resilience activities were assessed in workplace teams that became first responders for Hurricane Katrina survivors. Community resilience was assessed by a survey, focus groups, and key informant interviews. On the survey, 90 first responders ranked their team's disaster response performance as high on community resilience activities. The same participants, interviewed in 11 focus groups and 3 key informant interviews, discussed how their teams engaged in community resilience activities to strengthen their ability to deliver services. Specifically, their resilient behaviors were characterized by: shared organizational identity, purpose, and values; mutual support and trust; role flexibility; active problem solving; self-reflection; shared leadership; and skill building. The implications for research, policy, practice, and education of professionals are discussed. © 2011 American Orthopsychiatric Association.

    Catastrophic disasters often are associated with massive structural, economic, and population devastation; less understood are the long-term mental health consequences. This study measures the prevalence and predictors of mental health distress and disability of hurricane survivors over an extended period of recovery in a postdisaster setting. A representative sample of 1077 displaced or greatly affected households was drawn in 2006 using a stratified cluster sampling of federally subsidized emergency housing settings in Louisiana and Mississippi, and of Mississippi census tracts designated as having experienced major damage from Hurricane Katrina in 2005. Two rounds of data collection were conducted: a baseline face-to-face interview at 6 to 12 months post-Katrina, and a telephone follow-up at 20 to 23 months after the disaster. Mental health disability was measured using the Medical Outcome Study Short Form 12, version 2 mental component summary score. Bivariate and multivariate analyses were conducted examining socioeconomic, demographic, situational, and attitudinal factors associated with mental health distress and disability. More than half of the cohort at both baseline and follow-up reported significant mental health distress. Self-reported poor health and safety concerns were persistently associated with poorer mental health. Nearly 2 years after the disaster, the greatest predictors of poor mental health included situational characteristics such as greater numbers of children in a household and attitudinal characteristics such as fatalistic sentiments and poor self-efficacy. Informal social support networks were associated significantly with better mental health status. Housing and economic circumstances were not independently associated with poorer mental health. Mental health distress and disability are pervasive issues among the US Gulf Coast adults and children who experienced long-term displacement or other serious effects as a result of Hurricanes

    2016-01-01

    Full Text Available On August 29th of 2005, Hurricane Katrina hit the gulf coast of the United States leading to one of the most powerful disasters in history. Damage costs reached more than 100 billion dollars, as well as 150,000 flooded houses and 1,330 deaths. 10 years later, the damage remains visible in the city of New Orleans, and the rate of recovery is highly varied throughout different neighborhoods in the city. A popular idea is to associate this to the neighborhood social class, i.e. the poorer an area is, the more difficult the recovery process is. However the reality is more complex. This study looks at two economically similar and highly damaged neighborhoods, with two deeply different recoveries. The Lower 9th Ward, an isolated, and poor neighborhood surrounded by water with the Mississippi River and the industrial canal, has experienced an extremely slow recovery. However, in the isolated and relatively poor neighborhood known as Village de l’Est, located on former marshes at the edge of the city between Lake Pontchartrain and the Bayou Bienvenue, the Vietnamese community ties and cohesion have brought the neighborhood back to fruition faster than anyone would have expected. Despite many common features weakening their technical resilience, such as relatively modern and fast urbanization on former natural and low lands protected mostly by levees, their radically different reaction following Katrina points out the key role of social resilience. This communication will aim to present decisive social aspects of resilience aside from geophysical and physical features such as risk awareness, social link and community culture.

    This study assesses the public health functions played by news information and social capital in the context of Hurricane Katrina. In-depth interviews were conducted with 57 hurricane shelter residents between 4 and 6 weeks after the hurricane. Depression was more common for participants who relied more on news information than for other participants after the hurricane (adjusted odds ratio [AOR], 5.49; 95% CI, 1.29 to 23.35; p=.021). Depression was more common for participants with relatively low levels of pre-hurricane positive social interactions (AOR, .16; 95% CI, .02 to 1.83; p=.046) and post-hurricane positive social interactions (AOR, .02; 95% CI, .00 to .74; p=.033) and high levels of post-hurricane negative social interactions (AOR, 17.05; 95% CI, .92 to 315.64; p=.047). Illness and injury were more common for participants who had relied more on news information than for other participants after the hurricane (AOR, 1.13; 95% CI, 1.02 to 2.77; p=.046).

    The impacts of major tropical storms events on coastal waters include sediment resuspension, intense water column mixing, and increased delivery of terrestrial materials into coastal waters. We examined satellite imagery acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) ocean color sensor aboard the Aqua spacecraft following two major hurricane events: Hurricane Katrina, which made landfall on 29 August 2005, and Hurricane Rita, which made landfall on 24 September. MODIS Aqua true color imagery revealed high turbidity levels in shelf waters immediately following the storms indicative of intense resuspension. However, imagery following the landfall of Katrina showed relatively rapid return of shelf water mass properties to pre-storm conditions. Indeed, MODIS Aqua-derived estimates of diffuse attenuation at 490 nm (K_490) and chlorophyll (chlor_a) from mid-August prior to the landfall of Hurricane Katrina were comparable to those observed in mid-September following the storm. Regions of elevated K_490 and chlor_a were evident in offshore waters and appeared to be associated with cyclonic circulation (cold-core eddies) identified on the basis of sea surface height anomaly (SSHA). Imagery acquired shortly after Hurricane Rita made landfall showed increased water column turbidity extending over a large area of the shelf off Louisiana and Texas, consistent with intense resuspension and sediment disturbance. An interannual comparison of satellite-derived estimates of K_490 for late September and early October revealed relatively lower levels in 2005, compared to the mean for the prior three years, in the vicinity of the Mississippi River birdfoot delta. In contrast, levels above the previous three year mean were observed off Texas and Louisiana 7-10 d after the passage of Rita. The lower values of K_490 near the delta could be attributed to relatively low river discharge during the preceding months of the 2005 season. The elevated levels off Texas and

    A previous study of Hurricane Katrina survivors found that higher levels of predisaster social support were associated with lower psychological distress one year after the storm, and that this pathway was mediated by lower exposure to hurricane-related stressors. As a follow-up, we examined the impact of pre- and postdisaster social support on longer-term of mental health-both psychological distress and posttraumatic stress. In this three-wave longitudinal study, 492 residents in the region affected by Hurricane Katrina reported levels of perceived social support and symptoms of psychological distress prior to the storm (Wave 1). Subsequently, one year after Hurricane Katrina (Wave 2), they reported levels of exposure, perceived social support, and symptoms of psychological distress and posttraumatic stress. The latter three variables were assessed again four years after the hurricane (Wave 3). Results of mediation analysis indicated that levels of exposure to hurricane-related stressors mediated the relationship between Wave 1 perceived social support and Wave 3 psychological distress as well as postdisaster posttraumatic stress. Results of regression analyses indicated that, controlling for Wave 1 psychological distress and disaster exposure, Wave 2 perceived social support was associated with Wave 2 and Wave 3 psychological distress but not posttraumatic stress. Our results confirmed the social causation processes of social support and suggest that posttraumatic stress might not stem directly from the lack of social support. Rather, preexisting deficits in social resources might indirectly affect longer-term posttraumatic stress and general psychological distress by increasing risk for disaster-related stressors.

    Hurricane Katrina, which struck the Gulf Coast of the United States in August 2005, exposed area residents to trauma and extensive property loss. However, little is known about the long-run effects of the hurricane on the mental health of those who were exposed. This study documents long-run changes in mental health among a particularly vulnerable group—low income mothers—from before to after the hurricane, and identifies factors that are associated with different recovery trajectories. Longi...

    Police officers in the New Orleans geographic area faced a number of challenges following Hurricane Katrina. This cross-sectional study examined the effect of social support, gratitude, resilience and satisfaction with life on symptoms of depression. A total of 86 male and 30 female police officers from Louisiana participated in this study. Ordinary least-square (OLS) regression mediation analysis was used to estimate direct and indirect effects between social support, gratitude, resilience, satisfaction with life and symptoms of depression. All models were adjusted for age, alcohol intake, military experience and an increase in the number of sick days since Hurricane Katrina. Mean depressive symptom scores were 9.6 ± 9.1 for females and 10.9 ± 9.6 for males. Mediation analyses indicates that social support and gratitude are directly associated with fewer symptoms of depression. Social support also mediated the relationships between gratitude and depression, gratitude and satisfaction with life, and satisfaction with life and depression. Similarly, resilience mediated the relationship between social support and fewer symptoms of depression. Social support, gratitude and resilience are associated with higher satisfaction with life and fewer symptoms of depression. Targeting and building these factors may improve an officer's ability to address symptoms of depression.

    Full Text Available The impacts of major tropical storms events on coastal waters include sediment resuspension, intense water column mixing, and increased delivery of terrestrial materials into coastal waters. We examined satellite imagery acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS ocean color sensor aboard the Aqua spacecraft following two major hurricane events: Hurricane Katrina, which made landfall on 29 August 2005, and Hurricane Rita, which made landfall on 24 September. MODIS Aqua true color imagery revealed high turbidity levels in shelf waters immediately following the storms indicative of intense resuspension. However, imagery following the landfall of Katrina showed relatively rapid return of shelf water mass properties to pre-storm conditions. Indeed, MODIS Aqua-derived estimates of diffuse attenuation at 490 nm (K_490 and chlorophyll (chlor_a from mid-August prior to the landfall of Hurricane Katrina were comparable to those observed in mid-September following the storm. Regions of elevated K_490 and chlor_a were evident in offshore waters and appeared to be associated with cyclonic circulation (cold-core eddies identified on the basis of sea surface height anomaly (SSHA. Imagery acquired shortly after Hurricane Rita made landfall showed increased water column turbidity extending over a large area of the shelf off Louisiana and Texas, consistent with intense resuspension and sediment disturbance. An interannual comparison of satellite-derived estimates of K_490 for late September and early October revealed relatively lower levels in 2005, compared to the mean for the prior three years, in the vicinity of the Mississippi River birdfoot delta. In contrast, levels above the previous three year mean were observed off Texas and Louisiana 7-10 d after the passage of Rita. The lower values of K_490 near the delta could be attributed to relatively low river discharge during the preceding months of the 2005 season. The elevated levels

    Hurricane Katrina hit southwestern Mississippi on August 29, 2005, at 9:45 a.m. CDT as a category 3 storm with surges up to approx. 9 m and sustained winds of approx. 120 mph. The hurricane's wind, rain, and flooding devastated several coastal towns, from New Orleans through Mobile. The storm also caused significant damage to infrastructure and vegetation of NASA's SSC (Stennis Space Center). Storm recovery at SSC involved not only repairs of critical infrastructure but also forest damage mitigation (via timber harvests and control burns to reduce fire risk). This presentation discusses an effort to use commercially available high spatial resolution multispectral IKONOS data for vegetation damage assessment, based on data collected over SSC on September 2, 2005.

    2009-01-01

    Hurricane Katrina made landfall with the northern Gulf Coast on August 29, 2005, as one of the strongest hurricanes on record. The storm damage incurred in Louisiana included a number of levee failures that led to the inundation of approximately 85 percent of the metropolitan New Orleans area. Whereas extreme levels of storm damage were expected from such an event, the catastrophic failure of the New Orleans levees prompted a quick mobilization of engineering experts to assess why and how particular levees failed. As part of this mobilization, civil engineering members of the United States Geological Survey (USGS) performed terrestrial lidar topographic surveys at major levee failures in the New Orleans area. The focus of the terrestrial lidar effort was to obtain precise measurements of the ground surface to map soil displacements at each levee site, the nonuniformity of levee height freeboard, depth of erosion where scour occurred, and distress in structures at incipient failure. In total, we investigated eight sites in the New Orleans region, including both earth and concrete floodwall levee breaks. The datasets extend from the 17th Street Canal in the Orleans East Bank area to the intersection of the Gulf Intracoastal Waterway (GIWW) with the Mississippi River Gulf Outlet (MRGO) in the New Orleans East area. The lidar scan data consists of electronic files containing millions of surveyed points. These points characterize the topography of each levee's postfailure or incipient condition and are available for download through online hyperlinks. The data serve as a permanent archive of the catastrophic damage of Hurricane Katrina on the levee systems of New Orleans. Complete details of the data collection, processing, and georeferencing methodologies are provided in this report to assist in the visualization and analysis of the data by future users.

    During the last four years, significant effort has been devoted to understanding the effects that Hurricanes Katrina and Rita had on contaminant distribution and redistribution in New Orleans, Louisiana, USA, and the surrounding Gulf Coast area. Elevated concentrations were found for inorganic contaminants (including As, Fe, Pb, and V), several organic pollutants (polycyclic aromatic hydrocarbons, pesticides, and volatiles) and high concentration of bioaerosols, particularly Aeromonas and Vibrio. Data from different research groups confirm that some contaminant concentrations are elevated, that existing concentrations are similar to historical data, and that contaminants such as Pb and As may pose human health risks. Two data sets have been compiled in this article to serve as the foundation for preliminary risk assessments within greater New Orleans. Research from the present study suggests that children in highly contaminated areas of New Orleans may experience Pb exposure from soil ranging from 1.37 microg/d to 102 microg/d. These data are critical in the evaluation of children's health. Copyright (c) 2010 SETAC.

  8. Dissolved and colloidal trace elements in the Mississippi River delta outflow after Hurricanes Katrina and Rita

    The Mississippi River delta outflow region is periodically disturbed by tropical weather systems including major hurricanes, which can terminate seasonal bottom water hypoxia and cause the resuspension of shelf bottom sediments which could result in the injection of trace elements into the water column. In the summer of 2005, Hurricanes Katrina and Rita passed over the Louisiana Shelf within a month of each other. Three weeks after Rita, we collected water samples in the Mississippi River delta outflow, examining the distributions of trace elements to study the effect of Hurricanes Katrina and Rita. We observed limited stratification on the shelf and bottom waters that were no longer hypoxic. This resulted, for instance, in bottom water dissolved Mn being lower than is typically observed during hypoxia, but with concentrations still compatible with Mn-O2 trends previously reported. Interestingly, for no element were we able to identify an obvious effect of sediment resuspension on its distribution. In general, elemental distributions were compatible with previous observations in the Mississippi outflow system. Co and Re, which have not been reported for this system previously, showed behavior consistent with other systems: input for Co likely from desorption and conservative mixing for Re. For Cs, an element for which there is little information regarding its estuarine behavior, conservative mixing was also observed. Our filtration method, which allowed us to distinguish the dissolved (<0.02 μm) from colloidal (0.02-0.45 μm) phase, revealed significant colloidal fractions for Fe and Zn, only. For Fe, the colloidal phase was the dominant fraction and was rapidly removed at low salinity. Dissolved Fe, in contrast, persisted out to mid-salinities, being removed in a similar fashion to nitrate. This ability to distinguish the smaller Fe (likely dominantly organically complexed) from larger colloidal suspensates may be useful in better interpreting the bioavailablity

    We examined health-related quality of life in adults in the Louisiana Health Aging Study (LHAS) after Hurricanes Katrina and Rita (HK/R) that made landfall on the U.S. Gulf Coast region in 2005. Analyses of pre- and post-disaster SF-36 scores yielded changes in physical function and bodily pain. Mental health scores were lower for women than men. Gender differences were observed in religious beliefs and religious coping, favoring women. Religious beliefs and religious coping were negatively correlated with physical function, implying that stronger reliance on religiosity as a coping mechanism may be more likely among those who are less physically capable.

