From Treading Water to Smooth Sailing: Mentoring for New Academic Librarians

The two authors were paired as part of a formal mentoring program for orientation and to prepare for eventual promotion and tenure. One author has over twenty-five years’ experience on campus, and the other author has completed one year in her current position. During that first year, various themes emerged to remind both librarians that the more things change, the more they remain the same. As the mentoring experience evolved, it became difficult to distinguish the mentor from the mentee because both librarians understood that discussing common issues was mutually beneficial.     

A linguistic analysis of spoken and written language

Samples of spoken and written language obtained from professors of speech who had written extensively were analyzed for the frequency of the four major parts of speech and for two grammatical ratios which measure degree of qualification. Five of the six measures employed differentiated the two forms of discourse at statistically significant levels.     

Enhancement of conditioned inhibition via an extinction treatment

Rats were used in a conditioned-suppression paradigm to determine whether an extinction treatment would enhance a moderately developed conditioned inhibitor (CS?). To dissipate unconditioned suppression to the training stimuli, the subjects were first habituated to the stimuli and then given Pavlovian conditioned-inhibition (CI) training involving reinforced presentations of a clicker and nonreinforced compound presentations of that stimulus and the intended CS?, either a light or a tone. Thereafter, experimental subjects received presentations of their CS? by itself, whereas controls received no further training. Following the occurrence and loss of conditioned suppression to the CS? in the extinction phase, summation and retardation tests showed enhanced CI for the experimental subjects relative to both the controls and their own earlier levels of inhibitory performance. In fact, the enhanced inhibition for the experimental subjects approximated that shown by a comparison group for which the CS? had been strongly developed as an inhibitor. These findings suggest that an excitatory representation is associated with the CS? early in CI training, and that subsequent presentations of the CS? by itself strengthen its inhibitory effect by allowing it to be nonreinforced in the presence of that representation.     

Reading achievement of Rhode Island compensatory education students: A school effects study

This study investigated the unique and common contributions of four sets of predictor variables: (1) background, (2) mental ability, (3) program, and (4) parental involvement, to the variance in reading achievement scores—vocabulary and comprehension—for Title I students enrolled in Rhode Island remedial reading programs. The vocabulary analysis indicated that the four sets accounted uniquely for 7, 13, 9, and 9% of the variance, respectively. The comprehension analysis indicated that the four sets accounted for 7, 25, 5, and 4% of the variance, respectively. Joint contributions are also presented.     

Positive and negative transfer of conditioned aversive stimuli to a conditioned appetitive excitor as a function of aversive US intensity

Rats were given Pavlovian aversive (Av) conditioning in which a weak (0.5-sec, 0.7-mA) or a strong (0.5-sec, 1.4-mA) footshock unconditioned stimulus (US) was presented alone or in a positive, zero, or negative correlation with a flashing-light conditioned stimulus (AvCS+, AvCSo, or AvCS?, respectively). Thereafter, the subjects received Pavlovian appetitive (Ap) conditioning in which the flashing-light CS was positively correlated in a forward order with the delivery of a food US. As anticipated, for subjects that had been trained with the strong shock US, the AvCS+ retarded and the AvCS? facilitated Ap conditioning relative to both the AvCSo and the novel-CS treatments, which did not differ in effect. However, the exact opposite prevailed for the AvCS+ and AvCS? subjects that had been trained with the weak shock US. On the basis of these and other data, we propose an “ABC” model of transfer that stresses the importance of affective, behavioral, and cognitive factors in accounting for the divergent results that are obtained in both Av-to-Ap and Ap-to-Av transfer paradigms.
