Improving food and nutritional security of small and marginal coconut growers through diversification of crops and enterprises

This paper presents the impact of integrating interventions like nutrition gardening, livestock rearing, product diversification and allied income generation activities in small and marginal coconut homesteads along with nutrition education in improving the food and nutritional security as well as the income of the family members. The activities were carried out through registered Community Based Organizations (CBOs) in three locations in Kerala, India during 2005-2008. Data was collected before and after the project periods through interviews using a pre-tested questionnaire containing statements indicating the adequacy, quality and diversity of food materials. Fifty respondents each were randomly selected from the three communities, thereby resulting in a total sample size of 150. The data was analysed using SPSS by adopting statistical tools like frequency, average, percentage analysis, t – test and regression. Participatory planning and implementation of diverse interventions notably intercropping and off-farm activities along with nutrition education brought out significant improvements in the food and nutritional security, in terms of frequency and quantity of consumption as well as diet diversity. At the end of the project, 96%of the members became completely food secure and 72% nutritionally secure. The overall consumption of fruits, vegetables and milk by both children and adults and egg by children recorded increase over the project period. Consumption of fish was more than the Recommended Dietary Intake (RDI) level during pre and post project periods. Project interventions like nutrition gardening could bring in surplus consumption of vegetables (35%) and fruits (10%) than RDI. In spite of the increased consumption of green leafy vegetables and milk and milk products over the project period, the levels of consumption were still below the RDI levels. CBO-wise analysis of the consumption patterns revealed the need for location-specific interventions matching to the needs and preferences of the communities.

Calidad de vida en personas con hemofilia: una revisión de la literatura

Introducción: La hemofilia es una enfermedad poco frecuente; no obstante, los avances en los tratamientos de pacientes hemofílicos en las últimas décadas han generado cambios en su calidad de vida. Esto ha motivado el desarrollo de múltiples investigaciones al respecto. Objetivo: Revisar la literatura sobre la calidad de vida en el paciente hemofílico, producida en el periodo 2008-2012. Método: Se consultaron algunas bases de datos científicas utilizando como palabras clave “hemofilia” y “calidad de vida”. Se recopiló la información encontrada y se organizó según los objetivos propuestos en “factores negativos” y “factores protectores” de la calidad de vida a nivel fisiológico, psicosocial y cultural; “instrumentos para la evaluación de la calidad de vida” a nivel específico y general; y antecedentes empíricos de los últimos cinco años en los que se evaluara la calidad de vida o se realizara alguna intervención en la misma. Resultados: En general la información disponible sobre el comportamiento epidemiológico de la hemofilia es limitada. El interés por factores protectores y negativos es principalmente de tipo fisiológico, aunque se encontraron factores de tipo psicosocial y cultural, lo que indica la importancia de profundizar en esta temática. Existen pocos instrumentos especializados para la evaluación de la calidad de vida en hemofílicos. La evidencia empírica se centra en la evaluación. Conclusión: El estudio de la calidad de vida en pacientes hemofílicos amerita ser abordado de manera interdisciplinaria.

Diferencias entre la regla de exclusión probatoria nacional y la regla de exclusión del Derecho Internacional Penal: análisis de tres casos de injerencias en comunicaciones privadas.

Teniendo en cuenta tres casos dentro del contexto del conflicto armado donde la jurisdicción penal colombiana estudia la admisión o exclusión de medios probatorios producidos a partir de injerencias de comunicaciones, encontramos que no siempre se aplica la regla de exclusión cuando no cuentan con una orden judicial previa. Ante este problema, buscamos como se ha solucionado, teniendo como referente la el Derecho Internacional Humanitario, el Derecho Internacional de los Derechos Humanos. Lo anterior nos da base para entender la regla de exclusión de que se ha venido desarrollando dentro del Derecho Internacional Penal. Si bien estas reglas nos sirven para solucionar estos tres casos, terminan siendo contradictorios a lo que ha venido desarrollando la Corte Constitucional. De esta manera, si bien esta Corte consideró que la regla de Estatuto de Roma, va en concordancia con la nuestra regla de exclusión nacional, tal afirmación es errónea.

