Assessing Cultural and Ecological Variation in Ethnobiological Research: The Importance of Gender
Contending that a significant portion of current ethnobiological research continues to overlook cultural variation in traditional ecological knowledge (TEK) and practice, this paper explores the potential impacts of gender-imbalanced research on data collection, hypothesis testing, and the formulation and application of ethnobiological inventories and theories. A multidisciplinary review of over 220 studies addresses commonly held stereotypes underlying gender-imbalanced field research and demonstrates the need for more inclusive, finely-tuned studies which disaggregate indigenous knowledge and practice by gender. The paper outlines factors underlying gender-based spatial and temporal variation in ecosystem exposure and traditional ecological knowledge in rural societies worldwide, and discusses how these factors contribute to gender differences in wild food harvesting, biodiversity and agrobiodiversity maintenance, natural resource management, and the transmission and conservation of sacred and secular customs. The review concludes with suggestions for designing and implementing more inclusive research
Results from thinning experiments in 2002 and 2003
In 2002 an experiment about thinning blossoms of the apple variety 'Pinova' lime sulfur (in 2002 45
% thinning) and sodium salt (21 % thinning) showed good effects, the number of blossom-clusters
in 2003 was very high in the lime sulfur parcels. Results from extracts of Hericium erinaceum in
2003 have to be replicated again, the number of applications must be increased
A new development cycle of the Statistical Toolkit
The Statistical Toolkit is an open source system specialized in the
statistical comparison of distributions. It addresses requirements common to
different experimental domains, such as simulation validation (e.g. comparison
of experimental and simulated distributions), regression testing in the course
of the software development process, and detector performance monitoring.
Various sets of statistical tests have been added to the existing collection to
deal with the one sample problem (i.e. the comparison of a data distribution to
a function, including tests for normality, categorical analysis and the
estimate of randomness). Improved algorithms and software design contribute to
the robustness of the results. A simple user layer dealing with primitive data
types facilitates the use of the toolkit both in standalone analyses and in
large scale experiments.Comment: To be published in the Proc. of CHEP (Computing in High Energy

Black hole initial data on hyperboloidal slices
We generalize Bowen-York black hole initial data to hyperboloidal constant
mean curvature slices which extend to future null infinity. We solve this
initial value problem numerically for several cases, including unequal mass
binary black holes with spins and boosts. The singularity at null infinity in
the Hamiltonian constraint associated with a constant mean curvature
hypersurface does not pose any particular difficulties. The inner boundaries of
our slices are minimal surfaces. Trumpet configurations are explored both
analytically and numerically.Comment: version for publication in Phys. Rev.
