A binaural sonar sensor for blind persons which models the bat sonar is described. System performance with field plots are presented along with signal analysis on objects forming targets. The distal spatial resolution is little more than one wavelength at the lowest frequency of 50 kHz. The operating bandwidth is 50 kHz producing the power to discriminate between objects. Distance and direction information is obtained over a field of view of 50 degrees within one frequency sweep. Blind persons have demonstrated mobility akin to sighted mobility. This knowledge is of value in designing robots.

Continuous Transmission Frequency Modulated (CTFM) ultrasonic sensors can be used to recognise plants. The echo from a plant is modelled as an acoustic density profile. Classification based on features extracted from the echo is more robust than classification based on the echo. Potential applications for this sensing system include landmark navigation and plant sensing for selective spraying of agricultural chemicals.

The news that Mr Antony Part is being transferred to another Ministry has caused some astonishment and concern in education and training circles. That his experience and knowledge can be spared at this stage for the sake of a routine reshuffle has surprised many people anxious for the development of further education in close concert with industrial training.

Since the first Volume of this Bibliography there has been an explosion of literature in all the main areas of business. The researcher and librarian have to be able to uncover specific articles devoted to certain topics. This Bibliography is designed to help. Volume III, in addition to the annotated list of articles as the two previous volumes, contains further features to help the reader. Each entry within has been indexed according to the Fifth Edition of the SCIMP/SCAMP Thesaurus and thus provides a full subject index to facilitate rapid information retrieval. Each article has its own unique number and this is used in both the subject and author index. The first Volume of the Bibliography covered seven journals published by MCB University Press. This Volume now indexes 25 journals, indicating the greater depth, coverage and expansion of the subject areas concerned.

This chapter examines staffing trends for Beta Alpha Psi (BAP) advisors over the past 20 years to document the degree of tenure- versus nontenure-track faculty involvement. We surveyed faculty advisors to determine how they are compensated for their BAP service. Our findings show a significant increase in the percentage of nontenure-track faculty filling the role of BAP advisor. Additionally, few advisors appear to receive pecuniary benefits for their service, and nearly one-third receive no reimbursement from their institutions for BAP-related expenses that they incur. We discuss the implications of these findings and their potential for limiting BAP's ability to execute future strategic initiatives.

Anthologies are an important contribution to literature from small presses. They are often collections with a theme used as a way of introducing new writers and new subjects. Small presses usually showcase the work of a wide range of writers from many cultures. The anthologies in this column reflect this tradition.
