Improving Traffic Safety Culture in Iowa – Phase II, July 2013

Phase II of Improving Traffic Safety Culture in Iowa focuses on producing actions that will improve the traffic safety culture across the state, and involves collaboration among the three large public universities in Iowa: Iowa State University, University of Northern Iowa, and University of Iowa. More specifically, this second phase synthesizes the expert opinions solicited in Phase I with prevailing public views and/or opinions gathered from a follow-up survey on Iowa’s 2000 public opinion survey, which the University of Northern Iowa, Center for Social and Behavioral Research, administered. More recent data on the opinions of Iowans and of people nationally contrasted with past data will help better define the public’s position on top safety culture issues. This, in turn, will provide a better basis for developing actionable, fundable, and ultimately successful strategies that will make a tangible difference in improving traffic safety in Iowa.

Comparison of the proliferative activity of neuroblasts from chick embryo cerebral hemispheres of different ages in culture.

Dissociated cerebral hemisphere cells from 4- to 7-day-old chick embryos were cultured either on a collagen or a polylysine substrate in a serum-containing medium. Neurons were characterized by the demonstration of acetylcholinesterase, the presence of D2/N-CAM glycoprotein and neurofilament proteins. The proliferation of neuronal precursor cells was shown by morphological observations, autoradiographic analysis and measurements of [3H]-thymidine incorporation. Neuronal precursors derived from the 6-day-old embryos showed the highest proliferative activity. Neuroblast proliferation was found to be dependent on the culture substrates (i.e. polylysine or collagen), which yielded either isolated cells or cell aggregates, and the latter favored the mitogenic effect.

Direct in vitro comparison of six three-dimensional positive contrast methods for susceptibility marker imaging.

PURPOSE: To compare different techniques for positive contrast imaging of susceptibility markers with MRI for three-dimensional visualization. As several different techniques have been reported, the choice of the suitable method depends on its properties with regard to the amount of positive contrast and the desired background suppression, as well as other imaging constraints needed for a specific application. MATERIALS AND METHODS: Six different positive contrast techniques are investigated for their ability to image at 3 Tesla a single susceptibility marker in vitro. The white marker method (WM), susceptibility gradient mapping (SGM), inversion recovery with on-resonant water suppression (IRON), frequency selective excitation (FSX), fast low flip-angle positive contrast SSFP (FLAPS), and iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) were implemented and investigated. RESULTS: The different methods were compared with respect to the volume of positive contrast, the product of volume and signal intensity, imaging time, and the level of background suppression. Quantitative results are provided, and strengths and weaknesses of the different approaches are discussed. CONCLUSION: The appropriate choice of positive contrast imaging technique depends on the desired level of background suppression, acquisition speed, and robustness against artifacts, for which in vitro comparative data are now available.

The four- vs. alternative six-factor structure of the French WISC-IV: Comparison using confirmatory factor analyses

Exploratory and confirmatory factor analyses reported in the French technical manual of the WISC-IV provides evidence supporting a structure with four indices: Verbal Comprehension (VCI), Perceptual Reasoning (PRI), Working Memory (WMI), and Processing Speed (PSI). Although the WISC-IV is more attuned to contemporary theory, it is still not in total accordance with the dominant theory: the Cattell-Horn-Carroll (CHC) theory of cognitive ability. This study was designed to determine whether the French WISC-IV is better described with the four-factor solution or whether an alternative model based on the CHC theory is more appropriate. The intercorrelations matrix reported in the French technical manual was submitted to confirmatory factor analysis. A comparison of competing models suggests that a model based on the CHC theory fits the data better than the current WISC-IV structure. It appears that the French WISC-IV in fact measures six factors: crystallized intelligence (Gc), fluid intelligence (Gf), short-term memory (Gsm), processing speed (Gs), quantitative knowledge (Gq), and visual processing (Gv). We recommend that clinicians interpret the subtests of the French WISC-IV in relation to this CHC model in addition to the four indices.

Pieces of Iowa’s Past, April 11, 2012

Pieces of Iowa’s Past, published by the Iowa State Capitol Tour Guides weekly during the legislative session, features historical facts about Iowa, the Capitol, and the early workings of state government. All historical publications are reproduced here with the actual spelling, punctuation, and grammar retained. April 11, 2012 THIS WEEK: Iowa State Capitol Mosaics BACKGROUND: Frederick Dielman Born in Germany in 1847, Frederick Dielman was an illustrator and figure painter. Dielman designed the six mosaic panels in the Iowa State Capitol along the east wall on the third floor. The mosaics were actually made in Venice, Italy, and shipped to the Capitol. The mosaics in the Capitol represent the three branches of government, education, defense, and charities.

January 23, 2013 THIS WEEK: Iowa’s Grasshopper Plague of 1873 BACKGROUND: Fifteen General Assembly The 15th General Assembly convened January 12 and adjourned March 19, 1874—a 67-day session. The Senate had six Democratic members, 34 Republican members, and 10 Independent members. The House of Representatives had six Democratic members, 50 Republican members, and 44 Independent members. There were a total of 150 legislators in Iowa. By 1874, the Capital had been relocated to Des Moines. The legislature had occupied the old Brick Capitol since 1858. Joseph Dysart was the Lieutenant Governor presiding in the Senate, and John Gear was Speaker of the House of Representatives. Iowa’s population at the 1870 federal census had grown to 1,194,020. Both House and Senate journals from the 15th Iowa General Assembly include several references to assisting the destitution brought on by the 1874 plague of grasshoppers in Northwestern Iowa. Senator Perkins, from the Special Committee appointed to inquire into the reports of destitution in the northwestern counties of Iowa, submitted the following report, in part: “We have examined such evidence as is attainable here, and made such inquiries of parties interested in affording temporary relief as were to be met, and are pieces satisfied in our own minds that the case is one of sufficient importance to command the attention of the State.”

The new culture of electronic publishing

Local conditions in the past often limited opportunities for scholarly exchange. But now these limits are gone and the global workplace has replaced them. It is important to react to these changes. Every academic department must now adopt new methods and rethink processes. Another is the intense national and international debate about open access to scholarly knowledge. The Open Access Initiative shows that a change is taking place in the communication process. This change is also important for service departments within research institutions. Libraries, computer centers and related units have to ask themselves how to react appropriately to the new conditions. What services must be changed or redeveloped, and in what quality and quantity should they be offered? This article focuses on changes in the scholarly publication process. It describes both technological changes and the changes needed in people's attitudes.
