Aspectos jurídico administrativos de los desastres naturales y del reasentamiento poblaciónal y su planteamiento como política pública

Esta investigación tiene el propósito de analizar los aspectos jurídicos de los desastres naturales y del reasentamiento poblacional. Se presentan las distintas tipologías del reasentamiento poblacional desde la óptica estatal para señalar su importancia en las actividades de las autoridades administrativas. En el trabajo se muestra la vulnerabilidad del Estado Colombiano frente a la ocurrencia de desastres naturales, por la falta de planeación efectiva y la poca importancia de la reducción del riesgo en la agenda pública. Desarrolla igualmente, el fundamento de la responsabilidad de la administración frente a desastres de la naturaleza y su papel ante la protección de los derechos humanos. Además, desarrolla el reasentamiento poblacional como mecanismo de atención y prevención de desastres naturales, y la normatividad nacional y de la región andina en la cual está contenido. Establece estrategias de acción estatal para la atención práctica de los desastres naturales, el planteamiento del reasentamiento poblacional como política pública y herramientas de protección de la población vulnerable. Por último, plantea la importancia de la reducción de los riesgos de la población ante desastres de la naturaleza y la necesidad de protección del Estado de las poblaciones vulnerables para mejorar sus condiciones de vida.

Mental Health Promotion: A Framework for Action and Education

This document is a revision of some major concepts of health promotion in order to provide a framework for the action of those who work in mental health. Since the Ottawa charter, new references on health can contribute significantly for the education and action of the mental health practitioner. In order to promote and enhance better and healthier ways if living as well as better life conditions. Mental health is considered as a tool for the understanding and construction of the sense of well being and well living. In our country our professional training programs have understood the importance of educating in a more integrated and holistic way in the search for creative approaches for problems we face in our every day life, based on the hope that a better country with more equity and justice, as well as better and healthier conditions can be more than just a dream.

Presente y futuro de las metrópolis de América Latina

En América Latina se aplicó salvajemente el neoliberalismo, con resultados lamentables: no logró una acumulación capitalista sostenida, y se deterioraron las condiciones de vida de la población. Las ciudades neoliberales son más contradictorias que sus predecesoras capitalistas: mantienen sus vicios y perdieron sus pocas virtudes. En el siglo XXI, concluirá la urbanización mundial. Latinoamérica será una de las regiones más urbanizadas. Sus metrópolis y ciudades-región, con su gigantismo, desorden, dispersión, privatización, fragmentación, informalización, empobrecimiento, exclusión, confl ictividad, violencia y contaminación iniciaron este siglo en crisis estructural y social; su futuro aparece como la disyuntiva entre la profundización de su crisis, o el cambio de organización económica, social y territorial, para revertir sus componentes básicos. 

Relación de las condiciones de salud y trabajo con la calidad de vida laboral, en trabajadores de dos instituciones hospitalarias de Boyacá, Colombia