Efectos de la asociación vasopresina-noradrenalina en pacientes pediátricos con choque séptico refractario

Objetivo: Evaluar el efecto sobre presión arterial media (PAM), estancia hospitalaria, mortalidad y perfusión tisular con el uso de vasopresores en niños con choque séptico refractario en la Unidad de Cuidado Intensivo pediátrico de la Fundación CardioInfantil. Materiales y Métodos: Estudio observacional de cohorte retrospectiva en niños de 1 mes a 18 años con choque séptico refractario atendidos de enero 2008 a diciembre 2013 tratados con noradrenalina sola ó vasopresina-noradrenalina. Se excluyeron pacientes con choque de otra etiología, cardiopatías congénitas, diabetes insípida y muerte encefálica. Se estimaron, como medidas de asociación riesgos relativos con sus respectivos intervalos de confianza al 95%.Resultados: Se evaluaron 129 pacientes, de los cuales 51% eran niños, edad promedio 52 meses con una mortalidad global del 34.1%. La PAM inicial en ambos grupos mostró incremento significativo que se mantuvo en las siguientes 3 horas (p<0,005). La mortalidad en el grupo PRISM III de bajo riesgo fue menor con la noradrenalina sola (p<0,005 RR3,7 IC95% 1,16-12,2) pero igual en ambos grupos en los de riesgo moderado según esta escala(p=0,42 RR 0,88 IC95% 0,60-1,30). No se encontraron diferencias estadísticamente significativas en estancia en UCIP (p=0,79) ni hospitalaria total (p=0,96) pero sí mejoría en función hepática (p=0,004)y renal (p<0,005) del grupo de vasopresina-noradrenalina Conclusiones: La asociación vasopresina-noradrenalina mejora la PAM cuando no se han alcanzado metas con un solo vasopresor en pacientes con choque séptico refractario. Se necesitan estudios prospectivos que corroboren estos hallazgos. Palabras claves:Choque séptico refractario, noradrenalina, vasopresina, mortalidad.

Bt cotton, pesticides, labour and health - A case study of smallholder farmers in the Makhathini Flats, Republic of South Africa

This paper describes some of the results of a detailed farm-level survey of 32 small-scale cotton farmers in the Makhathini Flats region of South Africa. The aim was to assess and measure some of the impacts (especially in terms of savings in pesticide and labour as well as benefits to human health) attributable to the use of insect-tolerant Bt cotton. The study reveals a direct cost benefit for Bt growers of SAR416 ($51) per hectare per season due to a reduction in the number of insecticide applications. Cost savings emerged in the form of lower requirements for pesticide, but also important were reduced requirements for water and labour. The reduction in the number of sprays was particularly beneficial to women who do some spraying and children who collect water and assist in spraying. The increasing adoption rate of Bt cotton appears to have a health benefit measured in terms of reported rates of accidental insecticide poisoning. These appear to be declining as the uptake of Bt cotton increases. However, the understanding of refugia and their management by local farmers are deficient and need improving. Finally, Bt cotton growers emerge as more resilient in absorbing price fluctuations.

Pyrohydrolysis-IRMS determination of silicate chlorine stable isotope compositions. Application to oceanic crust and meteorite samples

This contribution describes the optimization of chlorine extraction from silicate samples by pyrohydrolysis prior to the precise determination of Cl stable-isotope compositions (637 Cl) by gas source, dual inlet Isotope Ratio Mass Spectrometry (IRMS) on CH(3)Clg. The complete method was checked on three international reference materials for Cl-content and two laboratory glass standards. Whole procedure blanks are lower than 0. 5 mu mol, corresponding to less than 10 wt.% of most of the sample chloride analysed. In the absence of international chlorine isotope rock, we report here Cl extracted compared to accepted Cl contents and reproducibilities on Cl and delta Cl-37 measurements for the standard rocks. After extraction, the Cl contents of the three international references compared within error with the accepted values (mean yield = 94 +/-10%) with reproducibilities better than 12% (10). The laboratory glass standards - andesite SO100DS92 and phonolite S9(2) - were used specifically to test the effect of chloride amount on the measurements. They gave Cl extraction yields of 100 +/-6% (1 sigma-; n = 15) and 105 +/- 8% (1 sigma-; n = 7), respectively, with delta Cl-37 values of -0.51 0.14%o and -0.39 0.17%o (1g). In summary, for silicate samples with Cl contents between 39 and 9042 ppm, the Pyrohydrolysis/HPLC method leads to overall CI extraction yields of 100 8%, reproducibilities on Cl contents of 7% and on delta Cl-37 measurements of 0.12%o (all 1 sigma). The method was further applied to ten silicate rocks of various mineralogy and chemistry (meteorite, fresh MORB glasses, altered basalts and setpentinized peridotites) chosen for their large range of Cl contents (70-2156 ppm) and their geological significance. delta Cl-37 values range between -2.33 and -0.50%o. These strictly negative values contrast with the large range and mainly positive values previously reported for comparable silicate samples and shown here to be affected by analytical problems. Thus we propose a preliminary, revised terrestrial CI cycle, mainly dominated by negative and zero delta Cl-37 values. (C) 2007 Elsevier B.V. All rights reserved.

