  1. El proyecto AUGER

    NASA Astrophysics Data System (ADS)

    Etchegoyen, A.

    Hace ya más de 30 años en Volcano Ranch, EE.UU., un extenso chubasco cósmico (ECC) fue detectado con energía en exceso de 1020 eV. Desde entonces, observatorios ubicados en Haverah Park del Reino Unido, Yakutsk de Rusia, AGASA de Japón y Dugway de EE.UU. también han observado ECC con energías mayores que 1020 eV. Poco se sabe de dichos rayos, y en particular cuál es la naturaleza del primario, de dónde provienen, y cómo son acelerados, pero su naturaleza ultrarelativista excluye la mayoría de las respuestas dejando sólo algunas plausibles de ser investigadas experimentalmente. Grupos de científicos de 20 países están trabajando con el fin de construir dos arreglos de detectores gigantes, uno en cada hemisferio a lo largo de 3000 km2 c/u. Dichas dimensiones son necesarias debido al flujo estimado de 1 rayo cósmico/centuria/km2/sr. La sede del Observatorio del Sur es la Argentina. El proyecto fue nombrado Pierre Auger en conmemoración del célebre físico francés que detectó por primera vez chubascos cósmicos en 1938. El proyecto focaliza su interés en rayos cósmicos con energías mayores que 1020 eV.

    In this paper we briefly describe a joint scientific and technological effort between Argentina and Brazil, whose first goal is to install and run, in the northwestern part of Argentina, a millimetre and submillimetre observa- tional facility. In the long run, we would like to incorporate this dish to existing ones (ALMA, APEX, ASTE) in the northern extreme of Chile, to be able to carry out, for the first time in Latinamerican soil, very long base- line interferometry at mm/submm wavelengths. We also succintly mention a long term campaign that is under way in order to monitor the transparency of the atmosphere at those wavelengths. The science that can be accom- plished with this instrument, the technology transfer spin-offs related to this project, and the scientific and strategic importance of this project within both the Argentinean and Latinamerican radioastronomy is described.

  14. Proyecto para la medición sistemática de seeing en CASLEO

    NASA Astrophysics Data System (ADS)

    Fernández Lajus, E.; Forte, J. C.

    La calidad del seeing astronómico es ciertamente uno de los parámetros mas importantes que caracterizan el sitio de un observatorio. Por tanto se desea determinar si el alto valor de seeing observado con el telescopio de 2.15 m se debe a efectos internos y/o del entorno a la cupula o si se debe simplemente al seeing propio del lugar. El actual mecanismo de refrigeración del espejo primario del 2.15, parece haber mejorado notablemente la calidad del seeing. Sin embargo se hace necesario saber hasta que punto el valor del seeing puede ser mejorado. La primera etapa del proyecto consistió en la puesta a punto del telescopio emplazado para este propósito y la adquisición de las primeras medidas tentativas de seeing.

    To report the prevalence of visually significant cataract and cataract surgery and to determine demographic and socioeconomic factors that influence use of cataract surgery in a US Hispanic population. Proyecto VER is a population-based study of Hispanic individuals, 40 years or older, living in southern Arizona. Visual acuity was measured monocularly, and a dilated ophthalmic examination was performed to determine lens opacities. Visually significant cataract was defined as severe levels of opacity and acuity worse than 20/40. Risk factors were compared between those who obtained cataract surgery in the past and those having visually significant cataract. A majority of the 4774 participants in this study were of Mexican descent; 2.8% had visually significant cataract and 5.1% had undergone bilateral cataract surgery. Among those currently or previously needing surgery, having medical insurance (odds ratio, 2.88; P<.001) and speaking English (odds ratio, 1.80; P = .04) were significantly associated with having obtained surgery in the past. Visually significant cataract appears to be high among US Hispanic individuals of Mexican descent, as evidenced by rates of cataract and cataract surgery. Language and financial barriers in this population impede access to surgery. Further work to remove these barriers and provide sight restoration is warranted among Hispanic individuals of Mexican descent living in the United States.

  17. Elucidating empowerment in El Proyecto Bienestar (the Well-Being Project).

    PubMed

    Postma, Julie

    2008-05-01

    This paper describes differences in how socioculturally diverse participants in one community-based participatory research project negotiated 'empowerment', and the implications of those differences for nurses involved in farmworker health and safety efforts. Internationally, empowerment and community participation are increasingly being used as strategies to reduce health disparities. Theories of empowerment vary in the academic literature and their connotations vary across cultures. Study participants were part of El Proyecto Bienestar, a community-based participatory research (CBPR) project whose aim was to identify and respond to occupational and environmental health threats in one Mexican-American farmworker community in the United States of America. Participant observation was used to audiorecord 18 participants in the third year (2006) of this 4-year project discussing future project activities. Discourse analysis was used to analyse the transcripts. While participants agreed that 'empowerment' was central to the project, they had different perspectives on what the term meant and the role that the project should play in empowering the farmworker community. Empowerment discourses positioned the project in three ways: (1) as an instrument used to strengthen farmworkers' collective political voice, (2) as an instrument used to represent multiple community interests and (3) as an instrument used to advocate on behalf of farmworkers. Individuals used multiple discourses signifying the complexity in participants' roles and obligations. Balancing power and developing knowledge collaboratively requires understanding multiple approaches to empowerment. Community empowerment as an outcome should not come at the expense of individual empowerment as part of the CBPR process.

    The prevalence rate of diabetes is probably higher in Hispanics than in Caucasians, although there is controversy about differences in the risk of diabetic retinopathy. The purpose of the study is to determine the prevalence rates of diabetes and diabetic retinopathy in a population-based study of Hispanics aged > or = 40 years. Proyecto VER is a random sample of Hispanic populations aged > or = 40 years in Arizona. A total of 4,774 individuals (71.6% of the eligible sample) completed the examinations. Diabetes was defined as self-report of a physician diagnosis or HbA(1c) value of > or = 7.0%. Diabetic retinopathy was assessed on stereo fundus photographs of fields 1, 2, and 4. The prevalence rate of diabetes in the Hispanic community (individuals > or = 40 years of age) was 22%. The prevalence rate of diabetic retinopathy (DR) was 48%; 32% had moderate to severe nonproliferative and proliferative retinopathy. DR increased with increasing duration of diabetes and increasing level of HbA(1c). The prevalence rate of DR-like changes in the sample of individuals without diabetic retinopathy was 15% and was not associated with hypertension, systolic blood pressure, or diastolic blood pressure. The prevalence rate of diabetes in this population of Hispanics is high, almost twice that of Caucasians. The prevalence rate of DR is high but similar to reports in a Caucasian population. The prevalence rate of 9% moderate to severe retinopathy in the newly diagnosed group suggests that efforts to improve detection and treatment of diabetes in Hispanics may be warranted.

  19. Adapting an empirically supported intervention for a new population and setting: findings and lessons learned from Proyecto Puentes.

    With an increasing emphasis on evidence-based practice, the need for social work researchers and practitioners to adapt empirically supported interventions for new populations and cultures is essential. However, social work suffers from a lack of guidance and detailed examples of intervention adaptations that may not proceed "by the book" and actually falter but recover. Many of these situations result from lack of attention to setting and context even when researchers believe they have full stakeholder buy-in. This article presents process evaluation findings from an intervention adaptation called Proyecto Puentes that allowed for self-correction and successful intervention development.

    Citizen science projects store an enormous amount of information about species distribution, diversity and characteristics. Researchers are now beginning to make use of this rich collection of data. However, access to these databases is not always straightforward. Apart from the largest and international projects, citizen science repositories often lack specific Application Programming Interfaces (APIs) to connect them to the scientific environments. Thus, it is necessary to develop simple routines to allow researchers to take advantage of the information collected by smaller citizen science projects, for instance, programming specific packages to connect them to popular scientific environments (like R). Here, we present rAvis, an R-package to connect R-users with Proyecto AVIS (http://proyectoavis.com), a Spanish citizen science project with more than 82,000 bird observation records. We develop several functions to explore the database, to plot the geographic distribution of the species occurrences, and to generate personal queries to the database about species occurrences (number of individuals, distribution, etc.) and birdwatcher observations (number of species recorded by each collaborator, UTMs visited, etc.). This new R-package will allow scientists to access this database and to exploit the information generated by Spanish birdwatchers over the last 40 years. PMID:24626233

    To report the prevalence of age-related macular degeneration (AMD) in a population-based sample of Hispanic individuals aged 50 years and older. Proyecto VER (Vision and Eye Research) is a population-based study of blindness and visual impairment of Hispanic people in Arizona. Participants underwent complete ophthalmic evaluation, including stereoscopic fundus photography of fields 1, 2, and 4. All photographs for participants aged 50 years and older were graded using the Wisconsin Age-Related Maculopathy Grading system. The following signs were graded: drusen size, drusen type, and the area covered by drusen; pigmentary abnormalities; geographic atrophy; and exudative AMD. Sixty-seven percent (3178) of the original 4774 participants were 50 years of age or older. Of those, 92% (2928) had fundus photographs in at least 1 eye, and 95% (2780) of the photographs were of sufficient quality to grade early and late AMD. The overall prevalence of late AMD was 0.5%. The prevalence increased from 0.1% in the 50- to 59-year age group to 4.3% in the group aged 80 years and older. Likewise, early AMD was strongly associated with age with a prevalence of 20% in the 50- to 59-year age group, increasing to 54% in the group aged 80 years and older. The prevalence of early AMD in Hispanic people was significantly higher than the reported prevalence in the white population. However, the prevalence of late AMD was lower than the estimates for the white population of the United States. Although early macular changes were very common among Hispanic people, the prevalence of late AMD was infrequent. Further work is necessary to understand the underlying reasons for the different patterns of presentation of early and late signs of AMD among racial/ethnic groups and to characterize early AMD based on predictive value for severe disease in different populations.

    Risk factors for type II diabetes and diabetic retinopathy were determined in a population-based study of Mexican-Americans. Proyecto VER (Vision, Evaluation, and Research) is a cross-sectional study in a random sample of the self-described Hispanic populations in Tucson and Nogales, Arizona, age 40 and older. Of 6,659 eligible subjects, 4,774 (72%) participated in the home questionnaire and clinic visit. Diabetes was defined as self-report of a physician diagnosis or hemoglobin A(1c) value of > or = 7.0%. Only type II diabetes was included. Diabetic retinopathy was assessed on stereo fundus photographs of all persons with diabetes. Questions were asked about demographic, personal, socioeconomic, and diabetes related variables. 1023 (21.4%) of the sample had type II diabetes, and 68% were in the low-income group (annual income less than $20,000). Diabetes was associated with Native-American ancestry, higher acculturation, low income, less education, and increasing body mass index after age and gender adjustment. Persons with previously undiscovered diabetes were more likely to have no regular source of care, no insurance, and currently smoke compared with persons with known diabetes. Only low income was related to proliferative retinopathy, once adjusted for other factors (odds ratio [OR] = 3.93, 95%, confidence limitations [CL] = 1.31-11.80). Several socioeconomic and other factors were associated with diabetes, but few were related to diabetic retinopathy. Persons in the low-income group appeared to be at greater risk of diabetes and the ocular complications of diabetes compared with those with more income. Further longitudinal studies in this population are needed to confirm the associations.

    To report the prevalence of blindness and visual impairment and the contribution of uncorrected refractive error to visual loss, in a population-based sample of Mexican Americans aged 40 and older. Proyecto VER is a population-based study of blindness and visual impairment in Mexican Americans in Arizona. Block groups in Tucson and Nogales were randomly selected with probability proportional to the size of the Mexican-American population aged 40 and older. Participants had a complete ophthalmic evaluation, including assessment of presenting and best corrected visual acuity using standardized procedures. Those with presenting visual acuity worse than 20/30 had refraction to determine best corrected vision. A home questionnaire and a clinic examination provided data on education, perception of visual impairment, income, and acculturation. The prevalence of presenting visual acuity worse than 20/40 was 8.2%, with uncorrected refractive error accounting for 73% of the impaired acuity. In multivariate models comparing those who improved two or more lines on the acuity chart with proper refraction with those who had adequate optical correction, uncorrected refractive error showed a strong association with age, less than 13 years of education (odds ratio [OR] 1.6, 95% confidence interval [CI] 1.5-2.0), low acculturation index (OR 1.3, CI 1.1-1.3), lack of insurance coverage (OR 1.4, CI 1.1-1.7), and not having seen an eye-care provider in the past 2 years (OR 2.5, CI 2.1-3.0). Prevalence of best corrected acuity worse than 20/40 increased from 0.3% in those aged 40 to 49 years to 18% in those aged 80 years or more. Visual loss in this Mexican-American population is higher than has been reported in whites and is comparable to that in African Americans. Almost three quarters of those with visual acuity impairment would improve with optical correction. Socioeconomic factors that are probable markers of limited access to health care services were associated with uncorrected

    At the northeast tip of the Yucatan Peninsula - where the Caribbean meets the Gulf - lies the ancient Maya port site of Vista Alegre. The inhabitants of this site, much like the people living nearby today, were forced to contend with the challenging coastal environment of Laguna Holbox. The sediment-rich, low gradient of the north coast presents a contrasting landscape compared to the Caribbean coast, where water resources are of much larger magnitude and evident in the extensive systems of cenotes (sinkholes) and underground rivers that supported pre-Columbian sites along this eastern rocky sediment-poor coastline. For past inhabitants the north coast was a mosaic of low-lying, non-arable zones where access to potable water was a challenge for inhabitants well into the 20th century. By bringing together scholars from the fields of archaeology, coastal ecology, geoarchaeology, and hydrogeology, the Proyecto Costa Escondida is focusing on the dynamic relationship between the Maya and their coastal landscape over the past 3000 years. To date we have collected 12 manual push-cores from the shallow waters surrounding Vista Alegre, which have been analyzed at 1 cm resolution using standard methods for Loss on Ignition (LOI), δ18Ocarb and δ13Ccarb of bulk carbonate, granulometry, micropalentology, and AMS radiocarbon dating. In addition to have baseline comparative data, we have conducted near-shore and terrestrial coastal ecological surveys along with the mapping of coastal water salinity and temperatures in the dry and wet seasons. Overall, the chemical proxies, lithology, and paleosalinity model reconstructed to date reveal four onlapping parasequences representing an overall transgression of the coastline with strong seasonality of water chemistry that has been changing under the control of rising sea levels over the past 3000 years. The sedimentation rate and timing of the transition to marine is in reasonable agreement with local sea level curves meaning that the

    Health care discrimination is increasingly considered a significant barrier to accessing health services among minority populations, including Latinos. However, little is known about the role of immigration status. The purpose of this study was to examine the association between immigration status and perceived health care discrimination among Latinos living in rural areas. Interviews were conducted among 349 young-adult Latinos (ages 18 to 25) living in rural Oregon, as part of Proyecto de Salud para Latinos. Over a third of participants experienced health care discrimination (39.5 %). Discrimination was higher among foreign-born (44.9 %) rather than US-born Latinos (31.9 %). Multivariate results showed that foreign-born Latinos were significantly more likely to experience health care discrimination, even after controlling for other relevant factors (OR = 2.10, 95 % CI 1.16-3.82). This study provides evidence that health care discrimination is prevalent among young-adult Latinos living in rural areas, particularly the foreign-born. Effective approaches towards reducing discrimination in health care settings should take into consideration the need to reform our broken immigration system.

    Urban food swamps are typically situated in low-income, minority communities and contribute to overweight and obesity. Changing the food landscape in low income and underserved communities is one strategy to combat the negative health consequences associated with the lack of access to healthy food resources and an abundance of unhealthy food venues. In this paper, we describe Proyecto MercadoFRESCO (Fresh Market Project), a corner store intervention project in East Los Angeles and Boyle Heights in California that used a multi-level approach with a broad range of community, business, and academic partners. These are two neighboring, predominantly Latino communities that have high rates of overweight and obesity. Located in these two communities are approximately 150 corner stores. The project used a community-engaged approach to select, recruit, and convert four corner stores, so that they could become healthy community assets in order to improve residents' access to and awareness of fresh and affordable fruits and vegetables in their immediate neighborhoods. We describe the study framework for the multi-level intervention, which includes having multiple stakeholders, expertise in corner store operations, community and youth engagement strategies, and social marketing campaigns. We also describe the evaluation and survey methodology to determine community and patron impact of the intervention. This paper provides a framework useful to a variety of public health stakeholders for implementing a community-engaged corner store conversion, particularly in an urban food swamp.

    Urban food swamps are typically situated in low-income, minority communities and contribute to overweight and obesity. Changing the food landscape in low income and underserved communities is one strategy to combat the negative health consequences associated with the lack of access to healthy food resources and an abundance of unhealthy food venues. In this paper, we describe Proyecto MercadoFRESCO (Fresh Market Project), a corner store intervention project in East Los Angeles and Boyle Heights in California that used a multi-level approach with a broad range of community, business, and academic partners. These are two neighboring, predominantly Latino communities that have high rates of overweight and obesity. Located in these two communities are approximately 150 corner stores. The project used a community-engaged approach to select, recruit, and convert four corner stores, so that they could become healthy community assets in order to improve residents’ access to and awareness of fresh and affordable fruits and vegetables in their immediate neighborhoods. We describe the study framework for the multi-level intervention, which includes having multiple stakeholders, expertise in corner store operations, community and youth engagement strategies, and social marketing campaigns. We also describe the evaluation and survey methodology to determine community and patron impact of the intervention. This paper provides a framework useful to a variety of public health stakeholders for implementing a community-engaged corner store conversion, particularly in an urban food swamp. PMID:25209600

    We used qualitative, quantitative and observational methods to assess the feasibility, acceptability, and potential efficacy of Proyecto Orgullo (PO), a pilot community mobilisation intervention to decrease sexual risk, promote health-seeking behaviours, and facilitate personal and community empowerment among gay men (GM) and transgender women (TW) in Peru. PO was adapted from Mpowerment and Hermanos de Luna y Sol, two US interventions. PO included six interrelated core elements: 1) Self-reflection Small Group sessions; 2) Supporting peers in HIV prevention; 3) Mobilisation Activities addressing HIV, GM/TW issues, and community empowerment; 4) A Core Group (staff + GM/TW volunteers) designing/implementing those activities; 5) A Project Space; 6) Publicity. PO included specific components for TW, but promoted that GM/TW, who historically have not worked well together, collaborate for a common goal. We found that PO was embraced by GM/TW. PO positively influenced GM/TW's HIV prevention beliefs, self-efficacy, and behaviours; provided social support and created community; facilitated individual and community empowerment; achieved that GM/TW collaborate; and established a functional Community Centre for socializing/conducting mobilisation activities. Community mobilisation strategies, lacking from HIV prevention efforts in Peru but considered key to HIV prevention, can help improve health-seeking behaviours and consolidate social norms supporting preventive behaviours among GM/TW.

    Musso, S.

    ?`Qué es la Astronomía para Ciegos?. El trabajo es una adaptación en base a la escala de magnitudes de Hipparco que cambia el concepto de luz por una adaptación sonora, donde las estrellas de magnitud 6 se escuchan en 10 dB, más o menos lo que consideramos el umbral de la audición humana. Quienes no escuchan muy bien no pueden escuchar las magnitudes 6, de la misma manera que muchos de nosotros, que no poseemos una visión perfecta, no podemos observar esas mismas estrellas en el cielo (más allá de la polución). A los astros de magnitud 5 vamos a relacionarlos a un sonido en 20 dB. Y así sucesivamente. También los colores estarán representados en una convención de graves a agudos y lo mismo algunas características del cielo. Por ejemplo, la Vía Láctea se mostrará como un ``ruido", como bien nos lo hicieron ver nuestros futuros destinatarios. En Mar del Plata nos encontramos ya trabajando en un proyecto que tiene como objetivo final la construcción del Primer Planetario Acústico del Mundo, una herramienta para la enseñanza de la astronomía, un espacio para la lucha contra la discriminación del discapacitado y una posibilidad de ``ver el cielo de un modo diferente".

    The planets Earth and Mars reached in August 2003 the most approximation in the last 58,000 years. In order to that we carried out a transversal study of red planet, joining the knowledges from several subjects of second school year of unified basic cycle (eighth basic general education) at I.P.E.M. No 249 "Nicolás Copérnico" (a public secondary institution from Córdoba, Argentine). In this study, activities in accordance with current contents has been proposed by common consents of each teacher. Besides, students visited Córdoba Astronomical Observatory in order to search informations and received a multimedia exposition about of astronomical event and a performance of the "Carl Sagan" Moveable Planetary. Finally, each student carried out practical works and wrote an integrative report, which one has been evaluated and exposed at ExpoIPEM 2003, an annual exhibition of several specialities that Institution offers in its specialization cycle (10-12 grade), where the annual students' activities are exhibited too (workshops, school projects, etc.).

    Los modelos de eensenanza y aprendizaje constructivistas conceptualizan el aprendizaje como un proceso activo. El modelo de Aprendizaje Basado en Proyectos (ABPr) se distingue por una serie de componentes, entre los cuales se destaca el aspecto colaborativo y cooperativo como un reto al momento de su implantacion. Son pocas las investigaciones que se concentran en este aspecto del modelo. En este estudio, se analizaron las diversas interacciones que surgen durante la implantacion de una unidad curricular sobre el tema de Geologia de Puerto Rico, la cual se diseno con el modelo ABPr cuyo enfoque es orientacion a proyectos. Particularmente, se examinaron las interacciones sociales que surgen entre los pares y entre pares y docente durante el proceso de planificacion y desarrollo de los productos finales, al igual que las interacciones entre los estudiantes y el material didactico en estas etapas del modelo. La investigacion es de tipo cualitativo e incorpora como diseno el estudio de caso. Las diversas interacciones constituyen la unidad de analisis. En el estudio participaron 19 estudiantes de 9no grado, a quienes se organizaron en 5 grupos colaborativos por temas de interes (Pangea, Placas tectonicas, Volcanes, Tsunamis y Terremotos). Las tecnicas que se utilizaron para recopilar los datos fueron: observaciones participativas, grupos focales y analisis de documentos (cuadernos reflexivos y respuestas de los estudiantes a la pregunta central del proyecto). Para el analisis de los datos se aplico la teoria de actividad (CHAT) que concentra la unidad de analisis en la actividad humana en un contexto particular. Los resultados del estudio senalan que las interacciones entre pares, entre pares y docente, asi como entre estudiantes y material didactico son fundamentales en el proceso de aprendizaje. Una mayor interaccion entre pares durante las etapas de planificar y desarrollar los productos finales de la unidad, promueve una mejor comprension de los conceptos de la

    The CARMA Large Area Star-formation Survey (CLASSy) is a CARMA Key Project which is mapping 5 fields covering about 150 square-arcminutes each in the Perseus (3 fields) and Serpens (2 fields) Molecular Clouds. CLASSy consists of 3 mm interferometric observations with angular resolution, being sensitive to spatial scales between 1000 AU to 3 pc. Particularly, the analysis of the NH(1-0) molecular emission from the filamentary structures found in these star--forming regions constrain theoretical models explaining their origin and evolution. Gas kinematics observations show velocity gradients that suggest possible explanations on how filaments are formed. In addition, from the analysis of the kinematics we carried out a pioneer study of the turbulence in these clouds.

    Pterygium is a common corneal eye condition that can be disfiguring and may require surgery to avoid loss of vision. There are no population-based data on the prevalence or on risk factors among Latinos. A population-based sample of 4774 self-reported Latinos age > or = 40 years from randomly selected block groups in Nogales and Tucson, Arizona, USA, were enrolled in the study. Questionnaires were conducted in the home on risk factors. A clinical examination by an experienced ophthalmologist was carried out, and the presence of pterygium was diagnosed at the examination. The prevalence of pterygium was high (overall 16%). Men had a higher rate than women (23.7% versus 11.5%, respectively). Low income and low educational status were associated with higher odds of pterygium. Current smoking, and smoking dose, was protective for pterygium; this finding has now been reported from several studies. Pterygium rates were high in this population of Latinos. Socioeconomic status markers for increased exposure to sunlight suggest this may be the target of simple interventions to reduce the risk of pterygium in this ethnic population.

    Hypocaloric peripheral parenteral nutrition (HPPN) appears to be indicated in patients with moderate malnutrition subjected to a short period of fasting following surgery. Our objective is to determine whether or not the intake of hypocaloric parenteral solutions containing aminoacid is useful in postsurgical patients, by means of a study of different nutritional evaluation parameters. A study was performed on 35 postsurgical patients who fulfilled at least 2 of the following criteria indicating malnutrition: 1) albumin levels less than 3 g/dl; 2) prealbumin levels less than 21 mg/; 3) body weight less than 95% of ideal weight. The patients were divided into 3 groups: Group I consisted of 15 patients treated with conventional fluid therapy, Group II consisted of 10 patients treated with nutritional support based on glucose and aminoacid and Group III was comprised of 10 patients also treated with a nutritional therapy based on glycerol and aminoacid. The most significant data included a rapid recovery of short term proteins (prealbumin and retinol-binding protein) and a less negative nitrogen balance 5 days afterwards in both the glucose and glycerol groups, both of which were statistically significant. With regard to complications studied, there was a greater incidence of suture dehiscence in the control group than in the groups under treatment (13.3% compared to 50%). Our conclusion is that HPPN is a valid nutritional support measure in postsurgical patients in certain clinical situations and circumstances, although further controlled, randomized studies should be considered, during both the pre and post operative periods of these patients in order to clearly indicate how and when nutritional therapy should be applied.

    To determine the prevalence of refractive error (RE), the proportion of those with uncorrected RE, and factors associated with uncorrected RE in Latino adults. Population-based, cross-sectional study. A random sample of 4509 Latinos aged ≥40 years from Arizona with both ophthalmic evaluation and questionnaire. A case of RE was defined as a subject wearing prescription glasses for distance vision whose presenting visual acuity (PVA) was ≥20/25, or a subject with PVA <20/25 in at least 1 eye who improved ≥2 lines after subjective refraction and whose refractive correction met these cutoffs: sphere < -0.5 diopters (D) or >1.0 D or cylinder ≥ +1.0 D. Among those with RE, those who on refraction achieved ≥2 line improvement in at least 1 eye (definition 1) or in both eyes (definition 2) were classified as uncorrected RE. A questionnaire on access to care, acculturation, and socioeconomic variables was used. Prevalence of RE and proportion of uncorrected RE. The prevalence of RE was 64% in at least 1 eye and 51% in both eyes. Of participants with RE in at least 1 eye, 35% have uncorrected RE. Of those with RE in both eyes, 19% have uncorrected RE. Compared with participants with corrected RE, those with uncorrected RE in at least 1 eye were more likely to have lower levels of acculturation (odds ratio [OR] 1.2; 95% confidence interval [CI], 1.1-1.4 per unit decrease) and education (OR 1.6 for ≤6 years vs. >12 years; 95% CI, 1.2-2.2). Uncorrected RE was also associated with not having insurance (OR 1.4; 95% CI, 1.1-1.6), with a low family income (OR 1.4; 95% CI, 1.1-1.7 for <$20,000/year), and with time since last health care visit (OR 1.4; 95% CI, 1.1-1.7 for >1 year vs. <6 months). In our sample of Latinos, the proportion of uncorrected RE is high and suggests that one third of those with RE may benefit from new glasses. Indices of marginalization are associated with uncorrected RE and could be targeted for future interventions. Copyright © 2011 American Academy of Ophthalmology. Published by Elsevier Inc.

    Purpose To determine the prevalence of refractive error (RE), and the proportion of those with uncorrected refractive error and factors associated with uncorrected RE in Latino adults. Design Population-based, cross-sectional study. Participants A random sample of 4,509 Latinos ≥40 years from Tucson and Nogales, Arizona with both ophthalmic evaluation and questionnaire were included in these analyses. Methods A case of RE was defined as subject wearing prescription glasses for distance vision whose presenting visual acuity (PVA) was 20/25 or better, or subject with PVA worse than 20/25 in at least one eye who improved ≥2 lines after subjective refraction and whose refractive correction met these cutoffs: sphere <−0.5 diopters (D) or >1.0D or cylinder ≥+1.0D. Among those with RE, those who on refraction achieved ≥2 line improvement in at least one eye (definition 1) or in both eyes (definition 2) were classified as uncorrected RE. A questionnaire on access to care, acculturation, perceived barriers, income, and education was asked. Main Outcome Measures Prevalence of RE and proportion of uncorrected RE Results The overall prevalence of RE in at least one eye was 64%, and in both eyes was 51%. Of participants with RE in at least one eye, 35% have uncorrected RE. Of those with RE in both eyes, 19% have uncorrected RE. As compared to those with corrected RE, those with uncorrected RE in at least one eye were more likely to have lower levels of acculturation (Odds Ratio [OR]=1.2; 95% Confidence Interval [CI]: 1.1–1.4 per unit decrease) and education (OR=1.6 for ≤6 years vs. >12 years; 95% CI: 1.2–2.2). Uncorrected RE was also significantly associated with not having insurance (OR=1.4; 95% CI: 1.1–1.6), a low family income (OR=1.4; 95% CI: 1.1–1.7 < $20,000/year), and time since last health care visit (OR=1.4; 95% CI: 1.1–1.7 for >1 year vs. <6 months). Conclusions In our sample of Latinos the overall proportion of uncorrected RE is high, and suggests that one third of those with RE may benefit from a new pair of glasses. Indices of marginalization are associated with uncorrected RE, and could be targeted for future interventions. PMID:21146226

    Introducción Estudios internacionales demuestran que existe un patrón diferenciado de salud y una disparidad en la atención sanitaria entre personas con discapacidad intelectual (DI) y población general. Objetivo Obtener datos sobre el estado de salud de las personas con DI y compararlos con datos de población general. Pacientes y métodos Se utilizó el conjunto de indicadores de salud P15 en una muestra de 111 sujetos con DI. Los datos de salud encontrados se compararon según el tipo de residencia de los sujetos y se utilizó la Encuesta Nacional de Salud 2006 para comparar estos datos con los de la población general. Resultados La muestra con DI presentó 25 veces más casos de epilepsia y el doble de obesidad. Un 20% presentó dolor bucal, y existió una alta presencia de problemas sensoriales, de movilidad y psicosis. Sin embargo, encontramos una baja presencia de patologías como la diabetes, la hipertensión, la osteoartritis y la osteoporosis. También presentaron una menor participación en programas de prevención y promoción de la salud, un mayor número de ingresos hospitalarios y un uso menor de los servicios de urgencia. Conclusiones El patrón de salud de las personas con DI difiere del de la población general, y éstas realizan un uso distinto de los servicios sanitarios. Es importante el desarrollo de programas de promoción de salud y de formación profesional específicamente diseñados para la atención de personas con DI, así como la implementación de encuestas de salud que incluyan datos sobre esta población.

    The management of ductal intraepithelial neoplasia (DIN) has substantially changed over the past 30 years, as its incidence has increased (from 2-3% to more than 20%), mainly due to the widespread use of mammography screening. This article describes not only the more widespread theoretical concepts on DIN but also the differences in the practical applications of the theory between different countries, different oncology specialists, and different cancer centers. Papers related to the international multicentre-randomized trials and retrospective studies were analyzed. We include articles and papers published between 1993 and 2010 related to patients with DIN, and abstracts and reports from MEDLINE and other sources were indentified. The standard of care for DIN consists of (a) breast conservative surgery (mastectomy is still indicated in large lesions--masses or microcalcifications--in about 30% of cases); (b) radiotherapy (RT) after conservative surgery, and (c) medical treatment in estrogen receptors-positive patients. However, most studies have shown significant differences between theory and practical application. Moreover, there are differences regarding (a) the indications of sentinel lymph node biopsy, (b) the definition and identification of low-risk DIN subgroups that can avoid RT and tamoxifen, and (c) the research into new alternative drugs in adjuvant medical therapy. A general agreement on the best management of DIN does not exist as yet. New large trials are needed in order to define the best management of DIN patients which is (in most respects) still complex and controversial.

    Objetivo: contribuir a la armonización europea de la biovigilancia en humanos (proyecto DEMOCOPHES) demostrando la utilidad de los estudios de biovigilancia para valorar la influencia de la dieta y los estilos de vida como vía de exposición a contaminantes ambientales. Métodos: se adaptó el protocolo europeo a las necesidades nacionales, siguiendo los controles de calidad definidos en él y sin comprometer la obtención de datos comparables entre los países participantes. Resultados: la adaptación nacional del protocolo europeo no presentó grandes dificultades y, salvo mínimas modificaciones, se respetó el diseño original del estudio. Participaron 134 parejas madre-hijo, seleccionados en un colegio de Añover de Tajo (Toledo) y tres colegios de Madrid. Los voluntarios donaron una muestra de pelo y de orina y contestaron a las preguntas del cuestionario epidemiológico. Se observaron diferencias significativas en la participación de los voluntarios en las dos localizaciones de muestreo. Discusión: la estandarización de todas las etapas de un estudio de biovigilancia en humanos es esencial para su desarrollo armonizado a escala internacional. Los resultados obtenidos han contribuido a la obtención de datos sobre exposición ambiental, por primera vez comparables en 17 países europeos, y han permitido observar diferencias relacionadas con la dieta y los hábitos de vida. Las experiencias y el material de trabajo desarrollado para el estudio piloto serán aplicables al diseño e implementación de futuros estudios de HBM.

    To assess the psychometric properties of the NEI-VFQ-25 in a population-based study of older Hispanic persons living in the United States, explore other demographic factors that affect participant response, and observe the comparability of the Spanish and English versions of the instrument. A sample of randomly selected block groups in Tucson and Nogales, Arizona, were selected for study. Participants were interviewed at home; a majority of the interviews were conducted in Spanish. The home interview included questions from the NEI-VFQ-25 and HHANES: Presenting acuity was done using ETDRS methodology, followed by a standardized eye examination by an ophthalmologist. The authors analyzed the internal consistency of the NEI-VFQ-25 responses using Cronbach's alpha coefficient and the construct validity by assessing the relationship between presenting acuity and scale scores, adjusting for age and gender. A second model was also explored to determine whether other demographic variables affected scale scores; differences in reporting between the Spanish and English versions was observed in this model, used in a subset of the population that minimized interviewer effect. Of the 4774 participants in the study, 99.7% had completed questionnaires, not completed by proxy. The highest nonresponse rate occurred in the Driving scale, with 25% of participants not driving for reasons other than problems with vision. Internal consistency was high, with Cronbach alpha ranging between 0.65 and 0.86 for scales with multiple items. Adjusting for age and gender, those with presenting acuity worse than 20/40 scored significantly lower than those with presenting acuity 20/40 or better, for all scales. The demographic variables with the most consistent association across the NEI-VFQ-25 scales were presenting acuity, income, and gender. No significant differences in reporting were found between the Spanish and English versions of the questionnaire in the subset of the population. In this study of Hispanic people age 40 years or older, the NEI-VFQ-25 was sensitive to presenting acuity and other demographic variables, such as age, gender, and income. The findings from this psychometric analysis provide evidence of the reliability and validity of some of the scales in the 25-item NEI-VFQ when used among people with a range of visual acuity level, providing other explanatory variables are also considered.

