Niveles de vitamina d y prevalencia de déficit de vitamina d en mujeres postmenopáusicas mayores de 50 años en Bogotá

Objetivo: Describir los niveles de vitamina D y calcular prevalencia de déficit de vitamina D en mujeres postmenopáusicas mayores de 50 años que asisten a consulta de medicina general en una muestra en de la ciudad de Bogotá durante el periodo 2013-2014. Pacientes y métodos: Realizamos un estudio descriptivo para estimar el déficit de VD en mujeres postmenopáusicas entre 50 y 80 años en la ciudad de Bogotá y la prevalencia de hipovitaminosis D. Durante el periodo octubre 2013 a octubre 2014 se analizaron 320 muestras, se identificaron las características socio-demográficas, patológicas y la exposición a radiación ultravioleta de cada participante. Se realizó un análisis descriptivo de las variables, se estableció su asociación con el déficit de vitamina D su aporte estadístico con al mismo. Resultados :El promedio de edad en la muestra fue de 61 años y el promedio de edad en la que reportaron la ultima menstruación fue a los 43 años. Con respecto a las características socio-demográficas 50% de las mujeres pertenecieron a los estratos 3 y 4, únicamente 11% de los pacientes realizaron una carrera universitaria y 73% de la mujeres fueron amas de casa. Con respecto a los niveles de vitamina D, 81% de los pacientes presentaron niveles anormales y el promedio de 25(OH)D en la población estudio fue de 19,81ng/ml. Conclusión: La prevalencia de déficit de vitamina D en mujeres bogotanas postmenopáusicas es significativo. Se requiere incrementar la exposición solar o dar suplencia con vitamina D para disminuir el riesgo de fracturas.

La cooperación en América del Norte : de las seguridades económica y militar a la bioseguridad (2001-2009)

El nuevo orden internacional derivado de la Guerra Fría se caracterizó por la multiplicación de nuevas amenazas a la seguridad y la construcción de bloques regionales con el propósito de enfrentarlas. Esta investigación plantea que bajo tales circunstancias, en América del Norte, fue adoptada una agenda ampliada y profundizada en materia de seguridad que permitió articular las seguridades económica, militar y la bioseguridad. En este sentido, la configuración de dicha agenda fue posible gracias a la adopción de una retórica neoliberal de seguridad económica desde la puesta en marcha del Tratado de Libre Comercio en 1994, la cual luego del 11 de septiembre de 2001 fue articulada con la agenda de seguridad militar propuesta por el gobierno estadounidense en materia de lucha antiterrorista, que a su turno permitió la adopción de una retórica y unas medidas extraordinarias en materia de bioseguridad, motivada por los ataques bioterroristas con ántrax en EE.UU., el brote de SARS en Canadá y la pandemia de AH1N1 en México.

Atención a la diversidad desde la calidad y la equidad en la educación básica.

Propiciar que quienes influyen en la política y en la administración pública en México, promuevan acciones de cambio sensibles a la complejidad ideológica, cultural, social, organizativa y personal de los distintos centros escolares, tratando de mejorar la calidad del sistema educativo con equidad y principalmente con respeto a la diversidad. Precisar los límites conceptuales y operativos de la política de la educación orientada a la calidad y la equidad, con el propósito de ampliar su margen y sus alcances en la vida cotidiana del trabajo escolar. Documentos legales y discursos del presidente Ernesto Zedillo, y 184 docentes que trabajaban en escuelas de educación obligatoria en el estado de Nuevo León, México. Se realiza una síntesis de las principales acciones que han repercutido en la educación básica a lo largo de la historia, tanto en el ámbito nacional, como en lo relacionado con el estado de Nuevo León, México. Se sintetiza la información más relevante de los documentos legales que han favorecido la última reforma educativa al Sistema Educativo Mexicano. Se seleccionan los discursos del Presidente Ernesto Zedillo (1994-2000) en los que haya hecho referencia a la educación básica y se analiza su contenido. También se elabora y se aplica una escala de valor por conocer el tipo de actuación de docentes y personal en funciones directivas en torno al compromiso con la calidad, el impulso a la equidad y el respeto a la diversidad. Se elabora una escala para analizar la práctica escolar cotidiana y conocer el tipo de actuación en torno a las relaciones entre la práctica escolar cotidiana y el compromiso con la calidad, el impulso a la equidad y el respeto a la diversidad, que llamaron REPECCED. Hojas de ruta. Según demuestra el estudio, existen evidencias de que los Gobiernos de México durante los períodos 1988-1994 y 1994-2000, han enfocado sus esfuerzos en educación básica a impulsar la mejora de la calidad y otorgarla con mayor equidad. La propuesta del autor gira en torno a la idea de que en el período de gobierno 2000-2006 se deberán enfocar los esfuerzos a establecer acciones que promuevan el respeto a la diversidad y que permitan concretar y afianzar el desarrollo académico para satisfacer las necesidades educativas de la población mexicana en edad escolar.

