A Uniformly Dissipative Scheme For Stationary Statistical Properties Of The Infinite Prandtl Number Model, Wenfang (Wendy) Cheng, Xiaoming Wang
A Uniformly Dissipative Scheme For Stationary Statistical Properties Of The Infinite Prandtl Number Model, Wenfang (Wendy) Cheng, Xiaoming Wang
Mathematics and Statistics Faculty Research & Creative Works
The purpose of this short communication is to announce that a class of numerical schemes, uniformly dissipative approximations, which uniformly preserve the dissipativity of the continuous infinite dimensional dissipative complex (chaotic) systems possess desirable properties in terms of approximating stationary statistics properties. in particular, the stationary statistical properties of these uniformly dissipative schemes converge to those of the continuous system at vanishing mesh size. the idea is illustrated on the infinite Prandtl number model for convection and semi-discretization in time, although the general strategy works for a broad class of dissipative complex systems and fully discretized approximations. as far as …

A Semi-Implicit Scheme For Stationary Statistical Properties Of The Infinite Prandtl Number Model, Wenfang Cheng, Xiaoming Wang
Mathematics and Statistics Faculty Research & Creative Works
We propose a semisecret in time semi-implicit numerical scheme for the infinite Prandtl model for convection. Besides the usual finite time convergence, this scheme enjoys the additional highly desirable feature that the stationary statistical properties of the scheme converge to those of the infinite Prandtl number model at vanishing time stop. One of the key characteristics of the scheme is that it preserves the dissipativity of the infinite Prandtl number model uniformly in terms of the time stop. So far as wo know, this is the first rigorous result on convergence of stationary statistical properties of numerical schemes for infinite …

Spatial Misalignment In Time Series Studies Of Air Pollution And Health Data, Roger D. Peng, Michelle L. Bell
Spatial Misalignment In Time Series Studies Of Air Pollution And Health Data, Roger D. Peng, Michelle L. Bell
Johns Hopkins University, Dept. of Biostatistics Working Papers
Time series studies of environmental exposures often involve comparing daily changes in a toxicant measured at a point in space with daily changes in an aggregate measure of health. Spatial misalignment of the exposure and response variables can bias the estimation of health risk and the magnitude of this bias depends on the spatial variation of the exposure of interest. In air pollution epidemiology, there is an increasing focus on estimating the health effects of the chemical components of particulate matter. One issue that is raised by this new focus is the spatial misalignment error introduced by the lack of …
Enhancing Homework’S Effectiveness Through Student Motivation And Parental Involvement, Jonathan T. Beutlich
Enhancing Homework’S Effectiveness Through Student Motivation And Parental Involvement, Jonathan T. Beutlich
Master of Education Program Theses
Homework has varying degrees of effectiveness; therefore, it is important for teachers to know what elements aid in making homework assignments more effective to learners. There are outside factors that contribute to homework’s effectiveness as well as types of homework assignments that will increase students’ success. Two of the factors contributing to homework’s level of benefits are student motivation and parental involvement. There are three types of homework assignments that increase the positive aspects of student motivation and parental involvement include interspersal assignments, interactive homework assignments, and project-based assignments. Improved homework benefits education, specifically Christian education, by enabling a tightly …

The ongoing credit crisis has thrown the spotlight onsovereign wealth funds (SWFs). “The size and activities of SWFs in recent years have led to heightened attention on, and suspicion about them,” commented Locknie Hsu, Singapore Management University professor who specialises in international trade and dispute settlement law. Hsu recently authored a commentary on the new set of voluntary principles, known as the ‘Santiago Principles’ or GAPP (Generally Accepted Principles and Practices), adopted and released in October 2008 to govern such funds.

Public Long-Term Care Insurance And The Housing And Living Arrangements Of The Elderly: Evidence From Medicare Home Health Benefits, Gary V. Engelhardt, Nadia Greenhalgh-Stanley
Public Long-Term Care Insurance And The Housing And Living Arrangements Of The Elderly: Evidence From Medicare Home Health Benefits, Gary V. Engelhardt, Nadia Greenhalgh-Stanley
Economics - All Scholarship
We provide empirical evidence on the extent to which long-term care insurance affects the housing and living arrangements of the elderly by examining plausibly exogenous changes in the supply of long-term care insurance through the Medicare program that occurred in the late 1990s. Prior to 1997, Medicare reimbursed home health care agencies on a retrospective-cost basis. Then, starting in October, 1997, as a result of the Balanced Budget Act of 1997 (BBA97), Medicare switched to a system of prospective payments for home health care, which induced state-by-calendar-year variation in the supply of this type of public long-term care insurance. We …

Breaking The Ice With A Gutted Rooster: Reflections On A Messy Day One, Dave O'Connell
Breaking The Ice With A Gutted Rooster: Reflections On A Messy Day One, Dave O'Connell
Organization Management Journal
Based on an experience in an MBA Human Resource Management classroom, this paper traces the process of my reflection on an icebreaker discussion of ‘‘best’’ and ‘‘worst’’ student jobs. I indicate how I developed second thoughts about the way in which I handled the discussion, concerned that making light of messy jobs might encourage the class of future managers to do the same. The journey includes the input of a fellow colleague who helped spur me to articulate more clearly – for myself and for my students – that which I am willing to profess as a management professor.