    The purpose of this study was to examine effect modifiers of the relationship between family history of diabetes, a proxy for genetic predisposition, and the metabolic syndrome. Subjects were a cross-sectional sample of 205 Mexican-Americans patients of the San Ysidro Health Center in San Diego County. Self-reported parental history of diabetes was examined as a risk factor for individual metabolic syndrome traits (hyperglycemia, hypertension, abdominal obesity, hypertriglyceridemia and low HDL-cholesterol) and a composite phenotype, defined both by standard modified National Cholesterol Education Program- Adult Treatment Panel III (NCEP-ATPIII) criteria and using principal components analysis, in age and sex-adjusted multiple logistic and linear regression models. Family history of diabetes was most strongly associated with individual traits of hyperglycemia (P = .0002) and low HDL-C (P = .001) and conferred a significant increased odds of metabolic syndrome defined by both NCEP-ATPIII criteria (odds ratio 3.57, 95% confidence interval 1.82, 7.01; P = .0002) and by principal components analysis (P = 0.003). Moreover, the family history association with metabolic syndrome was modified by number of years living in the United States (interaction P = .04). This same effect was not seen for diabetes (P = .19). The results of our study support a common etiology for at least some components of the metabolic syndrome, especially hyperglycemia and low HDL-cholesterol, the basis of which may be genetic. Moreover, the effect of genes on these traits may be modified by longer duration in the United States, supporting the concept of gene-environment interaction in the development of the metabolic syndrome.

  4. The prevalence of glaucoma in a population-based study of Hispanic subjects: Proyecto VER.

    To determine the prevalence of glaucoma in a population-based sample of Hispanic adults older than 40 years. Using 1990 census data for Arizona, groups of persons living in sections of the city in Nogales and Tucson were randomly selected with a probability proportional to the Hispanic population older than 40 years. We tried to recruit all eligible adults in homes with 1 self-described Hispanic adult. Detailed ocular examinations at a local clinic included visual acuity testing, applanation tonometry, gonioscopy, an optic disc evaluation, and a threshold visual field test. Open-angle glaucoma (OAG) was defined using a proposed international system for prevalence surveys, including threshold visual field defect and optic disc damage. Angle-closure glaucoma was defined as bilateral appositional angle closure, combined with optic nerve damage (judged by field and disc as for OAG). Examinations were conducted in 72% (4774/6658) of eligible persons, with a 1.97% prevalence (95% confidence interval, 1.58%-2.36%) of OAG (94 persons). The age-specific OAG prevalence increased nonlinearly from 0.50% in those aged 41 to 49 years to 12.63% in those 80 years and older. Angle-closure glaucoma was detected in 5 persons (0.10%). Sex, blood pressure, and cigarette smoking were not significant OAG risk factors. Only 36 (38%) of the 94 persons with OAG were aware of their OAG before the study. Screening results with an intraocular pressure higher than 22 mm Hg (in the eye with a higher pressure) would miss 80% of the OAG cases. The prevalence of OAG in Hispanic persons was intermediate between reported values for white and black persons. The prevalence increased more quickly with increasing age than in other ethnic groups. Glaucoma was the leading cause of bilateral blindness.

    Candidemia is one of the most frequent opportunistic mycoses worldwide. Limited epidemiological studies in Latin America indicate that incidence rates are higher in this region than in the Northern Hemisphere. Diagnosis is often made late in the infection, affecting the initiation of antifungal therapy. A more scientific approach, based on specific parameters, for diagnosis and management of candidemia in Latin America is warranted. 'Recommendations for the diagnosis and management of candidemia' are a series of manuscripts that have been developed by members of the Latin America Invasive Mycosis Network. They aim to provide a set of best-evidence recommendations for the diagnosis and management of candidemia. This publication, 'Recommendations for the diagnosis of candidemia in Latin America', was written to provide guidance to healthcare professionals on the diagnosis of candidemia, as well as on the usefulness and application of susceptibility testing in patients who have a confirmed diagnosis of candidemia. Computerized searches of existing literature were performed by PubMed. The data were extensively reviewed and analyzed by members of the group. The group also met on two occasions to pose questions, discuss conflicting views, and deliberate on a series of management recommendations. 'Recommendations for the diagnosis of candidemia in Latin America' includes diagnostic methods used to detect candidemia, Candida species identification, and susceptibility testing. The availability of methods, their costs and treatment settings are considered. This manuscript is the first of this series that deals with diagnosis and treatment of invasive candidiasis. Other publications in this series include: 'Recommendations for the management of candidemia in adults in Latin America', 'Recommendations for the management of candidemia in children in Latin America', and 'Recommendations for the management of candidemia in neonates in Latin America'.

    2008-06-01

    Balancing power among academic and community partners, addressing community-identified needs, and strengthening community capacity are ethical values unique to community-based participatory research (CBPR). Negotiation of these values in one CBPR environmental justice project was evaluated to advance the environmental and occupational health of a Hispanic agricultural community in central Washington State. Data were collected through document review and participant observation. Applied conversation and discourse analysis were used to interpret the data. Within the organization, farmworkers primarily served an advisory role. Facilitation style influenced how participants negotiated environmental justice. Research goals were advanced in the project, but no direct actions were taken to improve farmworker health. Implementing CBPR's ethical values requires a willingness to confront institutional and interpersonal challenges, and offers a vision of research that builds knowledge and strengthens communities.

    Latina intimate partner violence (IPV) survivors often face great barriers to depression care. We sought to use a community-based participatory research (CBPR) approach to create and evaluate a community-based depression care program for Latina IPV survivors. We created a multifaceted, culturally tailored intervention, based on principles of chronic illness management. A promotora provided case management services and led 12 weekly group sessions. Participants completed surveys at baseline and 6 months and participated in open-ended exit interviews. Ten Spanish-speaking Latina women participated in the intervention. The program had excellent attendance, with 100% of women attending at least 10 group sessions, and high satisfaction. We found a large decrease in depression severity (Patient Health Questionnaire [PHQ]-9, 17.3-7.2; p = .001), as well as improvements in depression self-efficacy, self-esteem, and stress. This study offers promising preliminary data to support the use of community-based approaches to reducing depression disparities in Latina IPV survivors.

    The proportion of women entering pregnancy overweight or obese has been rising and, in turn, is associated with adverse maternal and fetal outcomes. Gestational weight gain (GWG) exceeding Institute of Medicine (IOM) guidelines further increases health risks and has been independently associated with postpartum weight retention. Hispanic women are disproportionately affected by overweight and obesity, but have had limited access to interventions that promote healthy lifestyles due to cultural, socioeconomic, and language barriers. Therefore, the overall goal of this randomized controlled trial is to test the efficacy of a culturally and linguistically modified, individually-tailored lifestyle intervention to reduce excess GWG, increase postpartum weight loss, and improve maternal metabolic status among overweight/obese Hispanic women. Overweight/obese Hispanic women are recruited in early pregnancy and randomly assigned to a Lifestyle Intervention (n = 150) or a Comparison Health and Wellness (control) intervention (n = 150). Multimodal contacts (i.e., in-person, telephone counseling, and mailed print-based materials) are used to deliver the intervention from early pregnancy (12 weeks gestation) to 6 months postpartum, with follow-up to 1 year postpartum. Targets of the intervention are to achieve IOM Guidelines for GWG and postpartum weight loss; American Congress of Obstetrician and Gynecologist guidelines for physical activity; and American Diabetes Association guidelines for diet. The intervention draws from Social Cognitive Theory and the Transtheoretical Model and includes strategies to address the specific social, cultural, and economic challenges faced by low-income Hispanic women. Assessments are conducted at baseline (~10 weeks gestation), mid pregnancy (24-28 weeks gestation), late pregnancy (32-34 weeks gestation) and postpartum at 6-weeks, 6-months, and 12-months by bicultural and bilingual personnel blinded to the intervention arm. Efficacy is assessed via GWG, postpartum weight loss, and biomarkers of glycemic control, insulin resistance, and cardiovascular disease risk factors. Changes in physical activity and diet are measured via 7-day accelerometer data and 24-h dietary recalls at each assessment time period. Hispanic women are the fastest growing minority group in the U.S. and are disproportionately affected by overweight and obesity. This randomised trial uses a high-reach, low-cost strategy that can readily be translated into clinical practice in underserved and minority populations. NCT01868230 May 29, 2013.

    To report the technique of 3D-conformal radiation therapy (3D-CRT) currently used at our Institute for the treatment of prostate cancer with a curative intent. A critical review of the technical aspects of the technique is provided. Between December 1995 and October 2000, 334 patients with biopsy-proven adenocarcinoma of the prostate were treated with 3D-CRT. All patients were treated in a prone position with 15 MV X-ray beams and a 6-field technique for all but 20 patients, who were treated with a 3-field technique. Patients were simulated with the rectum and bladder empty. To ensure reproducible positioning, custom-made polyurethane foam or thermoplastic casts were produced for each patient. Subsequently, consecutive CT scan slices were obtained. The clinical target volume and critical organs (rectum and bladder) were identified on each CT slice. The beam's eye view technique was used to spatially display these structures, and the treatment portals were manually shaped based on the images obtained. The beam apertures were initially realized by conventional Cerrobend blocks (48 patients), which were replaced in October 1997 by a computer-driven multi-leaf collimator. The total target dose prescribed at the ICRU point is 76 Gy, delivered in 38 fractions and 54 days. The seminal vesicles are excluded at 70 Gy. Dose-volume histograms were obtained for all patients. If more than 30% of the bladder and/or more than 20% of the rectum receive >95% of the prescribed total dose, the treatment plan is judged as unsatisfactory and is adjusted. The dose-volume histogram can be improved by changing the beam's arrangement and/or weights or by introducing or modifying the wedge filters. 3D-CRT in prostate cancer patients is a highly sophisticated and time-consuming method of dose delivery. Important technical issues remain to be clarified.

    To describe the relationship of visual acuity impairment and eye disease on vision-related quality of life, as measured by the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25), in a cross-sectional, population-based study of older Hispanic persons living in Arizona. A random sample of block groups with Hispanic residents in Nogales and Tucson, Arizona, were selected for study. Participants were interviewed at home with a questionnaire that included the NEI-VFQ-25, an instrument measuring vision-related quality of life. Acuity was obtained with Early Treatment Diabetic Retinopathy Study (ETDRS) charts and standard protocol. Cataract was determined by clinical examination, diabetic retinopathy was diagnosed on stereo fundus photographs, and glaucoma was diagnosed on the basis of clinical examination and visual field results. Analyses were done to determine the degree of association between subscale scores and acuity in the better-seeing eye, monocular visual impairment, and specific eye diseases, with adjustment for acuity. Of the 4774 participants in the study, 99.7% had completed questionnaires that were not completed by proxy. Participants with visual impairment had associated decrements in scores on all subscales, with a decrease in presenting acuity associated with a worse score (P < 0.05), after adjustment for demographic variables. Monocular impairment was also associated with lower scores in several subscales. In those with cataract, low acuity explained most of the low scores, but those with glaucoma or diabetic retinopathy had low scores independent of acuity. In this study of Mexican-American persons aged 40 or more, monocular impairment and better-eye acuity was associated with a decrease in most domains representing quality of life. Subjects with uncorrected refractive error, cataract, diabetic retinopathy, and glaucoma had associated decrements in quality of life, many not explained by loss of acuity. Further work on the specific measures of vision associated with reported decreases in quality of life, such as visual field or contrast sensitivity, is warranted.

    Latinos are the largest racial and ethnic minority group in the United States and bear a disproportionate burden of obesity related chronic disease. Despite national efforts to improve dietary habits and prevent obesity among Latinos, obesity rates remain high. The objective of this study is to explore the relationship between self-rated dietary quality and dietary behavior among Latinos and how this may vary by socio-demographics to help inform future public health efforts aiming to improve eating habits and obesity rates. Cross-sectional study using a series of chi-square tests, the non-parametric Wilcoxon-Mann-Whitney test and logistic regression to explore self-rated eating habits. Two urban, low-income, predominantly Latino neighborhoods in Los Angeles County. 1000 adults who self-identified as their household's primary food purchaser and preparer were interviewed from 2012 to 2013. Households were randomly selected based on their proximity to corner stores participating in a project to improve the food environment. Most respondents (59%) report "good" eating habits. Significant associations between "good" eating habits and overall health, fruit and vegetable consumption were observed (p < 0.001). Despite these promising findings, we also find high levels of regular soda and energy-dense food consumption. This study revealed a general understanding that healthy dietary habits are associated with fruit and vegetable consumption among Latinos in two urban neighborhoods. However, there is a need for more targeted health promotion and nutrition education efforts on the risks associated with soda and energy-dense food consumption to help improve dietary habits and obesity levels in low-income Latino communities.

    Recurrent exacerbations are common in COPD patients. Limited information exists regarding exacerbation frequency in COPD patients from epidemiologic studies. We examined the frequency of self-reported exacerbations and the factors influencing exacerbation frequency among COPD patients in a population-based study conducted in Latin America. We used a post-bronchodilator FEV(1)/FVC ratio of < 0.70 to define COPD. Exacerbation was self-reported and defined by symptoms (deterioration of breathing symptoms that affected usual daily activities or caused missed work). Spirometry was performed in 5,314 subjects. There were 759 subjects with airflow limitation; of these, 18.2% reported ever having had an exacerbation, 7.9% reported having an exacerbation, and 6.2% reported having an exacerbation requiring at least a doctor visit within the past year. The proportion of individuals with an exacerbation significantly increased by Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages, from 4.2% in stage 1 to 28.9% in stages 3 and 4. The self-reported exacerbation rate was 0.58 exacerbations per year. The rate of exacerbations requiring at least a doctor visit and length of stay in hospital due to exacerbations also increased as COPD severity progressed. The factors associated with having an exacerbation in the past year were dyspnea, prior asthma diagnosis, receiving any respiratory therapy, and disease severity of GOLD stages 3 and 4. The proportion of individuals with airflow limitation and self-reported exacerbation increases as the disease severity progresses. Dyspnea, prior asthma diagnosis, receiving any respiratory therapy, and more severe obstruction were significantly associated with having an exacerbation in the past year.

    2003-11-01

    This thesis is concerned with the acoustic analysis of ecclesiastical spaces, and the subsequent implementation of acoustic design methodology in architectural renovations. One begins with an adequate architectural design of specific elements (shape, materials, and textures), with the intention of elimination of acoustic deficiencies that are common in such spaces. These are those deficiencies that impair good speech intelligibility and good musical audibility. The investigation is limited to churches in the province of Cordoba and to churches built after the reconquest of Spain (1236) and up until the 18th century. Selected churches are those that have undergone architectural renovations to adapt them to new uses or to make them more suitable for liturgical use. The thesis attempts to summarize the acoustic analyses and the acoustical solutions that have been implemented. The results are presented in a manner that should be useful for the adoption of a model for the functional renovation of ecclesiastical spaces. Such would allow those involved in architectural projects to specify the nature of the sound, even though somewhat intangible, within the ecclesiastical space.

    Although there has been an improved management of invasive candidiasis in the last decade, controversial issues still remain, especially in the diagnostic and therapeutic approaches. We sought to identify the core clinical knowledge and to achieve high level agreement recommendations required to care for critically ill adult patients with invasive candidiasis. A prospective Spanish survey reaching consensus by the DELPHI technique was made. It was anonymously conducted by electronic mail in a first term to 25 national multidisciplinary experts in invasive fungal infections from five national scientific societies, including intensivists, anesthesiologists, microbiologists, pharmacologists and infectious diseases specialists, who answered to 47 questions prepared by a coordination group after a strict review of the literature in the last five years. The educational objectives spanned five categories, including epidemiology, diagnostic tools, prediction rules, and treatment and de-escalation approaches. The level of agreement achieved among the panel experts in each item should exceed 75% to be selected. In a second term, after extracting recommendations from the selected items, a face to face meeting was performed where more than 80 specialists in a second round were invited to validate the preselected recommendations. In the first term, 20 recommendations were preselected (Epidemiology 4, Scores 3, Diagnostic tools 4, Treatment 6 and De-escalation approaches 3). After the second round, the following 12 were validated: (1) Epidemiology (2 recommendations): think about candidiasis in your Intensive Care Unit (ICU) and do not forget that non-Candida albicans-Candida species also exist. (2) Diagnostic tools (4 recommendations): blood cultures should be performed under suspicion every 2-3 days and, if positive, every 3 days until obtaining the first negative result. Obtain sterile fluid and tissue, if possible (direct examination of the sample is important). Use non-culture based methods as microbiological tools, whenever possible. Determination of antifungal susceptibility is mandatory. (3) Scores (1 recommendation): as screening tool, use the Candida Score and determine multicolonization in high risk patients. (4) Treatment (4 recommendations): start early. Choose echinocandins. Withdraw any central venous catheter. Fundoscopy is needed. (5) De-escalation (1 recommendation): only applied when knowing susceptibility determinations and after 3 days of clinical stability. The higher rate of agreement was achieved in the optimization of microbiological tools and the withdrawal of the catheter, whereas the lower rate corresponded to de-escalation therapy and the use of scores. The management of invasive candidiasis in ICU patients requires the application of a broad range of knowledge and skills that we summarize in our recommendations. These recommendations may help to identify the potential patients, standardize their global management and improve their outcomes, based on the DELPHI methodology.

    Patients with suspected non-ST-segment elevation acute coronary syndromes (NSTEACS) constitute a heterogeneous population with variable outcomes. Risk stratification in this population of patients is difficult due to the complexity in patient risk profile. We conducted this study to characterize the value of clinical and electrocardiographic variables for risk stratification in an unselected population of consecutive patients with NSTEACS on admission. Thirty-five clinical and electrocardiographic variables at presentation in the emergency room of 18 hospitals were prospectively analyzed in 4,115 patients with NSTEACS and related with the outcomes at 90 days. We also developed a risk score using the variables found to be independent predictors of ischemic events to facilitate risk stratification. Cardiovascular mortality was 4.3% and the rate for the outcome of either cardiovascular death or nonfatal myocardial infarction was 6.9%. The only independent predictors of mortality were age, diabetes, peripheral vascular disease, postinfarction angina, Killip class > or = 2, ST-segment depression, and elevation of cardiac markers. A risk profile using the variables found to be independent predictors of events was calculated for cardiovascular mortality and for the combination of either death or nonfatal myocardial infarction. Event rates increased significantly in all subgroups of patients based on the number of independent risk factors as the risk score increased. Using these factors, 90-day mortality ranged from as low as 0.4% in patients with no risk factors to 21.1% for those with more than 4 risk factors. In conclusion, simple clinical and electrocardiographic data obtained at hospital admission allow an accurate risk stratification of patients with NSTEACS. In the PEPA registry, simple variables easy to obtain at admission appear to be a valuable tool in discerning between patients at very low and very high risk according to the cluster of factors for each patient. The risk score developed was obtained from an unselected population, representative of the whole spectrum of patients with NSTEACS, allowing identification of patients at different risks for adverse outcomes, and, therefore, permitting optimization of therapy.

Cohort studies have the advantage of being able to take into account many confounding factors and thus avoid biases (which is not the case with prevalence studies), but require significant human and financial resources. They were first adopted in the US, but are now more often applied in Europe. The results are relatively consistent, as they all show a statistically significant association between an increase in particulate pollution and cardiopulmonary mortality. Mortality from lung cancer is also associated with long term exposition to particles and sometimes to ozone or nitrogen oxides. Cerebrovascular diseases and sudden death of young children have also been associated with particulate pollution. The relationships are more powerful for long term than short term exposure but are also linear and without threshold. In order to explain these effects (today the causality of the relationship is certain) there are many possible factors, particularly regarding particulate exposures: an increase in cardiovascular risk biomarkers (fibrinogen, white blood cells, and platelets), atherosclerosis, chronic inflammation of lung tissues increased by acute exposure, etc. More and more studies address the interaction between gene and environment and even epigenetic phenomena which could be responsible of these effects. Public Health impact could be quantified. The European E&H surveillance program Apheis, for example, estimated that if PM2.5 levels remained below 15 microg/m(3), a 30 year old person could see his life expectancy increased by 1 month to 2 years, depending on the studied city. Finally, mortality is not the only relevant indicator for health effects of air pollution. ISAAC studies address asthma

    Özen, Asli E; Bibiloni, María del Mar; Pons, Antoni; Tur, Josep A

    2014-03-01

    Objetivo: Evaluar las diferencias en el consumo de alimentos funcionales entre los países europeos. Diseño: Revisión sistemática. La búsqueda bibliográfica se realizó en Medlars Online International Literature (MEDLINE), vía PubMed©, y Scopus. Se identificaron veintidós estudios que examinaron las diferencias en el consumo de alimentos funcionales entre los europeos. Resultados: Existen diferencias en la proporción de consumidores de alimentos funcionales entre los países europeos. Así, mientras los alimentos funcionales son muy populares en la mayoría de los países europeos como Finlandia, Suecia, Países Bajos, Polonia, España y Chipre, en algunos países como Dinamarca, Italia y Bélgica no lo son tanto. Un elevado porcentaje de adolescentes europeos mediterráneos (España y Chipre, pero no Italia) consume alimentos funcionales. La evaluación del consumo de alimentos funcionales en función del género es difícil, pues los resultados varían de estudio a estudio. Conclusiones: En los últimos años se ha extendido el consumo de alimentos funcionales en Europa, pero dicho consumo muestra grandes diferencias entre los europeos. Más investigaciones serán necesarias para averiguar las razones subyacentes tras estas diferencias y entender las necesidades de los consumidores de alimentos funcionales.

    The BOCCE project is a photometric and spectroscopic survey of Galactic open clusters (OCs), to be used as tracers of the properties and evolution of the Galactic disk. The main OCs parameters are derived in a precise and homogeneous way, and they will be used, for example, to determine the metallicity distribution in the Galactic disk and how it has evolved with time. We have presently data for about 40 OCs. We present here part of our last effort, concerning the photometric data obtained for NGC 2849.

    In this paper we give a complete description of the power weighted inequalities, of strong, weak and restricted weak type for the pair of Riesz transforms associated with the Laguerre function system \\{mathcal{L}_k^{α}\\}, for any given α>-1. We achieve these results by a careful estimate of the kernels: near the diagonal we show that they are local Calderón-Zygmund operators while in the complement they are majorized by Hardy type operators and the maximal heat-diffusion operator. We also show that in all the cases our results are sharp.

    We prove that for the cases X=mathcal{C}(K) ( K infinite) and X= L 1(μ) (μ σ-finite and atomless) it holds that every slice of the unit ball of the N-fold symmetric tensor product of X has diameter two. In fact, we prove more general results for weak neighborhoods relative to the unit ball. As a consequence, we deduce that the spaces of N-homogeneous polynomials on those classical Banach spaces have no points of Fréchet differentiability.

    McQuestion, Michael J; Velasquez, Anibal

    2006-07-01

    We evaluate the joint effects of two targeted Peruvian health programs on a mother's choice of whether to deliver in a public emergency obstetric care (EmOC) facility. The national maternal and child health insurance, or SMI Program, provided delivery care coverage to Peru's poorest households beginning in 1998. During 1996-2002, Proyecto 2000 sought to improve the quality of EmOC and increase utilization of public EmOC facilities in the districts reporting the highest maternal and neonatal mortality levels. Our data come from the Proyecto 2000 endline evaluation, which sampled 5335 mothers living in the catchment areas of 29 treatment and 29 matched control EmOC facilities. Using propensity scoring and two quality of care indices, we find significantly higher quality of care in Proyecto 2000 treatment facilities. Using variance components logistic models, we find a mother enrolled in the SMI Program was more likely to have delivered her last child in a public EmOC, controlling for household constraints. Residence in a Proyecto 2000 treatment area did not significantly affect the choice. A cross-level interaction term was insignificant, indicating the two program effects were independent.

    En este artículo presentamos el proyecto de capacitación llevado a cabo en comunidades de la sierra y costa de Oaxaca, México, desde 1991, por el Centro de Capacitación Integral para Promotores Comunitarios (CECIPROC). La decisión de hacer este trabajo en Oaxaca responde a que ese estado ocupa uno de los primeros lugares de marginación y de desnutrición en menores de 5 años. El objetivo es describir un modelo de capacitación y compartir parte de las experiencias derivadas, tanto del modelo como del trabajo realizado en las distintas áreas (nutrición y alimentación, salud comunitaria, ecología y etnobotánica, y educación y organización), por promotores mujeres y hombres en sus comunidades.La experiencia obtenida en 24 años muestra la factibilidad técnica y social del proyecto en el ámbito de la salud, el reconocimiento social del proyecto del CECIPROC como un organismo civil que ha aportado alternativas como solución a la problemática de salud, el hacer suyo el proyecto por algunos promotores y los diferentes obstáculos a los que se ha enfrentado. Enfatizamos el hecho de que la situación socioeconómica y política prevaleciente en el estado de Oaxaca es una limitante para el buen desarrollo de los programas colectivos de salud, e insistimos en la necesidad de compartir nuestras experiencias para que puedan ser utilizadas en la planificación y ejecución de otros proyectos.

    Traditional Informed Consent is becoming increasingly inadequate, especially in the context of research biobanks. How much information is needed by patients for their consent to be truly informed? How does the quality of the information they receive match up to the quality of the information they ought to receive? How can information be conveyed fairly about future, non-predictable lines of research? To circumvent these difficulties, some scholars have proposed that current consent guidelines should be reassessed, with trust being used as a guiding principle instead of information. Here, we analyse one of these proposals, based on a Participation Pact, which is already being offered to patients at the Istituto Europeo di Oncologia, a comprehensive cancer hospital in Milan, Italy.

     Introducción: obesidad e inactividad física son importantes factores de riesgo para el desarrollo de hipertensión en adultos. No obstante, hay poca evidencia sobre el efecto de estos factores de riesgo en el desarrollo de hipertensión en población infantil. Objetivo: investigar la asociación del estado nutricional, niveles de actividad física y etnicidad con niveles de hipertensión en escolares entre 6 y 13 años de edad. Métodos: un total de 418 escolares de ascendencia étnica europea (n = 311) y mapuche (n = 107) fueron participantes de este estudio transversal. Se midió el peso, talla, índice de masa corporal (IMC) y presión arterial, utilizando protocolos estandarizados. Resultados: no se encontraron diferencias significativas en IMC, estado nutricional y presión arterial entre niños con ascendencia europea y mapuche. No obstante, la prevalencia de prehipertensión (21,3% vs. 11,1%) e hipertensión (28,9% vs. 18,6%) fue significativamente mayor en escolares mapuches en comparación con europeos, respectivamente. Escolares con ascendencia mapuche tienen un mayor riesgo de desarrollar prehipertensión o hipertensión que escolares con ascendencia europea (OR: 1,92 [1,19 a 3,06], p < 0,01). La prevalencia de hipertensión aumenta significativamente en ambos grupos étnicos con el incremento de IMC y bajos niveles de actividad física. Conclusiones: el riesgo de desarrollar prehipertensión o hipertensión es mayor en población infantil ascendiente de mapuches que ascendiente de europeos y este riesgo se ve acentuado con el incremento de obesidad y bajos niveles de actividad física.

    Los Atlas de Aves son proyectos nacionales o regionalies para trazar en mapas la distribucion en reproduccion de cada especie de ave. Ese procedimiento se esta usando en Europa, Australia, Nueva Zelanda, Norteamerica, y partes de Africa. El tama?o de los cuadrados varia de medio grado de latitud y Iongitud hasta 5 x 5 km. El trabajo de campo de cada proyecto exige aproxlmadamente cinco a?os, pero los aficionados pueden llevar a cabo la mayor parte del trabajo. Es posible almacenar los resultados en un computador personal. Hay muchos beneficios: (I) se presenta la distribucion corriente de las aves de la nacion, del estado, o de la Iocalidad; (2) se desarrolla nueva informacion especialmente sobre especies raras o en peligro; (3) se descubren areas que tienen una avlfauna sobresaliente o habitats raros y ayuda a su proteccion, (4) se documentan cambios de dlstribucion; (5) se pueden usar para documentar cambios de poblacion, especialmente en los tropicos donde otros metodos son mas dificiles de usar porque hay muchas especies y no hay muchos observadores calificados en la identificacion de sonidos de las aves; (6) son proyectos buenos de investigacion para estudiantes graduados; (7) los turistas y los jefes de excursiones de historia natural pueden contribuir con muchas informaciones

  9. A prospective cohort study of modifiable risk factors for gestational diabetes among Hispanic women: design and baseline characteristics.

    Women diagnosed with gestational diabetes mellitus (GDM) are at high risk for future diabetes, with rates of GDM consistently higher in Hispanic than non-Hispanic white women. Currently recognized risk factors for GDM are absent in up to half of affected women, and studies addressing modifiable risk factors for GDM in Hispanic women are sparse. Proyecto Buena Salud is an ongoing prospective cohort study of Hispanic women in Massachusetts designed to assess physical activity, psychosocial stress, and GDM risk. Bilingual interviewers recruit prenatal care patients early in pregnancy and assess activity, trait anxiety, perceived stress, and depressive symptoms using validated questionnaires. Baseline characteristics of the first 632 participants are presented. Women were predominantly young (69% <24 years), were unmarried (87%), and had low levels of education (48% had less than high school). Women with high acculturation were less likely to live with a partner (OR: 0.6, 95% CI 0.4-0.8) than women with low acculturation. Few participants met physical activity guidelines during pregnancy (5.2%). Levels of perceived stress (mean 26.9 +/- 7.1), trait anxiety (mean 41.6 +/- 10.4), and depressive symptoms (33.2%) were high. Proyecto Buena Salud represents a high-risk population of pregnant Hispanic women who are predominantly inactive, with higher levels of perceived stress, trait anxiety, and depressive symptoms compared to predominantly non-Hispanic white cohorts studied earlier. Therefore, Proyecto Buena Salud provides a unique opportunity to prospectively evaluate modifiable risk factors for GDM. Findings will inform prenatal behavioral intervention programs designed to address modifiable GDM risk factors.

    Introduccion. Muchos de los instrumentos neuropsicologicos utilizados en España se han normalizado en poblacion hispanohablante procedente de Estados Unidos y Sudamerica, con grupos de edad y caracteristicas restrictivas. Utilizar este tipo de normas disminuye potencialmente su representatividad, la interpretacion de los resultados y las decisiones clinicas. Este estudio se enmarca dentro del proyecto Normacog, con el fin de estandarizar instrumentos neuropsicologicos en una muestra representativa de la sociedad española. Objetivo. Presentar la metodologia de normalizacion llevada a cabo en el proyecto Normacog y las caracteristicas sociodemograficas de la poblacion española y de los participantes incluidos en el estudio. Sujetos y metodos. Se reclutaron 711 participantes (rango: 18-90 años) de diferentes areas geograficas de España, incluyendo los datos sociodemograficos, medicos, habitos habituales, lengua materna, bilinguismo y dominancia manual. Cada participante completo 19 instrumentos que evaluaban un amplio rango de dominios cognitivos, como memoria verbal y visual, atencion, funciones ejecutivas, velocidad de procesamiento o fluidez y denominacion verbal. Resultados. La muestra final normativa refleja las caracteristicas sociodemograficas y la representatividad de la poblacion española de acuerdo con los rangos de edad, educacion y sexo. Conclusiones. Se describe la metodologia de normalizacion y las caracteristicas de la muestra incluida en el estudio multicentrico Normacog, mediante el cual se llevara a cabo la estandarizacion y normalizacion de instrumentos neuropsicologicos, teniendo en cuenta las caracteristicas sociodemograficas propias de la poblacion española. El proyecto Normacog proporciona datos normativos adecuados a nuestro medio cultural, y es esencial para poder realizar un diagnostico clinico y neuropsicologico fiable.

    El proyecto µARGO propone el desarrollo, construcción y operación del Observatorio Espacial de Rayos Gamma, que operará en una órbita terrestre. Este observatorio constará de un telescopio con capacidad de medir simultáneamente dirección de incidencia y polarización de rayos Gamma en dos rangos de energía: 50 KeV - 3 MeV y 10 MeV - 1 GeV. Para ello se usarán detectores de silicio de última generación y microelectrónica adaptada a la configuración. La masa total en órbita del observatorio estará en el orden de los 60 - 100 kg. dependiendo de la geometría adoptada lo que permitirá minimizar costos de desarrollo y construcción, sin perder por ello calidad en su misión científica. ? Desde el punto de vista energético μARGO cubrirá el rango cubierto por COMPTEL y EGRET del CGRO, duplicando como mínimo la resolución angular de ambos con una reducción de peso de dos órdenes de magnitud. En adición, μARGO podr´ medir la polarización incidente de los rayos energéticos. Si bien existen otros dos proyectos en marcha (GLAST y AGILE) para reemplazar EGRET que serán lanzados antes que μARGO, estos proyectos no están diseñados para medir polarización ni tampoco cubren el rango mas bajo de energía arriba mencionado.

    Developing effective conservation programs that positively impact the survival of a species while considering the needs of local communities is challenging. Here we present an overview of the conservation program developed by Proyecto Tití to integrate local communities in the conservation of Colombia's critically endangered primate, the cotton-top tamarin (Saguinus oedipus). Our comprehensive assessment of the threats effecting the long-term survival of the cotton-top tamarin allowed us to establish the primary components of our program. Proyecto Tití has three areas of emphasis: (1) scientific studies detailing the biology and long-term survival of the cotton-top tamarin, (2) conservation education programs to increase public awareness and conservation knowledge, and (3) community empowerment programs that demonstrate a valuable economic incentive to protecting wildlife and forested areas in Colombia. This integrated approach to conservation that involves local communities in activities that benefit individuals, as well as wildlife, has proven to be remarkably effective in protecting cotton-top tamarins and their forested habitat. Our bindes program, which uses small cook stoves made from clay, has demonstrated a marked reduction in the number of trees that have been harvested for firewood. Developing environmental entrepreneurs, who create products made from recycled plastic for sale in national and international markets, has had a significant impact in reducing the amount of plastic that has been littering the environment and threatening the health of wildlife, while creating a stable economic income for rural communities. Proyecto Tití has provided economic alternatives to local communities that have dramatically reduced the illegal capture of cotton-top tamarins and forest destruction in the region that has positively impacted the long-term survival of this critically endangered primate.