Legislación del Ecuador y agricultura para exportación dentro del proceso de apertura económica

En la proximidad del siglo XXI la agricultura ecuatoriana enfrenta grandes desafíos. La enorme transformación Internacional y los espectaculares avances tecnológicos, han llevado a la globalización de la economía mundial generando nuevas formas de organización y de competencia y aumentado fuertemente la interdependencia económica entre los paises. Además la adhesión del Ecuador al GATT-OMC han modificado las reglas del comercio agrícola, tomando en cuenta que tanto las orientaciones del crecimiento como los agentes y las prioridades del desarrollo son actualmente distintas a las del modelo anterior. El acceso de los productos agrícolas de exportación ecuatorianos a los mercados internacionales es afectado a nivel externo, por el proteccionismo desleal de• parte de los países industrializados especialmente de Estados Unidos, y la Unión Europea, los mercados principales del comercio exterior ecuatoriano, en un mercado distorsionado medidas y que se supone debe estar liberado de este tipo de prácticas en la actual época donde el liberalismo es la doctrina vigente. Y a nivel interno, la presente investigación confirma la incoherencia de las políticas gubernamentales del Ecuador en el sector agropecuario, a partir del análisis de tres pilares: enunciados del gobierno, cambios en el marco legal de productos agricolas de exporta ión y la evolución de las cifras sobre gasto publico agropecuario en el periodo 1988-1994. Esta falta de definición esta ocasionando el fracaso de los intentos del pais para orientar su desarrollo hacia el exterior, y la disminución de la presencia comercial del Ecuador en el contexto mundial con participaciones marginales en las exportaciones regionales e incluso mundiales.

Trade liberalization and industrial concentration: evidence from Brazil

This paper applies an endogenous lobby formation model to explain the extent of trade protection granted to Brazilian manufacturing industries during the 1988- 1994 trade liberalization episode. Using a panel data set covering this period, we find that even in an environment in which a major regime shift has been introduced, more concentrated sectors have been able to obtain policy advantages, that lead to a reduction in international competition. The importance of industry structure appears to be substantial: In our baseline specification, an increase in concentration by 20% leads to an increase in protection by 5%-7%.

O ecoturismo sob a égide da sociedade do consumo: um estudo das Unidades de Conservação de uso sustentável do RN

