Examines how assessment is constructed and understood, i.e., some of the conflicting subject positions writing instructors occupy when in the throes of grading. Suggests that "teacher selves" affect the act of grading, but so too do the subject positions of "student selves," namely, unconscious and/or superficial factors. (PA)

Designed to be used primarily as a reader for first and second graders, but also as a speller and vocabulary builder for any student who needs help in language arts mastery, this book combines phonics with the "Look and Say" methods to present a step-by-step learning guide. Following an introduction explaining the five-step procedure teachers can use to introduce new material to the student, the book presents initial consonant and consonant combination charts, along with indexes of illustrations and stories and notes on usage. The major portion of the book consists of 287 pages of succinct "stories" written in rhythmic prose intended to aid in the decoding process, as well as verbal exercises for pronunciation practice and vocabulary development. Two appendixes provide lists of spelling rules and beginning consonants. (NKA)

A grade one through two teacher describes how her class created and shared original hardcover books. Highlights include how to put the books together, a source for ordering blank books, handwritten vs. typed books, and a "literary luncheon" to share the books with families. (PEN)

Oxytetracycline-resistant (OT(r)) mesophilic aeromonads were recovered from untreated hospital effluent (72 isolates) and from fish farm hatchery tanks (91 isolates) at sites within the English Lake District, Cumbria, England. The transfer of OT(r) plasmids from these isolates was investigated. Using Escherichia coli J53-1 as a recipient, 11 isolates from the hospital site and 6 isolates from the fish farm site transferred OT(r) plasmids (designated pFBAOT1 to 17). Original isolates were identified using fatty acid methyl ester and fluorescent amplified fragment length polymorphism comparisons as either Aeromonas hydrophila HG3 (eight isolates), A. veronii b.v. sobria HG8 (six isolates), and A. caviae HGB5 (one isolate). One isolate remained unidentified, and one could not be assigned a taxonomic designation beyond the genus level. Plasmids pFBAOT1 to -17 were screened for the presence of the tetracycline resistance determinants Tel A to E and Tet G. Only determinant Tet A (10 plasmids) was detected in these plasmids, with 7 tet gene determinants remaining unclassified. In all cases, Tet A was located on a 5.5-kb EcoRI restriction fragment. Hybridization with inc-rep probes N, P, Q, W, and U showed pFBAOT3, -4, -5, -6, -7, -9, and -11, from the hospital environment, to be IncU plasmids. Further, restriction fragment length polymorphism (RFLP) analyses and DNA probing demonstrated that pFBAOT plasmids were closely related to IncU OT(r) plasmids pASOT, pASOT2, pASOT3, pRAS1 (originally isolated from A. salmonicida strains from fish farms in Scotland and Norway, respectively), and pIE420 (isolated from a German hospital E. coli strain). In addition, DNA analyses demonstrated that plasmids pRAS1 and pIE420 had identical RFLP profiles and that all fragments hybridized to each other. The presence of tetracycline resistance transposon Tn1721 in its entirety or in a truncated form in these plasmids was demonstrated. These results provided direct evidence that related tetrac