    We consider the problem of wave turbulence generated by singularities from an experimental point of view. We study a system of Faraday waves interacting with waves generated by a wave-maker driven with a random forcing. We measure the temporal fluctuations of the surface wave amplitude at a given location and we show that for a wide range of forcing parameters the surface height displays a power-law spectra that greatly differs from the one predicted by the WT theory. In the capillary region the power spectrum turns out to be proportional to f-5, which we believe is due to singularities moving across the system. Proyecto Postdoctorado Fondecyt Nro 3160032.

The genome encodes for at least 1751 enzymatic reactions that account for the known pattern of C, N, P and S utilization by this strain. Based on the potential of this strain to thrive in the presence of organic solvents and the subclasses of enzymes encoded in the genome, its metabolic map can be drawn and a number of potential biotransformation reactions can be deduced. This information may prove useful for adapting desired reactions to create value-added products. This bioengineering potential may be realized via direct transformation of substrates, or may require genetic engineering to block an existing pathway, or to re-organize operons and genes, as well as possibly requiring the recruitment of enzymes from other sources to achieve the desired transformation.

    Quantum memories for light allow a reversible transfer of quantum information between photons and long lived matter quantum bits. In atomic ensembles, this information is commonly stored in the form of single collective spin excitations (spin-waves). In this work we demonstrate that we can actively control the dephasing of the spin-waves created in a quantum memory based on a cold Rb87 atomic ensemble. The control is provided by an external magnetic field gradient, which induces an inhomogeneous broadening of the atomic hyperfine levels. We show that acting on this gradient allows to control the dephasing of individual spin-waves and to induce later a rephasing. The spin-waves are then mapped into single photons, and we demonstrate experimentally that the active rephasing preserves the sub-Poissonian statistics of the retrieved photons. Finally we show that this rephasing control enables the creation and storage of multiple spin-waves in different temporal modes, which can be selectively readout. This is an important step towards the implementation of a functional temporally multiplexed quantum memory for quantum repeaters.

    Empirical models such as the Eldred standard model are commonly used for rocket noise prediction. Such models directly provide a definition of the Sound Pressure Level through the quadratic pressure term by uncorrelated sources. In this paper, an improvement of the Eldred Standard model has been formulated. This new formulation contains an explicit expression for the acoustic pressure of each noise source, in terms of amplitude and phase, in order to investigate the sources correlation effects and to propagate them through a wave equation. In particular, the correlation effects between adjacent and not-adjacent sources have been modeled and analyzed. The noise prediction obtained with the revised Eldred-based model has then been used for formulating an empirical/BEM (Boundary Element Method) hybrid approach that allows an evaluation of the scattering effects. In the framework of the European Space Agency funded program VECEP (VEga Consolidation and Evolution Programme), these models have been applied for the prediction of the aeroacoustics loads of the VEGA (Vettore Europeo di Generazione Avanzata - Advanced Generation European Carrier Rocket) launch vehicle at lift-off and the results have been compared with experimental data.

    La leishmaniasis es una enfermedad causada por parásitos obligados intracelulares pertenecientes al género Leishmania y que reconoce tres formas clínicas principales: cutánea, visceral y mucocutánea. Es una patología del grupo de las "enfermedades desatendidas". Es la única enfermedad tropical transmitida a través de vectores que se ha mantenido endémica por décadas en el sur de Europa. La leishmaniasis visceral representa la forma más grave. Se caracteriza por fiebre, pérdida de peso, anemia y hepatoesplenomegalia. Su período de incubación oscila entre 2 semanas y 18 meses. La leishmaniasis se considera una enfermedad reemergente a nivel mundial. Algunos de los factores que favorecen esta situación son los cambios en las condiciones climáticas, migraciones y urbanizaciones deficitarias en saneamiento ambiental. Se presenta el caso de un niño europeo que estaba vacacionando en Córdoba y fue derivado a nuestro Hospital por fiebre y pancitopenia, lo que generó un abordaje multidisciplinario con resolución clínica favorable.

    I would like to share my experience ofusing the computer for creating art. I am a graphic designer originally trained without any exposure to the computer. I graduated in July of 1994 from a four-year curriculum of graphic design at the Istituto Europeo di Design in Milan Italy. Italy is famous for its excellent design capability. Art and beauty influence the life ofnearly every Italian. Everywhere you look on the streets there is art from grandiose architecture to the displays in shop windows. A keen esthetic sense and a search and appreciation for quality permeate all aspects of Italian life, manifesting in the way people cut their hair, the style ofthe clothes and how furniture and everyday objects are designed. Italian taste is fine-tuned to the appreciation ofrefined textiles and quality materials are often enhanced by simple design. The Italian culture has a long history ofexcellent artisanship and good craftsmanship is highly appreciated. Gadgets have never been popular in Italian society. Gadgets are considered useless objects which add nothing to a person's life, and since they cost money they are actually viewed as a waste. The same is true for food, exception made in the big cities filled with tourists, fast food chains have never survived. Genuine and simple food is what people truly desire. A typical Italian sandwich, for example, is minimalist, the essential ingredients are left alone without additional sauces because if something is delicious by itselfwhy would anyone want to disgnise its taste?

    Introduccion. Durante las ultimas decadas han surgido numerosas investigaciones que documentan las dificultades de comprension lectora que muestran las personas con trastorno del espectro autista (TEA), incluidas aquellas que tienen la inteligencia preservada. Estas dificultades pueden condicionar su trayectoria educativa e incidir de forma directa sobre su inclusion social, autonomia y acceso al mundo laboral. Desarrollo. Este articulo presenta el trabajo elaborado por un equipo multidisciplinar en el marco de un proyecto financiado por la Union Europea. Es un documento explicativo que pretende justificar las necesidades que tiene la poblacion de personas con TEA de alto funcionamiento para acceder a la informacion escrita. Es un proyecto que esta desarrollando una herramienta informatica (Open Book) que no solo esta siendo diseñada 'para' personas con TEA, sino que esta siendo desarrollada 'con' personas con TEA. Conclusion. Tanto la poblacion infantil como la poblacion adulta de personas con TEA muestran dificultades en todos los componentes formales del lenguaje escrito. La herramienta tiene que ser flexible y favorecer su uso individualizado, para dar respuesta a la enorme heterogeneidad de esta poblacion.

  4. Dipole-exchange modes in transversely magnetized ferromagnetic stripes

    2014-03-01

    We present a theory of dipole-exchange modes in transversely magnetized ferromagnetic stripes of rectangular cross sections: a comparison is made with experimental results on Permalloy stripes. The model applies to very thin stripes (of the order of the exchange length): the magnetization is considered uniform over their thickness, and we consider modes of long wavelength along the longitudinal direction of the stripes. An applied magnetic field saturates the stripes along the transverse direction, and we also consider the effect of the exchange and dipolar fields. Under these assumptions we obtain the frequencies and shapes of the modes either considering free or pinned boundary conditions. We obtain good agreement with measurements of the frequency spectra in Permalloy nano wires of several rectangular cross sections: this happens for modes with appreciable amplitude throughout the samples. There is frequency disagreement for edge modes due to limitations of the model, since the effects of roughness, corners and imperfections at the edges of the samples are quite relevant in this case.

    En el marco de un proyecto de investigación-acción que se implementó en Venezuela de 2009 a 2013 se buscó empoderar (empower) a activistas sociales y pacientes en la lucha contra el cáncer de mama (CM). Este proyecto se puso en marcha en un contexto de alta polarización política y social en el marco de la llamada «Revolución bolivariana». A partir de una perspectiva ecológica de la comunicación y el activismo en salud, que integra los niveles interpersonal, grupal y social, se celebraron una serie de actividades orientadas a desarrollar las habilidades de vocería de ciudadanos, especialmente de mujeres, y ampliar las redes de cooperación entre diversos sectores, al mismo tiempo que se perfiló una visión consensuada entre actores sociales e institucionales sobre una respuesta nacional contra el CM. Una comunicación horizontal y participativa permitió que se escuchara la voz de actores usualmente marginalizados en las políticas sanitarias. PMID:27867911

    El Reclutamiento y la Retención (R&R) de participantes es fundamental para el éxito de estudios y para el desarrollo de intervenciones preventivas. El R&R de participantes determina la validez y efectividad de estos programas. En este trabajo examinamos algunos de los factores que facilitan y dificultan el R&R en los proyectos preventivos y ofrecemos algunas alternativas para mejorar los índices de R&R. Realizamos dos estudios, en el primero administramos el Instrumento de Informatión, Motivatión y Conductas-Español (IIMC-E) a un grupo de 26 parejas heterosexuales (52 participantes). En el segundo, entrevistamos a 5 parejas VIH discordantes (10 participantes). Encontramos que el 75% de los/las participantes indicó que su trabajo era una de las principales barreras que dificultan la asistencia a las actividades. Otras barreras son las responsabilidades laborales y familiares. Encontramos que la principal barrera fue el miedo a la revelación del estado serlógico. Los principales facilitadores del R&R son la coordinación adecuada y el seguimiento telefónico ofrecido por parte del personal del proyecto. Concluimos que en el desarrollo e implantación de programas de prevención el investigador/a debe tomar en cuenta la adaptación de aspectos logísticos como la disponibilidad y las necesidades particulares de los/las participantes.

    The authors evaluated the validity and reliability of the Block Kids Food Frequency Questionnaire (BKFFQ) and the Block Kid Screener (BKScreener) in Mexican American children living along the Texas-Mexico border who participated in the National Institutes of Health-funded Proyecto Bienestar Laredo. The Bienestar/NEEMA health program is a school-based diabetes and obesity control program, and the Proyecto Bienestar Laredo is the translation of the Bienestar/NEEMA health program to 38 elementary schools in Laredo, Texas. Par ticipants included 2,376 eight-year-old boys (48%) and girls (52%) from two school districts in Laredo. Two Food Frequency Questionnaire (BKFFQ and BKScreener) dietary intakes were collected, and an expert panel of nutritionist assigned a classification response quality of "Good," "Questionable," and "Poor," based on playfulness (systematic or nonrandom) patterns and completion rates. In addition, both instruments were assessed for reliability (test-retest) in 138 students from a San Antonio School District. Children's height, weight, percentage body fat, reported family history of diabetes, and Texas Assessments of Knowledge and Skills in reading and mathematics scores were collected. This study showed that for Mexican American children living along the Texas-Mexico border, within the time constraints of the classroom, BKScreener yielded better data than the BKFFQ.

Exploramos los traslapes espaciales entre los stocks de carbono, la biodiversidad, las amenazas proyectadas de deforestación y la ubicación de proyectos REDD+ en Indonesia, un país tropical a la vanguardia del desarrollo REDD+. Para la biodiversidad, reunimos datos sobre la distribución de vertebrados terrestres (hábitats de anfibios, mamíferos, aves y reptiles) y plantas (modelos de distribución de especies para ocho familia). Después investigamos la congruencia entre las diferentes medidas de la riqueza de la biodiversidad y los stocks de carbono en la escala nacional y sub–nacional. Finalmente mapeamos proyectos REDD+ activos e investigamos la densidad de carbono y la riqueza potencial de la biodiversidad y modelamos presiones de deforestación dentro de estos bosques en relación con áreas protegidas y no protegidas. Hubo poco traslape interno entre los diferentes hotspots (el 10% más rico de las celdas) de riqueza de especies. Tampoco hubo congruencia espacial consecuente entre los stocks de carbono y las medidas de la biodiversidad: una correlación negativa débil en la escala nacional enmascaró las relaciones altamente variables y no-lineales isla por isla. Los proyectos REDD+ actuales estuvieron ubicados preferencialmente en áreas con una riqueza total de especies y con una riqueza de especies amenazadas más altas pero con densidades de carbono más bajas que en las áreas protegidas y los bosques sin protección. Aunque un cuarto del área total de estos proyectos REDD+ está bajo una presión de deforestación relativamente alta, la mayoría del área REDD+ no lo está. Por lo menos en Indonesia

Clínica Baviera, Instituto Oftalmológico Europeo, Bilbao, Spain. Retrospective case series review. The medical records of 55 255 patients (108 014 eyes) who had LASIK and surface ablation were reviewed to identify cases of infectious keratitis. The incidence, risk factors, clinical course, days to diagnosis, treatment, and final visual outcomes were recorded. These data were compared with previously published data of 221 437 eyes that received postoperative tobramycin alone. Post-LASIK infectious keratitis was diagnosed in 10 eyes (9 patients) and post-surface ablation infectious keratitis in 11 eyes (10 patients). The onset of infection was early in 40.00% of cases after LASIK and in 36.36% after surface ablation. Cultures were positive in 2 cases after surface ablation. Immediate flap lifting and irrigation with antibiotics were performed in all eyes after LASIK. The final corrected distance visual acuity was 20/20 or better in 7 cases after LASIK (70.00%) and 7 cases after surface ablation (63.64%) and 20/40 or better in all cases after LASIK or surface ablation. The incidence of infectious keratitis decreased from 0.025% to 0.011% (P < .001) per procedure after LASIK and from 0.200% to 0.066% (P < .001) after surface ablation. Infectious keratitis was less frequent after LASIK than after surface ablation. The frequency of infection, mainly early-onset infection, was lower when the postoperative treatment was tobramycin and moxifloxacin rather than tobramycin alone.

    Summary Prophylactic central neck dissection in papillary thyroid cancer is controversial. In this retrospective cohort study, the aim was to assess possible advantages of prophylactic central neck dissection with total thyroidectomy in cN0 papillary thyroid cancer. A total of 244 consecutive patients with papillary thyroid cancer, without clinical and ultrasound nodal metastases (cN0), were evaluated out of 1373 patients operated for a thyroid disease at the Istituto Europeo di Oncologia, Milan, Italy from 1994 to 2006. Of these 244 patients, 126 (Group A) underwent thyroidectomy with central neck dissection, while 118 (Group B) underwent thyroidectomy alone. Demographic, clinical and pathological features were analysed. Overall recurrence rate was 6.3% (8/126) in Group A and 7.7% (9/118) in Group B, with a mean follow-up of 47 (Group A) and 64 (Group B) months. In Group A patients, 47% were pN1a and all patients with recurrence had nodal involvement (p = 0.002). Survival rate did not differ in the two groups. Nine patients were lost to follow-up. Group A patients were older and their tumours were larger in size; according to the pT distribution, a higher extra-capsular invasion rate was observed. The two groups were equivalent as far as concerns histological high risk variants and multifocality. Nodal metastases correlated with stage: pT1-2 vs. pT3-T4a, p = 0.0036. A lower risk of nodal metastases was related to thyroiditis (p = 0.0034). In conclusion, central neck metastases were predictive of recurrence without influencing prognosis. From data obtained, possible greatest efficacy of central neck dissection in pT3-4 papillary thyroid cancer without thyroiditis is suggested. PMID:20111614

    Introducción y objetivos: tanto el exceso de peso como la delgadez se relacionan con diversos problemas de salud que pueden continuar hasta la edad adulta. Los objetivos de este estudio fueron estimar la prevalencia de delgadez, sobrepeso y obesidad en escolares de 4-6 años de las provincias de Cuenca y Ciudad Real (España), mediante criterios del Grupo Internacional de Trabajo sobre Obesidad y de la Organización Mundial de la Salud, y comparar estas cifras con otros estudios europeos. Métodos: estudio observacional-transversal que incluyó a 1.585 escolares realizado en septiembre de 2013. Las mediciones de peso y talla fueron realizadas por enfermeras entrenadas y mediante procedimientos estandarizados. El estatus ponderal se definió según los criterios del Grupo Internacional de Trabajo sobre Obesidad y la Organización Mundial de la Salud. Resultados: según criterios del Grupo Internacional de Trabajo sobre Obesidad, la prevalencia de delgadez, sobrepeso y obesidad fue del 20,51%, 11,84% y 8,58%, respectivamente; y del 3,97%, 13,92% y 10,79% cuando se utilizaron los criterios de la Organización Mundial de la Salud. No se encontraron diferencias estadísticamente significativas por sexo ni provincia para ninguna categoría de estatus ponderal. Para ambos criterios, la prevalencia de delgadez fue menor a medida que aumentaba la edad, mientras que la prevalencia de sobrepeso/obesidad fue mayor. Conclusiones: la prevalencia de exceso de peso podría haber tocado techo en España, aunque continúa siendo un importante problema de salud pública. El aumento de la prevalencia de bajo peso debería ocupar un lugar relevante en las intervenciones de salud pública.

Se carece de una publicación que estudie todos los casos identificados en el mundo, por lo que el objetivo de este artículo estriba en describir los casos y defunciones por el nuevo coronavirus. Métodos: se revisaron las publicaciones en línea de la Organización Mundial de la Salud, del Centro Europeo para el Control y Prevención de Enfermedades y de la Eurosurveillance. Se realizó un análisis descriptivo de los casos, se calcularon los límites para proporciones con un alfa del 0.05 por prueba de Wilson y una prueba t de Student para diferencia de medias. Resultados: son 17 casos confirmados y 11 defunciones en varios países de Asia y Europa; predominaron los pacientes masculinos. La tasa de letalidad fue de 64.70 %; los que fallecieron se hospitalizaron cinco días después de los primeros síntomas. Se carece de publicaciones que describan la historia natural de la enfermedad; sin embargo, lo descrito en las publicaciones de Europa coincide con los resultados de este estudio. Conclusión: es necesario continuar con la vigilancia epidemiológica y la realización de nuevos estudios para evaluar el impacto de esta enfermedad en la salud pública internacional.

    Definition of the optimal treatment schedule for high-risk prostate cancer is under debate. A combination of photon intensity modulated radiotherapy (IMRT) on pelvis with a carbon ion boost might be the optimal treatment scheme to escalate the dose on prostate and deliver curative dose with respect to normal tissue and quality of dose distributions. In fact, carbon ion beams offer the advantage to deliver hypofractionated radiotherapy (RT) using a significantly smaller number of fractions compared to conventional RT without increasing risks of late effects. This study is a prospective phase II clinical trial exploring safety and feasibility of a mixed beam scheme of carbon ion prostate boost followed by photon IMRT on pelvis. The study is designed to enroll 65 patients with localized high-risk prostate cancer at 3 different oncologic hospitals: Istituto Europeo di Oncologia, Fondazione IRCCS Istituto Nazionale dei Tumori, and Centro Nazionale di Adroterapia Oncologica. The primary endpoint is the evaluation of safety and feasibility with acute toxicity scored up to 1 month after the end of RT. Secondary endpoints are treatment early (3 months after the end of RT) and long-term tolerability, quality of life, and efficacy. The study is not yet recruiting; in silico studies are ongoing and we expect to start recruitment by 2017. The present clinical trial aims at improving the current treatment for high-risk prostate cancer, evaluating safety and feasibility of a new RT mixed-beam scheme including photons and carbon ions. Encouraging results are coming from carbon ion facilities worldwide on the treatment of different tumors including prostate cancers. Carbon ions combine physical properties allowing for high dose conformity and advantageous radiobiological characteristics. The proposed mixed beam treatment has the advantage to combine a photon high conformity standard of care IMRT phase with a hypofractionated carbon ion RT boost delivered in a short overall

    The YMCA-Silicon Valley Racial and Ethnic Approaches to Community Health (REACH) U.S. Proyecto Movimiento (PM) Action Community project is a community-based partnership that aims to reduce the prevalence of diabetes among Latinos in the Greater Gilroy, California, area by delivering a prevention campaign across generations. A critical component of PM has been the creation of a Youth Health Advocate (YHA) afterschool club at three public high schools in Gilroy. The YHAs, who are trained on health, nutrition, diabetes, basic leadership skills, and digital storytelling, are at the forefront of the campaign targeting Gilroy youth. In their own words, the YHAs describe why they decided to become a YHA, the positive health impact of YHA activities on themselves and their family, and the positive impact on burgeoning leadership skills. The voices of YHAs in this prevention campaigns have brought value to the PM evaluation, and this qualitative element bears further examination in other community-based prevention campaigns.

    PARTNeR is an acronym for Proyecto Académico con el Radio Telescopio de NASA en Robledo (Academic Project with the NASA Radio Telescope at Robledo). It is intended for general Astronomy outreach and, in particular, radioastronomy, throughout Spanish educational centres. To satisfy this target, a new educational material has been developed in 2007 to help not only teachers but also students. This material supports cross curricular programs and provides with the possibility of including Astronomy in related subjects like Physics, Chemistry, Technology, Mathematics or even English language. In this paper, the material that has been developed will be shown in detail and how it can be adapted to the disciplines from 4th year ESO (Enseñanza Secundaria Obligatoria-Compulsory Secondary Education) to High School. The pedagogic results obtained for the first year it has been implemented with students in classrooms will also be presented.

    We present new deep co-adds of data taken within Stripe 82 of the Sloan Digital Sky Survey (SDSS), especially stacked to reach the faintest surface brightness limits of this data set. Our reduction puts special emphasis on preserving the characteristics of the background (sky + diffuse light) in the input images using a non-aggressive sky subtraction strategy, resulting in an exquisite quality on extremely faint structures. The IAC Stripe 82 co-adds offer a rather unique possibility to study the low surface brightness Universe like stellar haloes and disc truncations, low surface brightness, tidal galactic interactions, extremely faint dwarf galaxies, intra-cluster light or diffuse light from galactic dust. The imaging data is publicly available at http://www.iac.es/proyecto/stripe82/.

    PARTNeR (Proyecto Académico con el Radio Telescopio de NASA en Robledo, Academic Project with the NASA Radio Telescope at Robledo) is an educational program that allows high school and undergraduate students to control a 34 meter radio telescope and conduct radio astronomical observations via the internet. High-school teachers who join the project take a course to learn about the science of radio astronomy and how to use the antenna as an educational resource. Also, teachers are provided with learning activities they can do with their students and focused on the classroom implementation of the project within an interdisciplinary framework. PARTNeR provides students with firsthand experience in radio astronomy science. Thus, remote radio astronomical observations allow students to learn with a first rate scientific equipment the basics of radio astronomy research, aiming to arouse scientific careers and positive attitudes toward science. In this contribution we show the current observational programs and some recent results.

    This article explores distinctive features of a 5-year international education development project set in rural northern Peru (PROMEB, the Proyecto de Mejoramiento de la Educación Básica). Grounded within a partnership between teacher educators from Peru, Mexico and Canada, and rural Peruvian teachers, students and their communities, we offer reflections on a teacher education initiative which sought to support action-orientated inquiries as a mechanism for school/community development. Set against a background of poverty, hunger, isolation and an "educational crisis", we outline our pedagogy and describe two projects. We then reflect on the influences of our engagements and on associated tensions and ambiguities in our methods. We hope that such discussions might offer insights for others involved in international school/community development projects of this type.

    Levato, H.; Malaroda, S.; García, B.; Grosso, M.

    NGC 2287 contiene 100 estrellas con buena fotometría y 40 con tipos MK. En 1979 Levato et al., usando la técnica de la clasificación espectral, descubrieron que la mayoría de las estrellas en el rango B8-A0 eran binarias espectroscópicas con una inusual proporción de binarias con dos espectros. El presente proyecto tuvo el propósito de confirmar la naturaleza binaria de los miembros del cúmulo. Hemos obtenido espectros con resolución 14000 de 15 estrellas clasificadas como binarias. Los espectros, que abarcan la región λ 3500-λ 6000 Å, permitieron confirmar la naturaleza binaria de varias de las estrellas en la muestra. Hacemos notar el considerable interés astrofísico de este cúmulo abierto.

    The Environmental Health/Home Safety Education Project (Proyecto de Salud Ambiental y Seguridad en el Hogar) has been developed in response to a wide array of severe and often preventable environmental health issues occurring in and around homes on the U.S.-Mexico border. Utilizing well-trained community members, called promotoras , homes are visited and assessed for potential environmental hazards, including home fire and food safety issues. Data analyzed from project years 2002 to 2005 shows a significant impact in knowledge levels and initial behavior change among targeted participants as it relates to fire and food safety issues. Since the initiation of the project in 1999, hundreds of participants have improved their quality of life by making their homes safer. The project has proven to be sustainable, replicable, flexible, and attractive to funders.

  7. Concept Mapping Using Cmap Tools to Enhance Meaningful Learning

    NASA Astrophysics Data System (ADS)

    Cañas, Alberto J.; Novak, Joseph D.

    Concept maps are graphical tools that have been used in all facets of education and training for organizing and representing knowledge. When learners build concept maps, meaningful learning is facilitated. Computer-based concept mapping software such as CmapTools have further extended the use of concept mapping and greatly enhanced the potential of the tool, facilitating the implementation of a concept map-centered learning environment. In this chapter, we briefly present concept mapping and its theoretical foundation, and illustrate how it can lead to an improved learning environment when it is combined with CmapTools and the Internet. We present the nationwide “Proyecto Conéctate al Conocimiento” in Panama as an example of how concept mapping, together with technology, can be adopted by hundreds of schools as a means to enhance meaningful learning.

  9. Observations of rapid-fire event tremor at Lascar volcano, Chile

    1996-01-01

    During the Proyecto de Investigacio??n Sismolo??gica de la Cordillera Occidental (PISCO '94) in the Atacama desert of Northern Chile, a continuously recording broadband seismic station was installed to the NW of the currently active volcano, Lascar. For the month of April, 1994, an additional network of three, short period, three-component stations was deployed around the volcano to help discriminate its seismic signals from other local seismicity. During the deployment, the volcanic activity at Lascar appeared to be limited mainly to the emission of steam and SO2. Tremor from Lascar is a random, ??rapid-fire?? series of events with a wide range of amplitudes and a quasi-fractal structure. The tremor is generated by an ensemble of independent elementary sources clustered in the volcanic edifice. In the short-term, the excitation of the sources fluctuates strongly, while the long-term power spectrum is very stationary.

  10. Enhancing the natural removal of As in a reactive fluvial confluence receiving acid drainage

    Fluvial confluences are natural reactors that can determine the fate of contaminants in watersheds receiving acid drainage. Hydrological, hydrodynamic and chemical factors determine distinct conditions for the formation of suspended particles of iron and aluminum oxyhydroxides. The chemical and physical properties of these particle assemblages (e.g. particle size, chemical composition) can vary according to inflow mixing ratios, hydrodynamic velocity profiles, and chemical composition of the flows mixing at the confluence. Due to their capacity to sorb metals, it is important to identify the optimal conditions for removing metals from the aqueous phase, particularly arsenic, a contaminant frequently found in acid drainage. We studied a river confluence in the Lluta watershed, located in the arid Chilean Altiplano. We performed field measurements and laboratory studies to find optimal mixing ratio for arsenic sorption onto oxyhydroxide particles at the confluence between the Azufre (pH=2, As=2 mg/L) and the Caracarani river (pH=8, As<0.1 mg/L). As the contribution of the acidic stream increased, the concentration of Fe and Al in the solid phase reached a peak at different pHs. Although the optimal pH for As sorption was ~3, the overall maximum removal of As at the confluence, ocurred for pH~4. This is produced because optimal As sorption does not occur necessarily for the highest concentrations of particles being formed. We propose that fluvial confluences could be engineered to enhance the natural attenuation of contaminants. An analogy between confluences and coagulation-flocculation-sedimentation drinking water plants could be used to engineer such intervention.Acknowledgements: Proyecto Fondecyt 1130936 and Proyecto CONICYT FONDAP 15110020

    Introduccion. El test de comparacion perceptual de Salthouse (TCPS) evalua la velocidad de percepcion y de procesamiento. Aunque es un test ampliamente utilizado en neuropsicologia, no cuenta hasta la fecha con baremos normativos adaptados a la poblacion española. Objetivo. Normalizar y estandarizar el TCPS en poblacion española, teniendo en cuenta las caracteristicas sociodemograficas de nuestra sociedad. Sujetos y metodos. Este estudio se enmarca dentro del proyecto multicentrico Normacog, mediante el cual se administro el TCPS a 700 participantes, con edades comprendidas entre 18 y 90 años. Se analizo el efecto de variables sociodemograficas, como la edad, el nivel educativo o el sexo, sobre el rendimiento cognitivo en el TCPS, y se crearon los percentiles y las puntuaciones escalares ajustadas por edad y nivel educativo. Resultados. Los resultados mostraron un efecto significativo de la edad y del nivel educativo sobre las variables analizadas del TCPS (respuestas correctas y errores del TCPS-3 y TCPS-6), y la edad fue la que mayor porcentaje de varianza explicaba sobre el rendimiento del TCPS-3 (47%) y el TCPS-6 (45%). A mayor edad y menor nivel educativo, el numero de respuestas correctas disminuia y se realizaba mayor cantidad de errores. Conclusion. El presente estudio presenta por primera vez los baremos normativos del TCPS para poblacion española teniendo en cuenta las caracteristicas sociodemograficas del pais, que confirman la influencia de la edad y el nivel educativo sobre el rendimiento en el test. Como para el resto de pruebas del proyecto Normacog, se presentan las instrucciones de administracion y correccion del TCPS.

    Compendio El Reclutamiento y la Retención (R&R) de participantes es fundamental para el éxito de estudios y para el desarrollo de intervenciones preventivas. El R&R de participantes determina la validez y efectividad de estos programas. En este trabajo examinamos algunos de los factores que facilitan y dificultan el R&R en los proyectos preventivos y ofrecemos algunas alternativas para mejorar los índices de R&R. Realizamos dos estudios, en el primero administramos el Instrumento de Informatión, Motivatión y Conductas-Español (IIMC-E) a un grupo de 26 parejas heterosexuales (52 participantes). En el segundo, entrevistamos a 5 parejas VIH discordantes (10 participantes). Encontramos que el 75% de los/las participantes indicó que su trabajo era una de las principales barreras que dificultan la asistencia a las actividades. Otras barreras son las responsabilidades laborales y familiares. Encontramos que la principal barrera fue el miedo a la revelación del estado serlógico. Los principales facilitadores del R&R son la coordinación adecuada y el seguimiento telefónico ofrecido por parte del personal del proyecto. Concluimos que en el desarrollo e implantación de programas de prevención el investigador/a debe tomar en cuenta la adaptación de aspectos logísticos como la disponibilidad y las necesidades particulares de los/las participantes.

    Introducción: Los estudiantes universitarios se encuentran en un periodo crítico para el desarrollo de estilos de vida que tienen mucha importancia en su futura salud, ya que la influencia en el comportamiento alimentario de los compañeros, el consumo de alcohol, su situación económica y la habilidad para cocinar hacen que cambien sus hábitos de alimentación. Los pocos estudios en España sobre calidad de la dieta en este grupo de población reflejan mayoritariamente un inadecuado seguimiento del patrón mediterráneo. Objetivos: Caracterizar los hábitos alimentarios en una población de estudiantes universitarios y evaluar la calidad de su dieta. Métodos: Estudio transversal de una muestra de 80 estudiantes de la Facultad de Enfermería de Albacete (Universidad de Castilla-La Mancha). Los datos se recogieron mediante 9 recordatorios de 24 horas autoadministrados en tres periodos estacionales. El IAS y el MDS2 han sido usados como indicadores de la calidad de la dieta. En todas las pruebas el nivel de significación utilizado fue de 0,05. Resultados y discusión: La dieta de los estudiantes es ligeramente hipocalórica. La contribución de los macronutrientes a la energía total diaria la definen como hiperproteica (17%), pobre en hidratos de carbono, alrededor del 40%, casi duplica las recomendaciones de azúcares simples y es alta en grasa saturada y colesterol. La principal fuente de grasa son los alimentos cárnicos, mientras que el grupo del pescado sólo representa el 3,1%. La ingesta de cárnicos y lácteos supera ampliamente a la de poblaciones universitarias en otros países mediterráneos europeos. Más del 91% de los estudiantes se encuentra en una situación de «necesidad de cambios en la dieta» hacia patrones más saludables. La adherencia a la dieta mediterránea fue sólo del 53%.

    Introducción: la obesidad es un factor de riesgo asociado al infarto de miocardio aunque el índice cintura-cadera ha mostrado mayor poder predictivo.Objetivo: análisis antropométrico Receiver Operating Characteristic(ROC) en infartados para identificar la fuerza discriminatoria de mediciones, obesidad, ratios cintura-cadera, ratios cintura-talla e índice de conicidad.Métodos: estudio caso-control de infarto miocárdico en varones europeos. Ciento doce casos/112 controles de 30-74 años fueron reclutados. Se midieron: peso, talla, cintura, cintura umbilical y cadera. Se obtuvieron las áreas bajo la curva (ABC), las odds ratioy correlaciones de medidas e indicadores.Resultados: IMC [ABC: 0,686 (0,616-0,755); OR: 3,3], cintura [ABC: 0,734 (0,668-0,800); OR: 5,7], talla [ABC: 0,623 (0,550-0,696); OR: 2,3], cadera [ABC: 0,555 (0,479-0,631); OR: 1], cintura-cadera [ABC: 0,796 (0,737-0,855); OR: 9,9]; cintura umbilical-cadera [ABC:0,830 (0,775-0,885); OR: 5,5], cintura umbilical-talla [ABC: 0,788 (0,729-0,847); OR: 7,5]; conicidad [ABC: 0,795 (0,738-0,853); OR:9]. Cintura-talla y conicidad presentaron altas correlaciones de riesgo (todas r ≥ 0,85; p < 0,001).Conclusiones: cintura y talla son medidas con riesgo independiente asociado. La circunferencia de cadera no es discriminatoria. Obesidad e índices de cintura están asociados al infarto con diferente fuerza. La obesidad presenta una asociación débil. Los índices cintura-cadera presentan las mejores curvas ROC, pero sesgadas en su poder predictivo de riesgo. Cintura umbilical-talla y conicidad presentan alto poder discriminatorio y mejores correlaciones antropométricas de riesgo, por lo que se recomienda su uso en la identificación de la obesidad como factor asociado al infarto de miocardio y en todas las estrategias de promoción de la salud coronaria.