Ecotourism, in face to environmental demands and discussions, has achieved prominence in the tourism market and wide global development, occasioning a concern about the need for a scientific deepening through a critical approach of the dynamics of consumption and conservation that permeate this practice. This study addresses the ecotourism under aegis of consumer society, in which is perceived that it constitutes a contester practice of society in which it is embedded, nevertheless has been subjected to the logic of capital through commodification of nature. In order to comprehend the reality presented, this study had as geographical cutting two Conservation Units of Sustainable Use in Rio Grande do Norte state: the Jenipabu Environmental Protection Area (APAJ) and Ponta do Tubarão State Sustainable Development Reserve (RDSEPT). The research sought to investigate the relationship between conservation and consumption and their influences on ecotourism held in the Conservation Units (UCs) of sustainable use selected for this study. To this aim it was made a critical reflection about the relationship conservation versus consumption constant in the practice of ecotourism in UCs in the context of current society, analyzing the historical process of formation of UCs of sustainable use in RN state under the light of the contradictory pair conservation-consumption, as well as looking to apprehend the perception of ecotourism of the actors involved with this practice. It was adopted a qualitative approach under a critical perspective based on bibliographical and documentary research and realization of semi-structured interviews with three groups of actors, namely managers/technician, community and ectourists involved with ecotourism in the selected UCs. The analysis was made using two basic units of analysis (consumption and maintenance) and twelve categories. For definition of units of analysis and categories were taken as reference the authors Santos (1987; 1988; 1994; 2001; 2006), Guerreiro Ramos (1989) and A. B. Rodrigues (1996; 2003), which perform critical to society of consumption and describe the key characteristics of the technical-scientific-informational predominant means, and Diegues (1998; 2000), A. B. Rodrigues (2001), Pires (2002) and Neiman and Rabinovici (2010), which discusse historic and scientifically about the emphasis on conservation present in origins and discourse of ecotourism, describing also its founding characteristics. The main results show that the marketing use of the prefix eco has acted as a new dress for what in reality is in fact ancient, ie, the conservation is used as a justification for another new type of consumption. The results also show that despite the coexistence of commercial and symbolic intentions in both UCs, one can observe the predominance consumer society characteristics in the process of creation and the production activities of APAJ, while in RDSEPT we note the predominance of the conservationist characteristics proclaimed by ecotourism. It can be inferred therefore that tourism held in the APAJ can not be called ecotourism, while the practice found in RDSEPT show an alignment with the guidelines of ecotourism

Estudo multitemporal da dinâmica espacial do estuário Potengi/RN, utilizando como base os dados de Sensoriamento Remoto.

This work was developed in the Potengi river estuary, northern coastal city of Natal, located in the State of Rio Grande do Norte. The objective was to study the dynamics of Multitemporal Space in that estuary, however, analyze how this environment has behaved during the years 1988, 1994 and 2006. The definition of that, there was the fact that during that period, which occurred in that area and more intensive space exploration to practice economic activities as well as a greater and more rapid expansion of urban area. This study was supported by the Remote Sensing, who have been shown today, as an efficient analysis of the environmental studies, through geoprocessing techniques. From the performed analysis it was found that occurred during the period of study (1988 to 2006), a huge change in the design of the estuary of Potengi river. The figures showed the area of vegetation was decreased 65.22%, the deforested area increased by 70.44% and the shrimp activity grow 452.07% and the urban area was increased in 52.65% along that period described. Considering the numbers shown there that the process of occupying space in that area requires attention, because it is an environment that represents a huge contribution to the ecological balance.

Dyslexic children suffer from less informative visual cues to control posture

The goal of this study was to investigate the effects of manipulation of the characteristics of visual stimulus on postural control in dyslexic children. A total of 18 dyslexic and 18 non-dyslexic children stood upright inside a moving room, as still as possible, and looked at a target at different conditions of distance between the participant and a moving room frontal wall (25-150 cm) and vision (full and central). The first trial was performed without vision (baseline). Then four trials were performed in which the room remained stationary and eight trials with the room moving, lasting 60 s each. Mean sway amplitude, coherence, relative phase, and angular deviation were calculated. The results revealed that dyslexic children swayed with larger magnitude in both stationary and moving conditions. When the room remained stationary, all children showed larger body sway magnitude at 150 cm distance. Dyslexic children showed larger body sway magnitude in central compared to full vision condition. In the moving condition, body sway magnitude was similar between dyslexic and non-dyslexic children but the coupling between visual information and body sway was weaker in dyslexic children. Moreover, in the absence of peripheral visual cues, induced body sway in dyslexic children was temporally delayed regarding visual stimulus. Taken together, these results indicate that poor postural control performance in dyslexic children is related to how sensory information is acquired from the environment and used to produce postural responses. In conditions in which sensory cues are less informative, dyslexic children take longer to process sensory stimuli in order to obtain precise information, which leads to performance deterioration.

