Variations In Solar Wind Fractionation As Seen By Ace/Swics And The Implications For Genesis Mission Results, P. Pilleri, Daniel B. Reisenfeld, T. H. Zurbuchen, S. T. Lepri, P. Shearer, J. A. Gilbert, R. Von Steiger, R. C. Wiens

Physics and Astronomy Faculty Publications

We use Advanced Composition Explorer (ACE)/Solar Wind Ion Composition Spectrometer (SWICS) elemental composition data to compare the variations in solar wind (SW) fractionation as measured by SWICS during the last solar maximum (1999-2001), the solar minimum (2006-2009), and the period in which the Genesis spacecraft was collecting SW (late 2001-early 2004). We differentiate our analysis in terms in SW regimes (i.e., originating from interstream or coronal hole flows, or coronal mass ejecta). Abundances are normalized to the low-first ionization potential (low-FIP) ion magnesium to uncover correlations that are not apparent when normalizing to high-FIP ions. We find that relative …

Deaf Children’S Science Content Learning In Direct Instruction Versus Interpreted Instruction, Kim B. Kurz, Brenda Schick, Peter C. Hauser

Journal of Science Education for Students with Disabilities

This research study compared learning of 6-9th grade deaf students under two modes of educational delivery – interpreted vs. direct instruction using science lessons. Nineteen deaf students participated in the study in which they were taught six science lessons in American Sign Language. In one condition, the lessons were taught by a hearing teacher in English and were translated in ASL via a professional and certified interpreter. In the second condition, the lessons were taught to the students in ASL by a deaf teacher. All students saw three lessons delivered via an interpreter and three different lessons in direct ASL; …

Pbl In The Era Of Reform Standards: Challenges And Benefits Perceived By Teachers In One Elementary School, Nahid Nariman, Janet Chrispeels

Interdisciplinary Journal of Problem-Based Learning

We explore teachers’ efforts to implement problem-based learning (PBL) in an elementary school serving predominantly English learners. Teachers had an opportunity to implement the Next Generation Science Standards (NGSS) using PBL in a summer school setting with no test-pressures. To understand the challenges and benefits of PBL implementation, a case study method was used and a variety of data collected. Results suggest collaboration amongst teachers is essential to design and implement PBL units. A challenge was the tension between the contradictory accountability and curriculum coverage goals of the regular academic year versus letting go to promote inquiry. Both teachers and …

Cladribine, 2-chloro-2′-deoxyadenosine, is a highly efficacious, clinically used nucleoside for the treatment of hairy cell leukemia. It is also being evaluated against other lymphoid malignancies and has been a molecule of interest for well over half a century. In continuation of our interest in the amide bond-activation in purine nucleosides via the use of (benzotriazol-1yl-oxy)tris(dimethylamino)phosphonium hexafluorophosphate, we have evaluated the use of O6-(benzotriazol-1-yl)-2′-deoxyguanosine as a potential precursor to cladribine and its analogues. These compounds, after appropriate deprotection, were assessed for their biological activities, and the data are presented herein. Against hairy cell leukemia (HCL), T-cell lymphoma (TCL) and chronic lymphocytic …

National Drought Mitigation Center: Faculty Publications

Seventy-six participants, including experts from seven countries from the Greater Horn of Africa (GHA) and project coinvestigators from the United States, met to discuss experimental seasonal prediction models and products for the GHA, to engage decision-makers and users in the assessment of hydroclimatic information requirements, and to use feedback to build a framework to support decision-making and disaster management. In pre- and postworkshop surveys, workshop participants were asked how the utility of forecasts to decision-makers might be improved. Their recommendations are presented

Peer-Mediated Interventions For Students Classified With Emotional And Behavioral Disorders, Erin M. Burns

Counselor Education Capstones

It is critical for students with disabilities to be placed in the least restrictive environment (LRE) so they are able to reap the benefits of peer interaction, thereby obtaining a sense of belonging and inclusivity. Peer-mediated interventions are necessary to consistently place students in the least restrictive environment and ensure student success. Peer-mediated interventions also assist teachers in holding all students accountable. The three-tiered model provides an outline for prevention and intervention strategies that assist in maximizing student potential in the least restrictive environment. A review of literature focuses on effective peer-mediated interventions for students classified with emotional and behavioral …

Prediction: The Quintessential Model Validation Test, Wayne Wakeland

Systems Science Friday Noon Seminar Series

It is essential to objectively test how well policy models predict real world behavior. The method used to support this assertion involves the review of three SD policy models emphasizing the degree to which the model was able to fit the historical outcome data and how well model-predicted outcomes matched real world outcomes as they unfolded. Findings indicate that while historical model agreement is a favorable indication of model validity, the act of making predictions without knowing the actual data, and comparing these predictions to actual data, can reveal model weaknesses that might be overlooked when all of the available …

Spin Nematics, Valence-Bond Solids, And Spin Liquids In So(N) Quantum Spin Models On The Triangular Lattice, Ribhu K. Kaul

Physics and Astronomy Faculty Publications

We introduce a simple model of SO(N) spins with two-site interactions which is amenable to quantum Monte Carlo studies without a sign problem on nonbipartite lattices. We present numerical results for this model on the two-dimensional triangular lattice where we find evidence for a spin nematic at small N, a valence-bond solid at large N, and a quantum spin liquid at intermediate N. By the introduction of a sign-free four-site interaction, we uncover a rich phase diagram with evidence for both first-order and exotic continuous phase transitions.