Introducción: La Calidad de vida en el trabajo tiene componentes objetivos y subjetivos, es la manera como se vive la cotidianidad en el ambiente laboral. Involucra condiciones de trabajo, relaciones sociales, percepciones de satisfacción o insatisfacción derivadas de la conjunción de factores en el sentido de sentirse realizado con sus propias expectativas y proyectos (1). La calidad de vida laboral puede estar directamente relacionada con las condiciones de trabajo en las que se desempeñan los trabajadores. El personal de la salud representa entre el 6 al 7% de la población económicamente activa en la Región de las Américas (2), el abordaje de su problemática debe hacerse desde la protección social en salud,enfocando acciones conducentes al mejoramiento integral de las condiciones de vida de la sociedad en general, a través de la Gestión del Recurso Humano. Métodos: Estudio transversal en 102 trabajadores que cumplen con criterios de inclusión y exclusión, sobre percepción de calidad de vida laboral y condiciones de salud y trabajo, en dos instituciones prestadoras de Servicios de salud públicas de baja complejidad de los Municipios de Samacá y Ramiriquí en Boyacá en el 2014. Resultados: Del total de los trabajadores encuestados el 64,7 % son asistenciales, el 80,4 son mujeres, el 60 % tienen contrato indirecto. 71 % devenga un salario entre 1 y 2 SMMLV. El 74 % de los trabajadores administrativos laboran ocho (8) horas diarias mañana y tarde, 44 % de los asistenciales laboran ocho (8) horas diarias mañana y tarde y 41 % cumplen jornadas de doce (12) horas diarias inclusive en la noche, en relación a seguridad e higiene hay exposiciones al ruido y a secreciones y desechos de personas o animales. El principal factor de riesgo ergonómico son los movimientos repetidos en administrativos (74,3%) y Asistenciales (76,9 %). El 93,1 % de los trabajadores perciben su salud entre excelente y buena. En cuanto a la Calidad de Vida Laboral sólo el 15% de los trabajadores expresan insatisfacción por la forma de contratación, 56% están entre satisfechos y medianamente satisfechos con el salario recibido, la satisfacción con la oportunidad de aplicar la creatividad e iniciativa en el trabajo es del 90 %, el 33 % de los trabajadores están satisfechos con la capacitación brindada por la institución y sólo el 27 % expresan siempre el respeto a los derechos laborales; Un bajo porcentaje(28 %) de los trabajadores expresan que reciben siempre de parte de usuarios o clientes muestras de reconocimiento por las actividades que realizan; la tenencia de la vivienda se ha dado por el empleo, sin embargo el porcentaje de motivación laboral más alto se da en los asistenciales (81,8 %) que en los administrativos (75,8%). Se encontró escasa asociación estadística entre las variables de Calidad de Vida y las variables de Condiciones de Trabajo y salud Discusión: En esta población la percepción de los trabajadores no refleja una insatisfacción marcada, es entonces ¿el grado de satisfacción de las necesidades humanas un indicador de la mejor o peor calidad de vida laboral? o simplemente la calidad de vida laboral depende del cubrimiento de las expectativas individuales. Este estudio es coincidente con otros en que la proporción mayoritaria de quienes trabajan en salud son mujeres, se deben focalizar acciones desde la perspectiva de género en el sector salud que hagan parte de políticas públicas y de reformas a la salud apuntando a la reducción del impacto de la carga del trabajo en la salud.

Terapias no farmacológicas en el manejo del dolor en neonatos pretérmino. revisión sistemática de la literatura

Antecedentes El dolor en neonatos ha sido un problema poco explorado. Se ha propuesto el uso de las terapias no farmacológicas para su tratamiento, sin embargo existen pocas aproximaciones sistemáticas para la evaluación de su eficacia. Objetivos Determinar la eficacia de las terapias no farmacológicas en el manejo del dolor en neonatos pretérmino a través de una revisión sistemática. Metodología Se realizó una revisión sistemática de la literatura para evaluar la eficacia de las terapias no farmacológicas en el manejo del dolor en el recién nacido petérmino. La búsqueda se realizó a través de las bases de datos Embase, Cochrane, Bireme y Embase. Se identificaron estudios publicados inglés y español. Se realizó un análisis cualitativo y cuantitativo. Resultados Se incluyeron 10 ensayos clínicos. La solución de sacarosa administrada por vía oral mostró reducir la intensidad del dolor en el recién nacido. La intubación y toma de muestras facilitada por el cuidador mostró también reducir la intensidad del dolor. Conclusión Se recomienda la administración solución de sacarosa y acompañamiento del cuidador durante los procedimientos como medidas para reducir el dolor en el recién nacido pretérmino.

Desarrollo, bienestar y comparaciones interpersonales

El presente documento intenta esquematizar los conceptos que han sido estudiados en la teoría económica y que son necesarios para evaluar las condiciones de vida de las personas. Se estudian las distintas posturas que se enmarcan tanto dentro de la vieja como de la nueva economía del bienestar y se concluye que la teoría económica ha llegado a un concepto de bienestar y justicia ampliamente definido que permite evaluar de una manera distinta a los agentes y que también, permite considerar posturas alternativas cuando se habla de condiciones de vida.

