Polonium-210 and Lead-210 activities measured on 17 water bottle profiles and 50 surface water samples during POLARSTERN cruise ARK-XXII/2

Polonium-210 and Lead-210 have been measured in the water column and on suspended particulate matter during the POLARSTERN cruise ARK-XXII/2. The data have been submitted to Pangaea following a Polonium-Lead intercalibration exercise organized by GEOTRACES, where the AWI lab results range within the data standard deviation from 10 participating labs. Polonium-210 and Lead-210 in the ocean can be used to identify the sources and sinks of suspended matter. In seawater, Polonium-210 (210Po) and Lead-210 (210Pb) are produced by stepwise radioactive decay of Uranium-238. 210Po (138 days half life) and 210Pb (22.3 years half life) have high affinities for suspended particles. Those radionuclides are present in dissolved form and adsorbed onto particles. Following adsorption onto particle surfaces, 210Po especially is transported into the interior of cells where it bonds to proteins. In this way, 210Po also accumulates in the food chain. 210Po is therefore considered to be a good tracer for POC, and traces particle export over a timescale of month. 210Pb (22.3 years half life) adsorbs preferably onto structural components of cells, biogenic silica and lithogenic particles, and is therefore a better tracer more rapidly sinking matter. Our goal during ARK XXII/2 was to trace pathways of particulate and dissolved matter leaving the Siberian Shelf. The pathways of particulate and dissolved matter will be followed by the combined use of 210Po and 234Th as a tracer pair (and perhaps 210Pb) for particle flux (Cai, P.; Rutgers van der Loeff, MM (2008) doi:10.1594/PANGAEA.708354). This information gathered from the water column will be complemented with the results of the 210Po-210Pb study in sea ice (Camara-Mor, P, Instituto de Ciencias del Mar-SCIC, Barcelona, Spain) to provide a more thorough picture of particle transport from the shelf to the open sea and from surface to depth.

Prevalencia y factores asociados al consumo de bebidas azucaradas en escolares de 9 a 17 años de Bogotá, Colombia: Estudio FUPRECOL

Objetivo: Determinar la prevalencia y los factores asociados al consumo de bebidas azucaradas en una población escolar de Bogotá, Colombia, pertenecientes al estudio FUPRECOL. Métodos: Estudio descriptivo y transversal, realizado en 8136 niños y adolescentes en edad escolar entre 9 y 17 años de Bogotá, Colombia. El peso, la estatura, el índice de masa corporal (IMC), la circunferencia de cintura y el porcentaje de grasa, se recogieron como marcadores antropométricos y de composición corporal. El consumo de bebidas azucaradas (bebidas carbonatadas, jugos ultra-procesados y/o Té), y los factores asociados (sexo, edad, obesidad abdominal, clasificación del IMC, grado de estudios de la madre/padre, y nivel nutricional por cuestionario “Krece plus”), se recogieron por encuesta estructurada. Se establecieron asociaciones mediante la construcción de modelos de regresión logística simple. Resultados: De la población general, el 58,4% eran mujeres. En función al sexo, los varones acusaron la mayor ingesta de “bebidas carbonatadas” con una frecuencia semanal y diaria de 70,9% y 21,0%, respectivamente, seguido de “jugos ultra- procesados” (64,4% semanal vs. 11,3% diario). En ambos sexos, la prevalencia de obesidad abdominal fue mayor en los escolares que respondieron consumir diariamente “bebidas carbonatadas” (23,3%), “jugos ultra-procesados” (13,2%) y “bebidas Té” (9,7%). La edad, el grado de educación de los padres y el nivel nutricional, se asociaron como factores predisponentes al consumo diario de “bebidas carbonatadas”. Conclusión: El consumo de bebidas azucaradas cambia por los factores analizados. Se recomiendan intervenciones integrales en las que estén involucrados los componentes nutricional y educativo entre los niños y adolescentes de Bogotá, Colombia.

