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
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

Essential Science for Teachers: Physical Science
In-depth interviews with children that uncover their ideas about the topic at hand.,This segment shows how the interviewer uses phenomena to develop the idea that the salt in a solution has not disappeared and it can be recovered. He presents the beaker of salt with water evaporated and the segment shows how he helps the student reconcile his ideas about the salt going away and the weight being less with the scientific explanation.
Essential Science for Teachers: Physical Science
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer is using the phenomenon of salt dissolving in water to build upon the student's previous ideas about mixing substances together. This time the student sees one of the substances as "disappearing." Even though he says the mixture will still taste salty, which is evidence that there is salt in the water, he shows that he holds on to a belief that the salt has disappeared and is gone.
A Gallery of Institutional Projects
This pilot effort between the two foundations is designed to help institutions and programs create succinct project portals that provide quick access to a project overview and selected instruments, materials, data and evidence related to their work.

L'article expose la méthodologie et quelques illustrations du travail didactique d'analyse des connaissances et du système d'enseignement / apprentissage en milieu hospitalier (chirurgie orthopédique). La prise en compte dans l'E
Les avis individuels sont-ils pris en compte lors d'une activité collaborative à distance ? Quels
Cet article a pour objectif de mettre en évidence de quelle manière les avis individuels sont pris en considération lors d'une activité collaborative. Nous nous attacherons à vérifier tout d'abord dans quelle mesure les avis individuels des 96 sujets de notre échantillon se modifient ou non selon la modalité de travail collaboratif (modalités de constitution de la paire, consignes collaboratives visant ou non au consensus) à laquelle ils sont confrontés (question de recherche 1). Ensu
Empirical Research Methods
Regression analysis is an enormously popular and powerful tool, used ubiquitously in the social and behavioral sciences. Most courses on the subject immediately dive into the mathematical aspects of the subject and illustrate the technique on problems that are already highly structured. As a result, most students come away with little idea of the wide range of problems to which regression analysis can be applied and how to represent those problems in a way that cleverly utilizes readily availabl
Does excessive exposure to violent video games cause violent behavior? Does increased gun availability cause more crime or less? Causal claims permeate everyday life and are constantly the subject of "studies" reported in the newspaper. The material in Causal and Statistical Reasoning examines the nature of causal claims and the statistical sorts of evidence used to support them. The material is contained in: approximately 20 content modules, a repository of over 100 short case studies, and a "C
Making sens: science education networks of sensors
A small group of leaders from research, industry, and education convened in a one-day workshop at Stanford's Center for Innovations in Learning (SCIL) to brainstorm on the use of data probes, sensors, and communication technologies in the development of innovative science education curricula. This report documents the results of a morning brainstorm and afternoon group exercises developing educational scenarios for which sensor networks would be powerful in enhancing learning content and promoti
LSE Literary Weekend - Literature and the Academic: Literature as a resource for other disciplines
The session examines how the reading of literature can expand the analytical imagination, provide alternative metaphors and supply vital empirical evidence. Three academics from very different disciplines discuss ways in which literature can be invaluable to the broader research community.
Middle School Portal: Math and Science Pathways (MSP2)
In this interactive exercise, students in grade 6 and up determine if a Mars rover should look for evidence of life on or underneath the Martian surface. To make this determination, students process visual and textual information about how four factors (cosmic radiation, ultraviolet radiation, temperature, and presence of water) impact Earth and Mars. They look at each factor in isolation by reading a brief explanation of its effect on life, analyzing cartoon-like images of its influence on Eart
Middle School Portal: Math and Science Pathways (MSP2)
This online activity offers students a chance to analyze data stated as percentages to draw conclusions about the similarity of five archeological sites. Students analyze the data by making a table of the differences for each pair of sites by subtracting the smaller percentage from the larger for each of five types of evidence. The activity is one of 80 mathematical challenges featured on the Figure This! web site, where real-world uses of mathematics are emphasized. The activity features a solu

Prostate Cancer Screening Decision Making Under Controversy: Implications for Health Promotion Pract
Prostate cancer is a major health problem for U.S. men and is characterized by paradoxes and controversies. Despite the wide availability of the prostate-specific antigen (PSA) test, prostate cancer screening remains a controversial practice mainly because the direct impact of screening on mortality is not yet proven. As the relative value of screening, early detection, and treatment strategies continue to be debated, glaring racial-ethnic disparities persist with African American men experienci
