Funding Culture: An Analysis of Historic Site Preservation Policy

This paper examines the way in which public funding and tax policies are applied to federally recognized historic preservation sites and how that application influences the a variety of stakeholder communities including tax payers, historical organizations, historic property owners, and municipalities

A perspective on CELSS control issues

Some issues of Closed Ecological Life Support System (CELSS) analysis and design are effectively addressed from a systems control perspective. CELSS system properties that may be elucidated using control theory in conjunction with mathematical and simulation modeling are enumerated. The approach that is being taken to the design of a control strategy for the Crop Growth Research Chamber (CGRC) and the relationship of that approach to CELSS plant growth unit subsystems control is described

Integrating Computer Applications Into Economics Electives

Typically, undergraduate economics electives focus on content rather than methods, in spite of the fact that empirical work is fundamental to the practice of economics. This article describes an alternative approach to teaching content by using computer applications that emphasise the empirical testing or applications of the theory. Students enjoy economics courses more when they are taught in this way and lab assignments provide opportunities to teach a broad skill set that is important to many undergraduate economics majors.

Teacher Evaluations in the Special Education Setting: Voices from the Field

National policy mandates have placed greater accountability on districts and schools to improve the outcomes of every student, including students with disabilities. Teacher evaluation systems that accurately identify effective teachers and their impact on student learning have resulted in the widespread design and implementation of new teacher evaluation systems. Nevertheless, limited exploration related to the evaluation of special education teachers exists. Using a qualitative, multi-case study research design, we sought to gain insight into the perceptions and experiences of special education teachers and administrators to better understand (a) the relationship between teacher evaluation and teacher effectiveness; (b) the ways in which educators approach the challenges of applying teacher evaluation systems for special education teachers; and (c) the ways in which teacher evaluation processes support the professional growth and development of special education teachers. The challenges involved in evaluating special education teachers with a uniform teacher evaluation protocol instrument are presented. The need to be able to accurately appraise special education teachers within an inclusive classroom setting, apply criteria from the observation protocol to special education students, and lack of appraisers� knowledge of the roles and expertise of special education teachers were identified. Recommendations for improvement are provided.Educatio

Leading Change through User Experience: How End Users Are Changing the Library

Cline Library is centrally located on the Northern Arizona University (NAU) campus in Flagstaff, Arizona. The library has a staff of sixty-two, and an additional forty-six student staff. According to the Carnegie Classification of Institutions of Higher Education, NAU is classified as “R2: Doctoral Universities—Higher Research Activity.” Founded in 1899 with twenty-three students, NAU is now a public university with over 30,000 undergraduate and graduate students who learn on campus and online, across the state and beyond. NAU has built a reputation for research and scientific discovery, and over 1,000 undergraduates present at the annual Undergraduate Research Symposium. From the beginning, NAU placed students at the center, and students are the driving force behind what Cline Library does. Through a strategic planning process now underway, users and staff imagine the future for Cline Library as a people-focused experiential learning environment, which is dynamic, is proactive to user needs, and promotes both individual discovery and creative collaboration. The library’s newly crafted mission and vision state

Many-Body Density Matrices for Free Fermions

Building upon an analytical technique introduced by Chung and Peschel [M. Chung and I. Peschel, Phys. Rev. B 64, art. 064412 (2001)], we calculated the density matrix rho_B of a finite block of B sites within an infinite system of free spinless fermions. In terms of the block Green function matrix G (whose elements are G_ij = , where c_i^+ and c_j are fermion creation and annihilation operators acting on sites i and j within the block respectively), the density matrix can be written as rho_B = det(1 - G) exp[ sum_ij (log G(1 - G^{-1})_ij c_i^+ c_j]. Implications of such a result to Hilbert space truncation for real-space renormalization schemes is discussed.Comment: 12 pages in RevTeX4 format. Uses amsmath, bbold, dcolumn and mathrsfs package