    The Tucupita Field has an area of 73,51 Km2, is located between the states of Monagas and Delta Amacuro, geologically is located at the greater Temblador area in the Eastern Venezuela Basin, where the Oficina Formation's sands represent the main hydrocarbons reservoirs. From the results of the seismic reprocessing realized by Fusion Petroleum Technologies, Inc., the structural model of this field was done as initial step to the geocellular model of the Oficina-40 Reservoir, which was defined as a Faulted Relay Ramp, where the normal faults are dominant with NE-SW orientation Introduction The Tucupita Field is a mature oilfield at the greater Temblador area, however most of the wells were completed in the upper sands, therefore the main study is focused in the geological characterization of the Oficina-40 Reservoir's lower sands, starting by the structural model Previous Studies 1.

    Objetivo: Cuantificar los problemas relacionados con los medicamentos (PRMs) mediante el establecimiento de un Programa Estratégico de Continuidad Asistencial (Programa e-Conecta-Concilia; e-CC) enfocado a la farmacoterapia de los pacientes pertenecientes a una Estructura Organizativa de Gestión Integrada, para garantizar la eficiencia, seguridad y trazabilidad terapéutica del paciente. Método: Estudio prospectivo de 8 meses de duración. Participaron en el proyecto 22 farmacéuticos de hospital y 12 de Atención Primaria. Se utilizó la historia clínica electrónica accesible a todos los niveles. Se llevaron a cabo las actuaciones necesarias para la creación de un procedimiento normalizado de trabajo (PNT) (creación de los grupos de trabajo, informática, puntos de encuentro) de coordinación entre farmacéuticos de diferentes niveles asistenciales con un sistema de comunicación común. Los grupos de trabajo constituidos por farmacéuticos de ambos niveles asistenciales establecieron los siguientes criterios de inclusión: pacientes con enfermedades crónicas y polimedicados, pacientes en los que se detectaba algún PRM, detección en Atención Primaria de un uso fuera de ficha técnica o discrepancias en la homologación de recetas sanitarias. Resultados: En el seno del Programa e-CC se unificaron las intervenciones y se identificaron discrepancias. Durante este proyecto se detectaron 245 problemas relacionados con los medicamentos, siendo los mayoritarios los de dosis, pauta o duración no adecuada (24%) y los que afectaban a los medicamentos del grupo B (33%), según la clasificación ATC. Conclusiones: La implantación de un PNT de Continuidad Asistencial entre farmacéuticos permitió detectar y resolver PRMs y discrepancias en la farmacoterapia de los pacientes, con un alto porcentaje de aceptación (84,1%) de las intervenciones.

    El proyecto de instrumentación de mayor importancia que ha tenido el Instituto de Astrofisica de Canarias en los últimos afios ha sido el diseflo y construcción del te1escopio IAC8O. Este requería del esfuerzo con junto en mec´nica, óptica y electrónica, lo que facilitó la estructuración y el crecimiento de los respectivos grupos de trabajo, que posteriormente se integraron en departamentos En su origen (1977), el telescopio IAC80 fue concebido como un sistema clásico tipo Cassegrain, con una razón focal F/i 1.3 para el sistema Casse grain y una razón focal F/20 para el sistema Coudé. Posteriormente, aunque se mantuvo la filosofia de que el sistema básico fuera el F/11.3, se consideró conveniente el diseño de secundarios para razones focales F/16 y F/32, y se eliminó el de F/20. Sin embargo, dada la importancia relativa que un foco estrictamente fotográfico tiene en un telescopio moderno, diseñado básicamente para fotometría fotoeléctrica y con un campo util mínimamente de 40 minutos de arco, se decídió Ilevar a cabo el diseño de un secundario F/8 con un sistema corrector de campo, pero que estuviera formado únicamente por lentes con superficies esféricas para que asl su construcción fuera posible en España ó en México. La creciente utilización de detectores bidimensionales para fines de investigación astron6mica y la viabilidad de que en un futuro cercano éstos tengan un área sensible cada vez mayor, hicieron atractiva la idea de tener diseñado un sistema corrector de campo para el foco primario (F/3), con un campo útil mínimo de un grado, y también con la limitante de que sus componentes tuvieron sólamente supérficies esféricas. Ambos diseños de los sis-temas correctores de campo se llevaron a cabo, en gran medida, como parte de un proyecto de colaboración e intercambio en el área de diseño y evaluación de sistemas ópticos.

    Desde el punto de vista tecnológico, el objetivo principal de este proyecto es desarrollar un cabezal de receptor en la frecuencia de 3.3 GHz, con una temperatura del sistema de 60 K y un ancho de banda de 140 MHz. El mismo será instalado en el foco primario de un reflector parabólico de 30 metros de diámetro que funcionará como radiómetro en el IAR. El receptor es del tipo polarimétrico, con lo cual permite la posibilidad de obtener las componentes de polarización lineal y circular. Para tal fin el cabezal constará de dos ramas receptoras que amplificarán la señal y la trasladarán a una frecuencia menor, (frecuencia intermedia), permitiendo de esa forma un mejor transporte de la señal a la sala de control para su posterior procesamiento. El receptor, además de tener características polarimétricas, podrá ser usado en el contínuo y en la línea, utilizando las ventajas observacionales y de procesamiento de señal que actualmente posee el IAR.

    The performance of an automatic speech recognizer is affected by training process (dependent on or independent of the speaker) and the size of the vocabulary. The language used in this study was the Spanish spoken in the city of Valdivia, Chile. A representative sample of 14 students and six professionals all natives of Valdivia (ten women and ten men) were used to complete the study. The sample ranged in age between 20 and 30 years old. Two systems were programmed based on the classical principles: digitalizing, end point detection, linear prediction coding, cepstral coefficients, dynamic time warping, and a final decision stage with a previous step of training: (i) one dependent speaker (15 words: five colors and ten numbers), (ii) one independent speaker (30 words: ten verbs, ten nouns, and ten adjectives). A simple didactical application, with options to choose colors, numbers and drawings of the verbs, nouns and adjectives, was designed to be used with a personal computer. In both programs, the tests carried out showed a tendency towards errors in short words with monosyllables like ``flor,'' and ``sol.'' The best results were obtained in words with three syllables like ``disparar'' and ``mojado.'' [Work supported by Proyecto DID UACh N S-200278.

Seventy-two caimans (20-day-old) from Proyecto Yacaré (Gob. Santa Fe/MUPCN) were used. Two groups were exposed for 2 months to different concentrations of RU (11 or 21 mg/L; taking into account the concentration recommended for its application in the field), while one group was maintained as control. The RU concentration was progressively decreased through the exposure period to simulate glyphosate degradation in water. Animals were measured and weighed at the beginning and end of the experiment, and blood samples taken after exposure to determine total and differential white blood cell (WBC) counts as well as total protein concentration (TPC), and for performing protein electrophoresis. The results showed that, compared against control hosts, there was a decrease in WBC counts, a higher percentage of heterophils, a higher TPC (with a low percentage of F2 protein fraction), and a negative effect on growth in the young caimans exposed to RU. These results demonstrate that in vivo exposure to RU induced alterations in the selected immune parameters, plasma proteins, and growth of caimans, thereby providing relevant information about the effects of this type of pesticide in this important species in the Argentinian wetlands.

    RR Lyrae variables are the cornerstone of the Population II distance scale, and yet our knowledge of the RR Lyrae variable star content in Galactic globular clusters is now known to be surprisingly incomplete. In the present paper, we present our new results in this area. Highlights of our work includes: i) The discovery of a vast number of variable stars in M62 (NGC 6266), making it one of the three most RR Lyrae-rich globular clusters known, and also placing it as Oosterhoff type I in spite of a blue horizontal branch morphology; ii) The determination of light curves and Oosterhoff types for globular clusters associated with the Sagittarius dSph galaxy, including NGC 5634, Arp 2, and Terzan 8; iii) A reassessment of the variable star content in the moderately metal-rich globular clusters M69 and NGC 6304; iv) The first theoretical calibration of the RR Lyrae period-luminosity-metallicity relation in I, J, and H, as well as an updated calibration of the K-band relation---along with comparisons against the empirical data, particularly in I. This project was supported in part by Proyecto Fondecyt Regular 1030954.

    The PISCO'94 (Proyecto de Investigatión Sismológica de la Cordillera Occidental, 1994) seismological network of 31 digital broad band and short-period three-component seismometers was deployed in northern Chile between the Coastal Cordillera and the Western Cordillera. More than 5300 local seismic events were observed in a 100 day period. A subset of high-quality P and S arrival time data was used to invert simultaneously for hypocenters and velocity structure. Additional data from two other networks in the region could be included. The velocity models show a number of prominent anomalies, outlining an extremely thickened crust (about 70 km) beneath the forearc region, an anomalous crustal structure beneath the recent magmatic arc (Western Cordillera) characterized by very low velocities, and a high-velocity slab. A region of an increased Vp/Vs ratio has been found directly above the Wadati-Benioff zone, which might be caused by hydration processes. A zone of lower than average velocities and a high Vp/Vs ratio might correspond to the asthenospheric wedge. The upper edge of the Wadati-Benioff zone is sharply defined by intermediate depth hypocenters, while evidence for a double seismic zone can hardly be seen. Crustal events between the Precordillera and the Western Cordillera have been observed for the first time and are mainly located in the vicinity of the Salar de Atacama down to depths of about 40 km.

    Lucky imaging techniques implemented by the FastCam group (see http://www.iac.es/proyecto/fastcam/) at the Instituto de Astrofisica de Canarias have demonstrated its ability to obtain spectacular diffraction limited images in telescopes ranging from 1 to 4.2 m in visible wavelengths (mainly in the I band), at the expense of using only a small percentage of the available images. This work presents the development of a real-time processor, FPGA-based, capable of performing all the required processing involved in the lucky imaging technique: Bias and flat-field correction, quality evaluation of images, quality threshold for image selection, image recentering and accumulation, and finally sending through Gigabit Ethernet both raw and processed images to a PC computer. Furthermore, a real time display is generated directly from FPGA showing both types of images, plus a histogram of the computed quality values and the threshold used. All processes can co-exist physically located in separated places inside the FPGA, using its natural parallel approach, and can easily handle the 512x512 pixels at 30 fps found at the sensor camera output (an Andor Ixon+ DU-897ECSO EMCCD). Flexibility and parallel processing features of the reconfigurable logic have been used to implement a novel imaging strategy for segmented-mirror telescopes, allowing separate evaluation of every segment and posterior accumulation to achieve the resolution limit of a single segment with the integration capability of the full primary mirror.

    FastCam is an instrument jointly developed by the Instituto de Astrofísica de Canarias (IAC) and the Universidad Politécnica de Cartagena (UPCT), designed to obtain high spatial resolution images in the optical wavelength range from ground-based telescopes (http://www.iac.es/proyecto/fastcam and http://www.iac.es/telescopes/Manuales/manualfastcam.pdf). The instrument is equipped with a very low noise and very fast readout speed EMCCD camera which provides short exposure images to an FPGA-based processor which performs the selection, recenterg and combination of images in real-time (applying Lucky Imaging techniques) to provide diffraction limited resolution images in 1-4 m class telescopes from 500 to 1100 nm. IDOM has contributed to this new state-of-the-art instrument with the design of an optomechanical system conceived to maximize the image scale stability of the system for astrometry. The combination of aluminum plates, carbon fiber (CFRP) rods and stainless steel mounts in the optical bench defines an athermalized and stiff design to meet the requirements of thermal and mechanical stability. This work has been done with the support of the Aerospace Subprogramme of the Spanish Centre for the Development of Industrial Technology (CDTI) and the INTEK programme of the Basque Development Agency (SPRI).

  7. The man swimming against the stream knows the strength of it: Hydraulics and social relations in an Argentinean irrigation system

    NASA Astrophysics Data System (ADS)

    Ertsen, Maurits W.; Nooijen, Ronald van

    In this paper we discuss hydraulic behavior of irrigation infrastructure within a context of spatially distributed power relations in an Argentinean irrigation system. In the Río Dulce basin, the irrigation area known as the Proyecto Río Dulce (PRD, command area 350,000 hectares) is the main irrigated area. An interesting characteristic of the PRD is that the larger landowners are mainly situated in tail end areas. Despite this potentially disadvantageous position, downstream farmers do not encounter problems in terms of water availability. This should not be regarded as self-evident: the hydraulic properties of the canals induce a need for downstream farmers to take deliberate action to ensure proper water delivery to their farms. When upstream farmers do not irrigate, too much water can flow downstream; when they irrigate too much, or manipulate cross regulators, downstream water scarcity can be the result; when canals are not maintained, extensive plant growth will increase hydraulic resistance and decrease discharges. It is not a coincidence that the downstream farmers invest heavily in canal operation and maintenance. These investments appear to be appropriate, as larger farmers tend to irrigate much more on average, compared to the smaller farmers upstream. The Argentinean case brings up issues on the structuring effects of irrigation systems, which need stronger theoretical understanding.

    Background Latinas have high overall breastfeeding initiation rates, yet Puerto Ricans have among the lowest exclusive breastfeeding rates. This study sought to determine if acculturation was associated with intent to breastfeed in a predominantly Puerto Rican population. Methods A cohort of Latina women were enrolled in Proyecto Buena Salud, and provided information on infant feeding intent (N=1323). Acculturation was assessed via the Psychological Acculturation Scale (PAS), language preference and generation in the US. Results Increasing acculturation as measured by English language preference (aOR 0.61, 95% CI 0.42-0.88) and second/third generation in the US (aOR 0.70, 95% 0.52-0.95) was inversely associated with odds of intending to exclusively breastfeed. Similarly, women with higher levels of acculturation as measured by the PAS (aOR 0.67, 95% CI 0.45-0.99), English language preference (aOR 0.48, 95% CI 0.33-0.70) and second or third generation in the US (aOR 0.42, 95% CI 0.31-0.58) were less likely to report intent to combination feed as compared to women with lower acculturation. Conclusions Acculturation was inversely associated with intent to exclusively breastfeed as well as intent to combination feed in this predominantly Puerto Rican sample. PMID:26554873

    Anxiety in pregnancy has been associated with adverse birth outcomes. Relatively few studies have investigated how acculturation affects mental health in pregnancy among Latinas. The goal of this study was to determine if acculturation was associated with anxiety over the course of pregnancy in a sample of predominantly Puerto Rican women. Women were recruited in pregnancy for participation in Proyecto Buena Salud, a prospective cohort study of Latina women (n = 1412). Acculturation was measured via the Psychological Acculturation Scale (PAS), language preference and generation in the USA. Anxiety was measured using the State-Trait Anxiety Instrument. Linear and logistic multivariable regressions were used to investigate associations. After adjustment, women with bicultural identification had significantly lower trait anxiety scores in early pregnancy (β = -3.62, SE = 1.1, p < 0.001) than low acculturated women. Women with higher levels of acculturation as indicated by English-language preference (β = 1.41, SE = 0.7, p = 0.04) and second or third generation in the USA had significantly higher trait anxiety scores in early pregnancy (β = 1.83, SE = 0.6, p < 0.01). Bicultural psychological acculturation was associated with lower trait anxiety in early pregnancy, while English-language preference and higher generation in the USA were associated with higher trait anxiety in early pregnancy.

    The objective of this study was to analyze health agents' perception of self-collecting of samples for HPV testing among women and the degree of agreement by the agents to incorporate this approach into their daily tasks. A self-administered questionnaire was applied to 127/191 health agents that participated in the EMA Project (Proyecto Evaluación Modalidad Autotoma) in the province of Jujuy, Argentina, in 2012-2013. The health agents with and without the experience of offering self-collected sampling expressed a high degree of agreement towards adoption of the strategy (78.7%), given its potential to prevent cervical cancer and its contribution to health care for the women under their coverage. However, the health agents identified the extra work and problems linking to the formal health system as the main barriers to offering this modality in the future. The study found that self-collecting of samples is a practice that can be adopted by health agents in the province of Jujuy, but that it should be accompanied by support measures from the formal health system.

  12. A Millenium of Great, and Perhaps Lesser, Earthquakes Recorded by Unusual Landslide and Tsunami Deposits in Chiloe, South-Central Chile

    A stratigraphic sequence at Cocotue Bay, Chiloe Is., south-central Chile, containing both earthquake-triggered debris flows and tsunami deposits, yields an earthquake history that likely includes the giant earthquakes and tsunamis inferred previously from a combination of geology, ecology, and written records in south-central Chile (AD ~1000, ~1300, 1575 and 1960). However, the Cocotue sequence also contains evidence for at least four additional earthquakes and tsunamis that are intermediate in age and perhaps lesser in size. The most recent of the additional earthquakes recorded at Cocotue probably corresponds to the poorly understood Chilean earthquake and associated trans-Pacific tsunami of 1837. The tsunami, though small on the Chilean coast, ran as high as 6 m in Hawaii and flooded fields in Japan. At Cocotue, the 1837 earthquake, like other three earlier events, is probably represented by both a debris-flow deposit and a tsunami deposit. To study the sedimentary record of intermediate and lesser events is important because this is the more probable kind of event to occur in the near future of south-central Chile.

    Chronic obstructive pulmonary disease (COPD) is now a major public health concern; deaths attributable to COPD in Latin America have increased by 65.0% in the last decade. This study was aimed at evaluating COPD prevalence and associated factors in adults (> 40 years) living in Greater Metropolitan São Paulo, Brazil. The study is part of the Proyecto Latinoamericano de Investigación en Obstrucción Pulmonar (The PLATINO Project), a multi-center survey on COPD burden in Latin America, with São Paulo as the first center where the project has been carried out. A population-based sample was selected in multiple stages. Spirometry tests were performed in each subject pre- and post-bronchodilator and COPD was mainly defined as the ratio of forced expiratory volume to forced vital capacity below 70.0% (fixed ratio definition). Other spirometric criteria were also used for the diagnosis of COPD. COPD prevalence was 15.8% (95%CI: 13.5-18.1) using the fixed ratio definition. COPD was positively associated with age and smoking and inversely with body mass index. Utilization of different COPD spirometry criteria resulted in different percentages of COPD, but similar associated factors.

  14. Seismic signals from Lascar Volcano

    Lascar, the most active volcano in northern Chile, lies near the center of the region studied during the Proyecto de Investigación Sismológica de la Cordillera Occidental 94 (PISCO '94). Its largest historical eruption occurred on 19 April 1993. By the time of the PISCO '94 deployment, its activity consisted mainly of a plume of water vapor and SO 2. In April and May 1994, three short-period, three-component seismometers were placed on the flanks of the volcano, augmenting the broadband seismometer located on the NW flank of the volcano during the entire deployment. In addition to the usual seismic signals recorded at volcanoes, Lascar produced two unique tremor types: Rapid-fire tremor and harmonic tremor. Rapid-fire tremor appears to be a sequence of very similar, but independent, "impulsive" events with a large range of amplitudes. Harmonic tremor, on the other hand, is a continuous, cyclic signal lasting several hours. It is characterized by a spectrum with peaks at a fundamental frequency and its integer multiples. Both types of tremor seem to be generated by movement of fluids in the volcano, most probably water, steam or gas.

    The objectives of this study were, first, to explore the prevalence of aggressors with lifetime intimate partner violence (IPV) among patients in the Proyecto Hombre of Navarra (Spain) addiction treatment programme; and second, to know the specific and differential characteristics of patients presenting IPV as aggressors. A sample of 162 patients (119 men and 43 women) was assessed. Data on socio-demographic and substance consumption characteristics, IPV variables, psychopathological symptoms, and personality variables were obtained. The profiles of patients in addiction treatment with and without a history of violence towards their partners were compared. The results showed that 33.6% of people in treatment for addiction had committed violence against their partners. This prevalence was significantly higher (χ(2)  = 15.6, p < .001) in women (63.3%) than in men (24.2%). In the 98.4% of the cases the IPV was bidirectional. Patients with a history of IPV perpetration showed greater severity in substance consumption variables, psychopathological symptoms, and personality traits. Gender, the family scale on the European version of the Addiction Severity Index (EuropASI), and the aggressive-sadistic scale on the Millon Clinical Multiaxial Inventory (MCMI-III) were the main variables related to the presence of IPV as aggressors. There was a differential profile in patients with IPV perpetration, showing more psychopathological and personality symptoms. Moreover, in this study being a woman was one of the main predictors of committing IPV. © American Academy of Addiction Psychiatry.

    Superconductor/ferromagnet heterostructures are currently a subject of strong research due to novel phenomena resulting from the proximity effect. Among the most investigated ones are the oscillations of the critical temperature as function of the ferromagnet thickness. The oscillatory behavior of Tc is theoretically explained as to be result of the generation of the FFLO (Fulde-Ferrel-Larkin-Ovchinnikov) state of Cooper pairs under the presence of the exchange field of the ferromagnet. With the advancement of experimental techniques for S/F bilayers growth new questions regarding the effect of the interface transparency can to be addressed. For instance the influence of the interface roughness on the proximity effect. For studying this phenomenon Nb/Co and Nb/Cu/Co samples were sputtered on SiO2 substrates with different roughness. Characterization of these samples show a significant variation of Tc with the interface roughness. This results point towards a possible relationship between transparency and roughness of the interface. Proyecto Semilla Facultad de Ciencias Universidad de los Andes.

    The presence of ancient Maya shrines in caves serves as unequivocal evidence for the ritual appropriation of these subterranean spaces and their significance with respect to Maya religious practice. Detailed study of the miniature masonry temples and altar features in the caves of Quintana Roo, Mexico reveals a strong stylistic and likely functional correspondence between these structures and their terrestrial counterparts at Postclassic sites. The Proyecto Arquitectura Subterranea de Quintana Roo (coordinated by the Center of Interdisciplinary Science for Art, Architecture, and Archaeology, or CISA3, at the University of California, San Diego and in collaboration with the Instituto Nacional de Antropologia e Historia in Mexico) is conducting a survey and program of digital documentation of both the pristine and impacted cave shrines of the region. Once an area is developed and populated, and access is opened to caves containing ancient architectural features, they are soon vandalized - often resulting in the complete obliteration of these rare miniature buildings and their diagnostic architectural elements. This emergent situation necessitates the use of rapid reality-capture tools; however, the physical challenges of working in caves requires researchers of adapt increasingly common architectural documentation methodologies to more adverse field conditions.

    In this paper, the effectiveness of the treatment program developed by Proyecto Hombre ('Project Mankind') in Asturias, Spain, is evaluated. In a long-term follow-up (range from 73 days to 8 years) with a sample of 249 subjects, the results obtained by subjects completing the treatment (194) were compared with pre-treatment results and with those of the group that dropped out (55). The measurements used were relapses in illegal drugs, alcohol, changes in family situation, educational level, employment, criminal involvement and state of health. External validation of self-report measures given in the questionnaire was carried out. Findings support the effectiveness of the treatment in all measures and the validity of self-report items. Relapse rate in 'treatment-completed' group was 10.3%, whilst in the non-completers group it reached 63.6% (significant difference, p < 0.001). Relapses of non-completers were more severe, occurred sooner after leaving the program (they stayed abstinent for shorter periods) and lasted longer than those of subjects completing the treatment.

    Introduccion. El desarrollo que han tenido las neurociencias ha avanzado de una manera rapida y espectacular. Puntos clave para ello son la introduccion de las tecnicas de neuroimagen funcional y el empuje del proyecto 'decada del cerebro'. Este desarrollo tambien ha permitido que surjan nuevas disciplinas como la neuroetica. Desarrollo. Quienes han trabajado en neuroetica pueden dividirse en tres grupos (neurorreduccionistas, neuroescepticos y neurocriticos), y cada grupo tiene diferentes posturas de lo que es la neuroetica, con varios alcances y limitaciones en sus propuestas. Conclusiones. La neuroetica es una disciplina que antes del año 2002 se entiende en exclusiva como una etica de la neurociencia (una rama de la bioetica) y, a partir de esa fecha, se entiende tambien como una neurociencia de la etica (una nueva disciplina). El neurorreduccionismo propone que toda la vida etica tiene una base cerebral que determina los actos eticos, el neuroescepticismo argumenta que no se puede considerar la neurociencia como una funcion normativa y el neurocriticismo considera que los avances neurocientificos no se pueden ignorar y se deben tomar en cuenta de algun modo para la elaboracion de las teorias eticas.

    To describe the characteristics, working conditions, and occupational health situation of immigrant workers in Spain through key informants. We performed a qualitative, exploratory and descriptive study using indepth interviews carried out in 2006. Organizations and associations working with immigrant collectives in Alicante, Barcelona, Huelva, Madrid and Valencia were identified and the most representative and accessible entities in each location were selected. Fortythree interviews were performed with key informants from 34 different organisms. A narrative content analysis was performed. Informants described difficulties in having health problems recognized as workrelated, due to irregular and precarious employment, employers' and insurance companies' reluctance, and immigrants' lack of knowledge. Informants coincided in reporting that the occupational risks for immigrant workers did not differ from those affecting Spanish workers in the same occupations and circumstances. However, exposure to occupational risks was exacerbated in immigrants because of their greater presence in unqualified jobs and their economic need to prolong working hours. Immigrants had little knowledge of their occupational health and safetyrelated rights, although some informants detected an increase in empowerment in this area, mostly through greater participation in trade unions. This first step allowed us to identify some of the general factors influencing the health and safety of immigrant workers in Spain. This information will be used in a longterm, ongoing research project [Project Immigration, Work and Health (Proyecto Inmigración, Trabajo y Salud [ITSAL]), which aims to evaluate occupational health problems in inmigrants working in Spain through both qualitative and quantitative methods.

    Regional registers of patients with acute myocardial infarction are scarce in Spain. The PRIMVAC register (Proyecto de Registro de Infarto agudo de Miocardio de Valencia, Alicante y Castellón) was initiated to obtain updated information on the management of these patients in the Valencia Autonomous Community. Data of the first twelve months of the register are presented. The 17 participating hospitals cover 2,833,938 inhabitants. Demographic, clinical, procedural and outcome data as well as predictive variables of mortality were analysed in the patients with acute myocardial infarction during their stay in the coronary care units from 1 December 1994 to 30 November 1995. During 12 months, 2,377 patients were included. Mean age was 65.3 years (SD 11.9) and 23.2% were female. Left ventricular failure was present in 39.8%. Thrombolytic therapy was applied in 42.1% with a median time delay of 195 min from chest pain onset. This time was longer in the women (250 min) and in the elderly (210 min). The in-coronary-care-unit-mortality rate was 13.9%. Age, female gender, diabetes, previous myocardial infarction, Q wave and right ventricular infarction independently predicted increased early mortality. Present data show the feasibility of an acute myocardial infarction register in the Valencia Autonomous Community. Although an acceptable level of thrombolysis has been reached, the mortality rate is still high. The long delay in initiating thrombolysis, particularly in female and elderly patients is remarkable.

Results After adjustment, women with bicultural identification had significantly lower trait anxiety scores in early pregnancy (beta −3.62, SE 1.1, p<0.001) than low acculturated women. Women with higher levels of acculturation as indicated by English language preference (β=1.41, SE 0.7, p=0.04) and second or third generation in the US had significantly higher trait anxiety scores in early pregnancy (β=1.83, SE 0.6, p<.01). Conclusions Bicultural psychological acculturation was associated with lower trait anxiety in early pregnancy, while English language preference and higher generation in the US were associated with higher trait anxiety in early pregnancy.

    Administrative personnel from healthcare centers are an important opinion group given their direct relationship to patients and the general public. The objective of this study was to analyze the attitudes of administrative personnel in Spanish and Mexican healthcare centers toward various kinds of donation. A random selection of 418 administrative staff from 32 primary care centers and 9 hospitals in Spain and Mexico ("Proyecto Donante, Murcia") used a validated questionnaire to explore attitudes. Most (76%) respondents favored deceased donation. Mexican workers had the most favorable attitude (P<.001). Factors influencing this attitude (P<.05) were as follows: type of healthcare center, clinical service, personal experience of organ donation and transplantation (ODT), attitude toward living donation, attitude toward the donation of a family member's organs, discussion of ODT, partner's attitude toward ODT, participation in pro-social activities, and variables related to attitudes toward the body. Most respondents (89%) favored related living kidney donation (LKD) and 87% favored living liver donation (LLD). Mexican respondents showed the most favorable attitudes (P<.05). Factors influencing this attitude (P<.05) were as follows: personal experience of ODT, belief that a transplant is needed, willingness to accept a living organ, family discussion about ODT, partner's attitude about the matter, and respondent's awareness of the view of his or her religion toward ODT. Attitudes toward deceased organ donation were not favorable among administrative personnel from Spanish compared with Mexican centers, although attitudes toward LKD and LLD were favorable in both countries.

    During FY 97, 152 MUREP education and training projects were conducted at OMU institutions. The institutions conducted precollege and bridge programs, education partnerships with other universities and industry, NRTS, teacher training, and graduate and/or PI undergraduate programs. These programs reached a total of 23,748 participants, with the predominant number at the precollege level and achieved major goals of heightening students' interest and awareness of career opportunities in MSET fields, and exposing students to the NASA mission, research and advanced technology through role models, mentors, and participation in research and other educational activities. Also in FY 1997, NASA continued a very meaningful relationship with the Hispanic Association of Colleges students and Universities (HACU) through Proyecto Access, a consortium through which HACU links seven HSI's together to conduct 8-week summer programs. OMU Institutions reported 4,334 high school student in NASA programs and 3,404 of those students selected college preparatory MSET courses. Three hundred and forty-nine (349) graduated from high school, 343 enrolled in college, and 199 selected MSET majors. There were 130 high school graduates (bridge students) in NASA programs, 57 of whom successfully completed their freshman year. There were 307 teachers in teacher programs and 48 teachers received certificates. Of the 389 undergraduate students, 75 received under graduate degrees, and eight students are employed in a NASA-related field.

    Parental depression is a major risk factor in child development. Growing research suggests parenting programs can positively impact parental depressive symptoms, although the specific mechanisms that explain these effects are unknown. The current study examined parenting mediated effects of a parenting program on mothers' and fathers' depressive symptoms, as well as the role of child behavior in linking parenting to reductions in depressive symptoms. The study samples included 494 mothers and 288 fathers of Mexican origin adolescents who participated in a randomized trial of the Bridges to High School Program/Proyecto Puentes a la Secundaria, a universal prevention and promotion intervention that included parent training but did not directly target parental depressive symptoms. Parenting mediator models tested program effects on parental depressive symptoms through changes in harsh and supportive parenting. Results showed a significant indirect intervention effect on maternal depressive symptoms through changes in mothers' harsh parenting. Next, child behavior models revealed a partial mediation effect of harsh parenting and a full mediation effect of supportive parenting on maternal depressive symptoms through mothers' reports of child externalizing symptoms. Indirect effects of fathers' harsh and supportive parenting on paternal depressive symptoms were also found through fathers' reports of child behavior.

    To analyze the attitude of nursing personnel about organ donation and transplantation in hospitals in Spain and Latin America, and factors that affect this attitude. Data were selected from 12 hospitals and 32 primary care centers participating in an international study (Proyecto Donante, Murcia) in 4 countries including Spain (n = 650), Mexico (n = 428), Cuba (n = 89), and Costa Rica (n = 27). The sample was random and stratified by type of service among nursing personnel (n = 1194). Attitude was evaluated using a psychosocial questionnaire. Of nursing personnel surveyed, 77% (n = 922) were in favor of organ donation. No differences were found according to whether they were directly involved in transplantation-related services (P < .05). Attitude in favor of organ donation varied between countries: 92% in Cuba, 85% in Costa Rica, 80% in Mexico, and 73% in Spain (P < .001) This attitude was also related to donation of a family member's organs (P < .001), having discussed organ donation and transplantation within the family (P < .001), the concept of brain death (P < .001), fear of body mutilation (P < .001), and manipulation of the body after death (P = .001). Attitude toward deceased organ donation among nurses varies between countries. There is a discrepancy between those in favor vs actual donation rates in countries and work centers. These fears may become worse when donation is seen as common in daily clinical practice.

    When a child is diagnosed with a food allergy, prevention and patient education are the key interventions for maintaining the child's health and quality of life and that of his or her whole family. However, health education activities for the families of children with food allergies are very limited, and most of these activities have not been evaluated. Therefore, the objectives of the present study were to develop an educational programme, to empower its participants through workshops, and to evaluate its results. Several types of educational materials were created specifically for the programme, called "Proyecto CESA" ("STOP-FAR Project: Stop Food-Induced Allergic Reactions"). The programme was carried out in seven Spanish cities and was attended by parents and caregivers. The workshops were led by physicians specialising in allergies and by expert patients. Afterwards, participant learning and satisfaction were evaluated based on questionnaires that were completed both before and after the workshops. A significant improvement was observed in 29 items out of 40 (McNemar's test). Participant satisfaction with the programme was also very high: 90% rated the course between 8 and 10 points out of a possible 10 (41% rated it as a 10). The face-to-face workshops, which included utilisation of educational materials, had positive results in terms of learning as well as in levels of satisfaction in participating families.

    Despite continued high HIV risk among Hispanic men who have sex with men (HMSM), culturally tailored, theoretically based interventions have yet to be developed and tested. As a first step toward intervention development, we collected quantitative and qualitative data on sociocultural and psychological factors associated with drug use and risky sex among 566 HMSM recruited from community and Internet venues. Participants reported high rates of drug use (43%), unprotected anal sex (45%), and multiple sex partners (median 4) in the past 6 months. In multivariate analyses, use of drugs was associated with HIV seropositivity, less orientation to the Hispanic community, stronger attachment to the gay community, lower levels of homophobia, higher numbers of sex partners and more unprotected anal sex. The need for acceptance and desire to please partners emerged as core drivers of HIV risk in the qualitative data. Findings were used to guide development of Proyecto SOL, a theoretically grounded intervention that targets core determinants of HIV risk, builds on protective cultural influences, and strengthens positive social connections.

    The behavior of a phase-locked dual frequency capacitively coupled rf discharges (2f-CCRF) in the background of multi-component plasma is experimentally studied by rf current-voltage measurements and optical emission spectroscopy (OES). The multi-component plasma is produced by adding hydrogen to the argon CCRF discharge. Variation of experimental parameters, like working pressure, low frequency (LF) and high frequency (HF) rf power indicate significant changes in the electron density and temperature as well as the DC self-bias developed on the power electrode. It is observed that the electron density decreases as the percentage of hydrogen increases in the argon plasma while the electron temperature follows opposite trend. An analytical sheath model for the 2f-CCRF discharge in the background of multi-component plasma is developed and its prediction on the observed variation of DC self-bias is well agreed with the experimental observations.