    The purpose of this study was to: (1) explore experiences and responses of staff in caring for sheltered, frail, Hurricane Katrina evacuees; and (2) identify how planning and training can be enhanced for staff who may care for frail older populations during and after disasters. Individual, in-person, semi-structured interviews were conducted with 38 staff members in four nursing homes in Mississippi, sheltering 109 evacuees in November 2005, nine weeks after Hurricane Katrina. Twenty-four were direct care staff, including certified nursing assistants, licensed nurses, dietary aides, and social workers; 14 were support staff, including maintenance and business managers. The number interviewed in each nursing home averaged 9.5 (range 6-15). Using a discussion guide and focusing on their experiences caring for nursing home evacuees, staff were asked to describe: (1) experiences; (2) problems; (3) what helped; and (4) what was learned. Data were processed using grounded theory and thematic analysis. Responses of direct care staff differed in emphasis from those of support staff in several areas; responses from these groups were analyzed separately and together. Three of the researchers identified recurring themes; two organized themes conceptually. Staff emphasized providing emotional reassurance to evacuees as well as physical care. Many described caring for evacuees as "a blessing," saying the experience helped them bond with residents, evacuees, and other staff. However, caring for evacuees was difficult because staff members were extremely anxious and in poor physical condition after an arduous evacuation. Challenges included communicating with evacuees' families, preventing dehydration, lack of personal hygiene supplies, staff exhaustion, and emotional needs of residents, evacuees, and staff. Teamwork, community help, and having a well-organized disaster plan, extra supplies, and dependable staff helped personnel cope with the situation. Staff of nursing homes

    To explore the effects of hurricane exposure and forced relocation on the mind and body, we compared psychiatric diagnoses and symptoms with heart rate variability (HRV) for 34 relocated Katrina survivors and 34 demographically matched controls. All participants were healthy and free of psychiatric and cardiovascular medications. We measured symptoms of posttraumatic stress disorder (PTSD) (Clinician-Administered PTSD Scale 1) and depression (Beck Depression Inventory), Axis I psychiatric diagnoses (Structured Clinical Interview for DSM-IV), psychosocial disability (Sheehan Disability Scale), and power spectral analysis HRV reactivity to trauma reminders. Katrina-related PTSD occurred in 38% of survivors and 12% of controls. Survivors reported higher levels of PTSD and depression symptoms, within diagnostic ranges, and greater psychosocial disability than controls. Survivors had higher resting heart rate (80.82 [standard deviation = 13.60] versus 74.85 [10.67], p = .05), lower parasympathetic (high-frequency [HF] normalized unit) baseline HRV activity (40.14 [23.81] versus 50.67 [19.93], p = .04) and less reactivity with trauma cues (-2.63 [20.70] versus -11.96 [15.84], p = .04), and higher baseline sympathovagal activity (low frequency/HF ratio) (2.84 [3.08] versus 1.35 [1.08], p = .04) than controls. Survivors with depression (n = 12) and with depression and PTSD combined (n = 7), but not those with PTSD (n = 13), had flattened parasympathetic responsiveness to trauma cues. HRV indices correlated with depressive (low frequency/HF, p = .01; HF normalized unit, p = .046) but not PTSD symptoms (p values > .05). Results showed this multilayer trauma's impact on emotional health and HRV-based measures of autonomic nervous system dysregulation. Specifically, dysregulation of depressed survivors' HRV in response to trauma reminders supports more autonomic involvement in traumatic loss/depression than in PTSD. Diagnostic criteria for PTSD include physiologic reactivity

    Full Text Available By providing a wide literature review, post-hurricane Katrina uneven urban regeneration in New Orleans is presented here by framing it within a historical perspective in order to underline how environmental threats too often seem to be not so much “natural” but rather man-made as well as to highlight both the reasons and the ways in which, in post-disaster reconstruction, competitive growth has been valued over equity, by directly benefiting those who were already the most advantaged. The aim is to highlight how environmental disasters can be considered as socially constructed phenomena, as they cannot be seen as a single event but rather as a process made by a series of progressive steps occurring within different spheres, which do not necessarily concern the environment only.

    Substance use disorders are credited with greater amounts of death and illness than all other preventable health problems. Billions of dollars are spent on efforts to control drug supplies and fund various treatment approaches, but relatively little resources have been directed towards investigating how environmental conditions can contribute to or detract from substance user's individual motivation to change behavior. Hurricane Katrina caused untold property damage and upheaval, in addition to the vast numbers of people whose lives it drastically affected. This article examines how surviving this ordeal, subsequent evacuation, and eventual resettlement in New Orleans or re-location to a different city (in this case, Houston) impacted individuals' motivation to change their substance use patterns and behaviors. This article's approach is grounded in the values of the social work profession and examines: 1) the role of life events in motivating change of substance using behaviors in the absence of formal treatment interventions; and 2) participant resilience in overcoming the adversities inherent to this disaster.

    McNamara, D.; Werner, B.; Kelso, A.

    2005-12-01

    Motivated by destruction in New Orleans following hurricane Katrina, we use a numerical model to explore how natural processes, economic development, hazard mitigation measures and policy decisions intertwine to produce long periods of quiescence punctuated by disasters of increasing magnitude. Physical, economic and policy dynamics are modeled on a grid representing the subsiding Mississippi Delta region surrounding New Orleans. Water flow and resulting sediment erosion and deposition are simulated in response to prescribed river floods and storms. Economic development operates on a limited number of commodities and services such as agricultural products, oil and chemical industries and port services, with investment and employment responding to both local conditions and global constraints. Development permitting, artificial levee construction and pumping are implemented by policy agents who weigh predicted economic benefits (tax revenue), mitigation costs and potential hazards. Economic risk is reduced by a combination of private insurance, federal flood insurance and disaster relief. With this model, we simulate the initiation and growth of New Orleans coupled with an increasing level of protection from a series of flooding events. Hazard mitigation filters out small magnitude events, but terrain and hydrological modifications amplify the impact of large events. In our model, "natural disasters" are the inevitable outcome of the mismatch between policy based on short-time-scale economic calculations and stochastic forcing by infrequent, high-magnitude flooding events. A comparison of the hazard mitigation response to river- and hurricane-induced flooding will be discussed. Supported by NSF Geology and Paleontology and the Andrew W Mellon Foundation.

    In a disaster, social service workers are often survivors themselves.This study examines whether somatic intervention using a brief (one to two session) stabilization model now called the Trauma Resiliency Model (TRM), which uses the skills of Somatic Experiencing (SE), can reduce the postdisaster symptoms of social service workers involved in postdisaster service delivery.The study was implemented with a nonrandom sample of 142 social service workers who were survivors of Hurricanes Katrina and Rita in New Orleans and Baton Rouge, Louisiana, two to three months after the disasters. Ninety-one participants received SE/TRM and were compared with a matched comparison group of 51 participants through the use of propensity score matching. All participants first received group psychoeducation. Results support the benefits of the brief intervention inspired by SE. The treatment group showed statistically significant gains in resiliency indicators and decreases in posttraumatic stress disorder symptoms. Although psychological symptoms increased in both groups at the three to four month follow-up, the treatment group's psychological symptoms were statistically lower than those of the comparison group.

    2011-03-01

    Full Text Available Breaking with the traditional conservatism championed by Ronald Reagan, George W. Bush wanted his social policy to move away from monetary considerations to embrace a religious and spiritual method in healing social ills. The Office of Faith-Based and Community Initiatives, located in the White House, was inaugurated a few days after Bush was sworn in. However, the Office was immediately plagued by internal strife, lack of funding and absence of political commitment. Hurricane Katrina (2005 dealt a serious political blow to the Republican President. But paradoxically, it reinforced the ideological hegemony of faith-based organizations. Indeed, following the relief efforts, faith-based organizations, rather than government, were hailed as effective instruments in the fight against poverty, distress, and deviance. This article will argue that contrary to this perception, faith-based organizations have a limited effect on poverty and that the Bush administration exploited them for political purposes.

    This study seeks to determine the relative influence of race and class on trust in sources of messages of environmental risk in post-Katrina New Orleans. It poses two hypotheses to test that influence: H1-African-Americans ("Blacks") trust risk message sources less than European American ("Whites") do and H2-The higher the socioeconomic class, the lower the trust in risk message sources. A 37-question telephone survey (landlines and cellphones) was conducted in Orleans Parish in 2012 (n = 414). The overall margin of error was ±4.8% at a 95% confidence interval. A hierarchical regression analysis revealed that the first hypothesis was rejected, while the second was supported. Additional data analysis revealed that frequency of use of sources of risk information appears to be a positive factor in building trust. © The Author(s) 2015.

    Since September 2005, Charity Hospital of New Orleans has been closed due to Hurricane Katrina. A debate following the closing arose about whether this public hospital should be renovated or a new medical center affiliated with the Louisiana State University should be built. Using academic literature, government statistics, and popular press reports, we describe the economic implications that support the view that Charity Hospital should have been renovated. We also address why this policy was not pursued by demonstrating the influence politics and individual stakeholders (specifically, Louisiana State University) had on the eventual policy pursued. In this commentary we also note the political identity movement away from public-sector provision of services to private-sector interests.

    2011-09-01

    Full Text Available We investigate the impact of trauma on cross-scale interactions in order to identify the major social-ecological factors affecting the pace and trajectory of post-Katrina rebuilding in New Orleans, Louisiana, USA. Disaster and traumatic events create and activate networks and linkages at different spatial and institutional levels to provide information and resources related to post-trauma recovery and rebuilding. The extension, intensification, and acceleration of cross-scale linkages and interactions in response to trauma alter organizational couplings, which then contribute to the vulnerability and resilience of social-ecological systems. Rather than viewing urban ecosystems as either resilient or vulnerable, we conceptualize them as embodying both resilient and vulnerable components. This integrated approach directs analytical attention to the impact of socio-legal regulations, government policies, and institutional actions on resilience and vulnerability, which are also systemic properties of urban ecosystems.

    2011-06-01

    In Louisiana's unique, populist-derived charity health system, the self-designation Charity Hospital Baby expresses situational identity anchored in the life cycle and the inversion of racist and authoritative connotations. This article draws on theoretical perspectives of stratified reproduction and the politics of time to examine the controversy in which Babies advocate reopening the Katrina-damaged New Orleans Charity Hospital, and administrators and planners support a new state-of-the-art biosciences district, GNOBED. Babies evoke the present, ethical urgency (kairos) of responding to sickness and disability; GNOBED implies prolonging or saving future lives through biotechnologies under development in accelerated time (chronos). As preservationists and residents threatened with displacement join "re-open Charity" proponents, planners symbolically engage in prolepsis, rhetorically precluding opposing arguments with flash forward of supposedly "done deals." At stake is nothing less than social death for a segment of this ethnically diverse city. [public

    The objective of this study is to gain insight into the medical needs of disaster evacuees, through a review of experiential data collected in evacuation shelters in the days and weeks following Hurricanes Katrina and Rita in 2005, to better prepare for similar events in the future. Armed with the information and insights provided herein, it is hoped that meaningful precautions and decisive actions can be taken by individuals, families, institutions, communities, and officials should the Louisiana Gulf Coast-or any other area with well-known vulnerabilities-be faced with a future emergency. Demographic and clinical data that were recorded on paper documents during triage and treatment in evacuation shelters were later transcribed into a computerized database management system, with cooperation of the Department of Health Information Management at The University of Louisiana at Lafayette. Analysis of those contemporaneously collected data was undertaken later by the Louisiana Center for Health Informatics. Evacuation shelters, Parish Health Units, and other locations including churches and community centers were the venue for ad hoc clinics in the Acadiana region of Louisiana. The evacuee-patients-3,329 of them-whose information is reflected in the subject dataset were among two geographically distinct but similarly distressed groups: 1) evacuees from Hurricane Katrina that devastated New Orleans and other locales near Louisiana and neighboring states in late August 2005 and 2) evacuees from Hurricane Rita that devastated Southwest Louisiana and neighboring areas of Texas in September 2005. Patient data were collected by physicians, nurses, and other volunteers associated with the Operation Minnesota Lifeline (OML) deployment during the weeks following the events. Volunteer clinicians from OML provided triage and treatment services and documented those services as paper medical records. As the focus of the OML "mission of mercy" was entirely on direct individually

    This prospective study examined the pathways by which religious involvement affected the post-disaster psychological functioning of women who survived Hurricanes Katrina and Rita. The participants were 386 low-income, predominantly Black, single mothers. The women were enrolled in the study before the hurricane, providing a rare opportunity to document changes in mental health from before to after the storm, and to assess the protective role of religious involvement over time. Results of structural equation modeling indicated that, controlling for level of exposure to the hurricanes, pre-disaster physical health, age, and number of children, pre-disaster religiousness predicted higher levels of post-disaster (1) social resources and (2) optimism and sense of purpose. The latter, but not the former, was associated with better post-disaster psychological outcome. Mediation analysis confirmed the mediating role of optimism and sense of purpose. PMID:21626083

    The U.S. Geological Survey (USGS), in collaboration with the Louisiana Department of Environmental Quality, monitored bacteriological quality of water at 22 sites in and around Lake Pontchartrain, La., for three consecutive weeks beginning September 13, 2005, following hurricanes Katrina and Rita and the associated flooding. Samples were collected and analyzed by USGS personnel from the USGS Louisiana Water Science Center and the USGS Ohio Water Microbiology Laboratory. Fecal-indicator bacteria (Escherichia coli, enterococci, and fecal coliform) concentrations ranged from the detection limit to 36,000 colony-forming units per 100 milliliters. Data are presented in tabular form and as plots of data in the context of available historical data and water-quality standards and criteria for each site sampled. Quality-control data were reviewed to ensure that methods performed as expected in a mobile laboratory setting.

    Hospital surge capacity has been advocated to accommodate large increases in demand for healthcare; however, existing urban trauma centers and emergency departments (TC/EDs) face barriers to providing timely care even at baseline patient volumes. The purpose of this study is to describe how alternate-site medical surge capacity absorbed large patient volumes while minimizing impact on routine TC/ED operations immediately after Hurricane Katrina. From September 1 to 16, 2005, an alternate site for medical care was established. Using an off-site space, the Dallas Convention Center Medical Unit (DCCMU) was established to meet the increased demand for care. Data were collected and compared with TC/ED patient volumes to assess impact on existing facilities. During the study period, 23,231 persons displaced by Hurricane Katrina were registered to receive evacuee services in the City of Dallas, Texas. From those displaced, 10,367 visits for emergent or urgent healthcare were seen at the DCCMU. The mean number of daily visits (mean +/- SD) to the DCCMU was 619 +/- 301 visits with a peak on day 3 (n = 1,125). No patients died, 3.2% (n = 257) were observed in the DCCMU, and only 2.9% (n = 236) required transport to a TC/ED. During the same period, the mean number of TC/ED visits at the region's primary provider of indigent care (Hospital 1) was 346 +/- 36 visits. Using historical data from Hospital 1 during the same period of time (341 +/- 41), there was no significant difference in the mean number of TC/ED visits from the previous year (p = 0.26). Alternate-site medical surge capacity provides for safe and effective delivery of care to a large influx of patients seeking urgent and emergent care. This protects the integrity of existing public hospital TC/ED infrastructure and ongoing operations.

Los valores de estos dos parametros, que dependen de la posicion del vortice, corresponden a dos casos: el huracan Hilda que cruzo la parte central del Golfo de Mexico entre el 29 de septiembre y el 3 de octubre de 1964, y el huracan Gilberto cuya trayectoria cruzo, entre el 11 y el 17 de septiembre de 1988, el Mar Caribe, la Peninsula de Yucatan y el suroeste del Golfo de Mexico. Los resultados muestran que vortices ciclonicos con tales caracteristicas producen, durante su paso en el mar, un transporte vertical turbulento de agua a traves de la termoclina que llega a enfriar la capa de mezcla en algunos grados y a incrementar la profundidad de la termoclina en algunos metros, en coincidencia con las observaciones.

    Hurricane Katrina's effect on the population of the City of New Orleans provides a model of how severe weather events, which are likely to increase in frequency and strength as the climate warms, might affect other large coastal cities. Our research focuses on changes in the migration system - defined as the system of ties between Orleans Parish and all other U.S. counties - between the pre-disaster (1999-2004) and recovery (2007-2009) periods. Using Internal Revenue Service county-to-county migration flow data, we find that in the recovery period Orleans Parish increased the number of migration ties with and received larger migration flows from nearby counties in the Gulf of Mexico coastal region, thereby spatially concentrating and intensifying the in-migration dimension of this predominantly urban system, while the out-migration dimension contracted and had smaller flows. We interpret these changes as the migration system relying on its strongest ties to nearby and less damaged counties to generate recovery in-migration.

    An important aspect of crisis counseling is linking survivors with services for their unmet needs. We examined determinants of referrals for disaster relief, additional crisis counseling, and psychological services in 703,000 crisis counseling encounters 3-18 months after Hurricane Katrina. Referrals for disaster relief were predicted by clients' losses, age (adults rather than children), and urbanicity. Referrals for additional counseling and psychological services were predicted by urbanicity, losses and trauma exposure, prior trauma, and preexisting mental health problems. Counseling and psychological referrals declined over time despite continuing mental health needs. Results confirm large urban-rural disparities in access to services.

    Full Text Available Abstract Background Natural disaster is often a cause of psychopathology, and women are vulnerable to post-traumatic stress disorder (PTSD and depression. Depression is also common after a woman gives birth. However, no research has addressed postpartum women's mental health after natural disaster. Methods Interviews were conducted in 2006–2007 with women who had been pregnant during or shortly after Hurricane Katrina. 292 New Orleans and Baton Rouge women were interviewed at delivery and 2 months postpartum. Depression was assessed using the Edinburgh Depression Scale and PTSD using the Post-Traumatic Stress Checklist. Women were asked about their experience of the hurricane with questions addressing threat, illness, loss, and damage. Chi-square tests and log-binomial/Poisson models were used to calculate associations and relative risks (RR. Results Black women and women with less education were more likely to have had a serious experience of the hurricane. 18% of the sample met the criteria for depression and 13% for PTSD at two months postpartum. Feeling that one's life was in danger was associated with depression and PTSD, as were injury to a family member and severe impact on property. Overall, two or more severe experiences of the storm was associated with an increased risk for both depression (relative risk (RR 1.77, 95% confidence interval (CI 1.08–2.89 and PTSD (RR 3.68, 95% CI 1.80–7.52. Conclusion Postpartum women who experience natural disaster severely are at increased risk for mental health problems, but overall rates of depression and PTSD do not seem to be higher than in studies of the general population.

    To examine how the demographic and other population changes affected birth and obstetric outcomes in Louisiana, and the effect of the hurricane on racial disparities in these outcomes. Vital statistics data were used to compare the incidence of low birth weight (LBW) (birth (PTB) (37 weeks' gestation), cesarean section, and inadequate prenatal care (as measured by the Kotelchuck index), in the 2 years after Katrina compared to the 2 years before, for the state as a whole, region 1 (the area around New Orleans), and Orleans Parish (New Orleans). Logistic models were used to adjust for covariates. After adjustment, rates of LBW rose for the state, but preterm birth did not. In region 1 and Orleans Parish, rates of LBW and PTB remained constant or fell. These patterns were all strongest in African American women. Rates of cesarean section and inadequate prenatal care rose. Racial disparities in birth outcomes remained constant or were reduced. Although risk of LBW/PTB remained higher in African Americans, the storm does not appear to have exacerbated health disparities, nor did population shifts explain the changes in birth and obstetric outcomes.