Resisting Postmodernity: Swedish social policy in the 1990s

The purpose of this paper is to introduce ideas that have emerged during the course of writing a book on Swedish welfare in the 1990s. The book is the result of many years of writing about two subjects: Swedish drug policy and the Swedish welfare state. The one very specialised, the other, more general. I first became interested in Swedish drug policy on a research visit to Örebro Län in 1986. A social worker showed me a copy of the county's drug policy programme and explained the significance of the 'restrictive line'. I have spent the years since that visit, trying to understand and explain the Swedish goal of a drug-free society (Gould 1988, 1994, 1996b). I only began to write about the welfare state in Sweden in the early 1990s, just as things were beginning to go wrong for the economy (Gould 1993a, 1993b, 1996a, 1999). For the last few years I have intended to write a book on the events covered by the period 1991-1998 - the years of a Bourgeois and a Social Democratic Government -which would bring the two halves of my work together. Material for this study has been accumulated over many years. A number of research visits have been made; large numbers of academics, politicians, civil servants, journalists, unemployed people, social workers and their clients have been interviewed; and extensive use has been made of academic, administrative and public libraries. Since September 1991 I have systematically collected articles from Dagens Nyheter about social services, social insurance, health care, employment, social issues and problems, the economy and politics. The journal Riksdag och Departement (Parliament and Ministry), which summarises a wide range of public documents, has been invaluable. Friends and informal contacts have also given me insights into the Swedish way of life. The new book is based upon all of these experiences. This paper will begin with a brief account of major global social and economic changes that have occurred in the last twenty years. This is intended to provide a background to the more recent changes that have occurred in Swedish society in the last decade. It will be suggested that the changes in Sweden, particularly in the field of welfare, have been less severe than elsewhere and that this is due to political, institutional and cultural resistance. The paper will conclude by arguing that Sweden, as an exemplar of an Apollonian modern society, has had much to fear from the Dionysian characteristics of postmodernity.

The quiet eye and tasks demands: Do tougher shots need a quieter eye?

The Quiet Eye (QE; Vickers 1996) has been shown to underpin successful performance, differentiating both expertise (inter-individual) and proficiency (intra-individual), with experts and successful attempts characterised by longer QE durations. The QE is proposed to reflect the time needed to organise and fine tune the parameters of movement (e.g. force and direction). In order to examine this prediction and build upon previous research we experimentally manipulated the difficulty of a golf putting task; we hypothesised that if the QE is related to motor programming then a more difficult task should be associated with longer QE durations. 33 golfers (M age= 21.16, SD= 3.98) with an average handicap of 6.5 (SD= 6.02) performed putts in 4 conditions of increasing difficulty. We manipulated the length of the golf putt (short-4ft, long-8ft) and the contact point of the putter head (large-1.7cm, small-0.5cm,) giving increasingly difficult putting conditions of short-large [1], short-small [2], long-large [3] and long-small [4]. We measured performance (radial error from hole in cm) and QE (in ms) for 10 putts in each condition. A repeated measures ANOVA was performed on the performance and QE data. The performance data suggest that we were successful in increasing the difficulty of the task (F (3,93) = 26.46. p = .000), with the best performance in condition [1] (8.57cm), followed by [2] (9.10cm) followed by [3] (16.11cm) and finally the worst performance was in condition [4] (23.40cm). The QE data suggest that, in keeping with our hypothesis, the QE was lengthened as task difficulty increased (F (3,87) = 11.91, p = .043). The QE was shortest in condition [1] (1787.85ms) and increased to condition [2] (1939.78ms) and condition [3] (2076.51ms), with the longest QE in condition [4] (2164.08ms). More detailed analysis of the QE reveal that it was the proportion of the QE that occurred before movement initiation (pre-QE) which increased with shot difficulty, rather than the proportion that occurred during the swing (Online-QE; see Vine et al., 2013). Results support the notion that more complex tasks are associated with a longer QE duration, specifically participants appear to spend longer fixating the target prior to movement. This likely reflects the time needed to process visual information gathered in a pre-performance routine, to inhibit external distraction, and to pre-programme the increasingly difficult parameters of the movement.
