In a time of hyperpolarization and hyper partisanship, preparing students to deliberate about their differences becomes even more important. In this interview, Diana Hess, dean of the School of Education at the University of Wisconsin-Madison and co-author of The Political Classroom, describes the challenge of ensuring that students have access to multiple and competing viewpoints about issues of public importance. In her research with co-author Paula McAvoy, Hess said she learned that students value hearing their teachers’ viewpoints as long as teachers aren’t pressing those views on students but that hearing a teacher’s viewpoint didn’t often change a student’s own opinion.

The High Voltage Electron Microscope Laboratory at the University of Wisconsin has been in operation a little over one year. I would like to give a progress report about our experience with this new technique. The achievement of good resolution with thick specimens has been mainly exploited so far. A cold stage which will allow us to look at frozen specimens and a hydration stage are now being installed in our microscope. This will soon make it possible to study undehydrated specimens, a particularly exciting application of the high voltage microscope.Some of the problems studied at the Madison facility are: Structure of kinetoplast and flagella in trypanosomes (J. Paulin, U. of Georgia); growth cones of nerve fibers (R. Hannah, U. of Georgia Medical School); spiny dendrites in cerebellum of mouse (Scott and Guillery, Anatomy, U. of Wis.); spindle of baker's yeast (Joan Peterson, Madison) spindle of Haemanthus (A. Bajer, U. of Oregon, Eugene) chromosome structure (Hans Ris, U. of Wisconsin, Madison). Dr. Paulin and Dr. Hanna are reporting their work separately at this meeting and I shall therefore not discuss it here.

Ustilago hordei and Ustilago violacea are yeast-like basidiomycete pathogens ofHordeum vulgare and Silene alba respectively. The mating type system in both species of Ustilago is bipolar, with alleles, A,a, (U.hordei) and a1, a2 (U.violacea) at a single locus. Haploid sporidia maintain the asexual phase by budding, while the sexual phase is initiated by conjugation tube formation between the mating types during budding and conjugation.For observation of budding, sporidia were prepared by culturing the four types on YEG (yeast extract glucose) broth for 24 hours. After centrifugation at 5000g cells were either left unmated or mated in a1/a2,A/a combinations. The sporidia were then mixed 1:1 with 4% agar and the resulting 1mm cubes fixed in 8% gluteraldehyde and post fixed in osmium tetroxide. After dehydration and embedding cubes were thin sectioned with a LKB ultratome and photographed in a Zeiss 9s transmission electron microscope or in an AE1 electron microscope of MK11 1MEV at the High Voltage Electron Microscopy Center of the University of Wisconsin-Madison.

In order to codify the political and partisan activity in Iraq, after a difficult labor, the Political Parties Law No. (36) for the year 2015 started and this is positive because it is not normal for the political parties and forces in Iraq to continue without a legal framework. Article (24) / paragraph (5) of the law requires that the party and its members commit themselves to the following: (To preserve the neutrality of the public office and public institutions and not to exploit it for the gains of a party or political organization). This is considered because it is illegal to exploit State institutions for partisan purposes . It is a moral duty before the politician not to exploit the political parties or some of its members or those who try to speak on their behalf directly or indirectly to achieve partisan gains. Or personality against other personalities and parties at the expense of the university entity.