Organization Management Journal
This paper provides a systemic approach to building and sustaining a solid assurance of learning program using the framework of Kotter’s (1995) Strategic Model for Transforming Organizations. A comprehensive model for launching and sustaining a systemic approach to program review that ‘‘closes the loop’’ is shared step by step. Particular attention is paid to the organizational behaviors and processes that accompany each step, and to sharing important lessons that were learned. A review of the assessment literature in higher education and recent Advancement of Collegiate Schools of Business International (AACSB) contributions to this body of knowledge identifies a critical gap …

Secondary Electron Emission From Freely Supported Nanowires, Makoto Suzuki, Kazuhiro Kumagai, Takashi Sekiguchi, Alan M. Cassell, Tsutomu Saito, Cary Y. Yang
Electrical and Computer Engineering
We present secondary electron (SE) emission results from freely supported carbon/silicon nitride (Si3N4) hybrid nanowires using scanning electron microscopy. We found that, contrary to bulk materials, the SE emission from insulating or electrically isolated metallic nanowires is strongly suppressed by the penetrating beam. A mechanism of the SE suppression by the positive specimen charging is proposed, which is based on a total emission yield calculation using the Monte Carlo technique. This finding provides an important basis for studying low-energy electron emission from nanostructures under a penetrating electron beam.

Information Systems and Engineering Management Research Publications
Field star BD+20 307 is the dustiest known main-sequence star, based on the fraction of its bolometric luminosity, ~4%, that is emitted at infrared wavelengths. The particles that carry this large infrared luminosity are unusually warm, comparable to the temperature of the zodiacal dust in the solar system, and their existence is likely to be a consequence of a fairly recent collision of large objects such as planets or planetary embryos. Thus, the age of BD+20 307 is potentially of interest in constraining the era of terrestrial planet formation. The present project was initiated with an attempt to derive this …

Information Systems and Engineering Management Research Publications
We present new Spitzer observations of the phase variation of the hot Jupiter HD 189733b in the MIPS 24 μm bandpass, spanning the same part of the planet's orbit as our previous observations in the IRAC 8 μm bandpass (Knutson et al. 2007). We find that the minimum hemisphere-averaged flux from the planet in this bandpass is 76% ± 3% of the maximum flux; this corresponds to minimum and maximum hemisphere-averaged brightness temperatures of 984 ± 48 K and 1220 ± 47 K, respectively. The planet reaches its maximum flux at an orbital phase of 0.396 ± 0.022, corresponding to …
Abstraction As A Basis For The Computational Interpretation Of Creative Cross-Modal Metaphor, Sylvia Weber Russell
Abstraction As A Basis For The Computational Interpretation Of Creative Cross-Modal Metaphor, Sylvia Weber Russell
Computer Science
Various approaches to computational metaphor interpretation are based on pre-existing similarities between source and target domains and/or are based on metaphors already observed to be prevalent in the language. This paper addresses similarity-creating cross-modal metaphoric expressions. It is shown how the “abstract concept as object” (or reification) metaphor plays a central role in a large class of metaphoric extensions. The described approach depends on the imposition of abstract ontological components, which represent source concepts, onto target concepts. The challenge of such a system is to represent both denotative and connotative components which are extensible, together with a framework of general …

Integrating Landscapes That Have Experienced Rural Depopulation And Ecological Homogenization Into Tropical Conservation Planning, Aerin L. Jacob, Ismael Vaccaro, Raja Sengupta, Joel N. Hartter, Colin A. Chapman
Geography
If current trends of declining fertility rates and increasing abandonment of rural land as a result of urbanization continue, this will signal a globally significant transformation with important consequences for policy makers interested in conservation planning. This transformation is presently evident in a number of countries and projections suggest it may occur in the future in many developing countries. We use rates of population growth and urbanization to project population trends in rural areas for 25 example countries. Our projections indicate a general decline in population density that has either occurred already (e.g., Mexico) or may occur in the future …

Uncompressed high-definition video streaming over wireless personal area networks is a challenging problem because of the high data rate requirement and channel variations. With the advances in RF technology and the huge bandwidth available worldwide in the 57–66 GHz millimeter-wave unlicensed spectrum, mmWave WPANs that can support multigigabit transmission are being developed. However, compared to low-frequency signals (2.4 or 5 GHz), mmWave signals are more fragile; indeed, the propagation losses are significantly higher. In this article we present an mmWave system for supporting uncompressed HD video up to 3 Gb/s. The system includes various efficient error protection and concealment schemes …
