"You did a great job building that!" Links between parent-child prosocial talk and spatial language.

We investigated the extent to which parents' prosocial talk and negations relate to the quantity and diversity of parents' spatial language production. We also examined similar associations among children. Participants included 51 children of ages 4-7 years and their parents recruited from South Florida.

Science and agriculture: promoting beneficial symbiosis.

While fundamental research into key mechanisms and interactions is important, the practical investigations that scientists also undertake have additional considerations, since the results are applicable in the real world but need disseminating in a way that reaches the intended audience. Worldwide, rapid population growth produces multiple pressures on land, meaning agriculture must become more efficient and productive. Other pressures on farmers are also increasing: to meet environmental quality standards, to follow legislation about application of chemical products, to remain financially viable against uncertain markets, and more.

Assessment of Welfare in Zoo Animals: Towards Optimum Quality of Life.

Zoos are required to maintain a high standard of animal welfare, and this can be assessed using a combination of resource-based and animal-based indices usually divided into behavioural indicators, physiological indicators and clinical/pathological signs. Modern animal welfare assessments should aim to encompass positive affective states and the indicators that are useful in assessing these are discussed. When developing factors to be scored for each species, there is huge variability in the available information about the natural biology for some zoo species and even less information concerning those animals in captivity.

Iodine binding to humic acid.

The rate of reactions between humic acid (HA) and iodide (I(-)) and iodate (IO3(-)) have been investigated in suspensions spiked with (129)I at concentrations of 22, 44 and 88 μg L(-1) and stored at 10 °C. Changes in the speciation of (129)I(-), (129)IO3(-) and mixed ((129)I(-) + (129)IO3(-)) spikes were monitored over 77 days using liquid chromatography inductively coupled plasma mass spectrometry (LC-ICP-MS). In suspensions spiked with (129)I(-) 25% of the added I(-) was transformed into organic iodine (Org-(129)I) within 77 days and there was no evidence of (129)IO3(-) formation.