    We used SWOT-AHP (strengths, weaknesses, opportunities and threats-analytical hierarchy process) technique to measure perceptions of four stakeholder groups: employees, local promoters, community leaders and end-users, about a nontraditional cookstove (NTCS) in Honduras. These stakeholder groups are part of an ongoing NTCS dissemination project led by Proyecto Mirador. We found that all stakeholder groups have a positive perception about the existing NTCS. Employees and local promoters stakeholder groups share similar perceptions. Smokeless cooking was selected as a prime strength, closely followed by reduction in forest logging and greenhouse gas emissions by all stakeholder groups. Availability of financial resources and responsible management were identified as crucial opportunities. Time spent in wood preparation and NTCS maintenance were identified as principal weaknesses. A long waiting time between a request and installation of NTCS and the risk of losing existing financial resources were acknowledged as major threats. Design improvements that can reduce maintenance and wood preparation time, a secure long-term source of funding through a market mechanism or direct/indirect government involvement, and early execution of pending orders will help in increasing adoption of NTCSs in rural Honduras.

    La comunicación entre padres/madres y adolescentes sobre el tema de la sexualidad es importante para el desarrollo de la salud de personas jóvenes. Dicha comunicación puede verse negativamente impactada por actitudes estigmatizantes hacia el tema del VIH/SIDA. El objetivo de este estudio fue identificar actitudes estigmatizantes hacia el VIH/SIDA entre padres/madres y adolescentes puertorriqueños/as. Este esfuerzo es parte del Proyecto Cuídalos, dirigido a probar una intervención en formato electrónico que busca aumentar la comunicación sobre sexualidad y salud entre padres/madres y adolescentes mediante un diseño experimental con 458 diadas de padres/madres y adolescentes de 13 a 17 años. Para propósitos de este artículo reportamos estadísticas descriptivas sobre estigma hacia el VIH/SIDA con la información recopilada en la medición basal. Tanto adultos/as como adolescentes mostraron actitudes estigmatizantes hacia el VIH/SIDA. A la luz de los resultados es necesario continuar desarrollando intervenciones para la reducción de estigma en esta población. Los/as padres/madres pueden ser un recurso invaluable para reducir el estigma en los/as jóvenes, y prevenir conductas sexuales de riesgo e infecciones. PMID:27099649

    Latinas have high overall breastfeeding initiation rates, yet Puerto Ricans have among the lowest exclusive breastfeeding rates. This study sought to determine if acculturation was associated with intent to breastfeed in a predominantly Puerto Rican population. A cohort of Latina women were enrolled in Proyecto Buena Salud, and provided information on infant feeding intent (n = 1,323). Acculturation was assessed via the Psychological Acculturation Scale (PAS), language preference, and generation in the United States. Increasing acculturation as measured by English language preference (aOR 0.61 [95% CI 0.42-0.88]) and second or third generation in the United States (aOR 0.70 [95% CI 0.52-0.95)] was inversely associated with odds of intending to exclusively breastfeed. Similarly, women with higher levels of acculturation as measured by the PAS (aOR 0.67 [95% CI 0.45-0.99]), English language preference (aOR 0.48 [95% CI 0.33-0.70]) and second or third generation in the United States (aOR 0.42 [95% CI 0.31-0.58]) were less likely to report intent to combination feed as compared with women with lower acculturation. Acculturation was inversely associated with intent to exclusively breastfeed and intent to combination feed in this predominantly Puerto Rican sample. © 2015 Wiley Periodicals, Inc.

    En principio, este proyecto intenta lograr el mayor aprovechamiento posible del instrumental que se dispone, buscando la manera de optimizar y hacer más eficiente el servicio que brinda el CASLEO a la comunidad astronómica. El mismo consiste en utilizar dispositivos ya existentes en el telescopio, y darle una utilidad. Tal es el caso del camino óptico destinado al foco Coude. Si tenemos en cuenta que disponemos de un tercer espejo Coude, con todos sus mecanismos automatizados, (actualmente sin uso), una distancia apropiada del plano focal, el espacio y el lugar físico necesario para instalar un periférico, es posible la habilitación de un foco Nasmyth en el telescopio 2,15mts. El hecho de contar con este nuevo foco, redundará en importantes beneficios. En primer lugar, posibilitará la observación, casi simultánea, con dos instrumentos. Otro aspecto a tener en cuenta, es que disminuirá el frecuente cambio del instrumental periférico, motivo este que degrada su ideal puesta a punto. Por último, también de interés, es de destacar su escaso costo de ejecución.

  18. Magnetostatic modes in ferromagnetic samples with inhomogeneous internal fields

    2015-03-01

    Magnetostatic modes in ferromagnetic samples are very well characterized and understood in samples with uniform internal magnetic fields. More recently interest has shifted to the study of magnetization modes in ferromagnetic samples with inhomogeneous internal fields. The present work shows that under the magnetostatic approximation and for samples of arbitrary shape and/or arbitrary inhomogeneous internal magnetic fields the modes can be classified as elliptic or hyperbolic, and their associated frequency spectrum can be delimited. This results from the analysis of the character of the second order partial differential equation for the magnetostatic potential under these general conditions. In general, a sample with an inhomogeneous internal field and at a given frequency, may have regions of elliptic and hyperbolic character separated by a boundary. In the elliptic regions the magnetostatic modes have a smooth monotonic character (generally decaying form the surfaces (a ``tunneling'' behavior)) and in hyperbolic regions an oscillatory wave-like character. A simple local criterion distinguishes hyperbolic from elliptic regions: the sign of a susceptibility parameter. This study shows that one may control to some extent magnetostatic modes via external fields or geometry.

    Anxiety has negative effects on the cognitive performance and psychosocial adjustment of elderly people. Given the high prevalence of anxiety symptoms in patients suffering from cognitive impairment, it has been suggested that these symptoms may be an early marker of dementia. The State-Trait Anxiety Inventory (STAI) is one of the most widely-used scales for evaluating anxiety in elderly people. However, inasmuch as the STAI may be difficult to apply to older people, having a short form of it would be desirable. The participants comprised 489 community-dwelling individuals aged 68 years and over. All of them were volunteers in a longitudinal study for early detection of Alzheimer' Disease (Proyecto Vallecas). The full sample was divided in two homogeneous subgroups: Group A, used to reduce the number of items and response options, and Group B, the group used to determine the psychometric properties of the new short form (STAIr). A dichotomous Rasch model was used to obtain the STAIr. No statistically significant differences for STAIr scores were found with respect to sociodemographic variables. Psychometric properties and normative data were obtained for the new short version. The STAIr is composed of 13 items and data fits the model well. Since it is short and easy to apply to elderly people, STAIr will be very useful in clinical and research settings. Copyright © 2013 Sociedad Española de Neurología.

    Las manifestaciones extranglandulares y desórdenes linfoproliferativos son complicaciones que pueden comprometer el curso benigno del Síndrome de Sjögren Primario (SSp). Existen escasos marcadores serológicos con comprobada utilidad para predecirlas y/o diagnosticarlas. Objetivos: Evaluar la utilidad de Beta2microglobulina (β2m) en pacientes con SSp y correlacionarlos con parámetros séricos predictivos de manifestaciones extraglandulares y enfermedades linfoproliferativas (Factor Reumatoideo (FR), Inmunoglobulinas séricas (Igs), C3 y C4). Materiales y métodos: Se realizó una revisión retrospectiva de historias clínicas de pacientes que consultaron en la Unidad de Reumatología del Hospital Córdoba desde enero de 2010 a octubre 2013 y que fueron derivados a la Sección de Inmunología del Servicio de Bioquímica para la determinación de pruebas de laboratorio . Los pacientes fueron clasificados de acuerdo a los Criterios Diagnósticos de patologías autoinmunes en pacientes con diagnóstico de SSp según el Grupo Consenso Americano-Europeo, otras enfermedades autoinmunes y los controles sanos. Se estudiaron las IgG, IgA e IgM, factores del complemento C3, C4 séricos y FR por inmunoturbidimetría y β2m por ELISA. Resultados: 19 pacientes con SSp (Grupo SSp), 28 pacientes con patologías autoinmunes distintas a SSp (Grupo PAD), y 24 controles sanos (Grupo C) fueron incluidos en este estudio. Se evidenció un aumento estadísticamente significativo de β2m en el Grupo SSp respecto al Grupo C (6.19mg/dl vs 2.53mg/dl p<0.001) y respecto al Grupo PAD (6.19 vs 4.38mg/dl p<0.01). En el grupo SSp se observó aumento estadísticamente significativo de IgA (p<0.05) y G (p<0.001) y disminución de C4 (p<0.05) respecto al Grupo C. No se observó correlación entre β2m y el resto de parámetros séricos determinados. Conclusión: β2m permitió discriminar pacientes con SSp de aquellos con otras patologías autoinmunes y sujetos sanos.

    Objetivo: garantizar una buena calidad de vida en la última fase de los pacientes onco-hematológicos debería ser nuestro principal objetivo; a pesar de ello, disponemos de pocos datos a nivel europeo y los estudios publicados son contradictorios. No obstante, la mayoría coinciden en que administrar quimioterapia en la etapa final de la vida impacta de forma negativa en la calidad de vida del paciente. El objetivo principal del estudio es analizar los indicadores de no agresividad del tratamiento en pacientes onco-hematológicos. Como objetivo secundario, realizar un estudio descriptivo de las variables clínicas de los pacientes a los que se les administra quimioterapia en la fase final de la vida y los esquemas más utilizados. Método: se realizó un estudio observacional retrospectivo en un hospital de tercer nivel. Se incluyeron todos los pacientes oncológicos y hematológicos que recibieron quimioterapia (oral o intravenosa) entre enero y diciembre de 2013, a los que se les administró la última quimioterapia en los 90 días previos al fallecimiento. Resultados: se analizaron 823 pacientes que recibieron tratamiento entre enero y diciembre de 2013. De ellos, 106 (13%) cumplían los criterios de inclusión. Un 14,1% (n = 93) de los pacientes oncológicos y un 8,4% (n = 13) de los hematológicos que habían recibido quimioterapia durante el último año de vida lo seguían haciendo en los últimos tres meses. Un 21,7% (n = 23) de los pacientes recibieron quimioterapia en las dos últimas semanas, 41,5% (n = 44) en los últimos 30 días y 78,3% (n = 83) en los últimos dos meses de vida. El 67,9% (n = 72) de los pacientes ingresaron en el hospital durante los últimos tres meses de vida, el 47,2% (n = 50) lo hicieron durante el último mes, el 33% (n = 35) durante las dos últimas semanas y el 10,4% (n = 11) durante los últimos tres días de vida. El 25,5% (n = 27) de los pacientes ingresaron en más de una ocasión durante los 90 días previos al

    levels of fossiliferous marls (bioclasts < 10%), calcareous shales and pyritic black shales (bioclasts < 5%) that contain non-rudist bivalves, algae, echinoids and scarce benthic foraminifers. Microfacies of the prominent black shale bed, which occurs about between 14.5 and 16.3 m within subunit 2b, show a matrix composed essentially of clays (> 50%), framboidal pyrite (1-2.5%), and organic matter (5-7 %). Benthic foraminifers and bioturbation are totally absent within this interval, but there are occasional algal fragments, and very rare ostracods. In contrast to the adjacent levels, the absence of benthic foraminifers lack of bioturbation, and increased OM suggest that the black shale level clearly implies development of anoxic to dysoxic conditions within that interval. Based on the presence of D. desahyesi in subunit 1 its relationship to OAE- 1a remains ambiguous, and its occurrence may be related to a possible regional event due to the complexity of the paleogeography of that region during its tectonic development in the Early Cretaceous.

    The aim of this article is to present part of the results obtained by the intervention made from the author's Master degree project, which consisted in the development of a set of Astronomy classes for first year of High School students from a private school in the "Distrito Federal", Brasilia, Brazil, making use of a didactical material called mini-planetarium (MP) as the main resource. Using Paulo Freire's contextualization and dialogicity ideas as a theoretical framework guided by these lessons, it was proposed to the students the assembly and application of that resource in a planetarium session. During the project, some subjects such as the apparent trajectory of stars through Brasilia's sky, the location of the cardinal points beginning from the Southern Cross constellation, the color of stars and the stars being seen from a particular place were emphasized. It was found that the students showed an improvement of their understanding about these subjects, as well as a significant excitement with the developed methodology.

  10. Physical models for the source of Lascar's harmonic tremor

    2000-08-01

    Over an 18 h interval in April 1994, the tremor at Lascar volcano, Chile, was characterized by a spectrum with narrow peaks at a fundamental freqency of about 0.63 Hz and more than 25 overtones at exact integer multiples. This harmonic tremor was recorded at four three-component, high-dynamic range stations during the deployment of the Proyecto de Investigación Sismológica de la Cordillera Occidental 94 (PISCO'94). Usually this tremor's source is modeled as the resonance of a fluid-filled crack or organ pipe-like structure in the volcano. The resonance of a real, physical structure, however, can produce neither as many overtones nor such exact multiples as those observed in the harmonic tremor at Lascar. Harmonics also occur in a spectrum if the source signal is repetitive but nonsinusoidal. Fluid dynamics offers at least three realistic source models for harmonic tremor which produce repetitive, nonsinusoidal waveforms: the release of gas through a very small outlet (the soda bottle model), slug flow in a narrow conduit, and von Kármán vortices produced at obstacles. These models represent different flow regimes, each with its own characteristic range of Reynolds numbers. For each model the fundamental frequency of the tremor is related to the Reynolds number for the flow. Combining the Reynolds numbers for each model with typical kinematic viscosities for the possible fluids present in a volcano-magma, water, steam, air or some combination, at appropriate temperatures and pressures-provides limits on such physical parameters of the volcano as the dimensions of the flow conduit and the flow velocity of the fluid generating the tremor. If any single one of these three models is actually the process in the volcano which generates harmonic tremor, then the tremor is caused by movements of water or gases in the hydrothermal system near the volcano's surface.

    The causes of childhood blindness depend on factors such as geographic location or the human development index of the populations under study. The main causes in developed countries are genetic and hereditary diseases, while infectious and contagious diseases, together with nutritional and vitamin deficiencies, are the main causes in underdeveloped countries (UDCs). Study of the causes of blindness among children admitted to a regional centre in Nador, Morocco, and among children in Mekele, Ethiopia. The study was carried out in collaboration with two non-governmental organizations based in Madrid, Spain. First, we worked with Fudación Adelias in June 2010, and with Proyecto Visión in October 2012. The study comprised a total of 27 children in Morocco and 85 in Ethiopia. The average age of the children was 10.92 and 6.94 years, respectively. The main causes of blindness in Morocco were hereditary pathologies (25.92%) and refractive errors (14.82%), although trauma (7.40%) and corneal disease (7.40%) are relevant. Among the children from Ethiopia, corneal disease (27.05%) and trauma (20%) were the main causes of blindness, while congenital and hereditary diseases had a lower prevalence (4.70%). The causes of blindness depend on the human development index of the populations under study. While corneal disease and trauma are the main causes observed in UDCs like Ethiopia, hereditary pathologies and refractive errors are the main causes within the Moroccan population studied. A mixed form can be observed in this country, as the cause of blindness found in developed countries, such as congenital and hereditary pathologies which are present alongside the causes normally found in LDCs.

    Background/objective Children of Mexican descent frequently experience household food insecurity both in the United States (US) and Mexico, however, little is known about the associations of food insecurity with dietary intake. This study aimed to understand the level of perceived food insecurity and its association with dietary intake among children of Mexican descent residing in the US and Mexico. Design This cross-sectional study utilized data from a 2006 binational study of five-year-old children of Mexican descent living in migrant communities in California (CA) and Mexico (MX). Methods In CA, children were 301 participants from the CHAMACOS study, a longitudinal birth cohort in a Mexican immigrant community. MX children (n=301) were participants in the Proyecto Mariposa study, which was designed to capture a sample of women and their children living in Mexico who closely resembled the CA sample, yet who never migrated to the US. Household food insecurity was measured using the US Department of Agriculture Food Security Scale and dietary intake was assessed with food frequency questionnaires. Analysis of variance was used to examine unadjusted and adjusted differences in total energy, nutrient intake, and consumption of food groups by household food security status. Results Approximately 39% of the CA mothers and 75% of the MX mothers reported low or very low food security in the last 12 months (p<0.01). Children in the US, experiencing food insecurity consumed more fat, saturated fat, sweets and fried snacks than children not experiencing food insecurity. In contrast, in Mexico food insecurity was associated with lower intake of total carbohydrates, dairy and vitamin B6. Conclusions Programs and policies addressing food insecurity in the US and Mexico may need to take steps to address dietary intake among children in households experiencing food insecurity, possibly through education and programs to increase resources to obtain healthy foods.

    Networks of community health experiences promote interaction and knowledge management in health promotion among their participants. These networks integrate both professionals and social agents who work directly on the ground in small environments, with defined objectives and inclusion criteria and voluntary participation. In this article, networks in Aragon (Spain) are reviewed in order to analyse their role as an information system. The Health Promotion Projects Network of Aragon (Red Aragonesa de Proyectos de Promoción de la Salud, RAPPS) was launched in 1996 and currently includes 73 projects. The average duration of projects is 12.7 years. RAPPS interdisciplinary teams involve 701 people, of which 89.6% are professionals and 10.6% are social agents. The Aragon Health Promoting Schools Network (Red Aragonesa de Escuelas Promotoras de Salud, RAEPS) integrates 134 schools (24.9% of Aragon). The schools teams involve 829 teachers and members of the school community, students (35.2%), families (26.2%) and primary care health professionals (9.8%). Experiences Networks boost citizen participation, have an influence in changing social determinants and contribute to the formulation of plans and regional strategies. Networks can provide indicators for a health promotion information and monitoring system on: capacity building services in the territory, identifying assets and models of good practice, cross-sectoral and equity initiatives. Experiences Networks represent an opportunity to create a health promotion information system, systematising available information and establishing quality criteria for initiatives.

    Galaxy clusters are gravitationally bounded structures in the Universe, which are inhabited by several thousands of galaxies in a very small region in the sky. The central megaparsec of clusters is dominated by early type galaxies, which are observed to obey tight empirical scaling relations as the fundamental plane and the red-sequence. In this work, we present deep Js and Ks-band imaging of 15 galaxy clusters at z≈1, which were discovered in the Red-Sequence Cluster Survey (RCS-1) and followed up using the VLT/ISAAC instrument. We built the Ks-band luminosity function for the composite cluster down to M*+2.5 through the application of a background subtraction method, and we found that it can be described by a Schechter function with Ks*=18.82 and α=-0.42. Furthermore, we built the background subtracted color-magnitude diagram for the composite cluster and measured for the first time the ratio of luminous-to-faint red-sequence galaxies at z=1 from a large ensemble of clusters. We found an increase of 100% in this ratio from z=0.45 to 1.0, that can be explained by a simple evolutionary model developed in this work consisting in an early truncation of the star formation for bright cluster galaxies and a delayed truncation for faint cluster galaxies. Our results suggest that bright cluster galaxies formed most of their stellar content at z=3, that faint cluster galaxies are still forming stars at z=1, and that the red-sequence is not yet fully in place at z=1.

    Living donation is increasingly necessary to address the shortage of organs for transplantation. Analyzing attitudes and influences toward living donation is essential. This study sought to analyze the attitude toward living donation in the population of Bolivians residing in Spain, and the variables that influence their attitude. We selected a sample of Bolivians living in Spain. Respondents were selected using a stratified sampling by age and sex. We used a validated questionnaire of psychosocial aspects (the questionnaire of Proyecto Colaborativo Internacional Donante about Living Kidney Donation [Donación de Vivo Renal in Spanish]), which is self-administered and anonymous. The Student t test, χ(2), and Fisher tests, as well as logistic regression analysis, were used to analyze the gathered data. Of all respondents (n = 206), 83% (n = 170) were in favor of living-related donation, and 32% (n = 66) were in favor of living-unrelated donation. The rest, 8.5% (n = 18) were not in favor of living donation and 8.5% (n = 18) were undecided. Acceptance of the living donation was associated with the religious beliefs of the respondent (P = .014), with no worry about the scars that may remain after the donation (P = .016), and with the risk evaluation of living donation (P = .029). On multivariate analysis, the most important variable was the risk associated with living donation (odds ratio, 6.329; 95% CI, 30.303-1.328; P = .021). Attitudes toward living donation among the Bolivian population residing in Spain is favorable, and represents a group that may be encouraged to become donors. Copyright © 2015 Elsevier Inc.

    Although most people who inject drugs (PWID) report receiving assistance during injection initiation events, little research has focused on risk factors among PWID for providing injection initiation assistance. We therefore sought to determine the influence of non-injection drug use among PWID on their risk to initiate others. We used generalized estimating equation (GEE) models on longitudinal data among a prospective cohort of PWID in Tijuana, Mexico (Proyecto El Cuete IV), while controlling for potential confounders. At baseline, 534 participants provided data on injection initiation assistance. Overall, 14% reported ever initiating others, with 4% reporting this behavior recently (i.e., in the past 6 months). In a multivariable GEE model, recent non-injection drug use was independently associated with providing injection initiation assistance (adjusted odds ratio [AOR] = 2.42, 95% confidence interval [CI] = 1.39-4.20). Further, in subanalyses examining specific drug types, recent non-injection use of cocaine (AOR = 9.31, 95% CI = 3.98-21.78), heroin (AOR = 4.00, 95% CI = 1.88-8.54), and methamphetamine (AOR = 2.03, 95% CI = 1.16-3.55) were all significantly associated with reporting providing injection initiation assistance. Our findings may have important implications for the development of interventional approaches to reduce injection initiation and related harms. Further research is needed to validate findings and inform future approaches to preventing entry into drug injecting.

    Introduction Latinas in the United States on average have poorer birth outcomes than Whites, yet considerable heterogeneity exists within Latinas. Puerto Ricans have some of the highest rates of adverse outcomes and are understudied. The goal of this study was to determine if acculturation was associated with adverse birth outcomes in a predominantly Puerto Rican population. Methods We conducted a secondary analysis of Proyecto Buena Salud, a prospective cohort study conducted from 2006 to 2011. A convenience sample of pregnant Latina women were recruited from a tertiary care hospital in Massachusetts. Acculturation was measured in early pregnancy; directly via the Psychological Acculturation Scale, and via proxies of language preference and generation in the United States. Birth outcomes (gestational age and birthweight) were abstracted from medical records (n = 1362). Results After adjustment, psychological acculturation, language preference, and generation was not associated with odds of preterm birth. However, every unit increase in psychological acculturation score was associated with an increase in gestational age of 0.22 weeks (SE = 0.1, p = 0.04) among all births. Women who preferred to speak Spanish (β = −0.39, SE = 0.2, p = 0.02) and who were first generation in the US (β = −0.33, SE = 0.1, p = 0.02) had significantly lower gestational ages than women who preferred English or who were later generation, respectively. Similarly, women who were first generation had babies who weighed 76.11 g less (SE = 35.2, p = 0.03) than women who were later generation. Discussion We observed a small, but statistically significant adverse impact of low acculturation on gestational age and birthweight in this predominantly Puerto Rican population. PMID:26694041

    Numerous animals have declining populations due to habitat loss, illegal wildlife trade, and climate change. The cotton-top tamarin (Saguinus oedipus) is a Critically Endangered primate species, endemic to northwest Colombia, threatened by deforestation and illegal trade. In order to assess the current state of this species, we analyzed changes in the population of cotton-top tamarins and its habitat from 2005 to 2012. We used a tailor-made "lure strip transect" method to survey 43 accessible forest parcels that represent 30% of the species' range. Estimated population size in the surveyed region was approximately 2,050 in 2005 and 1,900 in 2012, with a coefficient of variation of approximately 10%. The estimated population change between surveys was -7% (a decline of approximately 1.3% per year) suggesting a relatively stable population. If densities of inaccessible forest parcels are similar to those of surveyed samples, the estimated population of cotton-top tamarins in the wild in 2012 was 6,946 individuals. We also recorded little change in the amount of suitable habitat for cotton-top tamarins between sample periods: in 2005, 18% of surveyed forest was preferred habitat for cotton-top tamarins, while in 2012, 17% percent was preferred. We attribute the relatively stable population of this Critically Endangered species to increased conservation efforts of Proyecto Tití, conservation NGOs, and the Colombian government. Due to continued threats to cotton-top tamarins and their habitat such as agriculture and urban expansion, ongoing conservation efforts are needed to ensure the long-term survival of cotton-top tamarins in Colombia.

    Objectives To prospectively evaluate the association between gestational weight gain (GWG), prepregnancy body mass index (BMI), and hypertensive disorders of pregnancy using the revised Institute of Medicine (IOM) Guidelines. Methods We examined these associations among 1359 participants in Proyecto Buena Salud, a prospective cohort study conducted from 2006 to 2011 among women from the Caribbean Islands. Information on prepregnancy BMI, GWG, and incident diagnoses of hypertension in pregnancy were based on medical record abstraction. Results Four percent (n = 54) of women were diagnosed with hypertension in pregnancy, including 2.6 % (n = 36) with preeclampsia. As compared to women who gained within IOM GWG guidelines (22.8 %), those who gained above guidelines (52.5 %) had an odds ratio of 3.82 for hypertensive disorders (95 % CI 1.46-10.00; ptrend = 0.003) and an odds ratio of 2.94 for preeclampsia (95 % CI 1.00-8.71, ptrend = 0.03) after adjusting for important risk factors. Each one standard deviation (0.45 lbs/week) increase in rate of GWG was associated with a 1.74 odds of total hypertensive disorders (95 % CI 1.34-2.27) and 1.86 odds of preeclampsia (95 % CI 1.37-2.52). Conclusions for Practice Findings from this prospective study suggest that excessive GWG is associated with hypertension in pregnancy and could be a potentially modifiable risk factor in this high-risk ethnic group.

    Policing practices are key drivers of HIV among people who inject drugs (PWID). This paper describes the protocol for the first study to prospectively examine the impact of a police education programme (PEP) to align law enforcement and HIV prevention. PEPs incorporating HIV prevention (including harm reduction programmes like syringe exchange) have been successfully piloted in several countries but were limited to brief pre-post assessments; the impact of PEPs on policing behaviours and occupational safety is unknown. Proyecto ESCUDO (SHIELD) aims to evaluate the efficacy of the PEP on uptake of occupational safety procedures, as assessed through the incidence of needle stick injuries (NSIs) (primary outcome) and changes in knowledge of transmission, prevention and treatment of HIV and viral hepatitis; attitudes towards PWID, adverse behaviours that interfere with HIV prevention and protective behaviours (secondary outcomes). ESCUDO is a hybrid type I design that simultaneously tests an intervention and an implementation strategy. Using a modified stepped-wedge design involving all active duty street-level police officers in Tijuana (N = ∼ 1200), we will administer one 3 h PEP course to groups of 20-50 officers until the entire force is trained. NSI incidence and geocoded arrest data will be assessed from department-wide de-identified data. Of the consenting police officers, a subcohort (N=500) will be randomly sampled from each class to undergo pre-PEP and post-PEP surveys with a semiannual follow-up for 2 years to assess self-reported NSIs, attitudes and behaviour changes. The impact on PWIDs will be externally validated through a parallel cohort of Tijuana PWIDs. Research ethics approval was obtained from the USA and Mexico. Findings will be disseminated through open access to protocol materials through the Law Enforcement and HIV Network. NCT02444403. Published by the BMJ Publishing Group Limited.

    Research indicates social integration and social isolation are related to health, and Latino day laborers (LDLs) tend to be socially isolated and, thus, at high risk for adverse health consequences. relationships among social isolation, social integration, self-rated health (SRH), and demographics were examined in a sample of LDLs to contribute to the literature on social networks and health in this and other migrant populations. We analyzed data from 324 LDLs who participated in Proyecto SHILOS (Salud del Hombre Inmigrante Latino), a Houston-based survey of Latino immigrant men's health. Based on the literature, we hypothesized SRH would be (1) positively associated with social integration and (2) negatively associated with social isolation. All proposed measures were first entered into a correlation matrix to identify significant bivariate relationships (p ≤ .05, two-tailed). Associations between variables that were directly correlated with SRH and variables that were, in turn, proximally associated with these variables were then used to develop a structural equation path model of SRH. Individual paths in the model were measured for significance, and goodness of fit was assessed by the model chi-square, the Comparative Fit Index, and the Root Mean Square Error of Approximation. Inconsistent with the first hypothesis, SRH was negatively associated with social integration, as measured by the number of trusted friends. Consistent with the second hypothesis, SRH was negatively associated with social isolation, as measured by needing someone to talk to. More frequent contact with family was also negatively associated with social isolation. Our findings suggest social integration may not always protect and promote health. Therefore, assessing the quality of LDLs' different relationships, not just the quantity, is vital. Future studies should further analyze the effects that social resources have on perceptions of social isolation and health in LDLs and other

    Objectives To examine associations between depression and preterm birth and small-for gestational age (SGA) among women of predominantly Puerto Rican descent, a population who experiences disparities in adverse birth outcomes and one of the highest infant mortality rates in the United States. Methods Proyecto Buena Salud (PBS) was a prospective cohort study conducted from 2006 to 2011 at a large tertiary care center in Western Massachusetts. Caribbean Islander (i.e., Puerto Rican and Dominican Republic) women were interviewed in early, mid and late pregnancy. Among 1262 participants, associations between depression, assessed using the Edinburgh Postnatal Depression Scale, and risk of preterm birth and small-for-gestational age (SGA) were evaluated. Results Women with at least probable minor depression [odds ratio (OR) = 1.77 (95% confidence interval (CI) = 1.02, 3.07)] or probable major depression [OR = 1.82 (95% CI = 1.01, 3.25)] in mid-pregnancy had an increased risk of SGA compared to non-depressed women in adjusted analyses. Borderline significant associations were observed between increasing levels of depressive symptom scores in early and mid-pregnancy [OR = 1.05 (95% CI = 1.00, 1.11) and OR = 1.04 (95% CI = 1.00, 1.09), respectively] and each additional trimester of exposure to probable major depression across mid- to late pregnancy [OR = 1.66 (95% CI = 1.00, 2.74)] and SGA. Late pregnancy depression was not associated with SGA; depression during pregnancy was not associated with preterm birth. Conclusions for Practice In this population of predominantly Puerto Rican women, mid-pregnancy depression increased risk for SGA. Findings can inform culturally appropriate, targeted interventions to identify and treat pregnant women with depression.

    Hispanic preschoolers have higher rates of BMI ≥85th percentile than any other racial/ethnic group. To identify underpinnings of this disparity, we compared early feeding practices and subsequent weight status for a sample of infants of low-income, Hispanic immigrant mothers with participants from the Infant Feeding Practices Study II (IFPS II). Proyecto de Bebés Hispanos Saludables (PBHS) collected medical record data for mother-infant dyads (n = 550) from a large pediatric clinic for low-income families and merged it with IFPS II data (n = 1502) to compare early feeding practices and late infancy weight status. Mode of milk delivery for PBHS mothers was less likely to be exclusive breastfeeding at 6 months (9.0% vs. 27.5%), but more likely to be both breast and bottle feeding (43.5% vs. 26.3%) compared to IFPS II mothers. No difference was found in age for solid food introduction. Weight for age of PBHS infants was more likely to be ≥85th percentile at 12 months than IFPS II infants (39.1% vs. 25.4%). Both PBHS and IFPS II infants were more likely to be ≥85th percentile at 1 year if mode of milk delivery was bottle only at 6 months compared to those who were breastfed only, even after adjusting for potential confounders. Differences in PBHS and IFPS II feeding practices and weight status suggest additional studies of modifiable, early life risk factors are needed to inform clinical and public health interventions that reduce childhood obesity for this growing sector of the US population.

    The Latin American (LA) population in Spain is ever increasing in size and is perfectly integrated into the social structure. The objectives were to analyze the attitude of citizens, born in Latin America and living in Spain, toward living kidney donation (LKD) and to determine the psychosocial variables affecting this attitude. A sample of LA residents living in Spain was obtained randomly in 2010 and stratified according to the respondent's nationality (n = 1314). Attitude was evaluated using a validated questionnaire ("Proyecto Colaborativo Internacional Donante sobre Donación de Vivo Renal" Ríos). The survey was self-administered and completed anonymously. The questionnaire completion rate was 86% (n = 1.132). A total of 89% (n = 1003) were in favor of related living donation, and 30% if the donation were unrelated. The variables associated with attitude toward LKD were as follows: sex (p = 0.043); marital status (p = 0.013); previous experience of organ donation (p = 0.009); attitude toward deceased organ donation (p < 0.001); a respondent's belief that he or she could be a possible recipient of a future transplant (p < 0.001); knowledge of a partner's opinion (p = 0.021); family discussion about organ donation (p = 0.001); knowledge of the view of one's religion toward donation (p < 0.001); concern about "mutilation" after donation (p = 0.004); and evaluation of the risk from living donation (p = 0.036). The attitude of LA citizens residing in Spain was favorable both toward related LKD and unrelated living donation. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Numerous animals have declining populations due to habitat loss, illegal wildlife trade, and climate change. The cotton-top tamarin (Saguinus oedipus) is a Critically Endangered primate species, endemic to northwest Colombia, threatened by deforestation and illegal trade. In order to assess the current state of this species, we analyzed changes in the population of cotton-top tamarins and its habitat from 2005 to 2012. We used a tailor-made “lure strip transect” method to survey 43 accessible forest parcels that represent 30% of the species’ range. Estimated population size in the surveyed region was approximately 2,050 in 2005 and 1,900 in 2012, with a coefficient of variation of approximately 10%. The estimated population change between surveys was -7% (a decline of approximately 1.3% per year) suggesting a relatively stable population. If densities of inaccessible forest parcels are similar to those of surveyed samples, the estimated population of cotton-top tamarins in the wild in 2012 was 6,946 individuals. We also recorded little change in the amount of suitable habitat for cotton-top tamarins between sample periods: in 2005, 18% of surveyed forest was preferred habitat for cotton-top tamarins, while in 2012, 17% percent was preferred. We attribute the relatively stable population of this Critically Endangered species to increased conservation efforts of Proyecto Tití, conservation NGOs, and the Colombian government. Due to continued threats to cotton-top tamarins and their habitat such as agriculture and urban expansion, ongoing conservation efforts are needed to ensure the long-term survival of cotton-top tamarins in Colombia.