    2010-07-01

    In the aftermath of Hurricane Katrina, the majority of routine activities in New Orleans were disrupted, including the illegal drug market. The large-scale relocation of New Orleans evacuees (NOEs), including many illegal drug users and sellers, to host cities led to a need for new sources of illegal drugs. This need was quickly satisfied by two initially distinct drug markets (1) drug dealers from New Orleans who were themselves evacuees and (2) established drug dealers in the host cities. To be expected, the two markets did not operate indefinitely in parallel fashion. This paper describes the evolving, operational relationship between these two drug markets over time, with a focus on Houston. We analyze the reciprocal evolution of these two markets at two significant points in time: at the beginning of the relocation (2005) and two years later (2007). The overall trend is towards a melding of the two drug markets, as evidenced primarily by decreases in drug-related violence and the cross-fertilization of drug tastes. We describe the process by which the two drug markets are melded over time, in order to seek a better understanding of the social processes by which drug markets in general evolve.

    Hurricanes Katrina and Rita resulted in enormous loss of life and disrupted the delivery of health care in areas affected by them. In causing mass movements of patients, natural disasters can overwhelm the resources of nephrology communities in areas not suffering direct damage. The following largely personal account evaluates the impact these hurricanes had upon the nephrology community, patients and health care providers alike, in areas not directly affected by the storms. Mass evacuation of hundreds of dialysis patients to surrounding areas overwhelmed the capacity of local hemodialysis centers. Non-availability of medical records in patients arriving without a supply of their routine medications led to confusion and sub-optimal treatment of conditions such as hypertension and congestive heart failure. Availability of cadaveric organs for transplantation was reduced in the surrounding areas, as the usual lines of communication and transportation were severed for several weeks. All of these issues led to prolong waiting times for patients on the transplant list. The hurricanes severely disrupted usual supply lines of medications to hospitals; certain rare conditions may be seen in higher numbers as a result of the shortages induced. We present the interesting surge in cases of acute kidney injury secondary to use of intravenous immune globulin.

    Hurricane Katrina caused many individuals to evacuate to towns and cities throughout the United States. Psychological First Aid (PFA) is a treatment program designed to help clinicians and other disaster relief workers address the needs of adults, youth, and families immediately following disasters. We conducted focus groups with disaster relief and evacuee service providers in the Kansas City Metro Area as an exploratory study to identify their perceptions of the needs of evacuees. Participants identified a number of mental health needs, as well as displacement-related challenges, including loss of social support, material loss, unemployment, and other stressful life events that were secondary to the hurricane. Many of these needs are consistent with principles presented in the PFA manual. We also found that service providers faced unique challenges when attempting to assist evacuees. We discuss implications of these findings for treatment programs and provide suggestions for addressing barriers to care.

  18. Creative Coercion in Post-Katrina New Orleans: a Neighborhood Strategy to Address Conflict in Networks

    Directory of Open Access Journals (Sweden)

    Stephen Danley

    2015-03-01

    Full Text Available The study of relationships within networks has traditionally focused on concepts such as cooperation, collaboration and other forms of partnership (Brown & Keast 2003. The assumption has been that actors in a network have shared vision and are working together. This study tests that idea by using mixed methods and ethnography to examine 15 neighborhood associations in post-Katrina New Orleans, and 71 of their relationships within policy networks. Contrary to our typical understanding of networks, neighborhood associations engage not just in partnership, but also in power struggles. When excluded from policy networks, neighborhood associations use creative coercion to ensure their voice is heard. Facing a power deficit, these associations look for informal levers to assert themselves into policy negotiation. The result is creative and coercive measures, such as co-opting elections, bribery, blackmail and what one neighborhood activist calls ‘guerrilla warfare.’ These conflicts force a reconsideration of networks. Networks are not solely homes of collaborative action; they are also the location of sharp power struggles over priorities.

    Approximately 30.2 million litres of oil were discharged during Hurricanes Katrina and Rita. A total of 230 incidents were reported to the state's spill response community, including ruptured pipelines, damaged and moved storage tanks, refineries, and sunken vessels. By January 2006, industry had reported the recovery of 14.7 million litres of oil. After Hurricane Rita, a further 234 off- and onshore incidents were reported. This paper presented a chronology from August 26 2005 through to June 2006 of clean-up activities for both hurricanes, with specific reference to logistic and communications issues associated with working in environments that are difficult to access due to damaged transportation infrastructure. An outline of the Louisiana Oil Spill Coordinator's Office's role in the incidents was presented, as well as an overview of the Louisiana State Contingency Plan. It was noted that the lack of communications systems caused considerable difficulties for responders. It was concluded that responses to hurricanes can be made more effective by having all response communities incident command structure (ICS)-trained with a thorough knowledge of the National Response Plan as it relates to the National Contingency Plan. Ensuring that plans are operational, having clear lines of authority on all hurricane-related issues, and having a robust communications plan were recommended, as well as the ability to respond without communications.

  2. Effects of hurricanes Katrina and Rita on Louisiana black bear habitat

    2012-01-01

    The Louisiana black bear (Ursus americanus luteolus) is comprised of 3 subpopulations, each being small, geographically isolated, and vulnerable to extinction. Hurricanes Katrina and Rita struck the Louisiana and Mississippi coasts in 2005, potentially altering habitat occupied by this federally threatened subspecies. We used data collected on radio-telemetered bears from 1993 to 1995 and pre-hurricane landscape data to develop a habitat model based on the Mahalanobis distance (D2) statistic. We then applied that model to post-hurricane landscape data where the telemetry data were collected (i.e., occupied study area) and where bear range expansion might occur (i.e., unoccupied study area) to quantify habitat loss or gain. The D2 model indicated that quality bear habitat was associated with areas of high mast-producing forest density, low water body density, and moderate forest patchiness. Cross-validation and testing on an independent data set in central Louisiana indicated that prediction and transferability of the model were good. Suitable bear habitat decreased from 348 to 345 km2 (0.9%) within the occupied study area and decreased from 34,383 to 33,891 km2 (1.4%) in the unoccupied study area following the hurricanes. Our analysis indicated that bear habitat was not significantly degraded by the hurricanes, although changes that could have occurred on a microhabitat level would be more difficult to detect at the resolution we used. We suggest that managers continue to monitor the possible long-term effects of these hurricanes (e.g., vegetation changes from flooding, introduction of toxic chemicals, or water quality changes).

    Hurricane Katrina struck an area dense with industry, causing numerous releases of petroleum and hazardous materials. This study integrates information from a number of sources to describe the frequency, causes, and effects of these releases in order to inform analysis of risk from future hurricanes. Over 200 onshore releases of hazardous chemicals, petroleum, or natural gas were reported. Storm surge was responsible for the majority of petroleum releases and failure of storage tanks was the most common mechanism of release. Of the smaller number of hazardous chemical releases reported, many were associated with flaring from plant startup, shutdown, or process upset. In areas impacted by storm surge, 10% of the facilities within the Risk Management Plan (RMP) and Toxic Release Inventory (TRI) databases and 28% of SIC 1311 facilities experienced accidental releases. In areas subject only to hurricane strength winds, a lower fraction (1% of RMP and TRI and 10% of SIC 1311 facilities) experienced a release while 1% of all facility types reported a release in areas that experienced tropical storm strength winds. Of industrial facilities surveyed, more experienced indirect disruptions such as displacement of workers, loss of electricity and communication systems, and difficulty acquiring supplies and contractors for operations or reconstruction (55%), than experienced releases. To reduce the risk of hazardous material releases and speed the return to normal operations under these difficult conditions, greater attention should be devoted to risk-based facility design and improved prevention and response planning.

    Floodwaters in New Orleans from Hurricanes Katrina and Rita were observed to contain high levels of fecal indicator bacteria and microbial pathogens, generating concern about long-term impacts of these floodwaters on the sediment and water quality of the New Orleans area and Lake Pontchartrain. We show here that fecal indicator microbe concentrations in offshore waters from Lake Pontchartrain returned to prehurricane concentrations within 2 months of the flooding induced by these hurricanes. Vibrio and Legionella species within the lake were more abundant in samples collected shortly after the floodwaters had receded compared with samples taken within the subsequent 3 months; no evidence of a long-term hurricane-induced algal bloom was observed. Giardia and Cryptosporidium were detected in canal waters. Elevated levels of fecal indicator bacteria observed in sediment could not be solely attributed to impacts from floodwaters, as both flooded and nonflooded areas exhibited elevated levels of fecal indicator bacteria. Evidence from measurements of Bifidobacterium and bacterial diversity analysis suggest that the fecal indicator bacteria observed in the sediment were from human fecal sources. Epidemiologic studies are highly recommended to evaluate the human health effects of the sediments deposited by the floodwaters.

    To assess the extent to which Hurricanes Katrina and Rita affected polycyclic aromatic hydrocarbons (PAH) in the Gulf of Mexico (GOM), sediment cores were analyzed in late 2005 from: a shallow shelf, a deeper shelf, and a marsh station. Sediment geochronology, fabric, and geochemistry show that the 2005 storms deposited approximately 10cm of sediment to the surface of a core at 5-12A. Bulk carbon geochemistry and PAH isomers in this top layer suggest that the source of sediment to the top portion of core 5-12A was from a relatively more marine area. Particulate PAHs in the marsh core (04M) appeared unaffected by the storms while sediments in the core from Station 5-1B (deeper shelf) were affected minimally (some possible storm-derived deposition). Substantial amounts of PAH-laden particles may have been displaced from the seabed in shallow areas of the water column in the GOM by these 2005 storms.

    Sediment samples were collected from two homes which were flooded in the wake of Hurricane Katrina in August 2005. The samples were analyzed for trace metals and semi-volatile organic compounds using techniques based on established EPA methods. The data showed higher concentrations of some metals and semi-volatile organic pollutants than reported in previous outdoor sampling events of soils and sediments. The Lake Pontchartrain sediments became resuspended during the hurricane, and this material subsequently was found in the residential areas of New Orleans following levee breaches. The clay and silt particles appear to be selectively deposited inside homes, and sediment contaminant concentrations are usually greatest within this fraction. Re-entry advisories based on outdoor sample concentration results may have under-predicted the exposure levels to homeowners and first responders. All contaminants found in the sediment sampled in this study have their origin in the sediments of Lake Pontchartrain and other localized sources.

    Samples of street mud, suspended and bottom sediment in canals discharging to Lake Ponchartrain, and suspended and bottom sediment in the lake were collected and analyzed for chemical constituents to help evaluate the effects of Hurricanes Katrina and Rita and the subsequent unwatering of New Orleans, Louisiana. The approach used for sampling and analysis of chemical data for the study is presented herein. Radionuclides, major and trace elements, and numerous organic compounds in sediment were analyzed. The organic compounds include organochlorine pesticides, polychlorinated biphenyls, polycyclic aromatic hydrocarbons, urban waste indicator compounds, and current-use pesticides. Methods for the analysis of urban waste indicator compounds and current-use pesticides in sediment were developed only recently.

  9. Hurricanes Katrina and Rita and the Department of Veterans Affairs: a conceptual model for understanding the evacuation of nursing homes.

    Hurricanes Katrina and Rita exposed significant flaws in US preparedness for catastrophic events and the nation's capacity to respond to them. These flaws were especially evident in the affected disaster areas' nursing homes, which house a particularly vulnerable population of frail older adults. Although evacuation of a healthcare facility is a key preparedness activity, there is limited research on factors that lead to effective evacuation. Our review of the literature on evacuation is focused on developing a conceptual framework to study future evacuations rather than as a comprehensive assessment of prior work. This paper summarizes what is known thus far about disaster response activities of nursing homes following natural and human-caused disasters, describes a conceptual model to guide future inquiry regarding this topic, and suggests future areas of research to further understand the decision-making process of nursing home facilitators regarding evacuating nursing home residents. To demonstrate the utility of the conceptual model and to provide guidance about effective practices and procedures, this paper focuses on the responses of Veterans Health Administration (VHA) nursing homes to the 2 hurricanes. Quarantelli's conceptual framework, as modified by Perry and Mushkatel, is useful in guiding the development of central hypotheses related to the decision-making that occurred in VA nursing homes and other healthcare facilities following Hurricanes Katrina and Rita. However, we define evacuation somewhat differently to account for the fact that evacuation may, in some instances, be permanent. Thus, we propose modifying this framework to improve its applicability beyond preventive evacuation. We need to better understand how disaster plans can be adapted to meet the needs of frail elders and other residents in nursing homes. Moreover, we must address identified gaps in the scientific literature with respect to health outcomes by tracking outcomes over time

    Disaster responders work among poorly characterized physical and psychological hazards with little understood regarding health consequences of their work. A survey administered to 2834 US Coast Guard responders to Hurricanes Katrina and Rita provided data on exposures and health effects. Prevalence odds ratios (PORs) evaluated associations between baseline characteristics, missions, exposures, and health effects. Most frequent exposures were animal/insect vector (n = 1309; 46%) and floodwater (n = 817; 29%). Most frequent health effects were sunburn (n = 1119; 39%) and heat stress (n = 810; 30%). Significant positive associations were for mold exposure and sinus infection (POR = 10.39); carbon monoxide and confusion (POR = 6.27); lack of sleep and slips, trips, falls (POR = 3.34) and depression (POR = 3.01); being a Gulf-state responder and depression (POR = 3.22). Increasing protection for disaster responders requires provisions for adequate sleep, personal protective equipment, and access to medical and psychological support.

    We provide information about the effects of Hurricane Katrina on populations of an invasive fish, the Nile tilapia (Oreochromis niloticus) in southern Mississippi. By resampling areas surveyed before the storm, we attempted to determine whether the species expanded its range by moving with storm-related floods. Additionally, we used rotenone to eradicate individuals of this species at a hurricane-damaged aquaculture facility on the Mississippi coast. Although our survey was limited geographically, we did not find the species to occur beyond the aquaculture facility, other than in an adjacent bayou. Our rotenone treatment of the facility appeared effective with only a single O. niloticus being collected six weeks after the treatment. To reduce the spread of O. niloticus in the southeastern U.S., it is important to continue to control feral populations, work to eliminate vectors for dispersal, and continue monitoring their distribution.

    The scientific literature concerning the public health response to the unprecedented hurricanes striking the Gulf Coast in August and September 2005 has focused mainly on assessing health-related needs and surveillance of injuries, infectious diseases, and other illnesses. However, the hurricanes also resulted in unintended hazardous substances releases in the affected states. Data from two states (Louisiana and Texas) participating in the Hazardous Substances Emergency Events Surveillance (HSEES) system were analyzed to describe the characteristics of hazardous substances releases in industrial settings associated with Hurricanes Katrina and Rita. HSEES is an active multi-state Web-based surveillance system maintained by the Agency for Toxic Substances and Disease Registry (ATSDR). In 2005, 166 hurricane-related hazardous substances events in industrial settings in Louisiana and Texas were reported. Most (72.3%) releases were due to emergency shut downs in preparation for the hurricanes and start-ups after the hurricanes. Emphasis is given to the contributing causal factors, hazardous substances released, and event scenarios. Recommendations are made to prevent or minimize acute releases of hazardous substances during future hurricanes, including installing backup power generation, securing equipment and piping to withstand high winds, establishing procedures to shutdown process operations safely, following established and up-to-date start-up procedures and checklists, and carefully performing pre-start-up safety reviews.

    Changes in the human migration systems of the Gulf of Mexico coastline counties affected by Hurricanes Katrina and Rita provide an example of how climate change may affect coastal populations. Crude climate change models predict a mass migration of "climate refugees," but an emerging literature on environmental migration suggests that most migration will be short-distance and short-duration within existing migration systems, with implications for the population recovery of disaster-stricken places. In this research, we derive a series of hypotheses on recovery migration predicting how the migration system of hurricane-affected coastline counties in the Gulf of Mexico was likely to have changed between the pre-disaster and the recovery periods. We test these hypotheses using data from the Internal Revenue Service on annual county-level migration flows, comparing the recovery period migration system (2007-2009) with the pre-disaster period (1999-2004). By observing county-to-county ties and flows, we find that recovery migration was strong: the migration system of the disaster-affected coastline counties became more spatially concentrated, while flows within it intensified and became more urbanized. Our analysis demonstrates how migration systems are likely to be affected by the more intense and frequent storms anticipated by climate change scenarios, with implications for the population recovery of disaster-affected places.

