A Note from the Guest Editor to Emily Dickinson: A Few Epistles from the World
Dear Miss Dickinson: I have often wondered what the results would have been if you had sent your letter to Ralph Waldo Emerson instead of Thomas Wentworth Higginson? But that is speculative history and that is not my intended purpose here. I come bringing you this packet of fourteen essays. They are letters to you from the world. These are not the only ones to result from the centennial of your passing. There is a wealth of other essays, critical books, as well as significant biographies which attest to your faith in your work and to your importance to the total fabric of American literature

Genotypic and phenotypic diversity differences of presumptive commensal and avian pathogenic E. coli
1. The objective of the experiment was to characterise the genotypic and phenotypic differences between presumptive commensal E. coli and avian pathogenic E. coli (APEC) of poultry.
2. DNA was extracted from 65 confirmed APEC E. coli from chicken, 100 presumptive commensal E. coli from healthy turkey and 35 from healthy chicken. Enterobacterial repetitive intergenic consensus PCR (ERIC-PCR) and virulence factors genotyping was performed to characterise genetic features.
3. Carbon source utilisation and antimicrobial susceptibility tests were performed to characterise phenotypic features of isolates.
4. The genetic divergence between E. coli strains tested by ERIC-PCR profiles and virulence associated genes showed a clear genetic separation between E. coli APEC and turkey E. coli strains.
5. The carbon utilisation profile of turkey isolates was different from chicken and APEC strains; whereas antimicrobial susceptibility was highest for turkey isolates (53%), and lowest for APEC strains (33.8%).
6. The study showed a significant negative correlation between utilisation of arabitol and adonitol with different virulence determinants tested, which suggests that the ability to utilise some uncommon carbon sources may be used to discriminate between presumptive commensal E. coli and APEC

An Undergraduate Information Security Program: More than a Curriculum
This paper describes the implementation of an information security program at a large Midwestern university. The initial work is briefly summarized and improvements that have occurred over time are described. Current activities and future plans are discussed. This paper offers insight and lessons learned for organizations that have or are planning to implement an information security program. Some key success factors for this program have been a faculty project champion, faculty dedication and tenacity, involvement with industry partners, alumni, and students, and continuous improvement
Structural phase transitions in the Ag2Nb4O11 – Na2Nb4O11 solid solution
The phase transitions between various structural modifications of the natrotantite-structured system
xAg2Nb4O11 – (1-x)Na2Nb4O11 have been investigated and a phase diagram constructed as a function
of temperature and composition. This shows three separate phase transition types: (1) paraelectric –
ferroelectric, (2) rhombohedral – monoclinic and (3) a phase transition within the ferroelectric
rhombohedral zone between space groups R3c and R3. The parent structure for the entire series has
space group R-3c. Compositions with x > 0.75 are rhombohedral at all temperatures whereas
compositions with x < 0.75 are all monoclinic at room temperature and below. At x = 0.75,
rhombohedral and monoclinic phases coexist with the phase boundary below room temperature being
virtually temperature-independent. The ferroelectric phase boundary extends into the monoclinic
phase field. No evidence was found for the R3–R3c phase boundary extending into the monoclinic
phase field and it is concluded that a triple point is formed