    Marine hydrokinetic power projects will operate as marine environments change in response to increased atmospheric carbon dioxide concentrations. We considered how tidal power development and stressors resulting from climate change may affect Puget Sound species listed under the U.S. Endangered Species Act (ESA) and their food web. We used risk tables to assess the singular and combined effects of tidal power development and climate change. Tidal power development and climate change posed risks to ESA-listed species, and risk increased with incorporation of the effects of these stressors on predators and prey of ESA-listed species. In contrast, results of a model of strikes on ESA-listed species from turbine blades suggested that few ESA-listed species are likely to be killed by a commercial-scale tidal turbine array. We applied scenarios to a food web model of Puget Sound to explore the effects of tidal power and climate change on ESA-listed species using more quantitative analytical techniques. To simulate development of tidal power, we applied results of the blade strike model. To simulate environmental changes over the next 50 years, we applied scenarios of change in primary production, plankton community structure, dissolved oxygen, ocean acidification, and freshwater flooding events. No effects of tidal power development on ESA-listed species were detected from the food web model output, but the effects of climate change on them and other members of the food web were large. Our analyses exemplify how natural resource managers might assess environmental effects of marine technologies in ways that explicitly incorporate climate change and consider multiple ESA-listed species in the context of their ecological community.

  9. Attenuation tomography in the western central Andes: A detailed insight into the structure of a magmatic arc

    High-quality data from 1498 local earthquakes recorded by the PISCO '94 (Proyecto de Investigatión Sismológica de la Cordillera Occidental, 1994) and ANCORP '96 (Andean Continental Research Project, 1996) temporary seismological networks allowed the detailed determination of the three-dimensional (3-D) attenuation structure (Qp-1) beneath the recent magmatic arc in the western central Andes (20° to 24°S). Assuming a frequency-independent Qp-1 in a frequency band between 1 and 30 Hz, whole path attenuation (t*) was estimated from the amplitude spectra of the P waves using spectral ratios and a spectral inversion technique. The damped least squares inversion (tomography) of the data reveals a complex attenuation structure. Crust and mantle of the forearc and subducting slab are generally characterized by low attenuation (Qp > 1000). Crust and mantle beneath the magmatic arc show elevated attenuation. The strongest anomaly of extremely low Qp is found in the crust between 22° and 23°S beneath the recent volcanic arc (Qp < 100). N-S variations can be observed: The western flank of the crustal attenuation anomaly follows the curved course of the volcanic front. North of 21°S the attenuation is less developed. In the northern part of the study area the low-Qp zone penetrates in the forearc mantle down to the subducting slab. In the south a deeper zone of high attenuation is resolved between 23° and 24°S directly above the subducting slab. Low Qp in the mantle correlates with earthquake clusters. The strong crustal attenuation is confined to the distribution of young ignimbrites and silicic volcanism and is interpreted as a thermally weakened zone with partial melts. The attenuation pattern in the upper mantle might reflect the variable extent of the asthenosphere and maps variations of subduction-related hydration processes in the mantle wedge from slab-derived fluids.

    Patients with chronic obstructive pulmonary disease (COPD) usually complain of symptoms such as cough, sputum, wheezing, and dyspnea. Little is known about clinical symptoms in individuals with restrictive ventilatory impairment. The aim of this study was to compare the prevalence and type of respiratory symptoms in patients with COPD to those reported by individuals with restrictive ventilatory impairment in the Proyecto Latinoamericano de Investigacion en Obstruccion Pulmonar study. Between 2002 and 2004, individuals ≥40 years of age from five cities in Latin America performed pre and post-bronchodilator spirometry and had their respiratory symptoms recorded in a standardized questionnaire. Among the 5315 individuals evaluated, 260 (5.1%) had a restrictive spirometric diagnosis (forced vital capacity (FVC) < lower limit of normal (LLN) with forced expiratory volume in the first second to forced vital capacity ratio (FEV1/FVC) ≥ LLN; American Thoracic Society (ATS)/European Respiratory Society (ERS) 2005) and 610 (11.9%) were diagnosed with an obstructive pattern (FEV1/FVC < LLN; ATS/ERS 2005). Patients with mild restriction wheezed more ((30.8%) vs. (17.8%); p < 0.028). No difference was seen in dyspnea, cough, and sputum between the two groups after adjusting for severity stage. The health status scores for the short form 12 questionnaire were similar in restricted and obstructed patients for both physical (48.4 ± 9.4 vs. 48.3 ± 9.8) and mental (50.8 ± 10.6 vs. 50.0 ± 11.5) domains. Overall, respiratory symptoms are not frequently reported by patients with restricted and obstructed patterns as defined by spirometry. Wheezing was more frequent in patients with restricted pattern compared with those with obstructive ventilatory defect. However, the prevalence of cough, sputum production, and dyspnea are not different between the two groups when adjusted by the same severity stage.

    Objective Investments have been made to alter the food environment of neighbourhoods that have a disproportionate number of unhealthy food venues. Corner store conversions are one strategy to increase access to fruits and vegetables (F&V). Although the literature shows modest success, the effectiveness of these interventions remains equivocal. The present paper reports on the evaluation of Proyecto MercadoFRESCO, a corner store conversion intervention in two Latino communities. Design A repeated cross-sectional design was employed. Data were stratified by intervention arm and bivariate tests assessed changes over time. Logistic and multiple regression models with intervention arm, time and the interaction of intervention and time were conducted. Supplementary analyses account for clustering of patrons within stores and staggering of store conversions. Setting Three stores were converted and five stores served as comparisons in East Los Angeles and Boyle Heights, California, USA. Subjects Store patrons were interviewed before (n 550) and after (n 407) the intervention. Results Relative to patrons of comparison stores, patrons of intervention stores demonstrated more favourable perceptions of corner stores and increased purchasing of F&V during that store visit. Changes were not detected in store patronage, percentage of weekly dollars spent on food for F&V or daily consumption of F&V. Conclusions Consistent with some extant food environment literature, findings demonstrate limited effects. Investments should be made in multilevel, comprehensive interventions that target a variety retail food outlets rather than focusing on corner stores exclusively. Complementary policies limiting the availability, affordability and marketing of energy-dense, nutrient-poor foods should also be pursued. PMID:28578744

    Objetivo: El objetivo de este estudio fue analizar la utilidad de diferentes test de condición física para detectar el riesgo de sufrir obesidad sarcopénica (OS) en octogenarios. Métodos: 306 sujetos (76 hombres, 230 mujeres) con una media de edad de 82,5±2,3 años, del total de la muestra del Proyecto Multi-céntrico EXERNET cumplieron con los criterios de inclusión. La composición corporal se evaluó en todos los sujetos mediante impedancia bioeléctrica. Se crearon 4 grupos basados en el porcentaje de masa grasa y masa muscular: 1) normal, 2) elevada masa grasa, 3) baja masa muscular y 4) OS. La condición física fue evaluada utilizando 8 test diferentes adaptados de las baterías “Senior Fitness Test” y “Eurofit” (batería EXERNET). La probabilidad de padecer OS en función del nivel de condición física se estudió mediante regresión logística. Resultados: Entre las pruebas de condición física estudiadas, los test que mejor predecían el riesgo de sufrir OS fueron la falta de fuerza de piernas, fuerza de brazos, agilidad, velocidad y equilibrio en hombres; 95% CI [(0,606-0,957); (0,496-0,882); (1,116-3,636); (1,060-1,825); (0,913-1,002); todos p.

    Introducción: en los últimos tiempos se ha observado un aumento exponencial de las tasas de sobrepeso y obesidad en la población infanto-juvenil, a la vez que un abandono del patrón alimentario mediterráneo. Además, gran parte de la población adolescente autopercibe erróneamente su peso. Objetivos: analizar la prevalencia de exceso de peso, la autopercepción del peso y los hábitos alimentarios en una muestra infanto-juvenil. Buscar relaciones entre dichas variables y el bienestar psicosocial. Método: 87 alumnos de la ESO participaron voluntariamente en el proyecto mediante la cumplimentación de cuestionarios y la recogida de peso y talla tanto reales como autopercibidos. Resultados: un 28,73% de la muestra presentaba sobrepeso y un 9,19% obesidad. El 27,48 % del total de los encuestados autopercibía erróneamente su peso y únicamente la cuarta parte de la muestra presentó un patrón alimentario mediterráneo correcto. Se obtiene una mayor frecuencia de control del peso a medida que la autopercepción de este aumenta. Discusión y conclusiones: gran parte de la muestra subestima su peso y existe una posible asociación entre la ausencia de desayuno y mayores tasas de exceso de peso infanto-juvenil. Se observa un aumento progresivo de la prevalencia de sobrepeso y obesidad en adolescentes, así como la necesidad de implementar labores de educación nutricional tras analizar sus hábitos alimentarios.

    Introducción: El envejecimiento es un proceso fisiológico natural asociado a diferentes cambios, entre los que se encuentra un descenso de la condición física. Objetivos: Establecer la relación entre un comportamiento sedentario (permanecer sentada =?4 horas/día) y la condición física en 457 mujeres mayores de 65 años. Metodología: La condición física se evaluó mediante 8 test (adaptados de las baterías “Senior Fitness Test” y “Eurofit Testing Battery”). Se utilizó ANOVA para analizar las diferencias entre grupos en función de las horas de sedestación y regresión logística para estudiar la asociación del comportamiento sedentario con una baja condición física, utilizando como referencia el percentil 20 de los valores normativos en España (Proyecto EXERNET). Resultados: Las mujeres sedentarias obtuvieron valores más bajos en las pruebas de equilibrio, fuerza de piernas y brazos, flexibilidad de brazos, velocidad y resistencia (p < 0,05). Además, aquellas mujeres que permanecían sentadas =?4 horas/día tenían mayor probabilidad de tener baja condición física en la mayoría de las pruebas citadas anteriormente, independientemente de las horas dedicadas a caminar (p < 0,05). Conclusión: Permanecer mucho tiempo sentada influye negativamente sobre la condición física de las mujeres postmenopáusicas independientemente del tiempo que caminen.

    COPD is a major worldwide problem with a rising prevalence. Despite its importance, there is a lack of information regarding underdiagnosis and misdiagnosis of COPD in different countries. As part of the Proyecto Latinoamericano de Investigación en Obstrucción Pulmonar study, we examined the relationship between prior diagnostic label and airway obstruction in the metropolitan areas of five Latin American cities (São Paulo, Santiago, Mexico City, Montevideo, and Caracas). A two-stage sampling strategy was used in each of the five areas to obtain probability samples of adults aged >or= 40 years. Participants completed a questionnaire that included questions on prior diagnoses, and prebronchodilator and postbronchodilator spirometry. A study diagnosis of COPD was based on airway obstruction, defined as a postbronchodilator FEV(1)/FVC < 0.70. Valid spirometry and prior diagnosis information was obtained for 5,303 participants; 758 subjects had a study diagnosis of COPD, of which 672 cases (88.7%) had not been previously diagnosed. The prevalence of undiagnosed COPD was 12.7%, ranging from 6.9% in Mexico City to 18.2% in Montevideo. Among 237 subjects with a prior COPD diagnosis, only 86 subjects (36.3%) had postbronchodilator FEV(1)/FVC < 0.7, while 151 subjects (63.7%) had normal spirometric values. In the same group of 237 subjects, only 34% reported ever undergoing spirometry prior to our study. Inaccurate diagnostic labeling of COPD represents an important health problem in Latin America. One possible explanation is the low rate of spirometry for COPD diagnosis.

    Burden of Obstructive Lung Disease (BOLD) Initiative sites worldwide. To measure the prevalence of chronic obstructive pulmonary disease (COPD) and its risk factors, investigate variation in prevalence across countries and develop standardized methods that can be used in industrialized and developing countries. Non-institutionalized adults aged > or =40 years were recruited using population-based sampling plans. Each site targeted a minimum of 600 participants (300 women, 300 men), who filled out questionnaires and performed spirometry before and after administration of 200 mug salbutamol using standardized methods. Random effects meta-analysis models were used to estimate pooled prevalence estimates and risk factor effects and to test for heterogeneity across sites and sex. Data published from 12 sites (n = 8775) showed that the estimated population prevalence of COPD (Global Initiative for Chronic Obstructive Lung Disease [GOLD] Stage II and higher) was 10.1 +/- SE = 4.8% overall (11.8 +/- 7.9% for men and 8.5 +/- 5.8% for women). Prevalence increased with age and pack-years of smoking, but other less understood risk factors, such as biomass heating and cooking exposures, occupational exposures and tuberculosis, also contribute to the location-specific variations in disease prevalence that BOLD is finding. BOLD has estimated the social and economic burden of COPD in 12 countries to date. BOLD and the Proyecto Latinoamericano de Investigación en Obstrucción Pulmonar (the PLATINO study) are developing a growing database of COPD prevalence. Cigarette smoking and age are the most important COPD risk factors, but other risk factors should also be explored.

  17. Horizonal and Vertical Spatial Patterns of Radon and Other Soil-gases Across the El Pilar Fault Trace at Guaraphiche, Edo. Surce (Venezuela)

    Soil-gases (radon, thoron, carbon dioxide and hydrogen) were measured at 63-cm depths along a transect perpendicular to the rupture (fault trace) from the 1997 Caricao earthquake (Mw=6.9) at Guarapiche, state of Sucre (Venezuela). The transect was about 40 meters long with ten sampling points with the spacings was smaller near the rupture. The shapes of the horizontal spatial patterns for radon (Rn-222), thoron (Rn-220) and total radon (Rn-222+Rn-220) were similar; the gas concentrations increased from both ends of the transect toward the rupture where a dip (valley) occurred. Both carbon dioxide and hydrogen gases showed anomalous values at the same sampling points. Twin peaks (anomalies) had been previously reported and suggested that they were due to blockage in the rupture. We have also determined soil-gases from 25-cm to 155-cm depths near the rupture and at the ends of the transect. The results showed that the soil-gas concentrations were not only higher in the upper levels (less than 65-cm) near the fault trace but were similar or greater than the lower levels. Thus, producing the twin peaks when soil-gas sampling was performed at the 65-cm depth. When the sampling was performed at only 45-cm depth the dip over the rupture was much less and the patterns looked more like a broad doublet peak. In conclusion, one can clearly see that not only positive soil-gas anomalies can occur over a fault trace but also negative ones too. 1) This work was partially funded by a research contract from the Venezuelan National Science Foundation (CONICIT Proyecto S1-95000448). 2) Mailing Address: Centro de Quimica, 8424 NW 56th Street, Suite 00204,Miami, Fl 33166 (USA).

    Agricultural activities associated mainly with soybean crops affect the natural environment and wildlife by habitat destruction and the extensive use of agrochemicals. The aim of this study was to evaluate immunotoxic effects of the insecticides cypermethrin (CYP) and endosulfan (END) in Caiman latirostris analyzing total blood cell count (TWBC) and differential white blood cell count (DWBC) after in ovo and in vivo exposure. Eggs (in ovo) and hatchlings (in vivo) from nests harvested in natural habitats were artificially incubated and reared under controlled conditions in the Proyecto Yacaré (Gob.Santa Fe/MUPCN) facilities. Exposure of embryos was performed by topication on the eggshell during the first stage of development. The treatments were distilled water (negative control; NC), ethanol (vehicle control; VC), four groups treated with different concentrations of CYP and four groups with END. In vivo exposure was performed by immersion; treatments were NC, VC, two groups exposed to CYP and two to END. After embryonic exposure to the insecticides, no differences were found in TWBC or DWBC among the neonates exposed to pesticides versus controls. In the in vivo scenario, similar results were obtained for TWBC, but DWBC data showed differences between NC hatchlings and CYP-1 hosts for heterophil, lymphocyte and monocyte levels, and between NC and END-1 hosts for lymphocyte and monocyte levels. Research on the effects of pesticide exposure on this species is of special interest not only to assess the impact on caiman populations, but also to further characterize the species as a potential sentinel of ecosystem health.

El CH es una molécula de amplia distribución en el espacio interestelar y una de las pocas especies que han sido observadas tanto con técnicas de radio como ópticas. Desde el punto de vista tecnológico se ha desarrollado un cabezal de receptor que permitirá la realización de observaciones polarimétricas en la frecuencia de 3,3 GHz, con una temperatura del sistema de 60 K y un ancho de banda de 140 MHz, y que será instalado en el foco primario de la antena parabólica del IAR. El cabezal del receptor es capaz de detectar señales polarizadas, separando las componentes de polarización circular derecha e izquierda. Para tal fin el cabezal consta de dos ramas receptoras que amplificarán la señal y la trasladarán a una frecuencia más baja (frecuencia intermedia), permitiendo de esa forma un mejor transporte de la señal a la sala de control para su posterior procesamiento. El receptor además de tener características polarimétricas, podrá ser usado en el continuo y en la línea, utilizando las ventajas observacionales y de procesamiento de señal que actualmente posee el IAR.

    Introducción: Los trastornos de la conducta alimentaria (TCA) son especialmente frecuentes en los jóvenes. Objetivo: Determinar la prevalencia de TCA en jóvenes universitarios y sus factores asociados. Metodología: Estudio de prevalencia en jóvenes universitarios españoles del proyecto uniHcos. Mediante regresión logística no condicional se determinó la magnitud de la asociación entre los factores de riesgo asociados al estilo de vida y padecer un TCA medido mediante el cuestionario Sick, Control, One, Fat, Food (SCOFF). Resultados: La prevalencia de TCA fue del 19,5%, siendo mayor en mujeres (ORa=1,59; p=0,006). En los chicos, tener criterios de padecer TCA se asoció con vivir en colegios mayores, con realizar “binge drinking”, y uso problemático de internet. En las mujeres el estudiar titulaciones diferentes a las ciencias de la salud (ORa=1,50) y el uso problemático de internet (ORa=2,33). Aquellas mujeres con riesgo de TCA presentaban con mayor frecuencia depresión (ORa=2,02), dolores menstruales (ORa=1,81) y mala salud percibida (ORa=1,70). En los hombres, aquellos con riesgo de TCA presentaban con mayor frecuencia una mala salud percibida (ORa=2,42). Conclusiones: El riesgo de obtener resultados positivos en el SCOFF en nuestro estudio es similar a lo publicado para otras poblaciones de estudiantes, así como su asociación con determinadas adicciones y problemas de salud. Se observaron diferencias en función del sexo que precisan atención en el diseño de estrategias de prevención y control.

    The academic year 2011-12 is the second one implementing Bologna process in ETSI at the subjects of Agricultural Chemistry I and Chemistry II in the new four Degrees: Graduate in Engineering and Agricultural Science, Food Engineering Graduate, Graduate Environmental and engineering Graduate in Biotechnology, for it has been necessary to design and implement new interactive methodologies in the teaching-learning process based on the use of the virtual platform of the UPM, implement new evaluation systems that promote continued participation active student and the development of educational materials to support the subjects of chemistry designed new degrees within the EEES. In addition to the above actions, an assessment test prior chemistry knowledge has been made to all students who enter into Agricultural Grades, improving laboratory practices and the comparative study of academic obtained by the students of the new grades in the subjects of chemistry during the year 2011-12 compared to the 2010-11 academic year. More than 15,000 data have showed a good correlation between the student's prior knowledge, the level test performed, test scores, the overall success rate of the course and the abandonment of the different degrees. Academic results show a higher percentage of students enrolled and presented on a greater number of passes on students enrolled in the 2011-12 academic year for students enrolled in the previous academic year. The improved results have influenced the actions taken and the level of knowledge with students entering. Finally, we propose possible solutions to fix these results in future courses, aiming to improve the degree of efficiency, success and significant absenteeism in the first year as it will condition the dropout rate of these new degrees.

    Introduction Policing practices are key drivers of HIV among people who inject drugs (PWID). This paper describes the protocol for the first study to prospectively examine the impact of a police education programme (PEP) to align law enforcement and HIV prevention. PEPs incorporating HIV prevention (including harm reduction programmes like syringe exchange) have been successfully piloted in several countries but were limited to brief pre–post assessments; the impact of PEPs on policing behaviours and occupational safety is unknown. Objectives Proyecto ESCUDO (SHIELD) aims to evaluate the efficacy of the PEP on uptake of occupational safety procedures, as assessed through the incidence of needle stick injuries (NSIs) (primary outcome) and changes in knowledge of transmission, prevention and treatment of HIV and viral hepatitis; attitudes towards PWID, adverse behaviours that interfere with HIV prevention and protective behaviours (secondary outcomes). Methods/analysis ESCUDO is a hybrid type I design that simultaneously tests an intervention and an implementation strategy. Using a modified stepped-wedge design involving all active duty street-level police officers in Tijuana (N=∼1200), we will administer one 3 h PEP course to groups of 20–50 officers until the entire force is trained. NSI incidence and geocoded arrest data will be assessed from department-wide de-identified data. Of the consenting police officers, a subcohort (N=500) will be randomly sampled from each class to undergo pre-PEP and post-PEP surveys with a semiannual follow-up for 2 years to assess self-reported NSIs, attitudes and behaviour changes. The impact on PWIDs will be externally validated through a parallel cohort of Tijuana PWIDs. Ethics/dissemination Research ethics approval was obtained from the USA and Mexico. Findings will be disseminated through open access to protocol materials through the Law Enforcement and HIV Network. Trial registration number NCT02444403. PMID:26260350

    Background In August 2009, Mexico reformed its drug laws and decriminalized small quantities of drugs for personal use; offenders caught three times will be mandated to enter drug treatment. However, little is known about the quality or effectiveness of drug treatment programs in Mexico. We examined injection drug users’ (IDUs) experiences in drug treatment in Tijuana, Mexico, with the goal of informing program planning and policy. Methods We examined qualitative and quantitative data from Proyecto El Cuete, a multi-phased research study on HIV risk among IDUs in Tijuana. Phase I consisted of 20 in-depth interviews and Phase II employed respondent-driven sampling to recruit 222 IDUs for a quantitative survey. We also reviewed national drug policy documents, surveillance data, and media reports to situate drug users’ experiences within the broader sociopolitical context. Results Participants in the qualitative study were 50% male with a mean age of 32; most injected heroin (85.0%) and methamphetamine (60.0%). The quantitative sample was 91.4% male with a mean age of 35; 98.2% injected heroin and 83.7% injected heroin and methamphetamine together. The majority of participants reported receiving treatment: residential treatment was most common, followed by methadone; other types of services were infrequently reported. Participants’ perceptions of program acceptability and effectiveness were mixed. Mistreatment emerged as a theme in the qualitative interviews and was reported by 21.6% of Phase II participants, primarily physical (72.0%) and verbal (52.0%) abuse. Conclusions Our results point to the need for political, economic, and social investment in the drug treatment system before offenders are sentenced to treatment under the revised national drug law. Resources are needed to strengthen program quality and ensure accountability.

    Prior studies of the association between physical activity and hypertensive disorders of pregnancy have been conflicting; the majority focused on leisure-time activity only, did not use physical activity questionnaires validated for pregnancy, and were conducted in primarily non-Hispanic white populations. We prospectively evaluated this association among 1240 Hispanic women in Proyecto Buena Salud. The Pregnancy Physical Activity Questionnaire, validated for use in pregnancy, was used to assess pre- and early pregnancy sports/exercise, household/caregiving, occupational and transportation activity. Diagnoses of hypertensive disorders of pregnancy were based on medical record abstraction and confirmed by the study obstetrician. A total of 49 women (4.0%) were diagnosed with a hypertensive disorder of pregnancy, including 32 women (2.6%) with pre-eclampsia. In age-adjusted analyses, high levels of early pregnancy household/caregiving activity were associated with reduced risk of total hypertensive disorders (OR = 0.4, 95% CI 0.1-0.9) and pre-eclampsia (OR = 0.3, 95% CI 0.1-0.9) relative to low levels; however, these findings were no longer statistically significant in multivariable models. Pre-pregnancy activity and pattern of activity from pre- to early-pregnancy were not significantly associated with risk. Finally, sedentary behavior was not significantly associated with hypertensive disorders. Findings from this prospective study of Hispanic women were consistent with those of prior prospective cohorts indicating that physical activity prior to and during early pregnancy does not significantly reduce risk of hypertensive disorders of pregnancy.

    Hispanic farm workers and their families in the U.S. face a number of environmental and occupational health risks, yet they are rarely given the opportunity to choose the focus of the research and interventions that take place in their communities. Community-based participatory research (CBPR) can be one effective approach to changing this situation. CBPR is an approach to research that makes community members partners in research rather than subjects of research. This article describes the experience of El Proyecto Bienestar (The Well-Being Project), a CBPR project in the Yakima Valley, Washington, with the aim of facilitating the Hispanic community's involvement in the identification and prioritization of occupational and environmental health issues among farm workers. The project utilized three forms of data collection (key informant interviews, community surveys, and a town hall meeting) to create a list of environmental and occupational health issues of concern. Investigators strove to provide opportunities for community participation in the various stages of research: study concept and design, data collection, data analysis and interpretation, conclusions, and dissemination of results. This article describes the involvement that community members had at each stage of the three forms of data collection and outlines the basic findings that led the Community Advisory Board to prioritize four areas for future work. In addition, it describes the challenges the project faced from the researcher perspective. Using examples from this experience, we conclude that this model may be an effective way for farm workers and their families to have a voice in prioritizing health and safety issues for research and action in their communities.

Normalizar y estandarizar el test MoCA, teniendo en cuenta las caracteristicas sociodemograficas de la poblacion española (datos INE, 2012). Sujetos y metodos. El estudio se enmarca dentro del proyecto Normacog, en el que se evaluo a 700 participantes (18-86 años). Se analizaron el efecto de la edad, el nivel educativo y el sexo sobre el rendimiento del test MoCA, y se crearon los percentiles, las puntuaciones escalares para nueve rangos de edad y la puntuacion escalar normalizada ajustada por edad y nivel educativo. Resultados. Los resultados mostraron un efecto significativo de la edad, el nivel educativo y el sexo sobre el rendimiento cognitivo en el test MoCA. Sin embargo, el sexo solo presento un efecto significativo sobre dos dominios cognitivos: atencion y recuerdo diferido. La edad, la educacion y el sexo explicaron entre el 1% y el 32,3% de la varianza en las variables analizadas del test. Los participantes mas mayores con menor nivel de educacion formal obtuvieron peor rendimiento cognitivo. Se obtuvieron los percentiles y las puntuaciones escalares para cada rango de edad y la puntuacion escalar normalizada individual. Conclusion. Se presentan los datos normativos del test MoCA adecuados a las caracteristicas sociodemograficas de la sociedad española y los puntos de corte propuestos para discriminar entre rendimiento cognitivo normal y deterioro cognitivo leve segun los diferentes rangos de edad.

    The purpose of this study was to analyze the diagnostic capacity of different classification criteria based on Body Mass Index in the assessment of nutritional status and to evaluate their effectiveness. The sample comprised 367 healthy pregnant adolescents in their first trimester of gestation, from a socioeconomic level IV, between Oct. 1999 and Dec. 2008. Two methodologies were applied for the nutritional classification: (1) Integral nutritional diagnosis (gold standard), and (2) Body Mass Index (BMI), using local reference values: Proyecto Venezuela and the Transversal Study of Caracas, and international reference values: Frisancho and WHO 2006. Concordances, kappa, sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios, and the Youden index were calculated. According to the gold standard and BMI, the percentage of well-nourished pregnant women ranged between 62.4% and 80.6%. Within the deficit range, Frisancho was the most effective with kappa: 0.80; sensitivity: 87.3%; specificity: 94.8%; positive likelihood ratio: 16.9, and negative likelihood ratio: 0.13; Youden index: 0.82. Within the excess range, Frisancho and the Transversal Study of Caracas were the most effective with Youden index: 0.86 and 0.83, respectively. These results revealed that Frisancho was the best criterion to diagnose malnutrition in deficit in pregnant women. All references have an adequate diagnostic capacity for the excess range, of which Frisancho and the Transversal Study of Caracas are the best. We recommend using such reference values to optimize the efficiency of the BMI indicator in diagnosing malnutrition in deficit and in excess in the first trimester of gestation in pregnant adolescents within populations with similar characteristics.

    Information on the management of myocardial infarction in Spain in scarce. PRIAMHO (Proyecto de Registro de Infarto Agudo de Miocardio Hospitalario) study is aimed at developing standardized methods to allow the registration of characteristics and management of patients discharged with a diagnosis of myocardial infarction. Methods and results of the pilot study are presented. In the present collaborative study with one-year follow-up, all patients diagnosed with myocardial infarction discharged from 33 Spanish hospitals are registered for one year including their demographic, clinical and outcome characteristics, as well as details on their management when admitted to a coronary care unit. Standardized definitions of diagnosis and measurements are used. Confidentiality of patients' identity and anonymous participation of each center are also warranted. The 33 participant coronary care units, covering some 10,000,000 people, admitted on average 83.9% of myocardial infarction patients of their hospital. In 16 participating centers there is a laboratory of hemodynamics and in 11 coronary surgery. During the pilot study, 606 patients were discharged from the participating coronary care units where the case-fatality, rate was 10.3%. While 19.8% of patients developed left heart failure, 44.1% received thrombolytic therapy. The delay between onset of symptoms and first monitoring was approximately 6 hours, and thereafter admission to the coronary unit about 3 hours. PRIAMHO study will allow to establish of the fundamentals for developing a nation-wide myocardial infarction register and will provide an accurate perspective of the characteristics and management of this disease in Spain.

Como parte del proyecto multicentrico Normacog, se administro el M-WCST a 700 participantes (rango: 18-90 años). Se analizaron el efecto de la edad, el nivel educativo y el sexo sobre el M-WCST, y se crearon percentiles y puntuaciones escalares calibradas demograficamente para cada puntuacion directa. Resultados. Se observo un efecto significativo de la edad y del nivel educativo sobre las variables analizadas del M-WCST (categorias correctas, errores perseverativos y errores totales), pero no un efecto significativo del sexo en ninguna de las variables. La edad y la educacion explicaban un 5,0-21,2% de la varianza en el M-WCST y mostraron que, a mayor edad y menor nivel de educacion formal, el numero de categorias correctas disminuia y se cometian mayor cantidad de errores. Conclusion. El presente estudio aporta por primera vez los baremos normativos del M-WCST para la poblacion española teniendo en cuenta las caracteristicas sociodemograficas de nuestra sociedad. Se confirma la influencia de la edad y el nivel educativo sobre el rendimiento del M-WCST.

    Background: Polybrominated diphenyl ethers (PBDE), which are used as flame retardants, have been found to be higher in residents of California than of other parts of the United States. Objectives: We aimed to investigate the role of immigration to California on PBDE levels in Latino children. Methods: We compared serum PBDE concentrations in a population of first-generation Mexican-American 7-year-old children (n = 264), who were born and raised in California [Center for Health Analysis of Mothers and Children of Salinas (CHAMACOS) study], with 5-year-old Mexican children (n = 283), who were raised in the states in Mexico where most CHAMACOS mothers had originated (Proyecto Mariposa). Results: On average, PBDE serum concentrations in the California Mexican-American children were three times higher than their mothers’ levels during pregnancy and seven times higher than concentrations in the children living in Mexico. The PBDE serum concentrations were higher in the Mexican-American children regardless of length of time their mother had resided in California or the duration of the child’s breast-feeding. These data suggest that PBDE serum concentrations in these children resulted primarily from postnatal exposure. Conclusions: Latino children living in California have much higher PBDE serum levels than their Mexican counterparts. Given the growing evidence documenting potential health effects of PBDE exposure, the levels in young children noted in this study potentially present a major public health challenge, especially in California. In addition, as PBDEs are being phased out and replaced by other flame retardants, the health consequences of these chemical replacements should be investigated and weighed against their purported fire safety benefits.

    Community-researcher partnerships can be powerful mechanisms to understand and effectively address health and social problems such as HIV/AIDS prevention. When the partnership is a positive, productive one, the combined expertise and energy of both parties result in a more effective program and a better evaluation of its effects. This article describes one such partnership and how a program challenge provided the opportunity for both partners to develop new capacities and strengthen others. The program is Proyecto SOLAAR, a community-based and culturally-sensitive HIV prevention program for gay and bisexual Latino men. The program is an experiential, daylong retreat focused on personal aspects of the men (e.g., self-concept), ideas about and aspects of their relationship behavior (e.g., cultural misunderstandings, dating behavior), and HIV prevention; there is a follow-up reunion a month later to share experiences with other participants about new dating and HIV prevention behaviors. The article focuses in particular on how the partners built new capacity in the area of social marketing to address the challenge of participant recruitment and describes the components of the new campaign. These components included distinctive images in ads in publications read by the target population, a toll-free telephone number and Web site for easy initial contact with the program, phone cards and postcards featuring the specially created program image to reinforce a connection to the program, and other aspects. The article describes the partnership between the HIV service providers and the researchers and how the collaborative effort was key to understanding and addressing the recruitment problem, identifying potential solutions, and implementing the new social marketing strategy. This process resulted in four kinds of capacities that were built or strengthened, including program recruitment, program content and implementation, program evaluation, and the partnership itself.

