title: Note on random raindrops and sampling error

authors: Bardsley, W. Earl

abstract: A number of variables of interest in precipitation studies can be interpreted as sums of random numbers of random variables, where the summed quantity is a power transformation of raindrop diameter. Included in this category are raingauge measurements and radar reflectivity. A general expression is given for the coefficient of variation of such variables when the number of terms per sum and the transformed variable follow any specified probability distribution. Some simple expressions are obtained for the special case of an exponential distribution of raindrop diameters.

title: The equilibrium model for the effect of temperature on enzymes: Insights and implications

authors: Weinberg, Cristina S.

subjects: Equilibrium Model

abstract: A new, experimentally-validated “Equilibrium Model” describes the effect of temperature on enzymes, and provides a new mechanism for the reversible loss of enzyme activity with temperature. It incorporates two new, fundamental parameters that allow a complete description of the effect of temperature on enzyme activity: ΔHeq and Teq. ΔHeq emerges as an intrinsic and quantitative measure of enzyme eurythermal adaptation, while Teq, the equilibrium temperature, has fundamental and technological significance for our understanding of the effect of temperature on enzymatic reactions. For biotechnological purposes, these parameters need to be considered when enzymes are applied or engineered for activity at high temperatures.

title: Culture, for and against: patterns of "Culturespeak" in New Zealand

authors: Goldsmith, Michael

subjects: multiculturalism

abstract: Culture is invoked not only as a means of justifying redress for discrimination or historical injustice, but also as a standard of accountability by which the upholding of rights (or their suppression) can be measured. Rather than assume conceptual coherence regarding the notion of culture that such applications appear to share, it is proposed to analyse them as terms within a broad and open-ended field of 'culturespeak', a concept generally ascribed to Ulf Hannerz.