Seasonal trends in the stable isotopic composition of snow and meltwater runoff in a subarctic catchment at Okstindan, Norway

Seasonal variations in the stable isotopic composition of snow and meltwater were investigated in a sub-arctic, mountainous, but non-glacial, catchment at Okstindan in northern Norway based on analyses of delta(18)O and deltaD. Samples were collected during four field periods (August 1998; April 1999; June 1999 and August 1999) at three sites lying on an altitudinal transect (740-970 m a.s.l.). Snowpack data display an increase in the mean values of delta(18)O (increasing from a mean value of - 13.51 to - 11.49% between April and August), as well as a decrease in variability through the melt period. Comparison with a regional meteoric water line indicates that the slope of the delta(18)O - deltaD line for the snowpacks decreases over the same period, dropping from 7.49 to approximately 6.2. This change points to the role of evaporation in snowpack ablation and is confirmed by the vertical profile of deuterium excess. Snowpack seepage data, although limited, also suggest reduced values of deltaD, as might be associated with local evaporation during meltwater generation. In general, meltwaters were depleted in delta(18)O relative to the source snowpack at the peak of the melt (June), but later in the year (August) the difference between the two was not statistically significant. The diurnal pattern of isotopic composition indicates that the most depleted meltwaters coincide with the peak in temperature and, hence, meltwater production.

Effects of carbon dioxide on the searching behaviour of the root-feeding clover weevil Sitona lepidus (Coleoptera : Curculionidae)

The respiratory emission of CO2 from roots is frequently proposed as an attractant that allows soil-dwelling insects to locate host plant roots, but this role has recently become less certain. CO2 is emitted from many sources other than roots, so does not necessarily indicate the presence of host plants, and because of the high density of roots in the upper soil layers, spatial gradients may not always be perceptible by soil-dwelling insects. The role of CO2 in host location was investigated using the clover root weevil Sitona lepidus Gyllenhall and its host plant white clover (Trifolium repens L.) as a model system. Rhizochamber experiments showed that CO2 concentrations were approximately 1000 ppm around the roots of white clover, but significantly decreased with increasing distance from roots. In behavioural experiments, no evidence was found for any attraction by S. lepidus larvae to point emissions of CO2, regardless of emission rates. Fewer than 15% of larvae were attracted to point emissions of CO2, compared with a control response of 17%. However, fractal analysis of movement paths in constant CO2 concentrations demonstrated that searching by S. lepidus larvae significantly intensified when they experienced CO2 concentrations similar to those found around the roots of white clover (i.e. 1000 ppm). It is suggested that respiratory emissions of CO2 may act as a 'search trigger' for S. lepidus, whereby it induces larvae to search a smaller area more intensively, in order to detect location cues that are more specific to their host plant.

"Mad dogs and transnational migrants?" Bajan-Brit second-generation migrants and accusations of madness

Second-generation British-Barbadians ("Bajan-Brits'') returning to the land of their parents are frequently accused by indigenous Barbadian nationals of being mad. Narratives of the migrants reflect four major sets of factors: (1) madness as perceived behavioral and cultural differences; (2) explanations that relate to the historical-clinical circumstances surrounding the incidence of mental ill health among first-generation West Indian migrants to the United Kingdom; (3) madness as a pathology of alienation that is attendant on living in Barbados; and (4) madness as "othering,'' "outing,'' and "fixity.'' British second-generation "returning nationals'' to the Caribbean, living as they do in the plural world of the land of their parents' birth, after having been raised in the colonial "Mother Country,'' exhibit hybridity and in-betweenness. Accusations of madness serve to fix the position of these young migrants outside the mainstream of indigenous Barbadian society. Our analysis invokes recent postcolonial writings dealing with "strange encounters'' to theorize that the madness accusation serves to "other'' the young Bajan-Brit migrants in a strongly postcolonial context.

Simultaneous analysis of v1, v4, 2v2, v2+v5, and 2v5 bands of 12CH3F

The Fourier-transform spectrum of CH3F from 2800 to 3100 cm−1, obtained by Guelachvili in Orsay at a resolution of about 0.003 cm−1, was analyzed. The effective Hamiltonian used contained all symmetry allowed interactions up to second order in the Amat-Nielsen classification, together with selected third-order terms, amongst the set of nine vibrational basis functions represented by the states ν1(A1), ν4(E), 2ν2(A1), ν2 + ν5(E), 2ν50(A1), and 2ν5±2(E). A number of strong Fermi and Coriolis resonances are involved. The vibrational Hamiltonian matrix was not factorized beyond the requirements of symmetry. A total of 59 molecular parameters were refined in a simultaneous least-squares analysis to over 1500 upper-state energy levels for J ≤ 20 with a standard deviation of 0.013 cm−1. Although the standard deviation remains an order of magnitude greater than the precision of the measurements, this work breaks new ground in the simultaneous analysis of interacting symmetric top vibrational levels, in terms of the number of interacting vibrational states and the number of parameters in the Hamiltonian.