Natural resources, redistribution and Human capital formation

How do resource booms affect human capital accumulation? We exploit time and spatial variation generated by the commodity boom across local governments in Peru to measure the effect of natural resources on human capital formation. We explore the effect of both mining production and tax revenues on test scores, finding a substantial and statistically significant effect for the latter. Transfers to local governments from mining tax revenues are linked to an increase in math test scores of around 0.23 standard deviations. We find that the hiring of permanent teachers as well as the increases in parental employment and improvements in health outcomes of adults and children are plausible mechanisms for such large effect on learning. These findings suggest that redistributive policies could facilitate the accumulation of human capital in resource abundant developing countries as a way to avoid the natural resources curse.

Aprender: uma necessidade, um direito e uma possibilidade ao alcance de todos

A transição do 1º para o 2º ciclo implica, em muitos casos, para além de uma mudança nos modelos de organização (espaços, tempos e pessoas…), uma mudança da própria escola. E se uma preparação atempada pode ser facilitadora nesse processo de transição (inter-escolas; escola/família e família/aluno), a verdade é que o novo ciclo implica novos problemas e novos desafios que testam e mobilizam, diariamente, nos alunos em trânsito, a sua capacidade de adaptação a novas situações. Aceitando-se que para um elevado número de crianças, esse período é curto e facilmente ultrapassável, reconhece-se que para outras, a inclusão no novo ciclo exige mais tempo e adaptações específicas, em função das necessidades educativas especiais que manifestam. O trabalho que se apresenta orientado numa perspectiva ecológica e desenvolvido com base numa metodologia de investigação-acção, permitiu-nos um melhor conhecimento do "Pedro" (nome fictício), enquanto pessoa (jovem, aluno, colega, filho, neto, vizinho e amigo), e dos contextos nos quais se movimenta; a identificação das suas potencialidades e necessidades educativas e a definição, implementação e avaliação das respostas educativas que viabilizaram e optimizaram a sua inclusão na escola do 2º ciclo. A intervenção realizada implicou um trabalho de equipa caracterizado pela colaboração e articulação regular, entre os diferentes intervenientes e pela persistência e coerência na acção desenvolvida. Permitiu ainda uma maior consciencialização de que quaisquer que sejam as características que nos tornam singulares, é possível evoluir em relação ao ponto de partida, se nos diferentes contextos de vida de cada pessoa se criarem as condições que viabilizem e estimulem percursos evolutivos. Com o trabalho desenvolvido reforçaram-se relações interpessoais, aprofundou-se a colaboração entre pares; entre a Escola e a Família, entre os Pais e o "Pedro" e desenvolveram-se as aprendizagens dos diferentes intervenientes, conforme testemunha a avaliação realizada.

Holocene settlement shifts and paleoenvironments on the Central Iranian Plateau: investigating linked systems

For thousands of years, humans have inhabited locations that are highly vulnerable to the impacts of climate change, earthquakes, and floods. In order to investigate the extent to which Holocene environmental changes may have impacted on cultural evolution, we present new geologic, geomorphic, and chronologic data from the Qazvin Plain in northwest Iran that provides a backdrop of natural environmental changes for the simultaneous cultural dynamics observed on the Central Iranian Plateau. Well-resolved archaeological data from the neighbouring settlements of Zagheh (7170—6300 yr BP), Ghabristan (6215—4950 yr BP) and Sagzabad (4050—2350 yr BP) indicate that Holocene occupation of the Hajiarab alluvial fan was interrupted by a 900 year settlement hiatus. Multiproxy climate data from nearby lakes in northwest Iran suggest a transition from arid early-Holocene conditions to more humid middle-Holocene conditions from c. 7550 to 6750 yr BP, coinciding with the settlement of Zagheh, and a peak in aridity at c. 4550 yr BP during the settlement hiatus. Palaeoseismic investigations indicate that large active fault systems in close proximity to the tell sites incurred a series of large (MW ~7.1) earthquakes with return periods of ~500—1000 years during human occupation of the tells. Mapping and optically stimulated luminescence (OSL) chronology of the alluvial sequences reveals changes in depositional style from coarse-grained unconfined sheet flow deposits to proximal channel flow and distally prograding alluvial deposits sometime after c. 8830 yr BP, possibly reflecting an increase in moisture following the early-Holocene arid phase. The coincidence of major climate changes, earthquake activity, and varying sedimentation styles with changing patterns of human occupation on the Hajiarab fan indicate links between environmental and anthropogenic systems. However, temporal coincidence does not necessitate a fundamental causative dependency.

