Double burden malnutrition of preschool children and its association with brain development and milk consumption

Protecting the quality of children growth and development becomes a supreme qualification for the betterment of a nation. Double burden child malnutrition is emerging worldwide which might have a strong influence to the quality of child brain development and could not be paid-off on later life. Milk places a notable portion during the infancy and childhood. Thus, the deep insight on milk consumption pattern might explain the phenomenon of double burden child malnutrition correlated to the cognitive impairments. Objective: Current study is intended (1) to examine the current face of Indonesian double burden child malnutrition: a case study in Bogor, West Java, Indonesia, (2) to investigate the association of this phenomenon with child brain development, and (3) to examine the contribution of socioeconomic status and milk consumption on this phenomenon so that able to formulate some possible solutions to encounter this problem. Design: A cross-sectional study using a structured coded questionnaire was conducted among 387 children age 5-6 years old and their parents from 8 areas in Bogor, West-Java, Indonesia on November 2012 to December 2013, to record some socioeconomic status, anthropometric measurements, and history of breast feeding. Diet and probability of milk intake was assessed by two 24 h dietary recalls and food frequency questionnaire (FFQ). Usual daily milk intake was calculated using Multiple Source Method (MSM). Some brain development indicators (IQ, EQ, learning, and memory ability) using Projective Multi-phase Orientation method was also executed to learn the correlation between double burden child malnutrition and some brain development indicator. Results and conclusions: A small picture of child double burden malnutrition is shown in Bogor, West Java, Indonesia, where prevalence of Severe Acute Malnutrition (SAM) is 27.1%, Moderate Acute Malnutrition (MAM) is 24.9%, and overnutrition is 7.7%. This phenomenon proves to impair the child brain development. The malnourished children, both under- and over- nourished children have significantly (P-value<0.05) lower memory ability compared to the normal children (memory score, N; SAM = 45.2, 60; MAM = 48.5, 61; overweight = 48.4, 43; obesity = 47.9, 60; normal = 52.4, 163). The plausible reasons behind these evidences are the lack of nutrient intake during the sprout growth period on undernourished children or increasing adiposity on overnourished children might influence the growth of hippocampus area which responsible to the memory ability. Either undernutrition or overnutrition, the preventive action on this problem is preferable to avoid ongoing cognitive performance loss of the next generation. Some possible solutions for this phenomenon are promoting breast feeding initiation and exclusive breast feeding practices for infants, supporting the consumption of a normal portion of milk (250 to 500 ml per day) for children, and breaking the chain of poverty by socioeconomic improvement. And, the national food security becomes the fundamental point for the betterment of the next. In the global context, the causes of under- and over- nutrition have to be opposed through integrated and systemic approaches for a better quality of the next generation of human beings.

Assessing the Precision of Compositional Data in a Stratified Double Stage Cluster Sample: Application to the Swiss Earnings Structure Survey

Precision of released figures is not only an important quality feature of official statistics, it is also essential for a good understanding of the data. In this paper we show a case study of how precision could be conveyed if the multivariate nature of data has to be taken into account. In the official release of the Swiss earnings structure survey, the total salary is broken down into several wage components. We follow Aitchison's approach for the analysis of compositional data, which is based on logratios of components. We first present diferent multivariate analyses of the compositional data whereby the wage components are broken down by economic activity classes. Then we propose a number of ways to assess precision

The mutual agreement procedure and arbitration of double taxation disputes

It is in the interest of most states to eliminate double taxation (i.e. the payment of the same tax in two jurisdictions) of transnational commercial enterprises. Because such disputes involve, on the one hand, the state imposition of taxes, a right universally asserted by all states, and private entities on the other, taxation disputes between such parties are not, on their face, easily susceptible to arbitration. This article analyzes two dispute settlement procedures-the OECD First Model Tax Convention and a similar EU Convention-with the exclusive focus on disputes relating to the imposition of double taxation. It will look at the ways in which state roles may vary under these procedures from assisting in the negotiation process to taking a part similar to, but with important differences from, diplomatic protection on behalf of an affected enterprise. The article will examine the situations under which the settlement procedure is required and/or available, how the procedures are triggered, the obligations and parts played by the parties, the means by which the disputes are resolved (from negotiations to tribunals) and the limitations of the procedures. Are they “taxpayer friendly”? As a result the reader may draw comparisons between the two procedures. Finally, the article will look at the proposed OECD Arbitration Clause which is intended to be incorporated into Article 25 of the OECD Model Tax Convention as well as how these mechanisms relate and/or conflict with bilateral tax treaties and the GATS.