Drawing the line : the legal status and treatment of the 17-year-old accused in Queensland

Seventeen year olds who come into contact with the police in Queensland are classified as adults and are not afforded the protections available under the Youth Justice Act 1992 (Qld) (YJA). As with any other adult, their offences are dealt with under a raft of legislative provisions including the Criminal Code 1889 (Qld) (the Code), the Police Powers and Responsibilities Act 2000 (Qld) (PPRA) and the Penalties and Sentences Act 1992 (Qld) (PSA). This article argues that this situation is unfair and contravenes international human rights agreements which Australia has ratified, in particular the United Nations Convention on the Rights of the Child (CROC). Article 1 of that Convention defines a child as a person under the age of 18. The youth offences legislation in Queensland only applies to those who have not yet turned 17. This article examines the effects of this anomaly in Queensland, focusing in particular on the pre-adjudication treatment of ‘17 year old adults’.

Queensland Environmental Practice Reporter 17(77) (2011/2012) Editorial

This issue begins with a paper by QUT masters student, Jenny Kortlaender, which considers the effectiveness of the United Nations Convention on Biological Diversity in addressing global biodiversity decline. This is followed by a paper by Fiona Leddy which critically analyses international shipping in Australian waters and the approach taken by Australia laws in addressing the risks posed by ship-based oil pollution. The third paper in this issue is by Adjunct Professor Hugh Lavery, Gina Lee and Carolyn S. Sandercoe. This paper considers the ecological principles to be followed in the sustainable design of large-scale marina developments. This paper highlights the differences between the practice of landscape ecology and the design of ecological landscapes.

Responsiveness of the Effective Consumer Scale (EC-17)

Objective. The Effective Consumer Scale (EC-17) comprises 17 items measuring the main skills and behaviors people need to effectively manage their healthcare. We tested the responsiveness of the EC-17. Methods. Participants, in 2 waves of a 6-week Arthritis Self-Management Program (ASMP) from Arthritis Ireland, received a questionnaire at the first and last week of the weekly ASMP. The questionnaire included the EC-17 and 10 other measures for arthritis. Deficits, mean change, and standard deviations were calculated at baseline and Week 6. The EC-17 scores were compared to the Arthritis Self-Efficacy (ASE) and Patient Activation Measure (PAM) scales. Results were presented at OMERACT 9. Results. There is some overlap between the EC-17 and the ASE and PAM; however, most items of greatest deficit in the EC-17 are not covered by those scales. In 327 participants representing both intervention waves (2006 and 2007), the EC-17 was more efficient than the ASE but less efficient than the PAM for detecting improvements after the ASMP, and was moderately correlated with the PAM. Conclusion. The EC-17 appears to measure different skills and attributes than the ASE and PAM. Discussions with participants at OMERACT 9 agreed that it is worthwhile to measure the skills and attributes of an effective consumer, and supported the development of an intervention (such as proposed online decision aids) that would include education in the categories in the EC-17.

The association between maternal infant feeding practices and child weight at 11-17 months in first-time Australian mothers

Introduction: Emerging evidence reveals that early feeding practices are associated with child food intake, eating behaviour and weight status. This cross-sectional analysis examined the association between maternal infant feeding practices/beliefs and child weight in Australian infants aged 11-17 months. Methods: Participants were 293 first-time mothers of healthy term infants (144 boys, mean age 14±1 months) enrolled in the NOURISH RCT. Mothers self-reported infant feeding practices and beliefs using the Infant Feeding Questionnaire (Baughcum, 2001). Anthropometric data were also measured at baseline (infants aged 4 months). Multiple regression analysis was used, adjusting for infant age, gender, birth weight, infant feeding mode (breast vs. formula), maternal perceptions of infant weight status, pre-pregnancy weight, weight concern, age and education. Results: The average child weight-for-age z-score (WAZ) was 0.62±0.83 (range:-1.56 to 2.94) and the mean change in WAZ (WAZ change) from 4 to 14 months was 0.62±0.69 (range:-1.50 to 2.76). Feeding practices/beliefs partly explained child WAZ (R2=0.28) and WAZ change (R2=0.13) in the adjusted models. While child weight status at 14 months was inversely associated with responsive feeding (e.g. baby feeds whenever she wants, feeding to stop baby being unsettled) (β=-0.104, p=0.06) and maternal concern about the child becoming underweight (β=-0.224, p<0.001), it was positively associated with mother’s concern about child overweight (β=0.197, p<0.05). Birth weight, infant’s age, maternal weight concern and perceiving her child as overweight were significant covariates. WAZ change was only significantly associated with responsive feeding (β=-0.147, p<0.05). Conclusion: Responsive feeding may be an important strategy to promote healthy child weight.