Therapeutic modulation of microbiota-host metabolic interactions

The complex metabolic relationships between the host and its microbiota change throughout life and vary extensively between individuals, affecting disease risk factors and therapeutic responses through drug metabolism. Elucidating the biochemical mechanisms underlying this human supraorganism symbiosis is yielding new therapeutic insights to improve human health, treat disease, and potentially modify human disease risk factors. Therapeutic options include targeting drugs to microbial genes or co-regulated host pathways and modifying the gut microbiota through diet, probiotic and prebiotic interventions, bariatric surgery, fecal transplants, or ecological engineering. The age-associated co-development of the host and its microbiota provides a series of windows for therapeutic intervention from early life through old age

The short- and long-term fitness consequences of natal dispersal in a wild bird population

Dispersal is a key process in population and evolutionary ecology. Individual decisions are affected by fitness consequences of dispersal, but these are difficult to measure in wild populations. A long-term dataset on a geographically closed bird population, the Mauritius kestrel, offers a rare opportunity to explore fitness consequences. Females dispersed further when the availability of local breeding sites was limited, whereas male dispersal correlated with phenotypic traits. Female but not male fitness was lower when they dispersed longer distances compared to settling close to home. These results suggest a cost of dispersal in females. We found evidence of both short- and long-term fitness consequences of natal dispersal in females, including reduced fecundity in early life and more rapid aging in later life. Taken together, our results indicate that dispersal in early life might shape life history strategies in wild populations.

Environmentally-acquired bacteria influence microbial diversity and natural innate immune responses at gut surfaces

Background: Early microbial colonization of the gut reduces the incidence of infectious, inflammatory and autoimmune diseases. Recent population studies reveal that childhood hygiene is a significant risk factor for development of inflammatory bowel disease, thereby reinforcing the hygiene hypothesis and the potential importance of microbial colonization during early life. The extent to which early-life environment impacts on microbial diversity of the adult gut and subsequent immune processes has not been comprehensively investigated thus far. We addressed this important question using the pig as a model to evaluate the impact of early-life environment on microbe/host gut interactions during development. Results: Genetically-related piglets were housed in either indoor or outdoor environments or in experimental isolators. Analysis of over 3,000 16S rRNA sequences revealed major differences in mucosa-adherent microbial diversity in the ileum of adult pigs attributable to differences in earlylife environment. Pigs housed in a natural outdoor environment showed a dominance of Firmicutes, in particular Lactobacillus, whereas animals housed in a hygienic indoor environment had reduced Lactobacillus and higher numbers of potentially pathogenic phylotypes. Our analysis revealed a strong negative correlation between the abundance of Firmicutes and pathogenic bacterial populations in the gut. These differences were exaggerated in animals housed in experimental isolators. Affymetrix microarray technology and Real-time Polymerase Chain Reaction revealed significant gut-specific gene responses also related to early-life environment. Significantly, indoorhoused pigs displayed increased expression of Type 1 interferon genes, Major Histocompatibility Complex class I and several chemokines. Gene Ontology and pathway analysis further confirmed these results.

Neonatal environment exerts a sustained influence on the development of the intestinal microbiota and metabolic phenotype