Loss of nerve fiber layer in HIV positive patients and comparative patterns in a series of cases in Bucaramanga, Colombia

Objective: The objective of this study is to conduct a description of the features of optic neuropathy associated with Human Immunodeficiency Virus in relation to their possible incidence within our population, regarding that there is no data in our population in terms of frequency of this pathology (1,2). Methodology: Descriptive cross-sectional study of a clinical series of patients infected with human immunodeficiency virus, but AIDS, and the thickness of optic nerve´s layer of fibers studied with OCT technology (optical coherence tomography), patients were cited once captured. OCT was performed by the same observer, by taking 3 shots and picking the one with better reliability. Patients were given personally to the Ophthalmologic Foundation of Santander to conduct the review called OCT (optical coherence tomography). Results: In terms of viral load variable, we found a clear correlation in which validates the hypothesis that lower viral load means a thicker layer of fibers finding statistically significant differences for the 6 hours in right eye and 12 and 6 hours in left eye. Comparison between the known nomogram of fiber layer thickness for the population of Bucaramanga, Santander and thickness found in our sample, we note a clear decrease in the upper and lower quadrants, specifically in 7 hours and 11 hours, being more important in 7 hours, showing statistically significant differences. Conclusions: The pattern  of thinning of the nerve fiber layer in HIV positive patients without AIDS, and antiretroviral treatment type HAART, showed a statistically significant thinning targeted at 7 hours and 11 hours, being higher in first. Viral load figures have a direct relation with loss fiber layer, showing a statistically significant difference for the 6 and 12 hours.

A Monte Carlo-Based Fiber Tracking Algorithm using Diffusion Tensor MRI

Diffusion tensor magnetic resonance imaging, which measures directional information of water diffusion in the brain, has emerged as a powerful tool for human brain studies. In this paper, we introduce a new Monte Carlo-based fiber tracking approach to estimate brain connectivity. One of the main characteristics of this approach is that all parameters of the algorithm are automatically determined at each point using the entropy of the eigenvalues of the diffusion tensor. Experimental results show the good performance of the proposed approach

Modificació de fibres de jute per l'elaboració de plàstics reforçats reciclables

El treball que s'ha dut a terme es centra en la recerca d'agents modificants per a fibres cel·lulòsiques capaços de reduir la polaritat de les funcions alcohol de la seva estructura per formació de funcions ester. Les fibres de jute se sotmeten a reacció en un sistema tancat provist d'atmòsfera de nitrogen a fi d'evitar reaccions laterals que no són del nostre interés.L'obtenció dels resultats perseguits està lligat a les condicions experimentals aplicades durant les reaccions. La influència de les diferents variables escollides facilitarà en major o menor grau la reacció entre les molècules d'agent d'acoblament i cel·lulosa vinculades. Una gran part de l'atenció es centrarà en l'estudi de l'etapa de modificació, sobretot en l'efectivitat dels reactius addicionats per la reacció amb els grups hidroxil. Un cop comparats els experiments realitzats tant amb clorur d'oleïl com amb anhídrid metacrílic, es conclou que la majoria de condicions provades permeten assolir valors de modificació prou significatius. L'excepció ve donada quan la temperatura utilitzada és de 20ºC, llavors les mateixes condicions que a una temperatura de 60ºC condueixen cap a resultats poc satisfactoris. La reactivitat per part dels dos agents d'acoblament utilitzats no ha estat la mateixa. Els resultats per condicions experimentals del mateix tipus han conduït cap a valors força diferents. Pel que fa a la determinació dels paràmetres òptims es conclou que les variables amb les que el grau de modificació millora considerablement són: una temperatura de 60ºC, 10% de catalitzador respecte la quantitat de clorur d'oleïl o anhídrid addicionada, relació OH reactiu estequiomètrica 1:1 i 40mL de solvent. Un cop modificada la fibra, se sotmet a reacció amb el monòmer estirè. Es comprova que el grau de polimerització segueix el valor de modificació prèviament obtingut, a menor quantitat de funcions alcohol lliures major interacció amb el monòmer estirè. Les propietats inicials de la fibra no es corresponen amb les obtingudes després del tractament, l'increment de la resistència a l'atac de microorganismes i a l'absorció d'humitat s'explica per una reducció de la presència de funcions alcohol polars i per la capa d'estirè polimeritzat per unió amb els dobles enllaços introduïts amb els agents d'acoblament. Pel que fa referència a les dues tècniques de caracterització més utilitzades, l'anàlisis elemental permet quantificar d'una manera precisa la reacció de la fibra amb els agents d'acoblament i la posterior reacció de la fibra modificada amb el monòmer estirè. La caracterització per espectroscopia d'infraroig permet comprovar qualitativament la reactivitat del clorur d'oleïl i qualitativament-quantitativament la de l'anhídrid metacrílic amb les funcions alcohol de la cel·lulosa present en les fibres de jute. Els pics més característics apareguts seran utilitzats per avaluar la reactivitat de la funció carbonílica del reactiu modificant amb l'estructura cel·lulòsica i del doble enllaç de la cel·lulosa modificada amb la matriu polimèrica.

