The United States and Europe: interdependence and cooperation. Speech by George Thomson. Grinnell, Iowa, 6 April 1976
Speech [on Italy and structural funds spending] by Rt. Hon. George Thomson [EC Commissioner for regional policy] to the Centre international de formation europeenne. Venice, 11 October 1974
The more things change, the more they remain the same
February in the Midwest can be rigorous. When wind-chill factors in the minus forties are added to the concerns for enrollment, budget and employment, it is not unusual to recall such notable quotes as winter of discontent, and “be not a summer soldier and a sunshine patriot, and these are the times that try men\u27s souls
Dedication to Dr. Dwight Bensend
To write about Dwight Bensend is not an easy thing for me to do. A letter of thanks to him for all of his kindnesses through the last 30-odd years-yes; a memorial statement yes; an analysis of his manner of living-yes; but to select those few hundred words that explain to young people how he came to be so much revered and how those facets of his life that have come to be so admired might be copied, I find almost beyond me
Enzyme variation at morphological boundaries in Maniola and related genera (Lepidoptera: Nymphalidae: Satyrinae)
The evolutionary biology of 14 species of Maniolini (Nymphalidae:
Satyrinae) was studied.
Electrophoretic analysis of 35 enzyme loci identified a larger number
of alleles than an1 levels of polymorphism similar to those found in
other Lepidoptera.
In Maniola jurtina, some populations exhibited a massive heterozygote
deficit and sex associated allele frequency differentiation at the
GOT-l locus. Allele frequencies in pre- and post-aestivation jurtina
from southern Europe were significantly different. At some loci, significant
annual differences in allele frequencies were noted.
A significant correlation between geographic and genetic distance in
allele frequencies was observed, but no correlation was detected
between heterozygosity and land area in insular populations.
Cluster analysis and nonmetric multidimensional scaling per~ormed on
electrophoretic data from populations of Maniola jurtina revealed a
dichotomy between 'Eastern' and 'Western' subspecies groups. The
analysis of Manioline species fitted existing taxonomies.
Genetic differences between Maniola species were much smaller than
those between Pyronia and Hyponephele species.
Ultrastructural studies of the Maniola Jullien organs revealed a
species-specific tooth pattern on the inner surfaces. It is suggested
that these structures may be sound production mechanisms of great
evolutionary significance to the species.
Maniolini ova were studied and it is suggested that their form and
chorionic sculpturing owe much to selection induced by oviposition
strategy.
Chaetotaxy of first instar larvae was undertaken and morphometric
analysis of setal lengths was found to be useful, but not unambiguous.
Multivariate analysis of chaetotaxy data showed a significant correlation
with electrophoretic data.

The evolution and zoogeography of Maniola is discussed. It is suggested
that disjunction, founder effect, rapid post-glacial colonisation
and bottlenecking have played a major roles in effecting rapid
speciation. It is further suggested that all Maniola species are very
recent, perhaps having evolved within the last 50,000 years, and some
species almost certainly have evolved in postglacial times
State of the Department Address “From the Northwest Corner
Thanks to planning put forth by department heads and architects 15 years gone, my desk looks out on a panorama from Old Botany to the southwest around to Lush auditorium and Animal science to the northeast. In the arc in between I see views that have been familiar to me ever since 1939 when I first saw Iowa State College as a green farm boy from Pecatonica. within view are Home Ec., where you can still buy cherry pies at VEISHEA and where the only girls we ever got to know had their classes; the big glacial erratic with the fine granite dikes in it that was brought onto campus in memory of Doc Gwynne because he always took students out in the woods to see it; the riding horse paddock by the railroad tracks which, even now, isn\u27t far from the old ROTC cavalry horse bull Pen where we all learned to ride, Artillery style, and found that after a hot afternoon with the horses no civilian would sit near us

COME on, come on! Speed it up, Dope! How\u27m I ever gonna make a musician outa you? My brother\u27s voice came crackling down the stairs and, as usual, ruffled my temper the wrong way..