The postnatal environment, including factors such as weaning and acquisition of the gut microbiota, has been causally linked to the development of later immunological diseases such as allergy and autoimmunity, and has also been associated with a predisposition to metabolic disorders. We show that the very early-life environment influences the development of both the gut microbiota and host metabolic phenotype in a porcine model of human infants. Farmpiglets were nursed by their mothers for 1 day, before removal to highly controlled, individual isolators where they received formula milk until weaning at 21 days. The experiment was repeated, to create two batches, which differed only in minor environmental fluctuations during the first day. At day 1 after birth, metabolic profiling of serum by 1H nuclear magnetic resonance spectroscopy demonstrated significant, systemic, inter-batch variation which persisted until weaning. However, the urinary metabolic profiles demonstrated that significant inter-batch effects on 3-hydroxyisovalerate, trimethylamine-N-oxide and mannitol persisted beyond weaning to at least 35 days. Batch effects were linked to significant differences in the composition of colonic microbiota at 35 days, determined by 16 S pyrosequencing. Different weaning diets modulated both the microbiota and metabolic phenotype independently of the persistent batch effects. We demonstrate that the environment during the first day of life influences development of the microbiota and metabolic phenotype and thus should be taken into account when interrogating experimental outcomes. In addition, we suggest that intervention at this early time could provide ‘metabolic rescue’ for at-risk infants who have undergone aberrant patterns of initial intestinal colonisation.

A critical evaluation of the ability of the Spinning Enhanced Visible and Infrared Imager (SEVIRI) thermal infrared red-green-blue rendering to identify dust events: theoretical analysis

Using a combination of idealized radiative transfer simulations and a case study from the first field campaign of the Saharan Mineral Dust Experiment (SAMUM) in southern Morocco, this paper provides a systematic assessment of the limitations of the widely used Spinning Enhanced Visible and Infrared Imager (SEVIRI) red-green-blue (RGB) thermal infrared dust product. Both analyses indicate that the ability of the product to identify dust, via its characteristic pink coloring, is strongly dependent on the column water vapor, the lower tropospheric lapse rate, and dust altitude. In particular, when column water vapor exceeds ∼20–25 mm, dust presence, even for visible optical depths of the order 0.8, is effectively masked. Variability in dust optical properties also has a marked impact on the imagery, primarily as a result of variability in dust composition. There is a moderate sensitivity to the satellite viewing geometry, particularly in moist conditions. The underlying surface can act to confound the signal seen through variations in spectral emissivity, which are predominantly manifested in the 8.7μm SEVIRI channel. In addition, if a temperature inversion is present, typical of early morning conditions over the Sahara and Sahel, an increased dust loading can actually reduce the pink coloring of the RGB image compared to pristine conditions. Attempts to match specific SEVIRI observations to simulations using SAMUM measurements are challenging because of high uncertainties in surface skin temperature and emissivity. Recommendations concerning the use and interpretation of the SEVIRI RGB imagery are provided on the basis of these findings.

NEONATAL HANDLING AND THE MATERNAL ODOR PREFERENCE IN RAT PUPS: INVOLVEMENT OF MONOAMINES AND CYCLIC AMP RESPONSE ELEMENT-BINDING PROTEIN PATHWAY IN THE OLFACTORY BULB

Early-life environmental events, such as the handling procedure, can induce long-lasting alterations upon several behavioral and neuroendocrine systems. However, the changes within the pups that could be causally related to the effects in adulthood are still poorly understood. In the present study, we analyzed the effects of neonatal handling on behavioral (maternal odor preference) and biochemical (cyclic AMP response element-binding protein (CREB) phosphorylation, noradrenaline (NA), and serotonin (5-HT) levels in the olfactory bulb (OB)) parameters in 7-day-old male and female rat pups. Repeated handling (RH) abolished preference for the maternal odor in female pups compared with nonhandled (NH) and the single-handled (SH) ones, while in RH males the preference was not different than NH and SH groups. In both male and female pups, RH decreased NA activity in the OB, but 5-HT activity increased only in males. Since preference for the maternal odor involves the synergic action of NA and 5-HT in the OB, the maintenance of the behavior in RH males could be related to the increased 5-HT activity, in spite of reduction in the NA activity in the OB. RH did not alter CREB phosphorylation in the OB of both male and females compared with NH pups. The repeated handling procedure can affect the behavior of rat pups in response to the maternal odor and biochemical parameters related to the olfactory learning mechanism. Sex differences were already detected in 7-day-old pups. Although the responsiveness of the hypothalamic-pituitary-adrenal axis to stressors is reduced in the neonatal period, environmental interventions may impact behavioral and biochemical mechanisms relevant to the animal at that early age.
