Twenty Thousand Palindromic And S
On page 96 of I Love Me, Vol. I, Michael Donner suggests that the ordinary possibilities of the English palindrome are so close to being exhausted that, if new work is to be produced, it may become necessary to enlist the aid of obscure abbreviations in the collection by Ralph de Sola. Word Ways editor A. Ross Eckler perhaps also has in mind the \u27drome may be used up when he remarks on page 291 of the November issue that palindromes are not very important to Word Ways because they follow well-trodden paths
Test of Conformal Invariance in One-Dimensional Quantum Liquid with Long-Range Interaction
We numerically study the momentum distribution of one-dimensional Bose and
Fermi systems with long-range interaction for the ``special'' values
, singled out by random matrix theory. The critical
exponents are shown to be independent of density and in excellent agreement
with estimates obtained from conformal finite-size scaling analysis.Comment: 25 page
Intercalation and High Temperature Superconductivity of Fullerides
Intercalation of polyatomic molecules into a superconductor can drastically
affect the properties of the compound. A mechanism leading to a large increase
in Tc for such systems is proposed. It explains the recent remarkable
observation of high Tc superconductivity in the hole-doped C60/CHX3 (X=Cl,Br)
compounds and the large shift in their Tc upon Cl->Br substitution. The
increase in Tc is due to contribution to the pairing arising from the
interaction of electrons with the vibrational manifold of the molecule. The
proposed mechanism opens up the possibility to observe a site-selective isotope
effect. We also suggest that intercalating CHI3 would further increase the
critical temperature to Tc=140K.Comment: Final expanded version of cond-mat/0109553 and cond-mat/0110327 with

Researchers at the Gate: Factors Influencing Districtsâ Right of Entry Decisions
Background: The No Child Left Behind legislation creates an increased need for new school-based empirical studies whose implementation will depend largely on researchersâ access to various school populations and records. Access decisions are typically made by superintendents, or their designees, functioning as gatekeepers who control right of entry. Understanding the factors driving these decisions could enhance the desirability of proposals and increase access rates for quantitative and qualitative researchers alike. Purpose: The purpose of this research was to query districts about four key access factors including (a) researcher trustworthiness, (b) associated risks, (c) costs and benefits, and (d) potential contribution to the field. Research Method: This study used a series of interviews followed by a systematic survey.
Participants: Ten superintendents were interviewed followed by a survey of 310 districts in Connecticut, Illinois, and Pennsylvania. Findings: Although trustworthiness was expected to supercede other factors, districts reported greater interest in elements of risk and in research having widespread educational value. Costs and material benefits (e.g., equipment, credit, and compensation) were not highly emphasized nor relatively important. Professional development, planning, and instructional benefits mattered more. Implications for Research and Practice: Given the increasing emphasis on scientifically based research for school decision-making and program reform, the present study is notable for two reasons. First, it provides researchers with insights into the decision-making process involved in granting permission to conduct research in the schools. Second, it can help to improve the quality of proposals received by school districts, thereby increasing the likelihood of positive right-of-entry decisions and resulting in better informed decisions
Supporting Catholic Education through Effective School/University Partnerships: Two Models from the 2012 Catholic Higher Education Collaborative Conference
This essay was developed from a panel presentation by Henk and Maney, as well as other key professional colleagues, delivered at the 2012 CHEC Conference. The essay describes the formation and initial work of a consortium of five institutions of higher education in the greater Milwaukee area, including Alverno College, Cardinal Stritch University, Marian University, Marquette University, and Mount Mary College
Measuring the Reader Self-Perceptions of Adolescents: Introducing the RSPS2
This paper introduces a new affective instrument for assessing the reader self-perceptions of students in grades seven through ten. The Reader Self-Perception Scale 2 (RSPS2) builds upon its predecessor, the RSPS, a tool that measures the reading efficacy beliefs of children in grades four through six. New items were created for the RSPS2 to reflect differences in the expectations for adolescent reading. The instrument was piloted on 488 students, revised, and then validates with an additional 2,542 students in the target grades. Factor analytic procedures revealed four factors emerging on the RSPS2. Items for Progress, Observational Comparison, Social Feedback, and Physiological States clustered as expected into scales with reliabilities ranging from .87 to .95. The article includes a description of the instrument, an explanation of its possible uses in assessment, instruction, and research, as well as directions for administration, scoring, and interpretation
Open to Ideas: Information flows from Dairy Directions to Dairy Farmers
The âopennessâ of farming systems that is the focus of this paper is âopen to informationâ, in particular the way that new information from the farming systems research project, Dairy Directions, flows from research outputs to dairy farmers. Dairy Directions is a multidisciplinary research activity centred on a steering group of interested parties, mostly farmers, scientists and economists, but also drawing on extension agents, natural resource managers, water service providers, community service providers and public policy participants. The core general research question of Dairy Directions is âWhat options do farmers running different dairy farming systems have to achieve their goals in an uncertain future?â The goals analysed by the project are predominantly economic and financial â maintaining or increasing profit and cash flow, growing wealth, managing risk, preparing for succession and balancing the dairy work-life balance. Their uncertain future encompasses variability in prices, as well as the natural environment and the policy setting.Farm Management,
STATIC MODELING OF DYNAMIC RECREATION BEHAVIOR: IMPLICATIONS FOR PREDICTION AND WELFARE ESTIMATION
This paper examines the consequences of using a static model of recreation trip-taking behavior when the underlying decision problem is dynamic. In particular, we examine the implications for trip forecasting and welfare estimation using a panel dataset of Lake Michigan salmon anglers for the 1996 and 1997 fishing seasons. We derive and estimate both a structural dynamic model using Bellman's equation, and a reduced-form static model with trip probability expressions closely mimicking those of the dynamic model. We illustrate an inherent identification problem in the reduced-form model that creates biased welfare estimates, and we discuss the general implications of this for the interpretation of preference parameters in static models. We then use both models to simulate trip taking behavior and show that although their in-sample trip forecasts are similar, their welfare estimates and out-of-sample forecasts are quite different.Research Methods/ Statistical Methods,
Are Drivers\u27 Manuals Understandable?
In 1984, researchers determined that the readability of state drivers\u27 manuals exceeded the average literacy levels in the United States. Because text complexity threatened the ability of license applicants and practicing drivers to understand the information presented in the manuals, a potential safety risk was indicated. This study analyzes recent editions of the manuals using readability formulas and formal text presentation ratings. It was found that the average difficulty of the drivers\u27 manuals was reduced by more than one grade level and that the 1994 manuals are clearly superior to their earlier versions, but that, in the interest of highway safety, improvements should still be sought