    RESUMEN La comunicación sobre sexualidad entre padres/madres y adolescentes enfrenta dificultades particulares producto de factores socioculturales. Este estudio tuvo como objetivo documentar las actitudes de padres/madres y adolescentes hacia la comunicación sobre temas de sexualidad. Los resultados emanan de la medición inicial del Proyecto Cuídalos. Los datos de este estudio forman parte de un estudio amplio que evaluó un módulo interactivo basado en la web para mejorar comunicación sobre temas de salud entre padres/madres y adolescentes entre 13–17 años. En este artículo, reportamos datos basales que contestaron los/as participantes sobre comodidad al hablar sobre temas de salud sexual. La muestra, de los datos aquí expuestos, estuvo compuesta por 458 diadas de madres/padres y sus hijos/as adolescentes (n=916). Se realizó análisis de frecuencias y medidas de tendencia central con los datos obtenidos inicialmente. La edad promedio de los adolescentes fue de 15 años, de los que un 15% se encontraban activos sexualmente. Los/as adolescentes tienen mejor disposición que los/as padres/madres para hablar sobre sexualidad. Sin embargo, los/as padres/madres entienden que comparten suficiente información sobre temas relacionados a la sexualidad. Los/as padres/madres y adolescentes reportaron algún grado de dificultad e incomodidad al hablar sobre métodos específicos de prevención. Los resultados destacan la necesidad de incorporar a los/as padres/madres en intervenciones con adolescentes sobre temas de salud sexual. En Puerto Rico es necesario desarrollar programas dirigidos a minimizar las conductas sexuales de alto riesgo en jóvenes. PMID:28736599

    Objectives Prenatal psychosocial stress has been associated with adverse pregnancy outcomes, even after controlling for known risk factors. This paper aims to evaluate correlates of high perceived stress among Hispanic women, a group with elevated rates of stress during pregnancy. Methods We conducted this analysis among 1426 pregnant Hispanic women using data from Proyecto Buena Salud, a prospective cohort study conducted in Western Massachusetts. Cohen’s Perceived Stress Scale (PSS-14) validated in English and Spanish was administered in early (mean=12.4 wks gestation), mid (mean=21.3 wks gestation) and late (mean=30.8 wks gestation) pregnancy at which time bilingual interviewers collected data on socio-demographic, acculturation, behavioral, and psychosocial factors. High perceived stress was defined as a PSS score>30. Results Young maternal age (odds ratio (OR) =0.6; 95% confidence interval (CI) 0.4-0.9 for <19 vs. 19-23yrs), pre-pregnancy consumption of alcohol (OR=2.2; 95% CI 1.4-3.5 for >12 drinks/mo. vs. none) and smoking (OR=2.2; 95% CI 1.3-3.7 for >10 cigarettes/day vs. none) were associated with high perceived stress during early pregnancy. Furthermore, higher annual household income (OR=0.4; 95% CI 0.1-0.9 for >$30,000 vs. <$15,000), greater number of adults in the household (OR=1.8; 95% CI 1.1-3.0 for ≥3 vs. 1) and language preference (OR=0.6; 95% CI 0.4-0.9 for Spanish vs. English) were associated with high stress during mid-pregnancy. Likewise, annual household income was inversely associated with high stress during late pregnancy. Conclusion Our results have important implications for incorporation of routine screening for psychosocial stress during prenatal visits and implementation of psychosocial counseling services for women at high risk.

    The urban and periurban area of Copiapó in the arid Atacama desert has more than 30 abandoned mine tailings, one active copper smelter, and 150,000 inhabitants. Fast development of the mining industry during the 19th century and unplanned growth has led to public concern about the presence of metals in soils and street dust. Recent floods and mud currents in the Copiapó watershed have introduced new solid material in about 40% of the urban area. We conducted a geochemical screening before and after the disaster in March 2015. We found concentrations as high as 1000 mg/kg of copper and 180 mg/kg of arsenic in urban soils. Since effective control measures require connecting sites of metal enrichment with the possible sources, we have performed a statistical analysis of metal association and complemented it with other analyses like x-ray diffraction. Cluster analyses of elemental compositions suggest that mud and tailing have different origins from the rest of the matrices, while soils and street dust have a similar one. Some clusters have a mix of matrices that suggest anthropogenic enrichment of some areas of Copiapó. Our initial results indicate that a correlation between observed enrichment and the copper smelter can be hypothesized for Cu, Pb, and Zn. Further spatial, statistical, and chemical analyses are needed to further confirm such findings, complemented with a thorough analysis of the baseline values that could be considered representative of the area. Future work include Principal Component Analysis (PCA) and Positive matrix factorization (PMF) to test the link contaminant sources and metal occurrence, while scanning electron microscopy can be used to identify the presence of smelter-related particles. The information generated by this research will be a necessary input for defining urban planning strategies and land use guidelines, defining health risk assessment studies, and for future evaluation of intervention priorities.

    In the context of a public health-oriented drug policy reform in Mexico, we assessed the spatial distribution of police encounters among people who inject drugs (PWID) in Tijuana, determined the association between these encounters and the location of addiction treatment centers and explored the association between police encounters and treatment access. Geographically weighted regression (GWR) and logistic regression analysis using prospective spatial data from a community-recruited cohort of PWID in Tijuana and official geographical arrest data from the Tijuana Municipal Police Department. Tijuana, Mexico. A total of 608 participants (median age 37; 28.4% female) in the prospective Proyecto El Cuete cohort study recruited between January and December 2011. We compared the mean distance of police encounters and a randomly distributed set of events to treatment centers. GWR was undertaken to model the spatial relationship between police interactions and treatment centers. Logistic regression analysis was used to investigate factors associated with reporting police interactions. During the study period, 27.5% of police encounters occurred within 500 m of treatment centers. The GWR model suggested spatial correlation between encounters and treatment centers (global R(2)  = 0.53). Reporting a need for addiction treatment was associated with reporting arrest and police assault [adjusted odds ratio = 2.74, 95% confidence interval (CI) = 1.25-6.02, P = 0.012]. A geospatial analysis suggests that, in Mexico, people who inject drugs are at greater risk of being a victim of police violence if they consider themselves in need of addiction treatment, and their interactions with police appear to be more frequent around treatment centers. © 2016 Society for the Study of Addiction.

    Living donor kidney (LKD) transplantation provides better results than deceased donor donation, involving minimum risk for the donor. However, LKD donation rates are low in most countries. We analyzed attitudes toward LKD in transplant hospitals in Spain, Mexico, and Cuba. Data were obtained from five transplant hospitals through the International Collaborative Program "Proyecto Donante Vivo, Murcia" in three countries: Spain (n = 1168), Mexico (n = 903), and Cuba (n = 202). The random sample (2273 employees) was stratified according to job category. The instrument used to evaluate attitude was a validated questionnaire. Statistical analysis included Student t test, the chi(2) test, and multivariate analysis. Eighty eight percent (n = 2002) of Spanish, Mexican, and Cuban transplant hospital personnel were in favor of related LKD and 24% nonrelated LKD (n = 555). Attitudes were more favorable among centers in Cuba 97% (n = 195), followed by Mexico 88% (n = 793) and by Spain 87% (n = 1014; P < .001). According to job category, 91% (n = 617) of physicians were in favor, 88% (n = 543) of nurses, 85% (n = 198) of health care assistants, and 85% (n = 198) of auxiliary personnel. Attitudes were related to variables of: attitude toward deceased donation (P < .001), discussion about organ donation and transplantation (P < .001), concern about body mutilation after donation (P = .001), a possible need for a transplant in the future (P < .001), and attitude toward living liver donation (P < .001). Attitudes toward LKD in Hispanic/Latin Transplant Hospitals were favorable and could encourage an increase in LKD in the coming years assuming suitable sociopolitical and economic condition, as well as support from nephrologists.

    Non-medical staff members in hospitals are highly credible at population level, and are a source of opinion even though they do not have sufficient medical training. To analyse the attitudes of non-medical professionals of Spanish and Latin American hospitals towards organ donation and identify the factors that influence these attitudes. Through the "Proyecto Colaborativo Internacional Donante" (International Collaborative Donor Project), a stratified random sample was selected from non-medical services of eleven hospitals: 3 Spanish (n=277), 5 Mexican (n=632), 2 Cuban (n=42) and 1 Costa Rican (n=101). Of the 1052 professionals surveyed, 72% (n=754) were in favour of donating an organ after death. By country, 98% of Cubans, 80% of Mexicans, 66% of Costa Ricans and 52% of Spanish were in favour (P<.001). The most influential variables were: 1) country, with results being more positive in Mexico (odds ratio [OR]=2.197), 2) believing in the possibility that they will require a transplant (OR=2.202), 3) having discussed the issue with their family (OR=3.23), 4) the positive attitude of their partner towards donation (OR=3.322), 5) not being concerned about possible mutilation of their body after donation (OR=3.378), 6) preferring options other than burial (OR=2.525), 7) accepting an autopsy (OR=2.958). The attitude of non-medical staff members of hospitals towards the donation of their own organs varies greatly depending on the country of the respondent. Psychosocial factors that influence these attitudes are similar to those described at the population level.

    The importance of hydrologic-geochemical interactions in arid environments is a controlling factor in quality and quantity of water available for human consumption and agriculture. When acid drainage affects these watersheds, water quality is gravely degraded. Despite its effect on watersheds, the relationship between time changes in hydrological variables and water quality in arid regions has not been studied thoroughly. Temporal variations in acid drainage can control when the transport of toxic elements is increased. We performed field work at the Azufre River (pH 2, E.C~10.9 mS/cm) and Caracarani River (pH 8.7, E.C~1.2 mS/cm) confluence, located in the Northern Chilean Altiplano (at 4000 m asl). We registered stream flowrates (total flowrate~430 L/s), temperature and electric conductivity (E.C) hourly using in-stream data loggers during one year. We also measured turbidity and pH during one field survey at different distances from the junction, as a proxy of the formation of iron-aluminum particles that cycle trace elements in these environments. We found turbidity-pH diurnal cycles were caused by upstream hourly changes in upstream flowrate: when the Caracarani River flowrate reached its daily peak, particle formation occurred, while the dissolution of particles occurred when the Azufre River reached its maximum value. This last process occurred due to upstream freeze-thaw cycles. This study shows how the dynamics of natural confluences determines chemical transport. The formation of particles enriched in toxic elements can promote settling as a natural attenuation process, while their dissolution will produce their release and transport long distances downstream. It is important to consider time as an important variable in water quality monitoring and in water management infrastructure where pulses of contamination can have potentially negative effects in its use.

    On March 3, 2015 Villarrica Volcano underwent an abrupt change in volcanic behavior that culminated in a large fire fountaining event lasting 30 minutes that prompted the evacuation of residents within 9 km from the vent. This paroxysm was the first in 30 years and changed summit morphology by temporarily capping the previously stable lava lake with volcanic material. After March 3, Villarrica exhibited a period of quiescence before reactivating with various levels of ash venting associated with strombolian style activity. Ten infrasound arrays, each comprising three pressure transducers, were deployed in January and February that recorded until mid June and serendipitously chronicled the awakening, paroxysm, and recovery to a more open vent system typical to Villarrica. Coincidentally, several optical datasets were gathered. Time lapse photography, provided by Proyecto Observacion Villarrica Internet (POVI), recorded vent activity at an interval of ~15 seconds with a 240 mm zoom lens at 16 km from the vent, starting December 2014 until March 12, 2015. Additionally, video footage of the vent was recorded at 30 frames per second (fps) with a 50 mm lensed surveillance camera between March 4 and June of 2015 at a distance of 16 km from the vent. The combined infrasound and image processing approach offers novel insight into the various acoustic signatures of a dynamic and violent volcanic system. Video parameters, including plume color, ascent rate, and duration of venting are synthesized as time series. These video metrics of vent activity are then quantitatively compared to the corresponding infrasound waveform. The result is the classification of several different infrasound modes of activity during the diverse eruptive sequence of Villarrica between January and June of 2015.

    Aim Prior literature suggests a positive association between psychosocial stress and the risk of diabetes in non-pregnant populations, but studies during pregnancy are sparse. We evaluated the relationship between stress and glucose intolerance among 1115 Hispanic (predominantly Puerto Rican) prenatal care patients in Proyecto Buena Salud, a prospective cohort study in Western Massachusetts (2006–2011). Methods Cohen’s Perceived Stress Scale (PSS-14) was administered in early (mean = 12.3 weeks gestation; range 4.1–18 weeks) and mid-(mean = 21.3 weeks gestation; range 18.1–26 weeks) pregnancy. Participants were classified as having a pregnancy complicated by gestational diabetes mellitus, impaired glucose tolerance, and abnormal glucose tolerance, based on the degree of abnormality on glucose tolerance testing between 24 and 28 weeks of gestation. Results The prevalence of gestational diabetes mellitus, impaired glucose tolerance, and abnormal glucose tolerance was 4.1%, 7.2%, and 14.5%, respectively. Absolute levels of early or mid-pregnancy stress were not significantly associated with glucose intolerance. However, participants with an increase in stress from early to mid-pregnancy had a 2.6-fold increased odds of gestational diabetes mellitus (95% confidence intervals: 1.0–6.9) as compared to those with no change or a decrease in stress after adjusting for age and pre-pregnancy body mass index. In addition, every one-point increase in stress scores was associated with a 5.5 mg/dL increase in screening glucose level (β = 5.5; standard deviation = 2.8; P = 0.05), after adjusting for the same variables. Conclusion In this population of predominantly Puerto Rican women, stress patterns during pregnancy may influence the risk of glucose intolerance. PMID:24948416

    Introduction Latinas in the United States on average have poorer birth outcomes than Whites, yet considerable heterogeneity exists within Latinas. Puerto Ricans have some of the highest rates of adverse outcomes and are understudied. The goal of this study was to determine if acculturation was associated with adverse birth outcomes in a predominantly Puerto Rican population. Methods We conducted a secondary analysis of Proyecto Buena Salud, a prospective cohort study conducted from 2006 to 2011. A convenience sample of pregnant Latina women were recruited from a tertiary care hospital in Massachusetts. Acculturation was measured in early pregnancy; directly via the Psychological Acculturation Scale, and via proxies of language preference and generation in the United States. Birth outcomes (gestational age and birthweight) were abstracted from medical records (n = 1362). Results After adjustment, psychological acculturation, language preference, and generation was not associated with odds of preterm birth. However, every unit increase in psychological acculturation score was associated with an increase in gestational age of 0.22 weeks (SE = 0.1, p = 0.04) among all births. Women who preferred to speak Spanish (β = -0.39, SE = 0.2, p = 0.02) and who were first generation in the US (β = -0.33, SE = 0.1, p = 0.02) had significantly lower gestational ages than women who preferred English or who were later generation, respectively. Similarly, women who were first generation had babies who weighed 76.11 g less (SE = 35.2, p = 0.03) than women who were later generation. Discussion We observed a small, but statistically significant adverse impact of low acculturation on gestational age and birthweight in this predominantly Puerto Rican population.

Métodos: Se evaluaron las reacciones adversas a medicamentos (RAM) de los pacientes pediátricos trasplantados renales y hepáticos de nuestro hospital tratados con inhibidores de calcineurina (ciclosporina y tacrolimus) por revisión retrospectiva de historias clínicas de pacientes trasplantados en 2010-2011, y análisis prospectivo por farmacovigilancia activa de trasplantados fuera de dicho período, cuyas complicaciones se hayan presentado en los ateneos semanales del Servicio de Trasplante desde marzo de 2011. Las RAM se notificaron a la autoridad sanitaria nacional. Resultados: Se analizaron un total de 59 pacientes, 28 trasplantados renales y 31 hepáticos. Se notificaron, en ambos trasplantes, 60 RAM a ciclosporina destacándose (número de casos) hipertensión arterial (19) y nefrotoxicidad (6). Asimismo, se registraron 46 RAM a tacrolimus, incluyendo hipomagnesemia (25), hipertensión (7) y nefrotoxicidad (5). El 95% y 96% de los eventos adversos a ciclosporina y a tacrolimus, respectivamente, han sido agrupados como probables o definitivos. El 70% y 98% de los eventos adversos a ciclosporina y a tacrolimus respectivamente, han sido de severidad moderada o grave. Conclusiones: Este es el primer proyecto en América Latina que propone y desarrolla el estudio cuali-cuantitativo intensivo de RAM a inhibidores de calcineurina en trasplante pediátrico renal y hepático. Es necesario estimular la notificación espontánea así como continuar el seguimiento de RAM a mediano y largo plazo para mejorar la calidad de vida del paciente trasplantado.

  9. Using connectivity to assess soil erosion in the landscape; applications of a new paradigm in soil erosion modelling

    2013-04-01

    Hydrologic and sedimentological connectivity concepts recently appeared as novel paradigms (Bracken and Croke , 2007) and tools to assess soil erosion at various scales. The landscape flow connectivity index IC (Borselli et al. 2007, 2008) is based on the ratio of hydrological distance to streams with the potential upstream runoff occurrence, hence allows mapping surface runoff connectivity and erosion across the landscape. After its first introduction, several studies applied the IC algorithm in very different geographic regions and territorial scale: 150 km2 watershed in Tuscany (Italy; Borselli et al. 2007, 2008); 20 small catchments (5 to 350 ha) in Murcia (Spain; Sougnez et al. 2011); 400 km2 watershed in Basilicata (South Italy; Borselli et al. 2011); 3300 km2 watershed in Victoria (Australia; Vigiak et al. 2012); 6 and 8 km2watersheds in the Italian Alps (Cavalli et al., in press); 74 ha catchment in Spanish Pre-Pyrenees (López-Vicente et al. 2013). Meanwhile, the IC index has been adapted for application to different erosion processes, i.e. hillslope erosion (Vigiak et al. 2012; López-Vicente et al. 2013), sediment remobilization by shallow landslides (Borselli et al. 2011), and debris flow (Cavalli et al. in press). Validation of IC index applications in spatially distributed erosion models has been conducted with field observations at hillslope scale, calibration against sediment yield estimates at several monitoring stations. These scientific results highlight the promising potential application of IC concept for erosion modelling. In this session, the IC model with all its proposed variants will be described. Future work perspectives, including potential developments of IC approach as an alternative method to classical soil erosion modelling, will be discussed.

    We occasionally include projects in our learner-centered introductory astronomy college course to enable non-science major students explore some astronomical concepts in more detail than otherwise. Such projects also highlight ongoing or upcoming astronomical events. We hope that students will feel more interested in astronomy through projects tied to astronomical events. In Spring 2012, we offered short essays focused on eclipses, transits and occultations to promote the rare transit of Venus that occurred on June 5th, 2012. We asked students to write two short essays from three that were offered. The essays contained descriptive and conceptual parts. They were meant to serve as teaching tools. 62% of 106 essays from 55 students earned A, B or C grades. 21% of 47 feedback survey respondents felt the essays increased their interest in astronomy. 49% of respondents felt that the essays were not educationally beneficial and should not be offered again. The most common written response to our survey indicated that students need more guidance and better preparation in writing successful essays. Since students found the conceptual parts of the essays difficult, in the future we will provide relevant activities prior to essay deadlines to help students create successful essays.

    Introducción: Intervención piloto en nutrición y actividad física para prevenir obesidad en la educación preescolar (cerca de medio millón de niños en Chile). Objetivo: Evaluar los resultados primarios (grasa corporal) y secundarios (actividad física e ingesta energética) de una intervención piloto para niños/as asistentes a guarderías infantiles. Métodos: Intervención piloto en seis guarderías seleccionadas al azar (n = 530 preescolares), 4-5 años en Santiago de Chile, con el objeto de: a) proporcionar educación en nutrición y actividad física para los educadores; b) actividades de promoción de la salud para la familia. El objetivo primario (grasa corporal), y los resultados secundarios (patrón de actividad física y la ingesta energética) se midieron en 265 preescolares (120 intervenidos y 145 niños controles). Resultados: La actividad física moderada- intensa se duplicó en los intervenidos (+5,4% y +4,7%, respectivamente), tanto en niños obesos y eutróficos. La ingesta energética se redujo en 11,7% en obesos y 7,5% en los eutróficos y la de grasa en (-11 g en obesos y -8,4 g en niños eutróficos). Los niños obesos intervenidos redujeron la grasa corporal en 1,5%, mientras que en los niños controles obesos, se incrementó 1,3% (p < 0,01). Conclusiones: La intervención piloto demostró la viabilidad de influir en los factores de riesgo dietarios y de actividad física en las guarderías y en las familias. Por lo tanto, la ejecución del proyecto piloto se pondrá a prueba en diferentes condiciones climáticas, para prevenir hábitos no saludables en los preescolares y sus familias.

  14. The IAC Stripe 82 Legacy Project: a wide-area survey for faint surface brightness astronomy

    2016-02-01

    We present new deep co-adds of data taken within Stripe 82 of the Sloan Digital Sky Survey (SDSS), especially stacked to reach the faintest surface brightness limits of this data set. Stripe 82 covers 275 ° ^2 within -50° ≤ RA ≤ +60° and -1.25° ≤ Dec. ≤ +1.25°. We discuss the steps of our reduction which puts special emphasis on preserving the characteristics of the background (sky + diffuse light) in the input images using a non-aggressive sky subtraction strategy. Our reduction reaches a limit of ˜28.5 mag arcsec-2 (3σ, 10 × 10 arcsec2) in the r band. The effective surface brightness limit (50 per cent completeness for exponential light distribution) lies at <μe(r)> ˜ 25.5 mag arcsec-2. For point sources, we reach 50 per cent completeness limits (3σ level) of (24.2, 25.2, 24.7, 24.3, 23.0) mag in (u, g, r, i, z). This is between 1.7 and 2.0 mag deeper than the single-epoch SDSS releases. The co-adds show point spread functions (PSFs) with median full width at half-maximum values ranging from 1 arcsec in i and z to 1.3 arcsec in the u band. The imaging data are made publicly available at http://www.iac.es/proyecto/stripe82. The release includes deep co-adds and representations of the PSF for each field. Additionally, we provide object catalogues with stars and galaxies confidently separated until g ˜ 23 mag. The IAC Stripe 82 co-adds offer a rather unique possibility to study the low surface brightness Universe, exemplified by the discovery of stellar streams around NGC 0426 and NGC 0936. We also discuss further science cases like stellar haloes and disc truncations, low surface brightness galaxies, the intracluster light in galaxy clusters and the diffuse emission of Galactic dust known as Galactic Cirrus.

    Introducción: a finales del siglo xx, no se conocía con precisión si la comida del comedor escolar contribuía adecuadamente a la dieta de la población infantil. Además, este servicio complementario no se contemplaba en el proyecto educativo del centro pese a considerarse fundamental en todas sus dimensiones.Objetivo: describir el origen y desarrollo del programa de comedores escolares de la Comunidad de Madrid (CM) en 15 años desde su implantación.Métodos: se elaboró una normativa a cumplir por las empresas de restauración, y que contemplaba aspectos nutricionales y de composición y variedad de los menús, que se utilizó en los concursos para acceder a la prestación del servicio de comedor escolar, publicados en los años 2001, 2002, 2005, 2009 y 2013. Además se realizaron visitas acreditadas a los centros sin previo aviso para verifi car el cumplimiento de la documentación aportada durante el concurso.Resultados: los criterios más actuales sobre programación y elaboración de menús escolares se recogen en el Pliego de Prescripciones Técnicas del año 2013 (C-504/001-2013). Un 92% de las empresas de restauración superaron los cinco concursos habidos en los 15 años de funcionamiento. Hasta el año 2014, se han realizado 755 visitas, revisándose un total de 574 centros.Conclusiones: el programa de comedores escolares de la CM, desde su implementación pionera en España, ha contribuido a la mejora del servicio complementario de comedor. En estos años se han ido incluyendo nuevos requisitos dietéticos y nutricionales que han logrado menús cada vez más ajustados a las recomendaciones de la población escolar.

    The paucity of data on myocardial infarction management and results in Spain lead to the design of the PRIAMHO study (Proyecto de Registro de Infarto Agudo de Miocardio Hospitalario [Acute Myocardial Infarction Hospital Registration Project]) which developed standard methods to collect information on the management of patients with such a condition and their characteristics. The variability results among hospitals in myocardial infarction management and in one-year mortality are presented. A cohort study with a one-year follow-up was designed to register all patients diagnosed with acute myocardial infarction discharged from 24 Spanish hospitals that completed all the requisites to participate. The demographic and clinical characteristics of the patients, their management during the coronary care unit stage, and the outcome and complications were prospectively registered. Standard definitions for diagnosis were used. Confidentiality regarding patient identity and participating centers was guaranteed. 5,242 (77.6%) of the 6,756 patients with myocardial infarction admitted in the 24 participating hospitals were registered in the coronary care units. Half of the centers had an on-site hemodynamic laboratory and in seven coronary surgery. The delay between symptom-onset and emergency room admission was 2 hours. Acute pulmonary edema or cardiogenic shock was developed by 16.6% of patients and 41.8% received thrombolysis. Mean time delay between symptom-onset and thrombolysis was 3 hours. A large variability in the use of beta-blockers, thrombolysis, echocardiography, coronary catheterization angiography and invasive revascularization was observed among hospitals. Mortality in the coronary care unit was 10.9% and increased to 14.0% at 28 days and to 18.5% at one year with considerable variation among hospitals. Four hospitals showed higher mortality among their patients, independently from the proportion of diabetes, hypertension, women, anterior location of myocardial

    Policymakers and researchers seek answers to how liberalized drug policies affect people who inject drugs (PWID). In response to concerns about the failing "war on drugs," Mexico recently implemented drug policy reforms that partially decriminalized possession of small amounts of drugs for personal use while promoting drug treatment. Recognizing important epidemiologic, policy, and socioeconomic differences between the United States-where possession of any psychoactive drugs without a prescription remains illegal-and Mexico-where possession of small quantities for personal use was partially decriminalized, we sought to assess changes over time in knowledge, attitudes, behaviors, and infectious disease profiles among PWID in the adjacent border cities of San Diego, CA, USA, and Tijuana, Baja California, Mexico. Based on extensive binational experience and collaboration, from 2012-2014 we initiated two parallel, prospective, mixed methods studies: Proyecto El Cuete IV in Tijuana (n = 785) and the STAHR II Study in San Diego (n = 575). Methods for sampling, recruitment, and data collection were designed to be compatible in both studies. All participants completed quantitative behavioral and geographic assessments and serological testing (HIV in both studies; hepatitis C virus and tuberculosis in STAHR II) at baseline and four semi-annual follow-up visits. Between follow-up assessment visits, subsets of participants completed qualitative interviews to explore contextual factors relating to study aims and other emergent phenomena. Planned analyses include descriptive and inferential statistics for quantitative data, content analysis and other mixed-methods approaches for qualitative data, and phylogenetic analysis of HIV-positive samples to understand cross-border transmission dynamics. Investigators and research staff shared preliminary findings across studies to provide feedback on instruments and insights regarding local phenomena. As a result, recruitment and data

    The Proyecto Epidemiológico Guanacaste (PEG) has conducted several large studies related to human papillomavirus (HPV) and cervical cancer in Guanacaste, Costa Rica in a long-standing collaboration with the U.S. National Cancer Institute. To improve molecular epidemiology efforts and save costs, we have gradually transferred technology to Costa Rica, culminating in state-of-the-art laboratories and a biorepository to support a phase III clinical trial investigating the efficacy of HPV 16/18 vaccine. Here, we describe the rationale and lessons learned in transferring molecular epidemiologic and biorepository technology to a developing country. At the outset of the PEG in the early 1990s, we shipped all specimens to repositories and laboratories in the United States, which created multiple problems. Since then, by intensive personal interactions between experts from the United States and Costa Rica, we have successfully transferred liquid-based cytology, HPV DNA testing and serology, chlamydia and gonorrhea testing, PCR-safe tissue processing, and viable cryopreservation. To accommodate the vaccine trial, a state-of-the-art repository opened in mid-2004. Approximately 15,000 to 50,000 samples are housed in the repository on any given day, and >500,000 specimens have been shipped, many using a custom-made dry shipper that permits exporting >20,000 specimens at a time. Quality control of shipments received by the NCI biorepository has revealed an error rate of <0.2%. Recently, the PEG repository has incorporated other activities; for example, large-scale aliquotting and long-term, cost-efficient storage of frozen specimens returned from the United States. Using Internet-based specimen tracking software has proven to be efficient even across borders. For long-standing collaborations, it makes sense to transfer the molecular epidemiology expertise toward the source of specimens. The successes of the PEG molecular epidemiology laboratories and biorepository prove that

    NASA has three satellite tracking stations around the world: CDSCC (Canberra, Australia), GDSCC (Goldstone, USA) and MDSCC (Madrid, Spain). One of the antennas located at MDSCC, DSS-61, is not used for satellite tracking any more and thanks to an agreement between INTA (Instituto Nacional de TA~l'cnica Aeroespacial) and NASA, it has been turned into an educational radio telescope. PARTNeR (Proyecto Académico con el RadioTelescopio de NASA en Robledo, Academic Project with the NASA Radio Telescope at Robledo) is a High School and University radio astronomy educational program that allows teachers and students to control this 34-meter radio telescope and conduct radio astronomical observations via the Internet. As radio astronomy is not a popular subject and astronomy has little presence in the High School Curriculum, teachers need specific training in those subjects to implement PARTNeR. Thus, High School teachers joining the project take a course to learn about the science of radio astronomy and how to use the antenna in their classrooms. Also, teachers are provided with some learning activities they can do with their students. These lesson plans are focused on the implementation of the project within an interdisciplinary framework. All educational resources are available on PARTNeR website. PARTNeR is an inquiry based approach to science education. Nowadays, students can join in three different observational programmes: variability studies in quasars, studies of radio-bursts in X-ray binaries (microquasars), and mapping of radio sources in the galactic plane. Nevertheless, any other project can be held after an evaluation by the scientific committee. The operational phase of the project started in the academic year 2003-04. Since then, 85 High Schools, seven Universities and six societies of amateur astronomers have been involved in the project. During the 2004-09 period, 103 High School teachers from Spain and Portugal have attended the training courses, and 105

Estas condiciones pueden tener consecuencias en la edad adulta. Objetivo: determinar la prevalencia de riesgo cardiovascular y factores asociados en las tres fases de la adolescencia. Métodos: estudio transversal que incluye a adolescentes de 10-19 años en la ciudad de Viçosa, distribuidos en tres fases. Se evaluaron las pruebas de laboratorio, el índice de masa corporal clasificadas en Z-score, según el sexo y la edad, y el porcentaje de grasa corporal, clasificados por sexo. Se utilizó la prueba de chi-cuadrado, la partición de chi-cuadrado con corrección de Bonferroni y la regresión de Poisson. El nivel de significación fue < 0,05. El proyecto fue aprobado por el Comité de Ética en Investigación de la UFV en humanos. Resultados: el sobrepeso, la grasa corporal, el perfil lipídico, el comportamiento sedentario y la historia de enfermedades cardiovasculares en la familia fueron los factores de riesgo cardiovascular más prevalentes entre los adolescentes. Los adolescentes tenían tasas más altas de sobrepeso y grasa. En cuanto a las etapas, la inicial mostró un mayor porcentaje de individuos con comportamiento sedentario, sobrepeso y colesterol total y LDL en comparación con otras fases. Los individuos con cambios en el estado nutricional eran más propensos a desarrollar hipertensión, cambios en el colesterol total, LDL, triglicéridos, insulina, HOMA y HDL bajo, en comparación con los individuos sanos. Conclusiones: los factores de riesgo cardiovascular se han observado en personas cada vez más jóvenes y son factores importantes para identificar una población en riesgo.

Les résultats ont indiqué que l'optimisme dispositionnel était plus fort chez les américains en comparaison aux participants jordaniens. Des analyses séparées de l'optimisme versus le pessimisme ont montré que les participants jordaniens n'étaient pas pessimistes mais pas moins optimistes que leurs homologues américains. Il n'y avait pas de corrélations significatives entre l'optimisme dispotionnel et le sexe, le statut socio-économique et la religiosité. Les niveaux d'optimisme dispotionnel affichés par les jordaniens dans cette étude sont inconsistents avec les affirmations passées d'un occident optimiste et d'un orient pessimiste et suggèrent que les processus d'auto-amélioration pourraient ne pas être restreints aux occidentaux ou aux groupes hautement individualistes. Les résultats n'ont pas dévoilé une association entre l'optimise dispotionnel et les comportements de risque ou les comportements d'auto-protection. Des analyses de régression multiples ont indiqué que le contexte culturel et le sexe sont les meilleurs prédicteurs de ces comportements. Les implications de ces résultats sont discutées. El presente estudio se basó en la evaluación de algunas conclusiones de investigaciones anteriores, basadas principalmente en comparaciones de habitantes de norteamericanos con habitantes del Asia del este, en las que se proponía que mientras los occidentales tienden a ser optimistas, los orientales tienden a ser pesimistas. En dos muestras de estudiantes de la escuela superior europeo-americanos y jordanos se administró un cuestionario que consiste en preguntas que miden el optimismo disposicional junto con preguntas que evalúan conductas de riesgo y de autoprotección (p.e., uso de cinturón de seguridad, velocidad de manejo, fumar

    are still being processed. Nevertheless, preliminary results indicated that addition of biochar did not alter negatively physical properties (pH, EC) or composition of this alkaline soil, on the contrary biochar addition caused a slight improvement of the WHC and soil porosity. Those changes produced a faster development of plant shoots. However, at the end of the experiment, biochar amendment caused no significant increase on the agronomic production for any of the tested biochars. From these preliminary results, we conclude that biochar amendment improved physical-surficial characteristics of the calcic Cambisol from an agronomic point of view, but under the typical Mediterranean climate those changes seem to leave the harvested seed yields unaffected.

    The aim of this paper is to present a project developed through a partnership between the Astronomy Club of Itaocara Marcos Pontes (CAIMP) and Jaime de Souza Queiroz College, both located in the town of Itaocara, in the Northwest Fluminense, to disseminate Astronomy in adult education (Education for Youth and Adult). Given the interdisciplinary nature of Astronomy, we have developed this work to motivate the learning of this science by students in adult education, who attend the subjects Chemistry, Physics and Biology. Initially, we conducted a research in the school to assess the prior knowledge of Astronomy class of adult education, noting that there is little knowledge of basic concepts of the discipline. With these data, we were able to elaborate several activities that would enable a greater involvement of students with this science, performing in the school a work of improvement of scientific literacy, whose activities will be presented in this article. El objetivo de este artículo es presentar los resultados de un proyecto realizado por el Club de Astronomía de Itaocara "Marcos Pontes" (CAIMP), conjuntamente con el Colegio Estatal" Jaime de Souza Queiroz", ambos de la ciudad de Itaocara (Noroeste Fluminense - RJ, Brasil), para la difusión de la Astronomía entre los estudiantes, tanto adultos como adolescentes. Teniendo en cuenta la naturaleza interdisciplinaria de la Astronomía, se determinó motivar el estudio de esta ciencia en los estudiantes adultos de nivel secundario matriculados en las asignaturas de Química, Física y Biología. Como primer paso, se investigó el grado de conocimiento sobre astronomía del estudiante. Este estudio inicial mostró niveles de conocimiento muy bajos de los conceptos básicos de esta ciencia, muchos de los cuales deberían haber sido asimilados dentro del plan curricular del curso de Física. Este estudio previo permitió determinar las actividades adecuadas para promover un mayor envolvimiento de los estudiantes

    -Resolution Aerosol Mass Spectrometer (AMS) (DeCarlo et al., 2006). These state-of-the-art techniques have been applied for the first time in the Western Mediterranean region within DAURE. Particular attention was devoted to quantitatively understand the sources and formation mechanisms of secondary inorganic and organic aerosols (SIA and SOA) in the WMB and the effects caused by anthropogenic activities in SOA formation at local and regional level. Here we give an overview of the objective of the DAURE campaign, groups involved and measurements performed. The main results of the DAURE winter and summer campaigns will be presented and discussed. Temporal series and diurnal cycles of the detailed PM speciated data, gas-phase concentrations and meteorological data obtained at both Barcelona and Montseny stations will be presented and interpreted as a function of the different atmospheric scenarios observed during the DAURE campaigns.