    To evaluate safety-net clinics' responses to a novel community-wide Patient-Centered Medical Home (PCMH) financial incentive program in post-Katrina New Orleans. Between June 2008 and June 2010, we studied 50 primary care clinics in New Orleans receiving federal funds to expand services and improve care delivery. Multiwave, longitudinal, observational study of a local safety-net primary care system. Clinic-level data from a semiannual survey of clinic leaders (89.3 percent response rate), augmented by administrative records. Overall, 62 percent of the clinics responded to financial incentives by achieving PCMH recognition from the National Committee on Quality Assurance (NCQA). Higher patient volume, higher baseline PCMH scores, and type of ownership were significant predictors of achieving NCQA recognition. The steepest increase in adoption of PCMH processes occurred among clinics achieving the highest, Level 3, NCQA recognition. Following NCQA recognition, 88.9 percent stabilized or increased their use of PCMH processes, although several specific PCMH processes had very low rates of adoption overall. Findings demonstrate that widespread PCMH implementation is possible in a safety-net environment when external financial incentives are aligned with the goal of practice innovation. © Health Research and Educational Trust.

En el suelo el agua en consecuencia se mueve hacia donde su energía decrece hasta lograr su estado de equilibrio. Se desprende entonces que la cantidad de energía potencial absoluta contenida en el agua, no es importante por sí misma, sino por su relación con la energía en diferentes lugares dentro del suelo.

    Recent evaluations of school choice school reforms have focused on improving academic achievement but have ignored associations with adolescent health and the risk of interpersonal violence. The innovative school choice model implemented in post-Katrina New Orleans provides a unique opportunity to examine these effects. Using a sample of approximately 1700 students from the 2009 School Health Connection Survey, the relationships between the type of school attended and depression, suicide planning, absences attributable to fears for personal safety, and threats of violence at school are examined. Multivariate regression analysis adjusting for self-selection into the type of school attended-a city-run high-performing school, a state-run failing school, or an independent charter school-estimates the effects of school type on student health. Relative to students at state-run schools, students who choose to attend city-run schools are less likely to plan for suicide or to miss school because they are afraid of becoming victims of violence. These beneficial effects tend to be larger for students traveling from higher violence neighborhoods. The effects for charter schools are similar but less robust. Local school jurisdictions that implement reforms allowing adolescents and their families greater freedom in school choice may also improve adolescent health. © 2014, American School Health Association.

    Hurricanes Katrina and Rita made landfall in 2005, subjecting the coastal marsh communities of Louisiana to various degrees of exposure. We collected data after the storms at 30 sites within fresh (12), brackish/intermediate (12), and saline (6) marshes to document the effects of saltwater storm surge and sedimentation on marsh community dynamics. The 30 sites were comprised of 15 pairs. Most pairs contained one site where data collection occurred historically (that is, prestorms) and one Coastwide Reference Monitoring System site. Data were collected from spring 2006 to fall 2007 on vegetative species composition, percentage of vegetation cover, aboveground and belowground biomass, and canopy reflectance, along with discrete porewater salinity, hourly surface-water salinity, and water level. Where available, historical data acquired before Hurricanes Katrina and Rita were used to compare conditions and changes in ecological trajectories before and after the hurricanes. Sites experiencing direct and indirect hurricane influences (referred to in this report as levels of influence) were also identified, and the effects of hurricane influence were tested on vegetation and porewater data. Within fresh marshes, porewater salinity was greater in directly impacted areas, and this heightened salinity was reflected in decreased aboveground and belowground biomass and increased cover of disturbance species in the directly impacted sites. At the brackish/intermediate marsh sites, vegetation variables and porewater salinity were similar in directly and indirectly impacted areas, but porewater salinity was higher than expected throughout the study. Interestingly, directly impacted saline marsh sites had lower porewater salinity than indirectly impacted sites, but aboveground biomass was greater at the directly impacted sites. Because of the variable and site-specific nature of hurricane influences, we present case studies to help define postdisturbance baseline conditions in

  9. Silver linings: a personal memoir about Hurricane Katrina and fungal volatiles

    2015-03-01

    Full Text Available In the aftermath of Hurricane Katrina, the levees protecting New Orleans, Louisiana failed. Because approximately 80% of the city was under sea level, widespread flooding ensued. As a resident of New Orleans who had evacuated before the storm, and a life-long researcher on filamentous fungi, I had known what to expect. After the hurricane I traveled home with a suitcase full of Petri dishes and sampling equipment so as to study the fungi that were eating my house. Not only were surfaces covered with fungal growth, the air itself was full of concentrated mold odor, a smell that was orders of magnitude more funky than any damp, musty basement I had ever encountered. The smell made me feel bad and I had to take regular breaks as I sampled. Being a mycotoxin expert, I knew a fair amount about sick building syndrome but believed that it was difficult to get enough respiratory exposure to toxins to cause the array of symptoms associated with the syndrome. So why was I feeling sick? Some Scandinavian experts had hypothesized that mold volatile organic compounds (VOCs might be the fungal metabolites to blame for sick building syndrome and the time in my smelly, mold infested home made me think they might be right. After securing a new job and establishing a new laboratory, I endeavored to test the hypothesis that some volatile mold metabolites might be toxic. My laboratory at Rutgers University has interrogated the role of VOCs in possible interkingdom toxicity by developing controlled microcosms for exposing simple genetic model organisms to the vapor phase of growing fungi. Both Arabidopsis thaliana and Drosophila melanogaster exhibit a range of toxic symptoms that vary with the species of fungus, the duration of exposure, and other experimental parameters. Moreover, low concentrations of chemical standards of individual fungal VOCs such as 1-octen-3-ol also exhibit varying toxicity and cause neurotoxicity in a Drosophila model.

    Nature cannot know where the poorest people in the world live, yet by a vast margin the poor outnumber the rich in the count of deceased victims in earthquakes, floods, and virtually all natural disasters with the exception of droughts that today only take lives in poor countries. Establishing just how many people die in a disaster and the circumstances of their deaths has proven to be an elusive quest. For the Katrina catastrophe we must count all those who drowned or were crushed in their homes, but should those who died taking refuge in the Superdome be included in the death toll, as well as those who died from a prior condition fatally aggravated by the stress of the disaster? In the August heat wave in New York very few people are said to have died because only those who succumbed to the medically determined condition of heat stroke were considered victims. The death toll in the very similar heat wave in Chicago in 1995 exceeded 500 because the definition of deceased victims included a broader range of causes of death. In New Orleans and Chicago the poorest among us, the oldest, and those living alone made up the overwhelmingly largest group of deceased victims. Honest counting leads to much larger figures than typical official statistics. These mortality risk factors echo the global realities of disaster vulnerability in which the poorest countries face the greatest losses of life and the greatest developmental setbacks. Regrettably, social class is the prime determinant of disaster mortality risk. Any realistic scenario of natural disaster human outcomes must take this uncomfortable reality into account.

    Ensuring continuity of care for patients with chronic illness, who are elderly or indigent presents unique challenges after disasters; this population has fewer financial resources, is less likely to evacuate, has limited access to recovery resources and is significantly dependent on charitable and government-funded institutions for care. This study expands a previous investigation of the extent to which healthcare providers in coastal Mississippi and Alabama have made changes to facilitate continued care to these populations after disasters. Key informants representing healthcare and social services organizations serving health-disparate residents of the Mississippi and Alabama Gulf Coast were interviewed regarding disaster preparation planning for the period of 2009-2012. Interview transcripts were qualitatively coded and analyzed for emerging themes using ATLAS.ti software. Participant organizations have implemented changes to ensure continuity of care for patients with chronic illness in case of disasters. Changes include patient assistance with predisaster preparation and training; evacuation planning and assistance; support to find resources in evacuation destinations; equipping patients with prescription information, diagnoses, treatment plans and advance medications when a disaster is imminent; multiple methods for patients to communicate with providers and more mandated medical needs shelters. Patients whose chronic conditions were diagnosed post-Katrina are more likely to underestimate the need to prepare. Further, patients' lack of compliance tends to increase as time passes from disasters. Although changes were implemented, results indicate that these may be inadequate to completely address patient needs. Thus, additional efforts may be needed, underscoring the complexity of adequate disaster preparation among disparate populations. Copyright © 2016 Southern Society for Clinical Investigation.

    During the Hurricane Katrina relief efforts, a new city was born overnight within the City of Houston to provide accommodation and health services for thousands of evacuees deprived of food, rest, medical attention, and sanitation. The hurricane victims had been exposed to flood water, toxic materials, physical injury, and mental stress. This scenario was an invitation for a variety of public health hazards, primarily infectious disease outbreaks. Early detection and monitoring of morbidity and mortality among evacuees due to unattended health conditions was an urgent priority and called for deployment of real-time surveillance to collect and analyze data at the scene, and to enable and guide appropriate response and planning activities. The University of Texas Health Science Center at Houston (UTHSC) and the Houston Department of Health and Human Services (HDHHS) deployed an ad hoc surveillance system overnight by leveraging Internet-based technologies and Services Oriented Architecture (SOA). The system was post-coordinated through the orchestration of Web Services such as information integration, natural language processing, syndromic case finding, and online analytical processing (OLAP). Here we will report the use of Internet-based and distributed architectures in providing timely, novel, and customizable solutions on demand for unprecedented events such as natural disasters.

    Prior to Hurricanes Katrina and Rita (HKR), significant associations were noted between soil lead (SL) and blood lead (BL) in New Orleans. Engineering failure of New Orleans levees and canal walls after HKR set the stage for a quasi-experiment to evaluate BL responses by 13 306 children to reductions in SL. High density soil surveying conducted in 46 census tracts before HKR was repeated after the flood. Paired t test results show that SL decreased from 328.54 to 203.33 mg/kg post-HKR (t = 3.296, p or =50% decrease in SL. Also individual BL in children was predicted as a function of SL, adjusting for age, year of observation, and depth of flood waters. At the individual scale, BL decreased significantly in post-HKR as a function of SL, with BL decreases ranging from b = -1.20 to -1.65 microg/dL, depending on the decline of SL and whether children were born in the post-HKR period. Our results support policy to improve soil conditions for children.

    The present analyses examined the differential risks of and protective factors against depressive symptoms of African American and Non-Hispanic White American student volunteers, respectively after Hurricanes Katrina and Rita (H-KR). A total sample of 554 student volunteers were recruited from mental health professional programs at five universities located in the Deep South, namely areas severely impacted by H-KR during fall semester 2005. The response rate was 91% (n = 505). African American respondents (n = 299) and Non-Hispanic White Americans (n = 206) completed the survey questionnaires. Respondents retrospectively provided information on peritraumatic emotional reactions and previous trauma that were recalled by H-KR and H-KR stressors. African American respondents reported higher levels of depressive symptoms (65.2%) than their Non-Hispanic White counterparts (34.8%). Hierarchical regression analyses revealed that disaster related stressors affected African Americans (p < 0.001), but not Non-Hispanic Whites. However, African Americans who experienced peritraumatic positive emotions had lower depression levels. Lower rates of recollection of prior traumas during H-KR were reported by African American respondents, whereas previous trauma recollections predicted symptoms among Non-Hispanic White Americans (p < 0.05). Exhibiting more optimism had lower depression levels among Non-Hispanic White Americans. Peritraumatic negative emotion was the only shared risk for depressive symptoms of both groups. Findings underscore racially different levels of depressive symptoms that may contribute to varying degrees of resilience among student volunteers. Future research and practice may address these racial differences by understanding the risk factors for depressive symptoms to develop appropriate interventions for racial groups, and cultivating the protective factors that contribute to resilience from traumatic experiences.

    The relationship between mental health status and smoking is complicated and often confounded by bi-directionality, yet most research on this relationship assumes exogeneity. The goal of this article is to implement an instrumental variable approach to (1) test the exogeneity assumption and (2) report on the association between mental health status and smoking post-disaster. This analysis utilizes the 2006 and 2007 Louisiana Behavioral Risk Factor Surveillance Survey to examine the link between mental distress and smoking in areas affected by Hurricanes Katrina and Rita. Residence in a hurricane-affected parish (county) was used as an instrumental variable for mental distress. Just over 22% of the sample resided in a hurricane-affected parish. Residents of hurricane-affected parishes were significantly more likely to report occasional and frequent mental distress. Residence in a hurricane-affected parish was not significantly associated with smoking status. With residence established as a salient instrumental variable for mental distress, the exogeneity assumption was tested and confirmed in this sample. A dose-response relationship existed between mental distress and smoking, with smoking prevalence increasing directly (and non-linearly) with mental distress. In this sample, the relationship between mental distress and smoking status was exogenous and followed a dose-response relationship, suggesting that the disasters did not result in an uptake of smoking initiation, but that the higher amounts of mental distress may lead to increased use among smokers. The findings suggest that tobacco control programs should devise unique strategies to address mentally distressed populations.

  13. Kinematic structure of convective-scale elements in the rainbands of Hurricanes Katrina and Rita (2005)

    Hence, Deanna A.; Houze, Robert A.

    2008-08-01

    Airborne Doppler radar data collected during the Hurricane Rainband and Intensity Change Experiment (RAINEX) show the convective-scale air motions embedded in the principal rainbands of hurricanes Katrina and Rita. These embedded convective cells have overturning updrafts and low-level downdrafts (originating at 2-4 km) that enter the rainband on its radially outward side and cross over each other within the rainband as well as a strong downdraft emanating from upper levels (6+ km) on the radially inward side. These vertical motion structures repeat from one convective cell to another along each rainband. The resulting net vertical mass transport is upward in the upwind portion of the band and greatest in the middle sector of the principal rainband, where the updraft motions contribute generally to an increase of potential vorticity below the 3-4 km level. Because the convective cells in the middle sector are systematically located radially just inside the secondary horizontal wind maximum (SHWM), the local increase in vorticity implied by the convective mass transport is manifest locally as an increase in the strength of the SHWM at midlevels (˜4 km). The overturning updrafts of the convective cells tilt, stretch, and vertically transport vorticity such that the convergence of the vertical flux of vorticity strengthens the vorticity anomaly associated with the SHWM. This process could strengthen the SHWM by several meters per second per hour, and may explain how high wave number convective-scale features can influence a low wave number feature such as the principal rainband, and subsequently influence the primary vortex.

    Concerns about mental health recovery persist after the 2005 Gulf storms. We propose a recovery model and estimate costs and outcomes. To estimate the costs and outcomes of enhanced mental health response to large-scale disasters using the 2005 Gulf storms as a case study. Decision analysis using state-transition Markov models for 6-month periods from 7 to 30 months after disasters. Simulated movements between health states were based on probabilities drawn from the clinical literature and expert input. A total of 117 counties/parishes across Louisiana, Mississippi, Alabama, and Texas that the Federal Emergency Management Agency designated as eligible for individual relief following hurricanes Katrina and Rita. Hypothetical cohort, based on the size and characteristics of the population affected by the Gulf storms. Intervention Enhanced mental health care consisting of evidence-based screening, assessment, treatment, and care coordination. Morbidity in 6-month episodes of mild/moderate or severe mental health problems through 30 months after the disasters; units of service (eg, office visits, prescriptions, hospital nights); intervention costs; and use of human resources. Full implementation would cost $1133 per capita, or more than $12.5 billion for the affected population, and yield 94.8% to 96.1% recovered by 30 months, but exceed available provider capacity. Partial implementation would lower costs and recovery proportionately. Evidence-based mental health response is feasible, but requires targeted resources, increased provider capacity, and advanced planning.

  16. Silver linings: a personal memoir about Hurricane Katrina and fungal volatiles.

    2015-01-01

    In the aftermath of Hurricane Katrina, the levees protecting New Orleans, Louisiana failed. Because approximately 80% of the city was under sea level, widespread flooding ensued. As a resident of New Orleans who had evacuated before the storm and a life-long researcher on filamentous fungi, I had known what to expect. After the hurricane I traveled home with a suitcase full of Petri dishes and sampling equipment so as to study the fungi that were "eating my house." Not only were surfaces covered with fungal growth, the air itself was full of concentrated mold odor, a smell that was orders of magnitude more funky than any damp, musty basement I had ever encountered. The smell made me feel bad and I had to take regular breaks as I sampled. Being a mycotoxin expert, I knew a fair amount about "sick building syndrome" but believed that it was difficult to get enough respiratory exposure to toxins to cause the array of symptoms associated with the syndrome. So why was I feeling sick? Some Scandinavian experts had hypothesized that mold volatile organic compounds (VOCs) might be the fungal metabolites to blame for sick building syndrome and the time in my smelly, mold infested home made me think they might be right. After securing a new job and establishing a new laboratory, I endeavored to test the hypothesis that some volatile mold metabolites might be toxic. My laboratory at Rutgers University has interrogated the role of VOCs in possible interkingdom toxicity by developing controlled microcosms for exposing simple genetic model organisms to the vapor phase of growing fungi. Both Arabidopsis thaliana and Drosophila melanogaster exhibit a range of toxic symptoms that vary with the species of fungus, the duration of exposure, and other experimental parameters. Moreover, low concentrations of chemical standards of individual fungal VOCs such as 1-octen-3-ol also exhibit varying toxicity and cause neurotoxicity in a Drosophila model. Collectively, these data suggest that

    In the aftermath of large-scale disasters, the public's dependency on federal and state agencies for information about public safety and environmental risk is acute. While formal rules and procedures are in place to guide policy decisions in environmental risk assessment of spatially concentrated hazards such as regulated waste sites or vacant city lots, standard procedures for risk assessment seem potentially less well-suited for urban-scale disaster zones where environmental hazards may be widely dispersed and widely varying. In this paper we offer a new approach for the social assessment of regulatory science in response to large-scale disaster, illustrating our methodology through a socio-spatial analysis of the U.S. Environmental Protection Agency's (EPA) hazard assessment in New Orleans, Louisiana, following Hurricane Katrina in 2005. We find that the agency's commitment of epistemic resources or 'knowledge investments' varied considerably across the flood-impacted portion of the city, concentrating in poorer and disproportionately African American neighborhoods previously known to be heavily contaminated. We address some of the study's social and policy implications, noting the multidimensionality and interactive nature of knowledge investments and the prospects for deepening and extending this approach through comparative research

No obstante, la necesidad obligaba, y cuando los recursos u hombres de una casa escaseaban, la mujer tenía que salir a buscarse el sustento. Este es el caso de cientos de mujeres del Principado de Asturias, dónde, a mediados del siglo XVIII, la realidad femenina difería de lo que lo que se consideraba ideal. Este trabajo arrojará pues luz, en un campo hasta ahora desconocido: el del mundo profesional de las mujeres asturianas del Setecientos, dónde comprobaremos cómo en ocasiones llegaban a adquirir, gracias a su status profesional, papeles relevantes dentro de la sociedad.