Design Of A Vlp-Nanovehicle For Cyp450 Enzymatic Activity Delivery, Lorena Sanchez-Sanchez, Alejandro Tapia-Moreno, Karla Juarez-Moreno, Dustin P. Patterson, R. D. Cadena-Nava, T. Douglas, R. Vazquez-Duhalt

Chemistry Faculty Publications and Presentations

Background: The intracellular delivery of enzymes for therapeutic use has a promising future for the treatment of several diseases such as genetic disorders and cancer. Virus-like particles offer an interesting platform for enzymatic delivery to targeted cells because of their great cargo capacity and the enhancement of the biocatalyst stability towards several factors important in the practical application of these nanoparticles. Results: We have designed a nano-bioreactor based on the encapsulation of a cytochrome P450 (CYP) inside the capsid derived from the bacteriophage P22. An enhanced peroxigenase, CYPBM3, was selected as a model enzyme because of its potential in enzyme …

Can Observation Skills Of Citizen Scientists Be Estimated Using Species Accumulation Curves?, Steve Kelling, Alison Johnston, Wesley M. Hochachka, Marshall Iliff, Daniel Fink, Jeff Gerbracht, Carl Lagoze, Frank A. La Sorte, Travis Moore, Andrea Wiggins, Weng-Keen Wong, Chris Wood, Jun Yu

Information Systems and Quantitative Analysis Faculty Publications

Volunteers are increasingly being recruited into citizen science projects to collect observations for scientific studies. An additional goal of these projects is to engage and educate these volunteers. Thus, there are few barriers to participation resulting in volunteer observers with varying ability to complete the project’s tasks. To improve the quality of a citizen science project’s outcomes it would be useful to account for inter-observer variation, and to assess the rarely tested presumption that participating in a citizen science projects results in volunteers becoming better observers. Here we present a method for indexing observer variability based on the data routinely …

Meaning, Being And Expression: A Phenomenological Justification For Interdisciplinary Scholarship, Neal Deroo

Faculty Work Comprehensive List

The purpose of this talk is two-fold: first, to lay out a phenomenological justification for why scientific or theoretical investigation must be carried out both within particular disciplines and across various disciplines; and second, to show that such a justification--alluded to with varying levels of explicitness in various works by various figures--itself opens new paths of exploration for phenomenology.

Implementing Legal Strategies For Creating Safe And Supportive School Environments, Susan Cole

Journal of Applied Research on Children: Informing Policy for Children at Risk

As many as 50% of all children, according to the Adverse Childhood Experiences Study, come to school each day having experienced serious traumatic events, including abuse, neglect, witnessing violence, and various forms of household dysfunction. For many students, these experiences and others, such as homelessness and bullying, may cause a trauma reaction that can have significant effects on their ability to learn. Students need a safe and supportive school-wide environment to help them form positive relationships, calm their emotions and behaviors, and focus, so that they can learn and be successful at school.

Current laws often put barriers in the …

The dwarf stars in the 26 year period binary α Com were predicted to eclipse each other in early 2015. That prediction was based on an orbit model made with over 600 astrometric observations using micrometers, speckle interferometry, and long baseline optical interferometry. Unfortunately, it has been realized recently that the position angle measurements for three of the observations from ∼100 years ago were in error by 180°, which warped the orbital fit. The eclipse was likely 2 months earlier than predicted (MJD 56979, 2014 November 18 UT, 7 days before the first photometric observations of this system for the …

Uncertainty, Precaution, And Adaptive Management In Wildlife Trade, Annecoos Wiersema

Michigan Journal of International Law

Wildlife trade is big business. Legal international trade in just some of the wild animals and plants traded worldwide is estimated at $350 to $530 million per year. The United States is the primary importer of virtually every major taxon of these species, including mammals, reptiles, fish, and plants. When it comes to illegal trade, estimates of its value range from $7 to $23 billion annually, covering wild animals, fish, and timber. This illegal trade fuels organized crime and militia and terrorist groups. In the face of all this pressure, some wild species appear to be traded in sustainable amounts. …

Dynapenic Obesity And The Effect On Long-Term Physical Function And Quality Of Life: Data From The Osteoarthritis Initiative, John A. Batsis, Alicia J. Zbehlik, Dawna Pidgeon, Stephen J. Bartels

Dartmouth Scholarship

Obesity is associated with functional impairment, institutionalization, and increased mortality risk in elders. Dynapenia is defined as reduced muscle strength and is a known independent predictor of adverse events and disability. The synergy between dynapenia and obesity leads to worse outcomes than either independently. We identified the impact of dynapenic obesity in a cohort at risk for and with knee osteoarthritis on function.