    Here are presented preliminary results of the MINHO09 cruise, carried out within the scope of the paleoclimatic research task of the MINHO project (PROYECTO 0234_NATURA_MIÑO_MINHO). Bed features and sediment distribution were mapped in the Minho estuary (Northern Portugal) using a dual frequency sidescan sonar mosaic (EdgeTech 4200-MP), and bottom sediment texture data from 71 sites sampled with a winch operated sediment grab (Van Veen type). The survey was done within 5 days, in low flow energy conditions of summer dry weather and neap tides, close to optimal conditions for correlating the acoustic imagery with the bottom sediment data. A DGPS (Omnistar 8200HP) was used to determine the horizontal position of the acoustic imagery and the sediment sample sites with sub-meter accuracy. Uncorrected water depths were determined with a depth echo-sounder (Odom HYDROTRAC echo sounder), and the water depths referred to the local datum was later determined using data from a tidal gauge (Valeport model 740) deployed specifically for this survey. Overall the sampled sediments were mostly poorly calibrated, with grain sizes ranging from gravel to mud coexisting in the same sample, probably reflecting the great seasonal contrast in flow conditions in the Minho River. The predominantly muddy sediments were observed along the river margins (frequently charged with gas) and, locally, along relatively deeper portions of the channel bed. The bedforms observed in the sidescan sonar data are dominated by 2D and 3D dunes and ripples. There are several locations were the bedforms suddenly change from larger dunes (wave lengths greater than 5m) to smaller ripples (wave lengths smaller than 1m). These changes may be related to the occurrence of supercritical flow conditions (Froude number > 1): hydraulic jumps in places were there is a sudden change in depth without any change in channel width, or chutes and pools in places were there is a sudden change in channel width; future work is

    Servicios Ambientales Culturales Resumen Los deseos, necesidades y valores no materiales de los accionistas influyen frecuentemente sobre el éxito de los proyectos de conservación. Estas consideraciones son difíciles de articular y caracterizar, lo que resulta en entendimiento limitado en el manejo y la política. Concebimos un protocolo de entrevista diseñado para mejorar el entendimiento de los servicios ambientales culturales (SAC). El protocolo inicia con la discusión de actividades relacionadas con ecosistemas (p. ej.: recreación, cacería) y manejo; después señala a los SAC, dando pie a los valores que encierran conceptos identificados en la Evaluación Ambiental del Milenio (2005) y explorado en otras investigaciones sobre SAC. Hicimos pruebas piloto del protocolo en Hawái y Columbia Británica. En cada localidad entrevistamos a 30 individuos de diversos entornos. Analizamos los resultados de las dos localidades para determinar la efectividad del protocolo de entrevista en la obtención de valores no materiales. Los componentes cualitativos y espaciales del protocolo nos ayudaron a caracterizar los valores culturales, sociales y éticos asociados con el ecosistema de múltiples maneras. Los mapas y las preguntas de situación, o de tipo viñeta, ayudaron a los encuestados a articular valores difíciles de discutir. Las preguntas abiertas permitieron a los encuestados expresar una diversidad de valores ambientales y demostraron ser suficientemente flexibles para que los encuestados comunicaran valores que el protocolo no buscaba explícitamente. Finalmente, los resultados sugieren que ciertos valores, aquellos mencionados frecuentemente en la entrevista, son particularmente prominentes para poblaciones particulares. El protocolo puede proporcionar datos eficientes, contextuales y basados en lugar sobre la importancia de atributos ambientales particulares para el bienestar humano. Los datos cualitativos son complementarios para las evaluaciones cuantitativas y

Whereas around 15% of enrolled women had evidence of COPD with FEV1/FVC < 70% after bronchodilators, only 4.8% were physician-diagnosed. Asthma did not appear to be a significant spirometric finding in these female subjects, although around 11% had physician-diagnosed asthma. One limitation is FEV1/FVC < 70% could have also resulted from uncontrolled asthma. The same limitation has been reported by the Proyecto Latinoamericano de Investigacion en Obstruccion Pulmonar (PLATINO) study. Contrary to popular belief in developing countries, women exposed to tobacco smoke, whether active or passive, and whether by cigarettes or narghiles, like men are at increased risk for the development of COPD, although cultural habits and taboos may decrease the risk of active smoking in some women. These findings will be considered for country and region strategy for noncommunicable diseases, to overcome underdiagnosis of CRD in women, fight widespread female cigarette and narghile smoking, and promote behavioral research in this field.

    the evidences point to the occurrence of concentrated seismic activity during the OIS 5 (Last Interglaciar) interfering early human activity in the zone. Presently, the Tagus Basin is subject to moderate seismic activity with strongest seismic events not exceeding intensity VI MSK (1954 AD), but most of them related to the Jarama, Tajuña and Tagus river valleys, which are bounded by large linear escarpments carved in Miocene gypsums. These escarpments display a wide variety of brittle and ductile deformations, as well as clear geomorphological indicators of late Quaternary tectonic activity. Considering the recent ESI-2007 Scale, the reported structures indicate the occurrence of larger paleoearthquakes during the Middle-Late Pleistocene of at least local intensity VIII. This study has been supported by the DGPH de la Comunidad de Madrid, AUDEMA S.A. (Proyecto Arriaga-2009). This is a contribution of GQM-AEQUA.

    There are close to 1 million people in the world who are alive simply because they have access to one form or another of renal replacement therapy (RRT). Ninety percent live in high-income countries. Little is known of prevalence and incidence of chronic kidney disease and of end-stage renal disease (ESRD) in middle-income and low-income countries, where the use of RRT is scarce or nonexistent. However, no intervention is undertaken, these people will experience progression to ESRD and death from uremia, because RRT is out of reach for them. These are the individuals for whom efforts should be focused to prevent or delay progression toward ESRD. In 1992, the Mario Negri Institute for Pharmacological Research in Bergamo, Italy, with the cooperation of the young doctors of the Ospedale Giovanni XXIII in La Paz (Bolivia), activated a specific project titled "El Proyecto de Enfermedades Renales en Bolivia" (The Project for Renal Diseases in Bolivia). The project sought to demonstrate that in emerging countries the best strategies against renal disease are prevention and early detection. After proper training of local personnel at the Clinical Research Center "Aldo e Cele Dacco" of the Mario Negri Institute in Bergamo, Italy, an educational campaign titled "First Clinical and Epidemiological Program of Renal Diseases"-under the auspices of the Renal Sister Center Program of the International Society of Nephrology-was conducted in 3 selected areas of Bolivia, including tropical, valley, and plains areas. The goal was to define the frequency of asymptomatic renal disease in these areas by screening a large population of patients at relatively low costs. The screening was formally performed at first-level health centers (Unidad de Salud). Participants were instructed to void a clean urine specimen, and a dipstick test was performed. Patients with positive urinalysis were enrolled in a follow-up program with subsequent laboratory and clinical checks. The study was conducted

    The Zamora Batholith is an intrusive complex that is located in the extreme south-east of Ecuador. It has dimensions of 200 x 50 km approximately. It is mainly located in the Zamora Chinchipe province from which it takes its name. This study consisted in the petrographic and geochemical characterization of the Zamora Batholith in the area covered by 1: 50,000 geological maps of Centro Shaime, Guayzimi, Paquisha, Los Encuentros and El Pangui. Fieldwork was done by the "Proyecto Mapeo Geológico escala 1:50.000 (zonas prospectivas mineras)" of the Instituto Nacional de Investigación Geológico, Minero, Metalúrgico of Ecuador. This research was performed with 59 thin sections and 10 whole - rock chemical analysis done in the C.I.C of the Granada University. The Zamora Batholith intrudes Triassic to Jurassic volcanic rocks. It is overlaid by sandstones of the Hollin Formation of the Upper Aptian age and shale and limestone from the Napo Formation. Post-cretaceous deposits of ash and lava flows of andesitic to rhyolitic compositions cover the batholith. The petrography of the Zamora Batholith ranges from tonalite to monzogranite with the same qualitative mineralogy. The rocks are composed by different proportions of plagioclase, amphibole, feldspar K, quartz, biotite, opaque, pyroxene and epidote, as accessory minerals has zircon, sphene and apatite. To the south of the Conguime and Guayzimi towns, the dominant petrography is medium to coarse grained amphibole granodiorite with tonalitic and monzogranitic subordinates. To the north monzogranites are dominant rocks and subordinate granodiorites. To the East of Santa Elena the sienogranites are associated with El Hito porphyritic granite that intrudes to Zamora Batholith. Frequently the batholith has propylitic alteration; which produces a primary association of chlorite, epidote, calcite and pyrite. The granitoids have dioritic to granitic compositions (60.09 to 73.6 wt.% SiO2) and are I - type, medium to high-K calc

    The pattern of gas-exchange (CO{sub 2} emission) was investigated for developing Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann) pupae incubated at different temperatures. This study was undertaken to explore the usefulness of gas-exchange systems in the determination of physiological age in developing pupae that are mass produced for sterile insect technique projects. The rate of CO{sub 2} emission was measured in a closed flow-through system connected to commercial infrared gas analysis equipment. Metabolic activity (rate of CO{sub 2} emission) was related to pupal eye-color, which is the current technique used to determine physiological age. Eye-color was characterized digitally with 3 variables (Hue, Saturation and Intensity), and color separated by discriminant analysis. The rate of CO{sub 2} emission throughout pupal development followed a U-shape, with high levels of emission during pupariation, pupal transformation and final pharate adult stages. Temperature affected the development time of pupae, but not the basic CO{sub 2} emission patterns during development. In all temperatures, rates of CO{sub 2} emission 1 and 2 d before adult emergence were very similar. After mid larval-adult transition (e.g., phanerocephalic pupa), digital eye-color was significantly correlated with CO{sub 2} emission. Results support the suggestion that gas-exchange should be explored further as a system to determine pupal physiological age in mass production of fruit flies.

    Irradiation of pupae in sterile insect technique (SIT) projects is usually undertaken in hypoxic atmospheres, which have been shown to lessen the deleterious effects of irradiation on the quality of adult sterile flies. Although this is the accepted technology in most mass-rearing and sterilization facilities, to date no information has been generated on the actual levels of oxygen (O{sub 2}) in pupae-packing containers during irradiation. The present study utilized recently-developed technology to investigate the O{sub 2} level inside bags in which pupae of Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann) are packed prior to irradiation, the ability of pupae to create hypoxic environments in these bags, and the effect of O{sub 2} atmospheres on the quality of irradiated males. Pupae, 1 d before adult emergence, were shown to deplete the O{sub 2} level in sealed bags in approximately 1 h. The rate of O{sub 2} consumption was dependent upon pupal age and incubation temperature. Incubation temperature did not significantly affect the quality of pupae or mating capacity of resultant adult males if pupae were irradiated under maximal hypoxic conditions inside packing bags. In contrast, mating competitiveness drastically decreased when pupae were irradiated under ambient O{sub 2} conditions, with the packing bag open. There was no difference in the mating capacity of males when pupae were irradiated in sealed bags under either 10% or 2% O{sub 2} levels, or under maximal hypoxia. Normal doses of fluorescent dye, applied to pupae to mark sterile flies, did not affect the ability of pupae to create hypoxic conditions inside packing bags, nor the quality control parameters of either pupae or adults. Current practices in mass-rearing facilities are discussed in the light of these results.

Results show that Spanish public discourse on fracking technology includes the costs-benefits analysis to communicate how natural resources from local communities may be affected by these facilities due to environmental, health and economic consequences. Furthermore, this technology is represented as a solution to the "demand of energy" according to the optimistic discourse while, from a pessimistic view, fracking is often framed as a source "environmental problems" and even natural disasters as possible earthquakes. In this latter case, this negative representation could have been influenced by the closure of a macro project to store injected natural gas in the Mediterranean Sea using the old facilities of an oil exploitation in Amposta (Proyecto Cástor). The closure of this project was due to the occurrence of earthquakes whose intensity was higher than the originally expected by the experts in the assessment stage of the project.

    esteriles de moscas para el proyecto de la tecnica del insecto esteril (TIE) en huertos de frutos y vinas comerciales en la provincia del Cabo Occidental del Sudafrica. El procedimiento de criar en masa fue en su mayor parte basado en los sistemas desarrollados por el Laboratorio de Agricultura y Biotecnologia de la FAO/IAEA, Seibersdorf, Austria. Un numero de razas que separara los sexos geneticamente fueron utilizadas para producir solo machos para la liberacion. La congestionada condicion inicial para criar las moscas y su manejo de calidad fueron aliviadas en 2001 con la construccion de un nuevo cuarto de cria para adultos y un laboratorio de control de calidad. En 2002, un Sistema de Manejo de Calidad comprensivo fue implementado, y en 2003 una raza mejorada que separa los sexos geneticamente, VIENNA 8, fue proveido por el Laboratorio de la FAO/IAEA en Seibersdorf. En la mayor parte de los primeros 3 anos la facilidad no pudo suplir el numero requerido de machos esteriles de la mosca mediterranea de la fruta para el programa de TIE sin la necesidad para importar machos esteriles de otra facilidad. Desde medio del ano de 2002, despues que el sistema de manejo de calidad fue implementado, la produccion y la calidad mejoraron pero aun quedaron por debajo del nivel optimo. Despues de la introduccion de la raza VIENNA 8 que separa los sexos geneticamente, y junto con el equipo mejorado de control de clima, la estabilidad y los parametros de seguridad de calidad mejoraron substancialmente. Los factores criticos que influyeron en la produccion y la calidad fueron la infraestructura inadecuada para criar las moscas, problemas con la calidad de la dieta para las larvas y la ausencia inicial de un sistema de manejo de calidad. Los resultados muestran claramente la importancia de un manejo efectivo de la calidad, el valor de una raza productiva que separa los sexos geneticamente y la necesidad de contar con una base solida de financimiento para la infraestructura de una cria en

    Research developed with 95 students of the 6th year of elementary education in a public school of Uberlândia, Minas Gerais. It was a continuous work from February to December 2013, which led the students to participate in activities of observation of the environment, specifically the sky, analyzing the changes occurred. We focused on the study of variations in temperature, rainfall, day length, variations in the size of the shadows and changes in the aspect of the Moon. Our focus of analysis targeted the discussion of the knowledge that these students had about the topics indicated and as they entered the stage during the implementation of the proposal. The results showed a limited perception that students have of their environment, however, lately expanded due to the undertaken activities, especially in relation to the Moon. Working with systematic measure procedures reveals the careful handling of data so that they become understandable to students, and working with the shadows points towards the students first understand how shadows are formed, and then apply this knowledge to Astronomy. Finally, we conclude that the lived process consisted of an initial step of a work that should be encouraged for the subsequent years of training of these students.

    The use of observational records in the design of teaching sequences in Astrophysics in High Schools is quite uncommon. It is also uncommon the thematic approach within the context provided by Nature of Science. Besides these shortcomings, we should also consider the lack of proposals to use the computer as a laboratory from which nature is studied. These aspects expose the existence of a disconnection between school science and scientist's science, establishing the need for simple educational projects that promote interdisciplinary dialogue between the two fields of knowledge. Based on these assumptions, this paper presents the school reformulation of the redshift-distance problem as addressed by Hubble in his diagram, and explores the main educational dimensions emerging from it. The proposal is directed not only for senior students of high school and/or early 1st year students at University level, but also for students and teachers from teacher training colleges. Practical evidence shows that this proposal is viable, mobilizes interests about issues of Astrophysics and promotes a ludic and cooperative character among students. La utilización de registros observacionales en el diseño de secuencias didácticas en Astrofísica Escolar no es algo usual en el ámbito de la escuela media. Tampoco lo es el abordaje de temáticas desde el contexto que provee Naturaleza de la Ciencia. A estas carencias se le suma la falta de propuestas que hagan intervenir a la computadora como un laboratorio desde el cual se interpela a la naturaleza. Los aspectos mencionados exponen la existencia de un desajuste entre ciencia escolar y ciencia experta estableciendo la necesidad de elaborar proyectos educativos sencillos que promuevan el diálogo interdisciplinar entre ambos campos del conocimiento. Partiendo de estos presupuestos, en este trabajo se presenta la reformulación escolar del problema abordado por Hubble -que diera lugar al diagrama que lleva su nombre- y se exploran las

La parametrización de G se optimiza usando datos de flujo de energía obtenido durante las campañas del proyecto AMMA, y muestra buenos resultados y una mejora de las estimaciones del flujo de calor sensible (H) y de ET cuando se utiliza conjuntamente con el método del triángulo (Jiang & Islam, 2001). En una segunda parte (Capítulo 5), el método del triángulo se compara con valores de ET estimado por un modelo de superficie terrestre (JULES). Se intenta calibrar JULES usando el método del triángulo mediante simulaciones de Monte Carlo, pero los dos métodos muestran resultados muy diferentes, indicando que se necesita tareas de comparación profundizadas para poder evaluar la eficacia de estos modelos (de superficie terrestre y basados en la teledetección) para estimar los flujos de energía a la superficie. El capítulo 6 presenta un conjunto de ejemplos de aplicaciones operacionales para estimar los flujos de superficie usando datos de teledetección. El primer ejemplo consiste en el estudio de la evolución temporal de mapas de ET en África occidental bajo la influencia del monzón africano. En el segundo ejemplo, se aplica la nueva parametrización de G descrita en el capítulo 4 para calcular y analizar la evolución a largo plazo (2000-2009) de los componentes del balance de energía a la superficie, G, H y ET, en diferentes puntos de la cuenca del río Segura (Sureste español) utilizando datos del sensor MODIS-Terra (temperatura superficial y NDVI).

C'est ainsi que la loi laisse entendre que l'infiltration à partir des lits de rivières le long du champ captant central favorise la recharge de cette zone. En réalité, les différences de perméabilité entre les alluvions du lit et les dépôts sous-jacents remplissant le bassin peuvent provoquer un écoulement sous-jacent. En outre, même si une recharge par l'eau de la rivière Colorado se produit dans cette zone, la nappe sera progressivement salifiée. Les restrictions imposées par la loi quant à l'utilisation de l'eau de la station centrale d'Arizona affectent les quatre outils réglementaires du Code des eaux souterraines de l'Arizona de 1980, en ce qu'ils concernent la zone de gestion active de Tucson: (a) l'augmentation de l'approvisionnement (b) les conditions requises pour les prélèvements d'eau souterraine et les autorisations; (c) les conditions requises pour le plan de gestion, en particulier la pérennité du concessionnaire et les résultats en matière de qualité de l'eau et (d) la condition que tous les nouveaux districts aient recours à des ressources en eau renouvelables à la place de l'eau souterraine.

Le modèle résultant a servi à tester sept scénarios de gestion pour une période de programmation de 21 ans, afin de déterminer les débits de prélèvement sûr et durable dans le système aquifère et d'étudier les impacts potentiels de quatre réservoirs d'eau de surface en projet sur les eaux souterraines du bassin. Les résultats montrent que la poursuite des prélèvements au débit actuel excède aussi bien le débit d'exploitation de sécurité que celui durable pour le système aquifère. Par conséquent, les besoins croissants d'eau pour l'irrigation doivent être satisfaits par la construction des réservoirs projetés et par la mise en place de politiques et de plans de gestion de l'eau efficace. Este estudio presenta el establecimiento de políticas sustentables de desarrollo y gestión en el sistema acuífero de la cuenca del río Küçük Menderes, al Oeste de Turquía, para lo que se ha utilizado datos geológicos, hidrogeológicos y geofísicos de forma conjunta de cara a definir diversas unidades hidrogeológicas y su geometría. La distribución de los parámetros hidráulicos y de la recarga ha sido estimada mediante métodos geoestadísticos y simulaciones hidrológicas, respectivamente. Se ha empleado un modelo de las aguas subterráneas en diferencias finitas para representar el flujo no confinado en el sistema acuífero, el cual se ha calibrado bajo condiciones estacionarias y transitorias. El modelo resultante ha sido usado para contrastar siete escenarios de gestión durante un período de planificación de 21 años con el fin de determinar el punto de explotación segura y sustentable del sistema acuífero, así como para investigar los impactos potenciales sobre los recursos subterráneos de los cuatro embalses superficiales que se hallan en proyecto. Los resultados demuestran que el mantenimiento de las tasas actuales de extracción del acuífero supera tanto el régimen de bombeo seguro como el sustentable del

    Many misconceptions are recognized among the various groups of students, especially in the elementary school. Among them, the apparent motion of the Sun, in spite of its daily occurrence, is subject to varied interpretations. Thus, the observation and recording of the motion of the stars in the celestial vault is a necessary task for astronomy education. The work presented here proposes the presentation of the results of observations of the apparent movement of the sun by marking the shadow of a vertical gnomon by the students in a class of sixth graders of elementary rural school of Paraná. The project itself was conducted in four stages, on dates near the March equinox, the June solstice, the September equinox and the December solstice. In addition, lectures were developed in the classroom. Such methods sought to build concepts around the apparent movement of the Sun and the alternation of the seasons. Given the results of the activities, an evaluation was applied and the data demonstrated a desired student learning such as: the recognition of the cardinal points, the description of the apparent solar motion and the occurrence of the seasons and their alternation from astronomical observations at naked eye. Muchos conceptos aternativos son conocidos entre los distintos grupos de alumnos, sobre todo en la educación básica. Entre ellos, el movimiento aparente del Sol, por más cotidiano que sea, se presta a interpretaciones variadas. Por lo tanto, observar y registrar el movimiento de las estrellas en la bóveda celeste se torna una tarea necesaria para la educación en astronomía. El trabajo que aquí se presenta propone la presentación de los resultados de la observación del movimiento aparente del sol a través de la marcación de la sombra del gnomon vertical a cargo de los estudiantes en una división de sexto grado de de la escuela primaria rural de Paraná. El proyecto en sí se llevó a cabo en cuatro etapas, en fechas cercanas al equinoccio de marzo

    This paper reports on the characterization of hydraulic properties of regional rock aquifers carried out within a groundwater resources assessment project in the St. Lawrence Lowlands of south-western Quebec. To understand the aquifer behavior at both the fracture level and at field scale, hydraulic investigations were carried out using various aquifer tests. The groundwater flow at the local scale is controlled mostly by the fracture system. Results of the constant-head injection tests show a weak decreasing trend of hydraulic conductivity with depth indicating that a major part of the groundwater flow occurs in the first meters of the rock sequence. At the regional scale, the equivalent porous media approach is applicable. The hydraulic conductivity measurements were correlated to the scale of the aquifer tests expressed with the investigated aquifer volume. A simple interpolation procedure for the hydraulic conductivity field was developed based on the distance between field measurements and the tested aquifer volumes. The regional distribution of the hydraulic conductivity for the major fractured aquifer units indicates that dolostone is the most permeable whereas sandstone and crystalline rocks are the least permeable units. Este artículo trata de la caracterización de las propiedades hidráulicas en acuíferos regionales rocosos, la cual se llevó a cabo dentro del proyecto de evaluación de los recursos de agua subterránea en St. Lawrence Lowlands al suroeste de Quebec. Para entender el comportamiento del acuífero tanto a nivel de fractura como a escala del campo, se ejecutaron investigaciones hidráulicas usando varias pruebas de acuífero. El flujo del agua subterránea a escala local está controlado principalmente por el sistema de fracturas. Los resultados de las pruebas de inyección con cabeza constante muestran una tendencia decreciente débil de la conductividad hidráulica con la profundidad, indicando que la mayor parte del flujo de agua

    behandelten Fälle legt nahe, dass die Mehrzahl der Therapeuten keine grundlegende Kompetenz in zeitlich limitierter dynamischer Psychotherapie erworben hatte. Cette éude explore les effets sur les résultats thérapeutiques de la formation des thérapeutes dans une thérapie brève, manualissée. Dans le cadre du projet Vanderbilt II, chacun des 16 thérapeutes (8 psychiatrs et 8 psychologues cliniciens) a traité deux patients adultes modérément perturbés, chacun par sa méthode habituelle de thérapie brève; ensuite ils ont reçu une formation d'une année dans une méthode manualisée de thérapie brève, la Psychothérapie Dynamique Limitée dans le Temps (TLDP); pour finir, ils ont appliqué la TLDP à de meilleurs résultats en général, et qu'une amélioration comparativement plus importante sera observée chez des patients habituellement considérés comme moins adaptés à une thérapie dynamique brè. Les résultats obtenus à la terminaison n'ont pu confirmer aucune de ces hypothèses. Des mesures de la dépendance interpersonnelle une année après étaient consistantes avec la première hypothèse, mais les données catamnestiques étaient inconsistantes avec la deuxième. Une revue systématique des 32 cas après formation a suggéré que la majorité des thérapeutes n'avait pas acquis une compétence de base en TLDP. Este estudio exploró la efectividad del entrenamiento de terapeutas en una terapia breve manualizada. Como parte del proyecto Vanderbilt II, dieciséis terapeutas (ocho psiquiatras y ocho psicólogos clínicos) trataron dos pacientes adultos mooderadamente perturbados con sus métodos habituales de tratamiento a corto plazo.

    ée. L'objectif de cet article est de présenter et de discuter les résultats cliniques de sept années de travail impliquant 2116 femmes traitées dans trois hôpitaux à travers le pays. Méthodes Il s'agit d'une étude de cohorte rétrospective utilisant des données extraites des dossiers médicaux de réparations de fistules menées de 2007 à 2013. Les données de l’étude ont été analysées au cours de la période allant d'avril à août 2014. Résultats La majorité des 2116 femmes qui ont subi une réparation chirurgicale avaient une fistule vésico vaginale (n = 2 045, 97%) et 3% avaient une fistule recto vaginale ou une combinaison des deux. Au total, 1748 (83%) femmes ont eu leur fistule refermée et sont devenues continentes d'urine immédiatement après la chirurgie. À la sortie, 1795 femmes (85%) avaient une fistule fermée et 1680 (79%) étaient sèches, c'est à dire qu'elles n'avaient plus de fuite d'urine et/ou de matières fécales. 115 (5%) femmes avaient toujours une incontinence résiduelle malgré la fermeture de la fistule. Le suivi à trois mois a été complété par 1663 (79%) femmes dont 1405 (84,5%) ont eu leur fistule fermée et 80% étaient continentes. 21% ont été perdues au suivi. Conclusion La réparation programmatique de routine de la fistule obstétricale dans les régions à faibles ressources peut donner de bons résultats. Toutefois, davantage d'efforts sont nécessaires pour remédier à la perte au suivi, maintenir les résultats et prévenir l'apparition et/ou la réapparition de fistules. Objetivos La fístula genital femenina continúa siendo una preocupación de salud pública en países en vías de desarrollo.

    ha a été programmée, en partie dans un bassin évaporitique fermé où existent des lacs de playa. Le projet a fait émergé des préoccupations environnementales. L'évaluation des impacts hydrologiques de l'irrigation implique de quantifier correctement l'hydrogéologie de cette région. A partir des informations disponibles, un modèle hydrogéologique conceptuel a étéétabli il identifie deux aquifères principaux interconnectés par drainance au travers d'un imperméable. Un modèle numérique, établi sur la base de ce modèle conceptuel, a été calibré en conditions de régime permanent, en utilisant la méthode d'estimation automatique du maximum de vraisemblance des paramètres (Carrera and Neuman, 1986a). Le modèle calibré reproduit correctement la piézométrie mesurée et est en accord avec les informations concernant l'écoulement des nappes. La résolution du problème inverse a fourni des estimations acceptables des paramètres. On en a conclu que l'anisotropie joue un rôle essentiel dans certaines parties de l'aquifère inférieur. La moyenne géométrique de la conductivité hydraulique est d'environ deux ordres de grandeur plus élevée que la conductivité hydraulique moyenne obtenue par des essais de terrain à l'échelle locale. Cet effet d'échelle sur la conductivité hydraulique est conforme aux résultats obtenus par Neuman (1994) et Sánchez-Vila et al. (1996). Resumen La hidrogeología de zonas endorreicas en zonas evaporíticas ha recibido muy poca atención en el pasado debido fundamentalmente a que en estas zonas las aguas subterráneas tienen una elevada salinidad debido a la alta solubilidad de sus materiales. El interés por la hidrogeología de la zona de Los Monegros en el noreste de España surgió a raiz de la aprobación en 1986 del proyecto de Los Monegros II en la zona central del valle del Ebro que contempla la puesta en regadío de 60,000 ha, algunas de las cuales se encuentran situadas en la zona endorreica de Los

    dans l'aquifère captif profond, puisque la recharge à partir des aquifères superficiels au travers de la couche de limon est la seule alimentation de l'aquifère profond. Une analyse des distributions spatiales de l'abaissement du niveau piézométrique et des tassements du sol montre que la région soumise à l'abaissement maximal de piézométrie n'est pas nécessairement celle des tassements maximaux du sol liés à la présence de la couche de limon non consolidé. Une simple révision des débits de pompage basée sur la distribution spatiale de la couche de limon épaisse peut réduire significativement les tassements du sol. Resumen. La ciudad de Suzhou, situada en el tramo inferior del Río Yangtze, al sudeste de la provincia de Jiangsu, es una de las pocas ciudades chinas que padece problemas serios de subsidencia. Esto ha motivado la realización de un proyecto de investigación en la zona. Estudios geológicos e hidrogeológicos apuntan a un modelo de acuífero multicapa, con tres niveles distintos de lodos blandos de orígenes marino y lacustre. Examinando los registros históricos de extracciones de agua subterránea, así como de nivel piezométrico y de subsidencia, se observa que ésta se halla asociada al bombeo cada vez mayor del acuífero confinado profundo. La hipótesis es que las capas de lodos blandos se van consolidando, si bien la que más contribuye a ello es la tercera, potente y próxima al acuífero más explotado. Se ha realizado un modelo numérico tridimensional en diferencias finitas que representa el sistema acuífero multicapa, con lo que se puede estudiar el efecto de la extracción de agua subterránea en la subsidencia. Calibrando el modelo con niveles piezométricos medidos y con datos de subsidencia, se ha podido estimar los parámetros del acuífero. Los resultados del modelo ajustan de forma razonable con los datos medidos, por lo que el modelo numérico es capaz de reproducir los procesos dinámicos de flujo de aguas

    subsurface devant être évaluée. Ceci permet de prendre des décisions plus pertinentes et pratiques. Dans cet article, certaines perspectives sur le développement d'approches «upscaling» (changement d' échelle) sont présentées, mettant en lumière des concepts mutli-échelles récents, en mettant de côté le problème du milieu fracturé. L'upscalling peut être utilisé comme un cadre utile pour gérer simultanément les problèmes d'échelle de travail, les approches stochastiques et les problèmes inverses. Les applications effectives et potentielles de l'upscalling sont mis en lumière, dans l'élaboration de modèles de subsurface contraints aux données observées, et la gestion des incertitudes et des études de sensibilité dans un cadre multi-échelle global. L'upscaling peut, en particulier, aider à trouver les paramètres qui contrôlent le comportement global de l'écoulement. Finalement, les approches par upscaling des équations non-linéaires de transport apparaissent comme une nouvelle frontière dans cette aire de recherche. Las formaciones geológicas son entidades complejas que resultan de procesos geológicos, mecánicos, y físico-químicos que ocurren en un rango muy amplio de escalas espaciales y escalas temporales. Los procesos de transporte que varían de la escala molecular a varios cientos de kilómetros pueden influenciar el comportamiento global del flujo de fluido en estas formaciones. Las heterogeneidades que cubren un rango amplio de escalas espaciales juegan un papel esencial para canalizar flujos de fluidos, especialmente cuando están acoplados con no linealidades inherentes a procesos de transporte en medios porosos. Estos asuntos tienen importancia práctica considerable en la gestión de aguas subterráneas, y en la industria petrolera, particularmente en la solución de problemas nuevos ocasionados por proyectos relacionados con el entrampamiento de CO2 en el subsuelo. Para gestionar esta complejidad uno tiene que priorizar

    pour assister les décideurs, les propriétaires de puits et les autres acteurs pour atteindre progressivement un régime de prélèvement durable. Les aspects sociaux et économiques de chaque option et de chaque scénario ont été analysés et présentés aux acteurs, en même temps qu'un résumé des ramifications légales, institutionnelles et environnementales. En combinant une analyse scientifique à une approche participative du bassin d'Amman Zarqa, la gestion des eaux souterraines a été imaginée comme un prototype pouvant être utilisé pour la gestion d'autres bassins aquifères de Jordanie. Il peut également être utile à d'autres régions du monde qui sont concernées par des problèmes similaires de surexploitation des eaux souterraines. La sobreexplotación de las aguas subterráneas ha ido en aumento en Jordania, donde las demandas en competición han crecido frente a una escasez perenne de agua, situación que ha sido agravada por el estado de sequía de la última década. Este artículo presenta los hallazgos de un proyecto en el que se han desarrollado opciones de gestión para hacer frente a la sobreexplotación en uno de los principales sistemas acuíferos de Jordania: la cuenca de Ammán-Zarga. Se ha elaborado opciones para afrontar la situación mediante un enfoque participativo que incluye a personal del gobierno y a diversos grupos de interés de los sectores público y privado. En particular, se ha intentado involucrar a los regantes que se sirven de aguas subterráneas, quienes tienen más probabilidad de ser directamente afectados por los cambios requeridos para devolver el sistema a un balance equilibrado. A partir de la información obtenida en rápidas campañas de valoración, así como de encuentros con la comunidad y entrevistas con los expertos técnicos del gobierno, se ha identificado un amplio conjunto de opciones para su evaluación. Basándose en un análisis integrado de los aspectos hidrogeológicos, sociales y econ