    Full Text Available El complejo suspensorio del hombro es una estructura sumamente importante, compuesta por un anillo de huesos y tejidos blandos. Las lesiones aisladas de este complejo anatómico son frecuentes y no afectan su estabilidad. La interrupción doble conduce a la inestabilidad de esta estructura y usualmente requiere tratamiento quirúrgico. La triple interrupción, por su parte, es sumamente rara y es encontrada en casos de trauma de alta energía a menudo en asociación con otras lesiones. Se presenta una triple lesión del complejo suspensorio del hombro en un paciente de 46 años de edad, con una fractura de la glenoides, del acromion tipo III de Kuhn y de la coracoides tipo II de Ogawa. En este caso, la fractura del acromion fue tratada con fijación percutánea con alambres de Kirschner, por tener asociado lesiones de partes blandas que contraindicaron la reducción abierta. La fractura de la glenoides y de la apófisis coracoides fueron tratadas conservadoramente. Después de 6 meses de evolución, el paciente tuvo un resultado funcional aceptable, con una abducción de 90 grados, los 30 grados de rotación externa y 70 de rotación interna, además asintomático y consolidación de todas las fracturas. A pesar de ser catalogada de una lesión grave del cinturón escapular y estar asociada a otras lesiones se obtuvo un resultado satisfactorio al final del tratamiento.

    Full Text Available Este artículo ofrece una síntesis del estado del arte sobre los temas del desarrollo y es parte integrante de la investigación sobre los pymes y el desarrollo económico. Desde los enfoques clásicos hasta los modelos contemporáneos se ha debatido ampliamente la relación entre crecimiento y desarrollo económico. Para muchos autores el desarrollo está vinculado a los problemas de distribución. Para otros el desarrollo es sinónimo de disminución y eliminación de la pobreza o se resuelve a través de aumentar la producción. Otros enfoques se centran en la importancia de minimizar los costos de transacción o en la generación de una mejor calidad de vida. Ahora bien, las teorías del desarrollo predominantes hasta la década de los ochenta, asumen que el proceso del desarrollo no es más que la ruta de homogenización de los mercados duales. Para otros autores el problema se explica por la diferencia de tecnologías, capital social, capital intelectual y humano. Esta síntesis revisa entre otros enfoques los modelos con los que se ha intentado explicar la peculiaridad del desarrollo en los países del tercer mundo, en las economías en proceso de industrialización y la complejidad del caso particular del desarrollo en Latinoamérica y su modelo de sustitución de importaciones.

    Full Text Available El salario y la jornada de trabajo han sido en nuestro país, seguramente, los dos temas que forjaron el nacimiento del Derecho del trabajo1. Dentro del primero, el método de fijación del salario predominante, generalmente, refleja algo mucho más amplio que la política salarial de un gobierno. En realidad pone de manifiesto un eje central de la política laboral, o, más aún, una determinada forma de abordar la cuestión social.Por ese motivo nos proponemos analizar el tema a partir de su evolución histórica y de algunos de los particularismos que, en la concepción de Barbagelata, posee el Derecho del trabajo: la subyacencia del conflicto en las relaciones laborales y la significación del tiempo social.En esa perspectiva se confirma, según enseña Ermida Uriarte, el indudable papel protagónico que han desempeñado los Consejos de Salarios en el Derecho del trabajo y el sistema laboral uruguayo.Presentación.

    Lewis, Mark David; Spruce, Joseph; Evans, David; Anderson, Daniel

    2012-01-01

    Hurricane damage to forests can be severe, causing millions of dollars of timber damage and loss. To help mitigate loss, state agencies require information on location, intensity, and extent of damaged forests. NASA's MODerate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) time series data products offers a potential means for state agencies to monitor hurricane-induced forest damage and recovery across a broad region. In response, a project was conducted to produce and assess 250 meter forest disturbance and recovery maps for areas in southern Mississippi impacted by Hurricane Katrina. The products and capabilities from the project were compiled to aid work of the Mississippi Institute for Forest Inventory (MIFI). A series of NDVI change detection products were computed to assess hurricane induced damage and recovery. Hurricane-induced forest damage maps were derived by computing percent change between MODIS MOD13 16-day composited NDVI pre-hurricane "baseline" products (2003 and 2004) and post-hurricane NDVI products (2005). Recovery products were then computed in which post storm 2006, 2007, 2008 and 2009 NDVI data was each singularly compared to the historical baseline NDVI. All percent NDVI change considered the 16-day composite period of August 29 to September 13 for each year in the study. This provided percent change in the maximum NDVI for the 2 week period just after the hurricane event and for each subsequent anniversary through 2009, resulting in forest disturbance products for 2005 and recovery products for the following 4 years. These disturbance and recovery products were produced for the Mississippi Institute for Forest Inventory's (MIFI) Southeast Inventory District and also for the entire hurricane impact zone. MIFI forest inventory products were used as ground truth information for the project. Each NDVI percent change product was classified into 6 categories of forest disturbance intensity. Stand age

  10. Regeneration of coastal marsh vegetation impacted by hurricanes Katrina and Rita

    Science.gov (United States)

    Middleton, B.A.

    2009-01-01

    The dynamics of plant regeneration via seed and vegetative spread in coastal wetlands dictate the nature of community reassembly that takes place after hurricanes or sea level rise. The objectives of my project were to evaluate the potential effects of saltwater intrusion and flooding of Hurricanes Katrina and Rita on seedling regeneration in coastal wetlands of the Gulf Coast. Specifically I tested hypotheses to determine for species in fresh, brackish and salt marshes of the Gulf Coast if 1) the pattern of seed germination and seedling recruitment differed with distance from the shoreline, and 2) seed germination and seedling recruitment for various species were reduced in higher levels of water depth and salinity. Regarding Hypothesis 1, seedling densities increased with distance from the shoreline in fresh and brackish water marshes while decreasing with distance from the shoreline in salt marshes. Also to test Hypothesis 1, I used a greenhouse seed bank assay to examine seed germination from seed banks collected at distances from the shoreline in response to various water depths and salinity levels using a nested factorial design. For all marsh types, the influence of water level and salinity on seed germination shifted with distance from the shoreline (i.e., three way interaction of the main effects of distance nested within site, water depth, and salinity). Data from the seed bank assay were also used to test Hypothesis 2. The regeneration of species from fresh, brackish, and salt marshes were reduced in conditions of high salinity and/or water, so that following hurricanes or sea level rise, seedling regeneration could be reduced. Among the species of these coastal marshes, there was some flexibility of response, so that at least some species were able to germinate in either high or low salinity. Salt marshes had a few fresher marsh species in the seed bank that would not germinate without a period of fresh water input (e.g., Sagittaria lancifolia) as well

  12. Effect of Hurricane Katrina on Low Birth Weight and Preterm Deliveries in African American Women in Louisiana, Mississippi, and Alabama

    Directory of Open Access Journals (Sweden)

    Chau-Kuang Chen

    2012-04-01

    Full Text Available Using three modeling techniques (GLR, GEP, and GM, the effect of Hurricane Katrina on low birth weight and preterm delivery babies for African American women is examined in Louisiana, Mississippi and Alabama. The study results indicate that risk factors associated with low birth weight and preterm delivery for American African women include unemployment and percent of mothers between the ages of 15-19. Among White women, ages 15-19, risk factors included poverty rate, median household income, and total birth rate. The GMs performed accurate predictions with increasing low birth weight and preterm delivery trends for African American women in the Gulf Coast states and other U.S. states, and decreasing low birth weight and preterm delivery trends for their White counterparts in the same state locations. Data presented between 2007-2010 show low birth weight and preterm delivery for White women as a decreasing tendency while adverse birth outcomes for African American women exhibited a monotonically increasing trend. The empirical findings suggest that health disparities will continue to exist in the foreseeable future, if no effective intervention is taken. The models identify risk factors that contribute to adverse birth outcomes and offer some insight into strategies and programs to address and ameliorate these effects.

    2011-01-01

    Full Text Available La Ley del suelo del País Vasco del 2007 nace con el objeto de favorecer el acceso a una vivienda digna. Sin embargo, en la medida en que apuesta por frenar la especulación y la sostenibilidad del medio legisla sobre el tratamiento que se le ha de aportar al suelo no urbanizable. En este caso, no altera sustancialmente la regulación del suelo rural pero sí incorpora nuevas obligaciones dirigidas a frenar la intensidad de la urbanización en este suelo. Se regula la construcción de nueva vivienda, el desarrollo urbanístico de núcleos y barrios rurales y se obliga a profundizar en la calificación del suelo no urbanizable. La aplicación de los nuevos contenidos quedan en manos de los municipios e instituciones sectoriales y los primeros resultados parecen denotar un cambio de tendencia en municipios que han observado la pérdida de calidad paisajística del medio rural, la creciente especulación y la desagrarización de este entorno.

    Full Text Available El color es un atributo importante en la elección del producto dulce de leche por parte del consumidor. El mismo se desarrolla en el proceso de elaboración debido principalmente a las reacciones de pardeamiento no enzimático, las cuales se ven influenciadas por varios factores. En este trabajo se evaluó el desarrollo de color, con el tiempo de tratamiento térmico y el pH inicial como variables tecnológicas, en un sistema modelo compuesto de caseinato, lactosa, sacarosa y agua destilada cuya composición fue similar a la del dulce de leche comercial. El estudio del color se realizó utilizando los parámetros de medición de color del sistema CIELAB y el índice de Kubelka Munk (K/S. Con ambos métodos se constató un aumento significativo del dE*ab y del K/S con el tiempo de tratamiento térmico y el pH inicial. Con el sistema CIELAB además se observó una tendencia a disminuir la luminosidad con el tiempo y el aumento del pH inicial, y el aumento de a* con el tiempo.

    Full Text Available Nei primi anni ’50 Franco Modigliani, insieme a Richard Brumberg e ad Albert Ando, formulò lateoria del ciclo vitale del consumo e del risparmio, che ha riscosso un enorme e indiscussosuccesso per almeno tre decenni. Tuttavia, a partire dai primi anni ’80 la teoria del ciclo vitale èstata criticata in modo sempre più serrato, per almeno quattro ragioni. La prima consistenell’esistenza di una significativa trasmissione intergenerazionale della ricchezza, da ricondurre acause esogene al modello del ciclo vitale. La seconda ragione è rappresentata dalla crescenteevidenza che i ricchi continuano a risparmiare in misura maggiore rispetto ai meno fortunati,come, in effetti, Keynes sosteneva. Il terzo motivo è che vi sono prove sempre più evidenti,almeno nell’Europa occidentale e in Giappone, che le famiglie giovani, durante i venti e i trentaanni di età, risparmiano una quota positiva e crescente del proprio reddito, e ciò si pone indeciso contrasto con la versione originaria della teoria del ciclo vitale. Infine, numerosi lavoriempirici hanno rilevato che i pensionati accantonano una parte elevata del proprio reddito. Ciòimpone un serio ripensamento dell’approccio della teoria del ciclo vitale, che interessa sia l’analisieconomica sia la politica economica.

    RESUMEN:En este trabajo informamos la detecci6n de 20 erupciones en la li'nea de =18cm (1667MHz) del radical OH en el Cometa Halley.Las observaciones incluyen todos los monitoreos existentes y se extienden desde 120 dias antes del perihelio hasta 90 dias despues.Se detectan bruscos crecimientos en el flujo medido,hasta un factor 1O,seguidos por decaimientos lentos asociados con la fotodisociaci6n del OH. Se obtuvieron valores para el tiempo de vida fotoquimico del OH y del H2O basandose en el modelo desarrollado previamente por Silva(1988). Esos tiempos de vida estan de acuerdo con predicciones teoricas y con las observaciones en el Ultravioleta, y los resultados, los que son fuertemente dependientes de la velocidad heliocentrica del Coineta (variando hasta un factor 6), han sido calculados para varios rangos de velocidad entre +28 y -28 km/seg.

    Full Text Available El presente artículo es un estudio de los componentes del sistema electoral, diseñado por el legislador mexicano para integrar al parlamento federal. Estudio desarrollado a sabiendas de la importancia que reviste el sistema electoral como un medio que permite a los ciudadanos convertir su voto expresado en las urnas en escaños a favor de determinado candidato o partido. En dicho análisis tomamos en cuenta la evolución constitucional del sistema electoral mexicano, la participación de las fuerzas minoritarias en la integración del Senado y de la Cámara de Diputados, la división que se hace del territorio en circunscripciones electorales, la barrera electoral que se fija a los partidos políticos para acceder a la representación en el Parlamento, la fórmula de asignación que se aplica a la votación obtenida, para finalmente concluir que el sistema electoral mexicano es esencialmente mayoritario aun cuando se vista de proporcional.

    Full Text Available Se comparan las tradiciones críticas y analíticas a través de un análisis del concepto de Habermas sobre el "universal pragmático" (Comunicación y la evolución de la sociedad y la noción de Talcott Parson del "paradigma de la condición humana" (Teoría de la Acción y la condición humana. Habermas y Parsons insisten fuertemente en el elemento simbólico del lenguaje en la sociedad, tendente al misterio y el reencantamiento de las categorías epistemológicas fundamentales. Sus posiciones deben su identidad y sentido del futuro a la sociedad industrial avanzada. La recuperación por parte de Habermas del diálogo entre las esferas teórica ("universal pragmático" e histórica ("paradigma reconstructivo", rompiendo con las posiciones del marxismo y los creadores de la Escuela de Frankfurt, abren un camino esperanzador para la investigación. Se analiza el normativismo epistemológico oculto del "paradigma de la condición humana" de Parson a través de sus primeros trabajos. El conflicto entre las tradiciones analítica y crítica se atribuye a diferentes grados de énfasis normativo-subjetivos y generativo-intersubjetivos.

    Full Text Available Este estudio analizó los factores psicosociales que explicaban el presentismo o deterioro laboral autopercibido asociado a trabajar enfermo. La muestra fue de 676 trabajadores del sistema de salud chileno (84% de mujeres, M = 35.9 anos, en su mayoría enfermeras y técnicos paramédicos. Se aplicó un cuestiona- ˜ rio sociodemográfico, el Job Content Questionnaire, el Effort-Reward Imbalance, el Health Performance Questionnaire y una escala de interferencia del trabajo en la vida familiar. La regresión lineal explicó el 21% de la varianza del deterioro laboral percibido. Este último se asoció a asistir a trabajar enfermo. Los resultados sugieren que el deterioro del desempeno y asistir a trabajar enfermo son dos aspectos del ˜ mismo proceso. El ausentismo por razones de salud, la interferencia del trabajo en la vida familiar y la sintomatología emocional predijeron el deterioro laboral. Éste último se asoció negativamente a trabajar en turnos, controlando edad y salario. Los resultados sugieren que el presentismo es explicado por factores del contexto de trabajo y el conflicto trabajo-familia.

    Bergan, Timothy; Thomas, Dana; Schwartz, Erica; McKibben, Jodi; Rusiecki, Jennifer

    2015-12-01

    Disaster responders are increasingly called upon to assist in various natural and manmade disasters. A critical safety concern for this population is sleep deprivation; however, there are limited published data regarding sleep deprivation and disaster responder safety. We expanded upon a cross-sectional study of 2695 United States Coast Guard personnel who responded to Hurricanes Katrina and Rita. Data were collected via survey on self-reported timing and location of deployment, missions performed, health effects, medical treatment sought, average nightly sleep, and other lifestyle variables. We created a 4-level sleep deprivation metric based on both average nightly reported sleep (d5hours; >5hours) and length of deployment (d2weeks; >2weeks) to examine the association between sustained sleep deprivation and illnesses, injuries, and symptoms using logistic regression to calculate odds ratios (ORs) and 95% confidence intervals. The strongest, statistically significant positive ORs for the highest sleep deprivation category compared with the least sleep-deprived category were for mental health and neurologic effects, specifically depression (OR=6.76), difficulty concentrating (OR=8.33), and confusion (OR=11.34), and for dehydration (OR=9.0). Injuries most strongly associated with sleep deprivation were twists, sprains, and strains (OR=6.20). Most health outcomes evaluated had monotonically increasing ORs with increasing sleep deprivation, and P tests for trend were statistically significant. Agencies deploying disaster responders should understand the risks incurred to their personnel by sustained sleep deprivation. Improved planning of response efforts to disasters can reduce the potential for sleep deprivation and lead to decreased morbidity in disaster responders. Published by Elsevier Inc.

