The Academic Ethics Of Students In Principles Of Economics

Questionnaires on academic ethics were completed by 115 students enrolled in principles of economics at a state university.  Ninety-seven percent admitted to having engaged in at least 1 of 16 academic practices while a university student considered unethical in the literature.  Levels of participation in specific practices ranged from 20% to 88% and were unrelated to student characteristics.  Students participated more in practices they rated less unethical.  Primary reasons for participation were that students wanted high grades and did not use available time to study.  Effects of academic dishonesty on institutions and ways of limiting dishonest behavior are discussed

A Conservative Finite Difference Scheme for Poisson-Nernst-Planck Equations

A macroscopic model to describe the dynamics of ion transport in ion channels is the Poisson-Nernst-Planck(PNP) equations. In this paper, we develop a finite-difference method for solving PNP equations, which is second-order accurate in both space and time. We use the physical parameters specifically suited toward the modelling of ion channels. We present a simple iterative scheme to solve the system of nonlinear equations resulting from discretizing the equations implicitly in time, which is demonstrated to converge in a few iterations. We place emphasis on ensuring numerical methods to have the same physical properties that the PNP equations themselves also possess, namely conservation of total ions and correct rates of energy dissipation. We describe in detail an approach to derive a finite-difference method that preserves the total concentration of ions exactly in time. Further, we illustrate that, using realistic values of the physical parameters, the conservation property is critical in obtaining correct numerical solutions over long time scales

Automatic Recognition of Light Microscope Pollen Images

This paper is a progress report on a project aimed at the realization of a low-cost, automatic, trainable system "AutoStage" for recognition and counting of pollen. Previous work on image feature selection and classification has been extended by design and integration of an XY stage to allow slides to be scanned, an auto focus system, and segmentation software. The results of a series of classification tests are reported, and verified by comparison with classification performance by expert palynologists. A number of technical issues are addressed, including pollen slide preparation and slide sampling protocols

From Course Reserves . . . to Course Reversed? The Library’s Changing Role in Providing Textbook Content

Academic libraries have always thought of “content” as their domain on campus. Yet beyond the course reserve desk, libraries have traditionally played a relatively small role on campus for the most common form of content in higher education, textbooks. Today, everything about textbooks and other course content is changing quickly. Spiraling costs have made textbooks a political issue in some states, while at the same time traditional textbook publishers experience economic pressures both from the growth of the used and rental markets and from new technological demands from the professors who assign their online books as well as from the students who use them. Librarians have begun to take notice, reversing course on the traditional library view of textbooks. A number of libraries are looking for more affordable ways for students to access textbooks. Many are leveraging open educational resources (OER) as alternatives to expensive, commercially-published textbooks. Other libraries have themselves become textbook publishers. This changed course has led librarians sometimes into new alliances and sometimes into degrees of conflict with other organizations, such as bookstores, commercial publishers, university presses, and aggregators

Controlling runoff and erosion at urban construction sites (2003)

This publication discusses typical practices to reduce erosion an dretain sediment on construction sites. Erosion- and sediment-control structures should be installed and maintained in accordance with local jurisdictions, manufacturers' specifications or engineering drawings

Recording of heritage buildings: from measured drawing to 3D laser scanning

This entry is a transcription of the opening keynote for the two-day international, peer reviewed conference held at the Bartlett School of Architecture, UCL on November 10-11 2016. It was simultaneously published in the book, "Drawing Futures - Speculations in Contemporary Drawing for Art and Architecture", edited by Laura Allen and Luke Caspar Pearson. It outlines my 30 years of speculative architectural drawing
