HEALth Case Studies
This program was designed for dental hygiene and dentistry students to help them learn about evidence-based dentistry and its role in providing quality dental care. This program uses patient-based case studies combined with interactive tools and activities to help students become effective consumers of oral health research data. They learn to locate, evaluate, and use the outcomes of research studies to improve patient assessment, diagnosis, clinical decision making, and treatment planning, as w
Synthetic repurchase programs through put derivatives: theory and evidence
A Synthetic Repurchase is an open market share repurchase program enhanced with sales of put derivatives on the firm’s own stock. Microsoft, in 1999, using a synthetic repurchase program sold put derivatives on its own stock and received $766 million in premiums and, at the same time, signaled that it is a good-quality company and certified its future earnings. I present theoretical rationale that explains why a synthetic repurchase program provides an efficient signal about a firm’s future

Microencapsulation for therapeutic applications
Microencapsulation has proved to be a powerful technique in the field of drug delivery. A great deal of research is directed towards studying the use of various microencapsulation systems for that purpose. This study investigates the use of microencapsulation in alginate for protein delivery and delivery of gene therapy products for the treatment of spinal cord injury. Liposomes were encapsulated in alginate to form a drug delivery system which allows for multiple control points for drug release
Comprehension of emotion in neurodegenerative disorders
Recent evidence indicates that the posterior corpus callosum is smaller in patients with Alzheimer's disease (AD). Conversely, it has been demonstrated that patients with frontal systems deficits also have degradation of the anterior corpus callosum. Although these investigations indicate possible morphological relationships between the corpus callosum and cortical structures in neurodegenerative disorders, the relationship between specific neuropsychological measure of cognitive functioning and
Geologic time: Eons, eras, and epochs
Not a geology major or mathematician? No worries! This publication contains resources designed to do three things. The first is to complement teacher content knowledge and its relationship to the nature of geologic science. Geology is not a laboratory-based science lending itself to traditional notions of controlled experiments; rather it is a historical science requiring different methods. Second, we supply teachers with hands-on/minds-on lessons to develop student understanding, and third, we
Design, optimization and in vivo evaluation of a tissue-engineered anterior cruciate ligament replac
This thesis examined the development of a tissue-engineered ligament (TEL) for anterior cruciate ligament (ACL) repair and replacement. There was an in vitro evaluation of the cellular response to the TEL and an in vivo evaluation of the optimized TEL as an ACL replacement. Scaffold fabrication was based upon the use of poly ([Greek small letter alpha]-hydroxyester) acid fibers arranged in a 3-dimensional (3-D) braided structure. In vitro cellular evaluation of the poly(lactide-co-glycolide) (PL
Prototypical self-optimizing package for parallel implementation of fast signal transforms (A)
This thesis presents a self-adapting parallel package for computing the Walsh-Hadamard transform (WHT), a prototypical fast signal transform, similar to the fast Fourier transform. Using a search over a space of mathematical formulas representing different algorithms to compute the WHT, the package finds the best parallel implementation on a given shared-memory multiprocessor. The search automatically fins the best combination of sequential and parallel code leading to effective granularity, loa

Ratios for all occasions
A central theme in the middle school mathematics curriculum, proportional reasoning is based on making sense of ratios in a variety of contexts. The resources chosen for this unit provide practice in solving problems, often informally, in the format of ga

Carbon nanotube reinforced carbon nano composite fibrils by electro-spinning
Fibers of Polyacrylonitrile (PAN) are the precursor of 90% of produced carbon fibers. It is generally thought that the better the degree of molecular orientation in the original PAN fiber, the better the mechanical properties, in particular the modulus of the resultant fibers. Electro-spinning is a unique process in that it is able to produce polymer fibers having diameters ranging over seve ral orders of magnitude, from the micrometer range typical of conventional fibers down to the nanometer r
Positioning and Navigation: Services for open educational practices
To choose suitable resources for personal competence development in the vast amount of open educational resources is a challenging task for a learner. Starting with a needs analysis of lifelong learners and learning designers we introduce two wayfinding services that are currently researched and developed in the framework of the Integrated Project TENCompetence. Then we discuss the role of these services to support learners in finding and selecting open educational resources and finally we give
Real Remote Mass Spring Laboratory Experiments across Internet–Inherent Part of Integrated E-Learni
The paper presents the application of Integrated e- Learning, presented in general terms at this conference [1], exemplified on one of the most important parts of Physics - the thematic block “Oscillations“. The goal of the course of Physics in the chapter of Oscillations is to show the oscillatory movement as a basis of nearly all natural phenomena. The unifying model for all real world systems then may be the mass-spring system constituting the mechanical oscillator. The three constituting c
Supporting a Learner Community with Software Agents
This paper describes a multi- agent approach that aims at supporting learners involved in a collective activity. We consider pedagogical situations where students have to explicitly define the articulation of their collective work and then achieve the different tasks they have defined. Our objective is to support these students by taking some of these tasks in charge whilst making them work out such organisation features. For this purpose, we propose to consider that the group of students forms
Monarchs, People, and History, Summer 2008
The origins and reasons for monarchy as an institution and social force in the Western world. Specific royal personages are studied with attention to how they attained or lost effectiveness as leaders; their goals for themselves and their people are stressed. These themes are explored through primary source readings. Architectural, artistic, and musical evidence are introduced in slide and tape sessions.
Liberty, Equality, Fraternity: Exploring the French Revolution
This accessible and lively introduction to the French Revolution presents an extraordinary archive of some of the most important documentary evidence from the Revolution, including 338 texts, 245 images, and a number of maps and songs
Authoring Intelligent Tutoring Systems:
An analysis of the state of the art
This paper consists of an in-depth summary and analysis of the research and development state of the art for intelligent tutoring system (ITS) authoring systems. A seven-part categorization of two dozen authoring systems is given, followed by a characterization of the authoring tools and the types of ITSs that are built for each category. An overview of the knowledge acquisition and authoring techniques used in these systems is given. A characterization of the design tradeoffs involved in buildi
Four Easy Pieces: Development Systems for Knowledge-Based Generative Instruction
The Experimental Advanced Design Advisor (XAIDA) is a system for the development of computer-based maintenance training. XAIDA acquires knowledge of a device from a subject matter expert and applies common maintenance-training procedures to generate interactive training from the description. XAIDA provides maintenance training in four areas: the physical characteristics of a device, its theory of operation, operating and maintenance procedures, and troubleshooting. XAIDA relies on an instruction