Texte de présentation sur les concepts muséologiques dans leurs rapports avec les systèmes muséologiques actuels responsables de bouleversements: une double hystérie ?

Les concepts, les notions, les langages qui en découlent, sont intimement lies aux systèmes et aux contextes qui alimentent la forme et la vie du musée. Depuis que la question se pose, où va la muséologie qui a emprunté la voie du changement dans les années 70, 80 et 90, une réflexion sur les principaux vecteurs de transformation de l’institution dex fois séculaire s’impose. Bien que la plupart des musées et de ses dérivatifs (60%) possédant une crédibilité dans le monde occidental , malgré les réformes de modernisation introduites ( attention aux publics, presentation améliorée ) demeurent attachés à la tradition qui en determine l’image, on peut affirmer, sans se tromper, qu’un pan considerable de la muséologie de la période post-moderne (20% en terme de volume d’activité ) est à peine reconnaissable, si on se réfère à la periode antérieure à la deuxième moitié du 20ème siècle. Le concept de MUSEE, dans deux champs antagonistes ou complémentaires, selon l’angle d’analyse, soit la muséologie entrée de plein pied dans les industries culturelles de l ‘ère des communications, et la muséologie (ou l’anti-musée) ayant adopté le parti-pris de l’intervention sociale, véhicules de systèmes idéologiques et organisationnels rompant radicalement avec un passé recent, se partageant entre la mondialisation globalisante et les aspirations du mouvement alter-mondialiste puissant dans la tradition associative. Tributaires d’une part des luttes libératrices (60/70), de la contestation des valeurs, d’autre part des technologies (80/90), de la globalisation (90. ), ces musólogies ( systéme binaire ) prennent la vedette à l’aide de changements irréversibles dans l’ordre des functions du musée.

How to avoid a double-dip recession in the eurozone. CEPS Commentary, 15 November 2012

This CEPS Commentary argues that the way in which the burden of adjustment to the imbalances in the eurozone is borne almost exclusively by the deficit countries in the periphery produces a deflationary bias in the region as a whole. Against the threat of double-dip recession, Paul De Grauwe asserts that the adjustment could be done differently and calls for implementation of a more symmetric macroeconomic policy that reduces the deflationary bias.

A double-Gerdien instrument for simultaneous bipolar air conductivity measurements on balloon platforms

A bipolar air conductivity instrument is described for use with a standard disposable meteorological radiosonde package. It is intended to provide electrical measurements at cloud boundaries, where the ratio of the bipolar air conductivities is affected by the presence of charged particles. The sensors are two identical Gerdien-type electrodes, which, through a voltage decay method, measure positive and negative air conductivities simultaneously. Voltage decay provides a thermally stable approach and a novel low current leakage electrometer switch is described which initiates the decay sequence. The radiosonde supplies power and telemetry, as well as measuring simultaneous meteorological data. A test flight using a tethered balloon determined positive (σ+) and negative (σ−) conductivities of σ+ = 2.77±0.2 fS m−1 and σ− = 2.82±0.2 fS m−1, respectively, at 400 m aloft, with σ+/σ− = 0.98±0.04.
