This study proposes DC-ROLL, a new approach to concurrency control in a distributed environment based on the Request Order Linked List (ROLL) [P91] and the Datacycle architecture [H+87]. DC-ROLL allows for more flexibility in levels of concurrency and avoids certain performance bottlenecks of the traditional two-phase locking. Unlike the original Datacycle… (More)
⎯ The computing infrastructure has, and continues, to endure rapid change as hardware, software, and communication infuse society and as the user community gains experience and sophistication. To meet these changing demands the educational computing community has experienced something of a metamorphosis, starting from a fundamentally computer science… (More)
In the Department of Computer and Information Sciences at Indiana University, course evaluations are used as an important instrument for assessing teaching effectiveness and maintaining the quality of our academic programs. At the end of each semester students are given the opportunity to evaluate their courses and the results are collected and analyzed by… (More)
Software development is a fast-changing area. New methods and new technologies emerge all the time. As a result, the education of software engineering is generally considered not to be keeping pace with the development of software engineering in industry. Given the limited resources in academia, it is unre-alistic to purchase all the latest software tools… (More)
There is ample evidence of positive impact of active learning on student learning, attitudes, critical thinking, and retention. The traditional lecture-style classrooms are not suitable for group interaction or activities. Having an appropriate classroom with proper technology to support active learning is essential. In order to foster easier group… (More)
As computer science continues to move toward a more pragmatic market driven discipline, some of the traditional core topics in computing have become less popular. At-risk topics include compilers, file organizations, and operating systems. Viewed collectively, it appears that courses that either deal with the internal working of computers or courses that… (More)
Computing as a student major-of-choice is undergoing a serious transformation. Perceptions of globalization and outsourcing appear to influence career choice as outlined by the ACM Job Migration Task Force. As a result, students must be prepared to work in domain specific environments with competence and agility early in their careers. Indiana University… (More)