    Full Text Available Actualmente en la zona conurbana sur de la ciudad de Tuxtla Gutiérrez se manifiestan movimientos geológicos en donde la urbanización promueve su propia vulnerabilidad principalmente ante lluvias intensas provocadas por fenómenos hidrometeorológicos como tormentas tropicales y huracanes, e incluso de lluvias ordinarias, impactando además a otras partes bajas de la ciudad. Este trabajo determina zonas potencialmente activas e inactivas y su vulnerabilidad física en cuatro cuencas a escala 1:20 000, lo que permite integrar criterios que identifican localmente a los procesos evolutivos de movimientos de masas en laderas, determinando escenarios temporales de actividad peligrosa. Para la obtención de elementos categóricos, los resultados muestran los peligros diferenciados en geológicos y los que tendrán su máximo desarrollo en lluvias extraordinarias; de los cuales se deriva a la determinación de sitios para la conservación, rehabilitación y con menor restricción de uso urbano.

    2005-01-01

    Full Text Available Desde el punto de vista farmacológico, es importante comprender qué es el alcohol y cómo actúa en el organismo. No existe una causa simple, sino una interacción complicada de factores neuroquímicos, fisiológicos, psicológicos y sociales que originan y desarrollan esta grave enfermedad fármaco-dependiente. La acción psicofisiológica y farmacodinámica del alcohol es fundamentalmente depresiva, por la reducción de la transmisión sináptica en el sistema nervioso humano. Es un hecho conocido que el consumo excesivo de alcohol causa una disfunción aguda y crónica del cerebro, produciendo trastornos en el sistema nervioso central, presentando alteraciones en la memoria y en las funciones intelectuales como cálculo, comprensión y aprendizaje. A nivel hepático tiene lugar, en su mayoría, el metabolismo del alcohol, produciéndose un hígado graso alcohólico, aumentando el tamaño, terminando en necrosis e inflamación grave del hígado; esto se llama hepatitis alcohólica, y si se sigue consumiendo alcohol se desarrollará la cirrosis. El alcohol también ha estado relacionado con alteraciones del miocardio; se ha constatado en animales de experimentación sanos que tanto la velocidad de contracción del músculo cardiaco y su máxima tensión disminuyen en presencia del alcohol, como consecuencia, la fuerza de cada contracción y el aumento de presión en el ventrículo izquierdo son menores, perdiendo eficacia el corazón como bomba.

    Full Text Available En vista de la importancia del equilibrio económico del contrato dentro del marco de la contratación pública, el presente artículo pretende demostrar la procedencia de su aplicación a los contratos estatales sometidos al régimen del derecho privado. Mediante la reflexión y el estudio de la jurisprudencia sobre el tema se presentarán los principales motivos expuestos por las providencias que apoyan la tesis planteada. Se exponen así los temas del interés colectivo y los preceptos constitucionales como bases de este principio del equilibrio económico.

    2006-10-01

    Full Text Available Abstract Background Geographic Information Systems (GIS can provide valuable insight into patterns of human activity. Online spatial display applications, such as Google Earth, can democratise this information by disseminating it to the general public. Although this is a generally positive advance for society, there is a legitimate concern involving the disclosure of confidential information through spatial display. Although guidelines exist for aggregated data, little has been written concerning the display of point level information. The concern is that a map containing points representing cases of cancer or an infectious disease, could be re-engineered back to identify an actual residence. This risk is investigated using point mortality locations from Hurricane Katrina re-engineered from a map published in the Baton Rouge Advocate newspaper, and a field team validating these residences using search and rescue building markings. Results We show that the residence of an individual, visualized as a generalized point covering approximately one and half city blocks on a map, can be re-engineered back to identify the actual house location, or at least a close neighbour, even if the map contains little spatial reference information. The degree of re-engineering success is also shown to depend on the urban characteristic of the neighborhood. Conclusion The results in this paper suggest a need to re-evaluate current guidelines for the display of point (address level data. Examples of other point maps displaying health data extracted from the academic literature are presented where a similar re-engineering approach might cause concern with respect to violating confidentiality. More research is also needed into the role urban structure plays in the accuracy of re-engineering. We suggest that health and spatial scientists should be proactive and suggest a series of point level spatial confidentiality guidelines before governmental decisions are made

    Full Text Available Este artículo muestra evidencia lingüístico-discursiva del intento del Presidente Piñera por acallar las influencias sociales del movimiento estudiantil chileno del año 2011. Desde una mirada crítica se da cuenta del comportamiento discursivo de este hablante en el marco del primer conflicto social que enfrentó el nuevo gobierno de derecha en Chile. El valor teórico-metodológico de este estudio radica en la mirada triangular a las intervenciones discursivas. A través del análisis de un corpus de cuatro intervenciones presidenciales desde las perspectivas de las funciones estratégicas del discurso político, la teoría de la valoración y la lingüística de corpus se observa cómo Piñera deslegitima al movimiento social asociando las demandas referidas a educación con la violencia y el desorden público generado en el contexto de las crecientes marchas a lo largo del país.

    Full Text Available Motozintla es una ciudad de alto riesgo histórico de desastres de origen hidrometeorológico como lluvias torrenciales y huracanes. Se han registrado grandes pérdidas materiales y de proyectos de vida en la población. El objetivo de este estudio es conocer las percepciones sobre la salud y desastres que son albergadas por estudiantes que viven en este municipio del estado de Chiapas, México. Métodos: Se aplicaron 378 cuestionarios que contenían preguntas cerradas y abiertas a estudiantes del Centro de Bachillerato Tecnológico Industrial y de Servicios No. 243 y de la Universidad de Ciencias y Artes de Chiapas. Las preguntas se centraron en la salud y su relación con los desastres. Resultados: muestran que el 45.5% del estudiantado consultado percibió la salud en una manera integral, como un estado de bienestar en los aspectos físico, psicológico o social; el 26.7% la percibió como la ausencia de enfermedad, dolor o molestias. El 26.2% mencionó diversos aspectos del bienestar individual relacionado con la alimentación, el sentirse bien o mal y otras satisfacciones de la vida. Con relación al contexto de los desastres, el 36.8% percibió el desastre como la presencia de los fenómenos naturales; un 29.4%, como un suceso que provoca destrucción y muerte. El 17.2% restante mencionó el desastre como algún problema físico o social, como algo imprevisto o como un peligro. Conclusión: La mayoría de los estudiantes percibió la salud como el bienestar físico, psicológico y social. Los desastres los encuentran relacionados con los fenómenos naturales y, en general, subestiman el riesgo; la salud no es dependiente ni relacionada con los desastres.

    La Oficina del Estudio Geologico de los Estados Unidos (U.S. Geological Survey, 0 USGS) ha monitoreado la calidad del agua de la cuenca del Rio Grande (Rio Bravo del Norte) desde 1995 como parte de la rediseiiada Red Nacional para Contabilizar la Calidad del Agua de los Rios (National Stream Quality Accounting Network, o NASOAN) (Hooper and others, 1997). EI programa NASOAN fue diseiiado para caracterizar las concentraciones y el transporte de sedimento y constituyentes quimicos seleccionados, encontrados en los grandes rios de los Estados Unidos - incluyendo el Misisipi, el Colorado y el Columbia, ademas del Rio Grande. En estas cuatro cuencas, el USGS opera actualmente (1998) una red de 40 puntos de muestreo pertenecientes a NASOAN, con un enfasis en cuantificar el flujo en masa (la cantidad de material que pasa por la estacion, expresado en toneladas por dial para cada constituyente. Aplicacando un enfoque consistente, basado en la cuantificacion de flujos en la cuenca del Rio Grande, el programa NASOAN esta generando la informacion necesaria para identificar fuentes regionales de diversos contaminantes, incluyendo sustancias qui micas agricolas y trazas elementos en la cuenca. EI efecto de las grandes reservas en el Rio Grande se puede observar segun los flujos de constituyentes discurren a 10 largo del rio. EI analisis de los flujos de constituyentes a escala de la cuenca proveera los medios para evaluar la influencia de la actividad humana sobre las condiciones de calidad del agua del Rio Grande.

    Full Text Available La luxación del codo, asociada a la fractura del proceso coronoideo y a la fractura de la cabeza radial, es denominada “tríada terrible del codo”, debido a la complejidad al abordar el tratamiento correcto y lo desalentador de los resultados que se obtienen con el mismo. Se realizó un estudio prospectivo, donde se recogen los resultados postoperatorios, obtenidos en cuatro pacientes con inestabilidad traumática aguda del codo, tratados entre enero de 2012 y mayo de 2013, que acudieron inicialmente al cuerpo de guardia del Hospital General Docente “Dr. Ernesto Guevara de La Serna” y tuvieron un seguimiento medio de ocho meses. El proceder consistió en reparación de la coronoides, del ligamento lateral externo, reparación de la cúpula radial, cupulectomía y colocación de pin endomedular; la técnica operatoria a emplear se definió por los estudios radiográficos realizados y los hallazgos en el transcurso del proceder. Los pacientes, tres hombres y una mujer, tuvieron cinco codos lesionados y un promedio de edad de 34 años. Como resultado del tratamiento la flexión fue normal entre 130-135° en 4 codos y limitada en uno a 110°, la extensión se encontró limitada de 8 a 21° en todos los pacientes, la pronosupinación se mantuvo limitada en todos los casos entre 5 y 22°. La intervención quirúrgica mediante fijación y reparación de los estabilizadores del codo proporcionó a corto plazo una funcionabilidad del codo cercana a la normalidad, los pacientes evolucionaron positivamente. Las complicaciones fueron: reluxación, infección local y aflojamiento de la osteosíntesis

    Full Text Available La gerencia de este siglo debe estar plenamente identificada con la administración para planear, organizar, decidir y obtener resultados definidos, evaluados y alcanzados a través de las personas. Para poder gerenciar el cuidado se debe saber administrar. El objetivo de enfermería es cuidar; el objetivo de la gerencia es la conducción de la producción de bienes o servicios en las organizaciones. La gerencia del cuidado implica: motivación, creatividad, responsabilidad y ética por parte del cuidador y de quien cuida, claridad de actitud frente al ser y al qué hacer por parte del cuidador. Se puede concluir que la gerencia (administración, el cuidado (producto de calidad, el servicio (valor intangible, querer servir son un trinomio que deben ir de la mano de manera integrada para el logro de los objetivos propuestos por la organización de salud y de enfermería.

    Purpose Although disaster exposure is linked with increased child aggression, population-level trends are unknown. Pre- to post-Katrina changes in violence-related behaviors among New Orleans high school youth (ages 12-18) were assessed. Methods Data from the 2003 (pre-Katrina), 2005 (pre-Katrina) and 2007 (post-Katrina) New Orleans Youth Risk Behavior Survey (n=5,267) were utilized. Crude comparisons across years of population characteristics and violence behavior prevalence were made with chi-square analyses. Changes in violence-related behaviors over time were assessed with logistic regression models including indicators for survey years and controls for compositional changes. Results Age, gender and race/ethnicity of school-attending youth were stable across years. In models controlling for demographics, most behaviors were stable over time. Some changes were observed for all groups: dating violence and forced sex increased prior to the storm; weapon carrying and missing school due to feeling unsafe decreased after the storm. Among African American adolescents only, being threatened at school increased before Katrina. Conclusions Results do not support significant population-level increases in violent behavior among New Orleans school-attending youths post-Katrina. Factors that buffered New Orleans students from post-Katrina violence increases, such as population composition changes or increased supportive services, may explain these findings. PMID:21783056

    Full Text Available Esta investigación tiene un diseño cualitativo descriptivo, transversal para comprender las diferencias existentes en los conocimientos, actitudes y prácticas influidas por la percepción o sentido cultural de cuidar del cuidador primario, como elemento básico para caracterizar elementos culturales presentes en el ambiente de cuidado al enfermo o discapacitado que está en casa a través de la indagación profunda de la percepción y sentimientos que tiene tanto el cuidador primario como el ser cuidado en casa. Se realizó con los usuarios inscritos del Programa de Promoción y Prevención de la indagación profunda de la percepción y sentimientos Universidad Popular del Cesar (IPS-UPC de los enfermos crónicos y discapacitados a nivel comunitario del grupo extramural de la comuna cinco y del Hospital Eduardo Arredondo Daza de la ciudad de Valledupar, Colombia. El valor de realizar este proyecto, está en desocultar los múltiples significados que en la realidad vivida por los seres cuidadores primarios y en los seres cuidados; son esas distintas formas de percibir la existencia, influido por el conocimiento de lo ancestral, los sentimientos y la sabiduría de la cultura que cada uno posee para expresarse en las múltiples formas que el cuidado lo acontece y lo requiere para dar el sentido cultural característico y diferenciado que se percibe en el modo de cuidar y la satisfacción de quien lo recibe y lo ofrece. Este aspecto fue valioso para la comunidad académica del programa de enfermería, porque ubicó epistémicamente la transculturalidad del cuidado como una mirada y forma de enseñar transdisciplinariamente, enseñando y ofreciendo el cuidado desde la cultura, sentimientos y pensamientos del ser cuidado para el mantenimiento de la vida y la salud, en la que estudiantes de enfermeria desde sus primeras experiencias formativas deben incursionar en la intervención holística que se requiere en el cuidado de la salud y de la vida.

    1999-01-01

    Full Text Available El presente trabajo se propone reflexionar sobre las reformas de los sistemas de salud y de políticas sociales en el marco de las así llamadas reformas del Estado. Com esta finalidad, se busca como punto de partida condensar distintas visiones explicativas de la crisis del Estado de Bienestar, presentes en la bibliografía produzida en la década de los 90. En el corazón de la crisis, las políticas sociales se encuentran profundamente cuestionadas. Lo que pretendemos mostrar es que este argumento posee una función específica, que es la de introducir mudanzas de carácter neoliberal en la política económica y para las cuales los instrumentos económicos utilizados van a generar la abstención del Estado en el plano social, la desregulación de las economías nacionales en favor del libre mercado y, fundamentalmente, el papel sobredimensionado del mercado financiero internacional. En este contexto, son analizadas las reformas de la seguridad social y de los sistemas de salud. La última parte del trabajo tuvo por objetivo enfrentar las dificultades que las políticas sociales presentan en el contexto actual, trayendo al centro del debate un mapeamiento de las alternativas posibles para el desarrollo de las políticas sociales y de salud.

    Full Text Available Existen bastantes evidencias para vincular la cultura del vino con el entorno y el desarrollo sostenible. En primer lugar, destaca que la cultura del vino es el reflejo del aprovechamiento vitivinícola del medio y, por tanto, refleja su efecto sobre el desarrollo social y económico de las regiones, lo que es plausible a través del devenir histórico de las mismas. Más recientemente, el aprovechamiento de la cultura del vino para su explotación a través de las experiencias enoturísticas, ha supuesto una revalorización de muchos territorios, impulsando el desarrollo social y económico. La cultura del vino no es sólo el eje temático de la actividad enoturística, sino que es su base y pilar esencial, por tanto, se relaciona directamente con la sostenibilidad ambiental, económica y social que subyace tras el enoturismo. Además, es importante tener en cuenta que gran parte de la importancia de la cultura del vino se centra en las señas de entidad asociadas a cada territorio, que aportan características distintivas y singulares, contribuyendo a la sostenibilidad cultural. En España, ACEVIN y el Rutas del Vino de España son claros ejemplos de como la cultura del vino es un motor del desarrollo sostenible de las regiones vitivinícolas.

    Full Text Available Riassunto - L’Autore ripercorre in chiave critica l’evoluzione delle politiche legislative in materia di lavoro, alla luce dell’attuale fase di crisi economico finanziaria. Nell’esaminare i principali interventi normativi attuati da inizio secolo, l’Autore mette in evidenza le scelte di metodo e gli elementi di continuità che accomunano i vari provvedimenti, individuandoli nell’affannosa ricerca del punto di equilibrio tra flessibilità e garantismo. La riflessione si chiude con alcuni interrogativi sulle ultime linee di riforma del mercato del lavoro e con l’auspicio che, anche al cospetto delle imprescindibili ragioni dell’economia, il diritto del lavoro possa continuare a svolgere il proprio tradizionale ruolo di disciplina di tutela della persona.   Abstract - The author analyzes, with a critically oriented approach, the development of the employment law, in the light of the current economic and financial crisis. In examining the main regulatory measures implemented since the beginning of the century, the author highlights the methodological choices and the elements of continuity that unite the various measures, focusing them in a hard research of a point of balance between flexibility and security. The discussion concludes with some questions about the last lines of the reform of the labor market and with the hope that, even in the face of compelling reasons of economy, labor law can continue to play its traditional role of governing the protection of person.

