This article will detail the results of a survey distributed within the United States of America to professionals working in academic, public, school/media, and special libraries that asked respondents to rate their daily copyright and intellectual property knowledge needs vs. their actual knowledge and education in this area. The results were then compared with an analysis of course content in current ALA accredited LIS programs in the U.S. gathered from online course descriptions to determine whether there is evidence pointing to a need to alter the curriculum of LIS programs to better prepare graduates for the copyright and intellectual property demands they will face on the job. The combined data will inform Library Science colleges and educators as to whether an instruction deficit exists in their current curricula and will give these colleges and educators data to support the development of new programs.
Dose profiles produced by wedge filters in the non-wedged direction can exhibit a 7% or greater dose reduction at the outer ends of the field compared with open field profiles. However, many planning systems use open field profiles to model wedged dose distributions. In the present work, wedges have been modified to reproduce open field profile shapes. This modification involved removing varying thicknesses of the wedge using a simple milling machine. The wedge thickness was calculated using the assumption that dose is proportional to primary collision kerma. The discrepancies in dose between wedged field and open field profile shapes of up to 7% were reduced to less than 3% with the modifications, even for varying depths and off-axis distances. The necessary measurements are simple to perform, and hence this technique could be applied to improve wedged field dose distributions in other radiotherapy departments.
Library and information science literature tells a story of the recent surge in creation the copyright librarian positions in academic libraries from identification of need to construction of job responsibilities and position requirements. This article seeks to continue the story by identifying what information materials and services the librarians responsible for providing copyright assistance have created at their libraries, and how those services are delivered to their institutions. An examination of 115 library websites is employed to identify topics and foci within copyright services with the goal of establishing commonalities of service among U.S. research one libraries that can be used to inform new service development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
