Preference-Guided Register Assignment

Abstract. This paper deals with coalescing in SSA-based register allo-cation. Current coalescing techniques all require the interference graph to be built. This is generally considered to be too compile-time intensive for just-in-time compilation. In this paper, we present a biased coloring approach that gives results similar to standalone coalescers while signif-icantly reducing compile time.

Unrecognized Backscattering in Low Energy Beta Spectroscopy

We present studies on electron backscattering from the surface of plastic scintillator beta detectors. By using a setup of two detectors coaxial with a strong external magnetic field - one detector serving as primary detector, the other as veto-detector to detect backscattering - we investigate amount and spectrum of unrecognized backscattering, i.e. events where only one detector recorded a trigger signal. The implications are important for low energy particle physics experiments.Comment: 5 pages, 8 figures; v2: published NIM A versio

Experiences of taking students on business trips: with recommendations for organising successful business trips

They can be linked with classroom learning and teaching and can also provide opportunities for work- related assessment. This paper presents the outcome of a teaching and learning project that aimed to take a number of undergraduate and postgraduate business students from the University of Hertfordshire on a variety of operations-related business trips during the academic year 2009/2010. The organisation of these trips is described and they are evaluated by students. It is demonstrated that such trips take some time to get organised but can be run on virtually no budget and are very well received by students. A model for the development and implementation of business trips is presented

Determinants of anglers willingness to pay to support the Recreational Quota Entity program

Thesis (M.S.) University of Alaska Fairbanks, 2019This study applies data from a web-based survey administered to Alaska sport fish license holders in 2017 to examine the newly introduced Recreational Quota Entity (RQE) program in Alaska's guided halibut sport fishery and the possibility of increasing halibut available to sport anglers by funding this program through a state-endorsed halibut stamp. Two valuation questions were randomized amongst the survey sample. The questions were designed to elicit willingness to pay (WTP) for a halibut stamp in support of the RQE program under (1) status quo halibut fishing regulations (2) more relaxed charter halibut fishing regulations made possible through revenues from halibut stamp sales. The need for two valuation questions is in response to the many factors that would ultimately determine the degree to which charter fishing regulations could be relaxed and the time needed for regulatory change made possible through revenues from halibut stamp sales. The findings indicate that non-resident anglers and resident anglers have a very similar WTP for a state-endorsed halibut stamp and that anglers are willing to pay for a halibut stamp despite having little or no history of participation in the halibut fishery. The pairwise comparison among mean WTP estimates from both valuation questions indicates that differences in anglers' WTP are inconsequential. Findings suggest that the WTP for a state-endorsed halibut stamp reflects an interest in preserving access to the fishery or the value of reserving an option to participate in the halibut fishery. Respondent education level and employment status were found to be statistically significant determinants of anglers' willingness to pay for a state-endorsed halibut stamp to support the RQE program

The positive side of a negative reference: the delay between linguistic processing and common ground

Interlocutors converge on names to refer to entities. For example, a speaker might refer to a novel looking object as the jellyfish and, once identified, the listener will too. The hypothesized mechanism behind such referential precedents is a subject of debate. The common ground view claims that listeners register the object as well as the identity of the speaker who coined the label. The linguistic view claims that, once established, precedents are treated by listeners like any other linguistic unit, i.e. without needing to keep track of the speaker. To test predictions from each account, we used visual-world eyetracking, which allows observations in real time, during a standard referential communication task. Participants had to select objects based on instructions from two speakers. In the critical condition, listeners sought an object with a negative reference such as not the jellyfish. We aimed to determine the extent to which listeners rely on the linguistic input, common ground or both. We found that initial interpretations were based on linguistic processing only and that common ground considerations do emerge but only after 1000 ms. Our findings support the idea that-at least temporally-linguistic processing can be isolated from common ground

Library Instruction and Themed Composition Courses: An Investigation of Factors that Impact Student Learning

Many academic libraries partner with English composition in order to teach first year students skills related to academic research and writing. Due to the partnership between information literacy and first-year writing programs, it is important to evaluate how these programs can best support one another. The purpose of this study was to examine the impact of two factors on student information literacy skill development: library instruction and section theme—defined here as class sections of the English 102 (ENG 102) program developed around a central topic selected by the instructor. A random sample of annotated bibliographies from 95 sections of ENG 102 were scored with two information literacy rubrics in order to find out if scores differed between sections based on the variables of library instruction and theme. The results of this study indicate that sections of the ENG 102 program that attended an information literacy instruction session scored significantly higher on the annotated bibliography assignment than sections that did not attend. We also found that themed sections of ENG 102 scored marginally higher on the annotated bibliography than non-themed sections of ENG 102. Implications for further research are discussed, including the potential impact of theme-based writing on information literacy learning
