We Deliver: Overcoming Microform Collection Access Issues with Electronic Delivery.

This post-peer review, pre-copyedit version of the article submitted to IUPUI ScholarWorks as part of the OASIS Project.This presentation described the problems library users experienced trying to scan and save or print microform images at Valparaiso University. Complex, difficult to use equipment and software, unfamiliar formats, and file management difficulties interfered with a good experience for the user. Working to remove barriers to obtaining information, Weare piloted a project for library staff to scan and deliver electronically to users content from the microform collection. Not only did the process work, but the project proved that staff could successfully provide such a service

Student Impressions of Syllabus Design: Engaging Versus Contractual Syllabus

This study compared student impressions of a text-rich contractual syllabus to a graphic-rich engaging syllabus. Students enrolled in sections of an undergraduate introductory nutrition course viewed either a contractual or engaging syllabus and completed a survey regarding their perceptions of the course and instructor. Students perceived both types of syllabus positively, yet the engaging syllabus was judged to be more visually appealing and comprehensive. More importantly, it motivated more interest in the class and instructor than the contractual syllabus. Using an engaging syllabus may benefit instructors who seek to gain more favorable initial course perceptions by students.

A Nonce-Based Protocol For Multiple Authentications

The Kerberos authentication service, a part of MIT's Project Athena, is based on the Needham and Schroeder protocol. Timestamps depending on reliable synchronized clocks are used to guarantee the freshness of messages. As an improvement, we present a nonce-based protocol offering the same features as Kerberos. We generate a ticket in an initial message exchange which includes a generalized timestamp. Checking this generalized timestamp is left to the principal who created it. Consequently we do not need synchronized clocks. Our protocol has the property of using a minimal number of messages to establish an authenticated session key. 1 Introduction In computer networks and distributed computing systems a mechanism is needed to provide secure communication. To trust the identity of each other, two principals must run a procedure resulting in mutual authentication. Key distribution protocols establish secret authenticated session keys using conventional cryptography, also called symmetri..
