Effects of intertrial interval and exteroceptive feedback duration on discriminative avoidance acquisition in the gerbil

A series of studies of shuttlebox-avoidance learning in the gerbil evaluated the efficacy of an exteroceptive feedback stimulus (FS). Experiment 1 assessed the relative effectiveness of a FS at 30- and 90-sec intertriai intervals (ITIs), and found that the FS and warning signal termination contingencies were additive sources of avoidance reinforcement; i.e., they produced “supernormal acquisition” at the short ITI, but not at the 90-sec ITI. The effectiveness of a FS at the 30-sec ITI was further explored in Experiments 2 and 3, in which FS duration was varied in delayed and trace avoidance conditioning, respectively. In both studies, a FS facilitated acquisition but FS duration was not a critical determinant of performance. These results were interpreted in terms of an expectancy account of the informational value of a FS, and the problem of experimentally distinguishing between cognitive and inhibition-of-fear accounts of avoidance learning was discussed.     

Developing of methodologic tools for planning and managing library services: 3. Standardized inventories of library services

A standardized procedure was developed for eliciting those details of a library's service policies that are important to its users and for recording the data by checking appropriate categories on a form. This inventory procedure covers the entire spectrum of user services and accommodates a wide range of policies. The inventory was originally designed for use by trained interviewers in largescale surveys of academic medical libraries. However, it is also suitable for other kinds of libraries, and the Interview Guide and Checklist can be used for a self-survey by library staff. In addition to survey use, the inventory has a variety of educational, administrative, managerial, and research applications. A method for weighting the categorical inventory data to reflect the relative desirability of different policies makes it possible to calculate scores indicating how a library's policies compare with those of an "optimal" library. An analogous inventory of the services a library provides to other libraries was developed for surveying major backup resources in the medical library system.     

An Analysis of Four Institutional Strategies for Staff Development

This paper describes four different approaches through which an institution can provide a programme for academic staff training and development. The advantages and disadvantages of each approach are analysed with the help of a recently developed theory which seeks to explain why some innovations are successful while others fail. This analysis may contribute towards the development of institutional strategies to ensure the survival—if not the revival—of staff development in universities in the United Kingdom.     

Effects of Individualized Instruction on Control Expectancy: A Field Test

Abstract

This study was conducted in order to determine whether or not one semester of individualized instruction is enough time to create in students an increased sense of being able to control payoffs in life and to lead students to develop a more realistic appraisal of their ability to control payoffs in an academic environment. Paradoxically, the converse may occur. When first confronted with a success-oriented instructional process and opportunities for self-pacing, students with failure histories may become more external, anxious, or uncertain. In order to examine these notions, a sample of 126 educationally deficient students who were beginning their first semester of study in a community college were selected from 18 different sections of math, English, and history and tested twice—once at the beginning of the term and again late in the term just prior to finals.     

UCF Library Express: Planning a Faculty Delivery Service

As it becomes increasingly difficult to demonstrate the worth of the library to the academic community, gate counts and usage statistics are no longer enough. Showing the impact the library has on the community requires planning new services with outcome measurement from the start. This article outlines a project plan for launching a faculty book delivery service at the University of Central Florida's John C. Hitt Library using Rhea Rubin's (2006) Outcome Measurement model. The article reviews the relevant literature, analyzes the current internal and external climate in which the service will be implemented, discusses the logistical aspects of the service such as cost, delivery method, and staffing, and concludes by determining the goals and outcomes of the service based on these factors. This article is the first in a series of three articles that together make up an entire project planning and management document, including planning, marketing, and assessing the service. The plan in its entirety provides an example of how to apply the Outcome Measurement model in an academic library setting.