    2016-01-01

    Full Text Available El rápido desarrollo de mercados con productos competitivos de difícil diferenciación y consumidores mejor informados que demandan experiencias memorables, justifican estudiar los elementos sensoriales que pueden potenciar e influir positivamente sobre dichas experiencias. El objetivo de este artículo es analizar el estado del arte respecto a la gestión y uso del marketing sensorial sobre la experiencia del consumidor. El diseño de investigación es no experimental documental, con un tipo de estudio descriptivo, empleando fuentes de recolección de información secundarias, mediante un arqueo bibliográfico de revistas de impacto que figuran en bases de datos de libre acceso. Los resultados revelan la dominancia del sentido de la visión sobre la persuasión y las actividades de marketing, mientras que el sentido del olfato demuestra mayor influencia sobre el nivel de recuerdo y evocación de información. Se concluye la utilidad de jerarquizar por nivel de influencia las actividades de estimulación sensorial en marketing a partir del funcionamiento y participación de los sentidos humanos y poder combinar dichas estimulaciones como medio para maximizar la experiencia del consumidor y distinguir la oferta de valor, considerando el grado de diferenciación, la favorabilidad y la fuerza de la actividad sensorial basada en planeación estratégica empresarial.

En la fase de diagnóstico en las áreas de intervención del proyecto, más del 80 % de los agricultores no utilizaban la semilla del sistema formal; por lo tanto, las variedades obtenidas por los programas de mejoramiento no llegaban a la mayoría de los agricultores. Se buscó un mecanismo alternativo para introducir diversidad genética a las localidades mediante las ferias de diversidad, cuyo objetivo principal ha estado dirigido a facilitar el flujo de semilla de los institutos de investigaciones hacia el agricultor y viceversa. Posterior al desarrollo de las ferias de diversidad se continúa con la experimentación campesina en fincas y cooperativas, desarrollándose una amplia red experimental difícil de lograrse sin la participación de los productores.

    High rates of sex and drug risk behaviors have been documented among Latino migrant men in the U.S. Whether these behaviors were established in the migrants’ home countries or were adopted in the U.S. has not been described and has implications for prevention strategies. Quarterly surveys were conducted to gather information on selected sex and drug risk practices of Latino migrant men who arrived in New Orleans after Hurricane Katrina seeking work. Both kappa scores and McNemar’s tests were performed to determine if practice of these behaviors in home country was similar to practice post-emigration to the U.S. Female sex worker (FSW) patronage, same sex encounters (MSM), and crack cocaine use was more likely to occur post-rather than pre-emigration. Of those who ever engaged in these selected behaviors, most adopted the behavior in the U.S. (i.e. 75.8% of FSW patrons, 72.7% of MSM participants, and 85.7% of crack cocaine users), with the exception of binge drinking (26.8%). Men who were living with a family member were less likely to adopt FSW patronage OR=0.27, CI=0.10-0.76, whereas men who earned >$465 per week were more likely to adopt crack cocaine use OR=6.29 CI=1.29, 30.57. Interventions that facilitate the maintenance of family cohesion and provide strategies for financial management may be useful for reducing sex and drug risk among newly arrived migrants.

Fundida en un molde monovalvo que proporciona un acabado homogéneo a una sola de las caras, se integra metalúrgicamente en el grupo E 01 (cobres arsenicales propio de la Península Ibérica durante el Calcolítico y el Bronce Antiguo. Tipológicamente puede ser clasificada como integrante del grupo Carrapatas al que pertenecen un conjunto de alabardas procedentes del N.E. de Portugal (Bragança y Tras os Montes del que se conocen escasos testimonios fuera del área característica. Especialmente significativo es el hallazgo de la finca de la Paloma (Pantoja, Toledo que muestra la asociación entre las alabardas Carrapatas y elementos propios del campaniforme tardío de España y Portugal, circunstancia que permite fechar el tipo entre el 1700-1500 a. de J.C., datación similar a las fechas admitidas para las alabardas irlandesas con las que algunos autores ven posibles relaciones. La existencia de alabardas grabadas en estelas más tardías o en rocas al aire libre plantea el problema de su perduración. No obstante, el carácter simbólico de las armas grabadas puede hacer que sea solamente la imagen representada la que superviva, aunque el arma como tal haya perdido vigencia. La alabarda del Manzanares, junto con las de Pantoja, señala la presencia en la Meseta Sur de elementos metalúrgicos propios del N.W. de la Península en un momento sincrónico con las fases finales del campaniforme.ABSTRACT: We study a metallic halberd found in an indeterminate place in the valley of the river Manzanares (Madrid.

    2015-05-01

    Full Text Available El objetivo de este artículo es comparar y contrastar algunos conjuntos de vivienda modernos en ciudades europeas del Oeste (“capitalistas” y del Este (“socialistas”. Nuestro trabajo se centra en conjuntos de vivienda masiva construidos en el periodo de crecimiento urbano acelerado que tuvo lugar en Europa principalmente en las décadas de los años 60 y 70 del pasado siglo. El punto de partida más obvio es que las ciudades socialistas son diferentes de las europeas occidentales por la distinta naturaleza de sus políticas urbanas, el sistema de planificación económica socialista centralizada, la ausencia de un mercado del suelo libre, el impacto de la industrial­ización en el sector de la construcción, etc. Sin embargo, hay muchos conceptos en urbanismo, así como en los procesos urbanos, que fueron compartidos en ambos sistemas políticos e ideológicos. El artículo ofrece una perspectiva comparada de la naturaleza de esos conjuntos residenciales modernos construidos a ambos lados del Telón de Acero –Housing Es­tates en UK, Grands Ensembles en Francia, Großsiedlungen en Alemania, Polígonos en España o los grandes conjuntos residenciales socialistas en los países del Bloque del Este– con el fin de entender mejor si –y hasta qué punto– las formas urbanas de dichos conjuntos son el resultado de la cultura internacional del urbanismo moderno.

    La doctora MarthaLucía Tamayo comparte muchas inquietudes alrededor del Libro del Almismo, el Libro del Pensar; de dónde salió ese nombre; de juntar en medicina y en genética a tres escritores como lo son Jorge Luis Borges, Macedonio Fernández y Julio Cortázar. Su conferencia dice así:

    El término almismo fue ideado por Macedonio Fernández porque defendía mucho el ensimismamiento y el pensamiento hacia el interior, mirar hacia adentro; cada uno somos un “sí mismo” que nos hace diferentes aunque al mismo tiempo podemos ser iguales. Todos tenemos esa parte interior que la medicina debe trabajar y que no puede olvidar.

    “El Libro del Almismo, el libro del pensar” nos lleva a replantear y a repensar un poco la medicina que queremos, una medicina vuelta a pensar.

    Quiero contarles la historia de cómo se llegó a este libro y por qué y para qué se sigue trabajando en estos temas: Después de mi internado y de un trabajo un poco triste de rural, volví al Instituto de Genética y a la Universidad Javeriana en donde encontré al doctor Bernal y un espacio que estaba buscando para esa medicina diferente que quería, con un grupo de personas que me permitía no sólo ver la medicina sino ver muchas otras cosas más; había espacio para la literatura, para Mafalda, para hablar de niños, de locos, había incluso tiempo para hablar de medicina dentro del golf, de carros antiguos y de todo eso fui aprendiendo.

    Eso era lo que estaba buscando. Una medicina que diera espacios diferentes, que fuera más humanizada. Rápidamente me ubiqué y me quedé! No me arrepiento en lo absoluto de haberme quedado porque fue, ha sido y sigue siendo, una experiencia enriquecedora, de muchas vivencias importantes. Sabía exactamente dónde estaba y sabía que había que seguir rápido y había que trabajar muchos aspectos de esa medicina que estábamos buscando y de esa genética especial.

    Full Text Available A diferencia de otros países americanos, el Perú carece de una memoria nacional de sus guerras civiles decimonónicas. Estas han sido opacadas por la avasalladora memoria de la Guerra del Pacífico, que el Perú y Bolivia perdieron ante Chile (1879-1883. El presente ensayo se propone rescatar del olvido a las guerras civiles peruanas del siglo XIX, empezando por las guerras de la independencia. Las preguntas que planteamos están motivadas por la guerra reciente que desató el Sendero Luminoso entre 1980 y fines de la década de 1990, en la que los campesinos andinos asumieron las funciones represivas del Estado al tomar las armas para derrotar a la insurgencia senderista. Esta situación exhibe interesantes paralelos con las guerras civiles del siglo XIX. Proponemos que el estudio de las guerras civiles decimonónicas del Perú, a la luz de la reciente guerra interna, ofrece una oportunidad fecunda para discutir las nociones de ciudadanía y pertenencia, la relación entre guerra y la constitución del Estado, así como los alcances y límites del concepto weberiano del Estado como el ente que monopoliza la violencia legítima. Subrayamos la importancia de la organización civil de las poblaciones rurales en el devenir de la guerra y, más ampliamente, en la construcción del Estado.

    1997-01-01

    Full Text Available FUNDAMENTO: Las parasitosis intestinales en los niños constituyen un problema de salud pública que debe ser valorado periódicamente en cada región. En este trabajo se aborda, por primera vez en la región natural del Valle del Guadalquivir, un estudio amplio sobre la prevalencia del parasitismo intestinal en la población infantil de la zona. MÉTODOS: Durante el período 1994-1996, mediante análisis coprológico y método de Graham, se ha estudiado a 1.917 niños y niñas asintomáticos, con edades comprendidas entre seis y diez años, residentes en veinte localidades del Valle del Guadalquivir. RESULTADOS: El índice global de parasitación ha sido del 27,12 %. Las especies parásitas detectadas, así como sus prevalencias fueron: Enterobius vermicularis (20,44%, Giardia lamblia (5,05%, Entamoeba coli (2,45%, Endolimax nana (1,61%, Entamoeba histolytica (0,31%, Entamoeba hartmanni (0,05%, Iodamoeba bütschlii (0,05%. CONCLUSIONES: La prevalencia global encontrada es similar a la de otras regiones españolas, aunque quizás pueda considerarse algo más favorable. No se detectan geohelmintos, debido posiblemente a la mejora de la infraestructura higiénico-sanitaria y a los efectos de la prolongada sequía en la zona. La giardiasis, a diferencia de las restantes protozoosis, mantiene una prevalencia relativamente alta.

    Full Text Available Se ha considerado el comportamiento del sector eléctrico como un factor de gran trascendencia en desenvolvimiento de la economía de un país. Sin embargo, es notable el desconocimiento de algunas personas no especialistas es esta temática, de los conceptos básicos y de la organización intrínseca de este sector. Por lo tanto, resulta conveniente la realización de un artículo que informe de manera descriptiva sobre la naturaleza y funcionamiento del sector eléctrico en Colombia, como punto de partida para posteriores estudios y profundos análisis de temas relacionados con este sector. Entre los aspectos básicos que una persona debe conocer para estar en capacidad de entender y argumentar sobre el comportamiento del sector eléctrico en Colombia podemos citar, entre otros, los siguientes: antecedentes e historia del sector, agentes e instituciones del mercado, variables importantes en la toma de decisiones, contratos de corto y largo plazo, y finalmente algunos procedimientos que actualmente se encuentran en discusión, los cuales podrían cambiar el funcionamiento del Mercado de Energía Mayorista en Colombia

El objetivo del trabajo fue determinar la prevalencia de helmintos intestinales en perros con dueño del departamento del Quindío. Materiales y métodos. Estudio descriptivo prospectivo. Se aplicó una encuesta epidemiológica a los propietarios de los perros. Se recolectaron muestras de heces de los caninos registrados en la jornada de vacunación antirrábica del 2003 en el departamento del Quindío. Las muestras de materia fecal frescas fueron analizadas utilizando la técnica de diagnóstico de Ritchie. Resultados. Se analizaron 324 muestras de heces caninas; el 67,6% de los perros eran de razas puras y el 32,4% razas mestizas. Se encontró una prevalencia del 22,2%; Ancylostoma caninum fue el parásito más frecuente, 13,9%. También se observó Trichuris vulpis, 4,3%; Toxocara canis, 2,5%, y Strongyloides stercoralis, 4,0%. El 2,46% de las mascotas se encontraron multiparasitadas. Conclusión. La frecuencia de helmintos intestinales en el departamento del Quindío fue de 22,2% y la presencia de estos parásitos coincide con factores como la edad y la permanencia del canino en la calle, entre otros. Por esta razón, es necesario establecer programas de vigilancia y prevención en la población humana y canina.

Se examina la competitividad del Valle en relación con Colombia y con el resto del mundo. Se cuestiona la insistencia en una estrategia exportadora como dinamizadora del desarrollo económico. Se identifica que una gran parte de la población está excluida de los beneficios del desarrollo económico. Para construir un modelo de desarrollo que incluya a esta población se recomienda recuperar la senda de la industrialización, invertir en el capital humano (educación de alta calidad, salud, salubridad y nutrición, e invertir en infraestructura. La participación del Estado en estas inversiones sociales es necesaria para disminuir la desigualdad y aumentar el crecimiento económico.

    Although disaster exposure has been linked with increased child aggression by previous reports, population-level trends are unknown. Pre- to post-Katrina changes in violence-related behaviors among New Orleans high school youth (ages: 12-18 years) were assessed. Data from the 2003 (pre-Katrina), 2005 (pre-Katrina), and 2007 (post-Katrina) New Orleans Youth Risk Behavior Survey (n = 5,267) were used. Crude comparisons across years of population characteristics and violence behavior prevalence were made with χ(2) analyses. Changes in violence-related behaviors over time were assessed with logistic regression models including indicators for survey years and controls for compositional changes. Age, gender, and race/ethnicity of school-attending youth were stable across years. In models controlling for demographics, most behaviors were stable over time. Some changes were observed for all groups; dating violence and forced sex increased before the storm, whereas weapon-carrying and missing school as a result of feeling unsafe decreased after the storm. Among African American adolescents only, being threatened at school increased before Katrina. Results do not support significant population-level increases in violent behavior post-Katrina among school-attending youth in New Orleans. Factors that buffered New Orleans students from post-Katrina violence increases, such as population composition changes or increased supportive services, may explain these findings.

    Full Text Available Se determinó la respiración del suelo (RS en una comunidad sucesional de pastizal de Holcus lanatus y Anthoxanthum odoratum en la franja altoandina de la cuenca del río Pamplonita, Norte de Santander, Colombia. Las medias mensuales de la RS fueron unimodales de día y de noche; la anual diurna fue de 118,44 mg CO2 m-2 h-1; y la nocturna, de 140,57 mg CO2 m-2 h-1. La diferencia entre estos dos valores se atribuyó a un incremento del brillo solar y a una disminución del recorrido del viento entre septiembre y diciembre de 2006 que condujo a un aumento de la tasa de evaporación. La RS nocturna se correlacionó con la humedad relativa y la temperatura máxima del aire y la diurna con el recorrido del viento. La RS acumulada (diurna y nocturna mostró una tendencia lineal con respecto al tiempo. La producción anual diurna de carbono, con base en la RS acumulada anual, se estimó entre 32,67 y 40,73 y la nocturna entre 35,65 y 43,02 g de C m-2.

Con este fin se propone la adaptación del marco teórico sobre modelos de negocio, al tiempo que se desarrolla una metodología para el análisis longitudinal en esta primera etapa de la vida de una empresa, utilizando un caso revelador. Ello permite confirmar muchos de los hallazgos teóricos del campo de estudio e identificar nuevas cuestiones de investigación. Así, se pone de manifiesto la importancia de desvelar qué factores influyen en la evolución del proceso emprendedor a través del análisis de la evolución del modelo de negocio que subyace, y cómo se ajustan los elementos internos de la empresa con los del entorno para ir configurando un proyecto empresarial en su fase temprana. El trabajo contribuye a mitigar la necesidad de desarrollar estudios de corte longitudinal, al incluir la dimensión temporal en el modelo de negocio, cuestión escasamente abordada en la literatura.

    Full Text Available El propósito de este artículo es mostrar el valor que cobra en el Libro del caballero Zifar la definición del consejo como elemento fundamental del molinismo. El análisis permite distinguir no solo la afirmación de una palabra linajística ejemplar sino también la importancia del consejo del verdadero amigo, y en particular, el de la mujer o del caballero. A través de la valoración de la prueba que le tiene que imponer el rey al consejero se vislumbra además la imagen de este consejo privado que se impuso bajo el reinado de Alfonso XI y cuyo papel no fue sino confortar el poder de la realeza.Le propos de cet article est de montrer l’importance que revêt dans le Livre du chevalier Zifar la définition du conseil comme trait essentiel du molinisme. L’analyse permet non seulement de mettre en évidence l’affirmation d’une parole lignagère exemplaire mais aussi de distinguer le conseil de l’ami véritable, en particulier celui de la femme ou du chevalier. À travers la valorisation de l’épreuve que le roi se doit d’imposer au conseiller, on entrevoit en outre l’image du conseil privé qui s’imposa sous le règne d’Alphonse XI et dont le rôle fut de conforter le pouvoir de la royauté.

    Full Text Available La integración comercial del TLCAN puede tener efectos positivos y negativos en las economías que la promueven, dependiendo en gran medida del grado de apertura, el tipo de competencia que se genere y el nivel de desarrollo de los países. El propósito de este trabajo es medir los resultados del comercio agropecuario en el contexto del TLCAN. Se prueba el análisis en los indicadores de creación y desviación de comercio, de especialización comercial y competitividad y el impacto por el cambio en las exportaciones e importaciones agropecuarias y productos seleccionados.

