Process versus product? : personal reflection and experimentation in task-based learning with the Hiroshima Teacher Trainees 2008
In my ten years of teaching, I’ve spent a
considerable amount of time devising the best
ways to teach linguistic elements, such as grammar
or pronunciation targets. Increasingly it seems to
me that this vantage could be fundamentally
flawed, as it focuses too heavily on product rather
than process. Here, I’m thinking of classes where
teachers strive to develop ‘authentic’ practice
situations that require the use of certain targets or
products. Their lesson plan focuses on the target
and the learners are encouraged to do the same
with practice activities. It begs the question,
wouldn’t it be more authentic to start with the
process? To start with the task and see what kind
of linguistic structures this engenders

Ca II TRIPLET SPECTROSCOPY OF SMALL MAGELLANIC CLOUD RED GIANTS. IV. ABUNDANCES FOR A LARGE SAMPLE OF FIELD STARS AND COMPARISON WITH THE CLUSTER SAMPLE
This paper represents a major step forward in the systematic and homogeneous study of Small Magellanic Cloud (SMC) star clusters and field stars carried out by applying the calcium triplet technique. We present in this work the radial velocity and metallicity of approximately 400 red giant stars in 15 SMC fields, with typical errors of about 7 km s-1 and 0.16 dex, respectively. We added to this information our previously determined metallicity values for 29 clusters and approximately 350 field stars using the identical techniques. Using this enlarged sample, we analyze the metallicity distribution and gradient in this galaxy. We also compare the chemical properties of the clusters and of their surrounding fields. We find a number of surprising results. While the clusters, taken as a whole, show no strong evidence for a metallicity gradient (MG), the field stars exhibit a clear negative gradient in the inner region of the SMC, consistent with the recent results of Dobbie et al. For distances to the center of the galaxy less than 4\ub0, field stars show a considerably smaller metallicity dispersion than that of the clusters. However, in the external SMC regions, clusters and field stars exhibit similar metallicity dispersions. Moreover, in the inner region of the SMC, clusters appear to be concentrated in two groups: one more metal-poor and another more metal-rich than field stars. Individually considered, neither cluster group presents an MG. Most surprisingly, the MG for both stellar populations (clusters and field stars) appears to reverse sign in the outer regions of the SMC. The difference between the cluster metallicity and the mean metallicity of the surrounding field stars turns out to be a strong function of the cluster metallicity. These results could be indicating different chemical evolution histories for these two SMC stellar populations. They could also indicate variations in the chemical behavior of the SMC in its internal and external regions

Common Root and Crown Rot Diseases of Wheat in South Dakota
Disease Impact Root and crown rotting diseases are among the most common and destructive diseases of wheat in South Dakota. They are present in every growing season and are estimated to cause as much as 3-4% crop losses in an average year. Losses may be greater in years with environmental conditions favoring specific root or crown diseases
In the hands of the user: a framework for the analysis of online engagement with digital heritage collections
Within a context of recent and rapid transformation in authorship and participation practices
on the Internet, this thesis explores the implications of an emerging digital culture for
heritage institutions, such as museums and archives. Combining insights from internet,
education and museum theory it explores different experiences of participation and meaning
making around digital heritage collections opened to public engagement and contribution. In
particular, the investigation analyses and contrasts the online activities of the Royal
Commission on the Ancient and Historical Monuments of Scotland (RCAHMS), partner in
the research, with alternative approaches. The thesis applies ethnographic research methods
to investigate embodied and virtual settings. Based on the empirical findings, it identifies
different theoretical models of online engagement with heritage content. It then extrapolates
from these models a conceptual framework that could be used by heritage institutions to
analyse and re-assess their online practices, intellectual positioning and strategic ambitions
in the context of the paradigm shift brought about by digitality