    Full Text Available En Chile, el principal insumo usado como alimento para abalones son las algas Gracilaria chilensis y Macrocystis pyrifera. Estas algas experimentan una notable baja de disponibilidad en otoño e invierno, lo cual trae consigo un aumento considerable de los precios, al tener que depender del abastecimiento desde áreas cada vez más alejadas de los centros de cultivo de abalones y, eventualmente, generando impactos ecológicos indirectos en sus poblaciones. El objetivo fue elaborar y evaluar un ensilado del alga G. chilensis para la alimentación de abalón rojo (Haliotis rufescens, determinando la cantidad de lixiviados generados durante el proceso, el cambio en la composición proximal del alga, la preferencia y consumo del abalón rojo de ensilado de G. chilensis. Se logró un producto ensilado de buenas características físicas, químicas y de conservación, así como una buena aceptación por parte del abalón.

  3. Relación entre el Grado de Aplicación del Agua del Riego y la Estructura del Suelo.

    1975-06-01

    Full Text Available Algunos suelos sueltos, sin estructura, tienden a consolidarse como un resultado del artefacto que produce el riego o la lluvia. Una de las manifestaciones de la estructura del suelo es la densidad aparente, la cual está relacionada con la consolidación y reducción de espacios porosos en el suelo. La consolidación causada por la adición de agua al suelo puede tener el mismo efecto de la compactación causado por la labranza o por los equipos agrícolas. Se hicieron ensayos para determinar la relación entre los diferentes grados de aplicación del agua y la consolidación del suelo debida al riego, y se determinó para cada caso, la densidad y la porosidad. Se encontró que la resistencia del suelo, o sea, el mantenimiento de una estructura dada, es muy sensible al contenido y cambios en el incremento de la humedad, haciendo que se disminuya la macroporosidad con el consecuente aumento de la densidad aparente. 

  4. Transferencia microquirúrgica hemipulpar del hallux en la reconstrucción del pulgar

    José-Manuel Rodríguez-Vegas

    Full Text Available Introducción y Objetivo. La transferencia hemipulpar del hallux permite excelentes reconstrucciones de pulgar porque ofrece tejidos blandos de alta calidad, contorno pulpar casi normal y recuperación sensitiva satisfactoria sin necesidad de reorientación cortical. Además, a diferencia de colgajos locales y regionales, evita la agresión adicional a una mano ya lesionada, optimizando así el período de rehabilitación y el resultado final. El artículo revisa la experiencia del autor en la técnica y compara el procedimiento con otras opciones reconstructivas. Material y Método. Realizamos una revisión retrospectiva de 16 pacientes sometidos a transferencia hemipulpar del hallux en el período 2007-2013. Todos los pacientes fueron varones, con una edad media de 34 años y una alta demanda funcional (trabajadores manuales con traumatismo laboral. La técnica fue indicada en defectos mayores del 50% de la superficie pulpar del pulgar en pacientes sin factores de riesgo asociados relevantes. En 3 de los casos el defecto pulpar asoció un defecto óseo de falange distal de tamaño suficiente para aconsejar la transferencia combinada osteo-pulpar. Resultados. Quince de los 16 colgajos sobrevivieron sin incidencias postoperatorias. Un colgajo sufrió trombosis arterial con retirada del colgajo y cirugía adicional de cobertura. En 2 pacientes se realizó revisión estética del colgajo de manera diferida. Excepto en el caso fallido, todos los pacientes volvieron a su actividad laboral previa con excelente recuperación funcional de la mano. El cierre de la zona donante se realizó mediante cierre directo (12 pacientes o injerto cutáneo (4 pacientes. Ninguno de los pacientes, independientemente del tipo de cierre del defecto en el pie, refirió problemas en la deambulación o apariencia estética del pie. Conclusiones. La reconstrucción de defectos pulpares del pulgar mediante transferencia hemipulpar del hallux permite un excelente resultado

    2007-01-01

    Full Text Available La existencia de un ingrediente contractual en el origen de la responsabilidad del productor en el presente siglo sugiere una necesaria referencia al derecho contractual del S. XIX. A diferencia del S. XVIII en el cual, resulta sumamente difícil alcanzar un conocimiento pleno del common law, debido al escaso n úmero de demandas judiciales y a la casi inexistente trascendencia del precedente judicial, en el S. XIX se asiste a un cambio profundo debido a la expansión económica. Este fenómeno determinó un incremento paralelo de las demandas judiciales, gran parte de las cuales tenía como fundamento la mala calidad del producto vendido. Este período, caracterizado por el movimiento en las operaciones económicas que suscita el desarrollo industrial, se convierte en el contexto ad hoc para la difusión y la consolidación del principio de la privity of contract que en los sistemas de derecho escrito viene a corresponder al principio de la ‘relatividad contractual’. La verificación de profundos cambios en el ámbito socioeconómico dará inicio a toda una etapa de transformación de la responsabilidad del productor, destacando los casos que han sentado precedentes en esta evolución con una orientación clara hacia la tutela de las víctimas de daños derivados de productos defectuosos.

    Full Text Available El objetivo de esta investigación es conocer las representaciones culturales frente al proceso de enfermedad en los pacientes provenientes del área rural de Norte de Santander, que egresaron del servicio de Urgencias del Hospital Universitario Erasmo Meoz (ESE HUEM. EL estudio es de enfoque cualitativo de abordaje etnográfico. Se definió la muestra de tres informantes, de modo intencional. El método para la recolección de la información que se utilizó en esta investigación fue la observación, las notas de campo y la entrevista a profundidad, que permitió aprender y conocer más a fondo como los pacientes del área rural conceptualizan la experiencia de estar enfermos y cuáles son los cuidados culturales que aplican durante este proceso. Los resultados de esta investigación permitieron observar que la enfermedad es un enemigo común para las personas del área rural y para mantener el equilibrio de la persona con el entorno natural estos pueden a travesar cuatro fases: fase tomásica, fase de rituales culturales, fase auxilio multidisciplinario y fase reestructuración del cuidado. La cultura es definitivamente el juez que califica las acciones de las personas, para unos la enfermedad es un castigo, por el mal comportamiento que han tenido en un momento de su vida y para otros es simplemente una prueba para que Dios perdone sus pecados. Así que el acontecimiento puede ser el mismo pero la cultura transforma la definición del evento.

  9. Franco Modigliani e la teoria del ciclo vitale del consumo

    2005-06-01

    Full Text Available Nei primi anni ’50, Franco Modigliani e il suo studente Richard Brumberg elaborarono una teoria della spesa fondata sull’idea che gli individui effettuano scelte intelligenti su quanto desiderano spendere a ogni età, con il solo limite delle risorse disponibili nel corso della loro vita. Attraverso l’accumulo e il decumulo delle attività, chi lavora può provvedere alla propriapensione e, più in generale, può adattare i propri modelli di consumo alle esigenze che sipresentano alle diverse età, indipendentemente dal reddito disponibile in ogni momento della suavita. Questa semplice teoria conduce a previsioni rilevanti e non scontate per l’economia nel suo complesso, ad esempio che il risparmio nazionale dipende dal tasso di crescita del reddito nazionale e non dal suo livello, e che esiste una semplice relazione tra il livello della ricchezza nelsistema economico e la lunghezza del periodo trascorso in pensione. Tali previsioni, non verificabili negli anni ’50, hanno trovato considerevole sostegno empirico in successivi lavori di Modigliani e di altri ricercatori. Sebbene nel corso degli anni la teoria del consumo abbia subitonumerosi attacchi, i più recenti dei quali mossi da una coalizione di psicologi ed economisti,l’ipotesi del ciclo vitale rimane una parte essenziale del pensiero degli economisti.

    Full Text Available The aluminium dust is a hazardous waste from the secondary aluminium remelting industry. A stabilization/solidification process was developed at CENIM with the aim of decreasing its reactivity. Gypsum was used as a binder material. This work summarizes the study of the thermal behavior of the aluminium dust stabilized with gypsum, in order to establish the influence of the residue in the reactions of hydration/dehydration of the gypsum during the hardening process, namely: partial dehydration of calcium sulphate dihydrate, dehydration of calcium sulphate hemi-hydrate, dehydration of aluminium hydroxide and anhydrite soluble/anhydrite insoluble transformation. The activation energy associated to all those reactions was determined by Differential Scanning Calorimetry.

    El polvo de aluminio (pAl es un residuo peligroso procedente de la metalurgia secundaría del aluminio. Con objeto de reducir la reactividad del mismo, en el CENIM se ha desarrollado un proceso de estabilización/solidificación mediante su fraguado con yeso. En este trabajo se presenta el estudio del comportamiento térmico del pAl estabilizado con el yeso, con el fin de establecer la influencia del residuo en las reacciones de hidratación/deshidratación del yeso durante el proceso del fraguado, a saber: deshidratación parcial del sulfato cálcico dihidrato, deshidratación del hemihidrato, deshidratación del hidróxido de aluminio y transformación de anhidrita soluble en anhidrita insoluble. Asimismo se ha estudiado la cinética asociada a cada una de las reacciones anteriormente mencionadas mediante Calorimetría Diferencial de Barrido.

    Full Text Available En el departamento del Valle del Cauca, la distribución de Bosque Seco Tropical (BsT se ha asociado al valle geográfico del río Cauca ubicado en la zona plana. Actualmente en esta zona, su cobertura se ha reducido a pocos relictos que se encuentran bajo alguna figura de conservación y mantienen áreas representativas de las formaciones vegetales sssstípicas de este bioma. Este trabajo se enfocó en el reconocimiento de la distribución espacial de formaciones vegetales de BsT en el departamento del Valle del Cauca. Se empleó información cartográfica secundaria para reconocer los biomas, ecosistemas y usos del suelo del área de estudio y en zonas adyacentes del piedemonte y montañas. Un modelo digital de elevaciones fue utilizado para realizar análisis altitudinales. En un sistema de información geográfico se aplicaron técnicas de geoprocesamiento y análisis geoespacial entre la información cartográfica y satelital. Los resultados evidencian que pese al avanzado deterioro de las coberturas de bosque seco en la zona plana, alrededor del 80 % se localiza en ecosistemas de montaña, específicamente en zonas de transición hacia bosques húmedos. A futuro, el potencial de estas áreas deberá evaluarse para ser incluidas en estrategias de conservación y restauración del bosque seco así como en el diseño de procesos adaptativos frente al cambio climático.

    Full Text Available RESUMEN: La mayor parte de los trabajos sobre la arqueología del Plio-Pleistoceno en Africa se centran en la evidencia del valle del Rift. Allí existen extensas columnas crono-estratigráficas que permiten contextualizar de forma fiable los conjuntos arqueo-paleontológicos y reconstruir así la secuencia evolutiva de nuestro género. Se suele obviar de esa forma la evidencia del resto de África, donde existen grandes áreas sedimentarias muy poco conocidas desde un punto de vista arqueológico. En este trabajo se reflexionará sobre el registro arqueológico plio-pleistocénico en las zonas alejadas del valle del Rift, y se tratará de reconstruir cómo fue la primera colonización del continente africano.ABSTRACT: Most of the works about the African Plio-Pleistocene are focused on the Rift Valley evidence. In this area there are long chrono-stratigraphical columns that build reliable contexts for the archaeo-paleontological sites, providing the reconstruction of the evolutionary sequence of our Genus. Evidence on the rest of Africa, where there are poor-known sedimentary areas from an archaeological point of view, is usually dismissed. In this work we will reflect on the Plio-Pleistocene record beyond the Rift Valley, trying to reconstruct the first settlement of the African continent.

De las observaciones realizadas se concluye: 1) El número promedio de moléculas de OH en la coma durante 37 días de observación fue de (8.9±3.5)x1034 moléculas, lo que implica una tasa de producción promedio de OH de 1.8x1029 moléculas seg-1 y consecuentemente una pérdida de masa promedio de 17±6 toneladas seg-1 . Este valor está de acuerdo con las mediciones realizadas por las sondas Vega y Giotto. 2) El monitoreo desde el lAR revela la existencia de variaciones bruscas en los flujos de absorción del OH. Estas variaciones son consistentes con los modelos que representan la producción gaseosa a partir de ejecciones y/o desprendimientos discretos de materia congelada del núcleo. 3) Las variaciones en la densidad de flujo son consistentes con las estimaciones de los tiem- pos de vida medios del H2O y del OH en presencia del campo de radiación solar. 4) Se encuentra una correlación entre la intensidad del flujo absorbido y anisotropías en Ia dinamica de la coma.

    Full Text Available Aunque el desarrollo de la neurología y psicología se remonta cientos de años, la investigación en neurociencias a gran escala es un logro del siglo XX. En estos últimos 100 años, se ha generado gran parte del cuerpo de conocimientos que sustenta nuestra visión general del sistema nervioso. Numerosas características bioquímicas, fisiológicas, farmacológicas y estructurales del cerebro han sido descritas, primero en invertebrados y luego en vertebrados. En los últimos años, esfuerzos importantes han sido destinados también a definir las bases de las funciones de percepción, emoción, memoria, atención y cognición. Por último, tanto los métodos experimentales como la observación de individuos (a menudo pacientes con lesiones definidas nos han permitido asociar ciertas funciones a regiones neuroanatómicas específicas. Como resultado, hoy tenemos un campo de estudio del cerebro y las ciencias cognitivas (mente tan bullente en información como en incógnitas de compleja solución. El misterio de la relación mente/cerebro es un viaje apasionante a través de un laberinto de información, hipótesis y teorías, que captura tanto al estudioso de la biología como al matemático o al filósofo. De hecho, solo parece razonable enfrentar tamaña tarea desde las trincheras de la interdisciplinariedad, dada la multiplicidad de los componentes y su naturaleza que solo emerge desde un todo coherente.

    Full Text Available Durante el embarazo aumentan el metabolismo basal, el consumo de O2, la frecuencia cardíaca, el volumen sistólico, el volumen minuto y la volemia y disminuyen la tensión arterial y la resistencia periférica. Diferentes estudios han demostrado que durante este período la posibilidad de que ocurra una arritmia cardíaca o se produzca la exacerbación de una arritmia preexistente es mayor. No obstante, en su enorme mayoría carecen de importancia pronóstica tanto para la madre como para el feto. La taquicardia ventricular del tracto de salida del ventrículo derecho es una arritmia poco frecuente y su aparición se ha correlacionado con el aumento del tono adrenérgico. Se presentan los casos de dos pacientes que mostraron en el curso de la gestación reiterados episodios de taquicardia ventricular del tracto de salida del ventrículo derecho. Se analiza la asociación del embarazo con la ocurrencia de trastornos del ritmo cardíaco.

    Full Text Available Para la recolección y análisis de la información se utilizaron la Etnografía focalizada y la técnica de Spradley y la teoría de la diversidad y la universalidad de los cuidados culturales de Leininger se tomó como referente teórico. Su objetivo fue describir los cuidados que brindaban las parteras tradicionales a partir de creencias y prácticas en las mujeres durante el parto en la zona rural de la región del valle del río Cimitarra, Magdalena Medio. El estudio se desarrolló en el valle del río Cimitarra y la ciudad de Barrancabermeja. Participaron siete parteras tradicionales y se recolectaron los datos mediante entrevista etnográfica y observación participante entre los años 2007 y 2008. El tema central es " El saber de la partera tradicional del valle del río Cimitarra: cuidando la vida" y cinco dominios culturales: alistarse para la atención del mismo, identificar el momento del parto, ayudar a la mujer a parir, proteger al bebé después del nacimiento y proteger a la mujer después del nacimiento. Cuidar la vida se relaciona con la necesidad de " sobrevivir" a pesar de la guerra, la violencia y el abandono estatal. Las acciones de cuidado se fundan en creencias culturales, la cotidianidad del trabajo del campo, la tradición oral y la invocación divina en medio del complejo contexto ambiental, la incertidumbre del conocmiento y el miedo a problemas legales.

    Full Text Available The Olalde spring is the main drain of the karstic system of the Iimestome of San Miguel de Ereñozar; the aquifer is also recharged through sinks (ponors, by the surface run off from drained closed basins, partially occupied by impermeable materials. The mean flow of the spring is 240 I/sec, with a very high variability: the flow was 2633 I/sec at the beginning of the recession curve analyzed here and 18 I/sec the last day considered. The value of the depletion coefficient α is 0.032 day-1 and the duration of the recession curve "sensu stricto" is 21.5 days. The values of the velocity of infiltration coefficient á¼  and the heterogeneity coefficient ξ are, respectively, 0.0465 and 3.49 day-1. The parameters i (=0.114 and k (=0.025 suggest a very fast recession and a very poor regulation power; this behaviour is typical of intensely karstified systems with a very well developed subterranean drainage network which are characteristic of the realm of huge spelaeological caves. These facts reveal that the prospects of regulation of the spring are not very promising and would involve, in any case, a small part of the whole discharge.El manantial de Olalde es la principal surgencia del sistema kárstico constituido por las calizas de San Miguel de Ereñozar; el acuífero es recargado además, a través de sumideros, por la escorrentía superficial de cuencas endorreicas ocupadas parcialmente por materiales impermeables. El caudal medio del manantial es de 240 l/seg con una notable variabilidad: el caudal era de 2633 l/seg al comienzo de la decrecida estudiada en este trabajo y de 18 l/seg el último día considerado. El coeficiente de agotamiento α tiene un valor de 0.032 día-1 y la duración de la decrecida propiamente dicha es de 21,5 días.
