In a data streaming model, a data owner releases records or documents to a set of users with matching interests, in such a way that the match in interest can be calculated from the correlation between each pair of document and user query. For scalability and availability reasons, this calculation is delegated to third-party servers, which gives rise to the need to protect the integrity and privacy of the documents and user queries. In this paper, we propose a server-aided data stream monitoring scheme (DSM) to address the aforementioned integrity and privacy challenges, so that the users are able to ...


Facilitating Student Engagement Research: A Historical Analogy For Understanding And Applying Naturalistic Inquiry, Lane G. Perry III, April Perry 2017 Western Carolina University

Facilitating Student Engagement Research: A Historical Analogy For Understanding And Applying Naturalistic Inquiry, Lane G. Perry Iii, April Perry

Journal of Research Initiatives

This paper offers a historical theoretical discussion and practical perspective on the qualitative paradigm of inquiry referred to as Naturalistic Inquiry (Lincoln & Guba, 1985). Moreover, it endeavors to demonstrate the paradigm’s versatility and usefulness when attempting to illuminate phenomena that specifically occur when students experience and interact with engaging, innovative, and experientially based pedagogies (e.g., service-learning, work-integrated learning, community-based learning). This paper presents and paradigmatically supports the researchers’ worldview through a logical primacy and discussion of ontological, epistemological, axiological, and methodological perspectives (Guba & Lincoln, 2001). Following this, Naturalistic Inquiry is identified as a paradigm of inquiry that aligns ...


Calculus Reform - Increasing Stem Retention And Post-Requisite Course Success While Closing The Retention Gap For Women And Underrepresented Minority Students, Doug Bullock, Janet Callahan, Jocelyn B.S. Cullers 2017 Boise State University

Calculus Reform - Increasing Stem Retention And Post-Requisite Course Success While Closing The Retention Gap For Women And Underrepresented Minority Students, Doug Bullock, Janet Callahan, Jocelyn B.S. Cullers

Janet M. Callahan

Boise State University (BSU) implemented an across-the-board reform of calculus instruction during the 2014 calendar year. The details of the reform, described elsewhere (Bullock, 2015), (Bullock 2016), involve both pedagogical and curricular reform. Gains from the project have included a jump in Calculus I pass rate, greater student engagement, greater instructor satisfaction, a shift toward active learning pedagogies, and the emergence of a strong collaborative teaching community. This paper examines the effects of the reform on student retention. Since the curricular reform involved pruning some content and altering course outcomes, which could conceivably have negative downstream impacts, we report on ...


Lidar Aboveground Vegetation Biomass Estimates In Shrublands: Prediction, Uncertainties And Application To Coarser Scales, Aihua Li, Shital Dhakal, Nancy F. Glenn, Lucas P. Spaete 2017 Boise State University

Lidar Aboveground Vegetation Biomass Estimates In Shrublands: Prediction, Uncertainties And Application To Coarser Scales, Aihua Li, Shital Dhakal, Nancy F. Glenn, Lucas P. Spaete

Nancy F. Glenn

Our study objectives were to model the aboveground biomass in a xeric shrub-steppe landscape with airborne light detection and ranging (Lidar) and explore the uncertainty associated with the models we created. We incorporated vegetation vertical structure information obtained from Lidar with ground-measured biomass data, allowing us to scale shrub biomass from small field sites (1 m subplots and 1 ha plots) to a larger landscape. A series of airborne Lidar-derived vegetation metrics were trained and linked with the field-measured biomass in Random Forests (RF) regression models. A Stepwise Multiple Regression (SMR) model was also explored as a comparison. Our results ...


Tunable Copper Complexes For Sustainable Photocatalysis, David Kline 2017 Murray State University

Tunable Copper Complexes For Sustainable Photocatalysis, David Kline

Posters-at-the-Capitol

Photoredox catalysis has direct applications in sustainable chemistry and thus an immense impact on our environment. With the ability to harness energy directly from the sun to catalyze useful chemical reactions, photocatalysts can help to eliminate the need for harsh reaction conditions and reduce generation of hazardous chemical waste. Photocatalysts based on Earth-abundant metals such as copper have recently emerged as sustainable alternatives to rare-earth metals including iridium and ruthenium, which are no longer required for many photocatalyzed chemical transformations.

A Spatial Collaboration: Building A Multi-Institution Geospatial Data Discovery Portal, Mara Blake, Karen Majewicz, Ryan Mattke, Kathleen W. W. Weessies

Collaborative Librarianship

As academic education and research increasingly take advantage of geospatial data and methodologies, we see a corresponding exponential growth in the number of available geospatial resources in the form of GIS datasets and scanned historical maps. However, users can experience difficulty finding these resources due to the unconnected multitude of platforms and clearinghouses that host them. Additionally, the resources are not always well described with web semantic metadata that facilitates discovery. In response to this challenge, The Big Ten Academic Alliance Geospatial Data Project began in 2015 to provide discoverability, facilitate access, and connect scholars to geospatial resources. Our project ...


Direct 3d Printing Of Catalytically Active Structures, Igor I. Slowing, J. Sebastian Manzano, Zachary B. Weinstein, Aaron D. Sadow 2017 Ames Laboratory

Direct 3d Printing Of Catalytically Active Structures, Igor I. Slowing, J. Sebastian Manzano, Zachary B. Weinstein, Aaron D. Sadow

Igor I. Slowing

3D printing of materials with active functional groups can provide customdesigned structures that promote chemical conversions. Herein, catalytically active architectures were produced by photopolymerizing bifunctional molecules using a commercial stereolithographic 3D printer. Functionalities in the monomers included a polymerizable vinyl group to assemble the 3D structures and a secondary group to provide them with active sites. The 3D-printed architectures containing accessible carboxylic acid, amine, and copper carboxylate functionalities were catalytically active for the Mannich, aldol, and Huisgen cycloaddition reactions, respectively. The functional groups in the 3D-printed structures were also amenable to post-printing chemical modification. As proof of principle, chemically active ...

The reaction of CoCl2·THF and thallium tris(4,4-dimethyl-2-oxazolinyl)phenylborate (TlToM) in tetrahydrofuran (THF) provides ToMCoCl (1) in 95 % yield; however, appropriate solvents and starting materials are required to favor 1 over two other readily formed side-products, (ToM)2Co (2) and {HToM}CoCl2 (3). ESR, NMR, FTIR, and UV/Vis spectroscopies were used to distinguish these cobalt(II) products and probe their electronic and structural properties. Even after the structures indicated by these methods were confirmed by X-ray crystallography, the spectroscopic identification of trace contaminants in the material was challenging. The recognition of possible contaminants in the synthesis of ...

The Necst Program - Networking And Engaging In Computer Science And Information Technology Program, Jerry Alan Fails

Jerry Alan Fails

In this paper, we describe the NECST Program and its innovative mentorship structure for transitioning graduate students in computer science whose undergraduate experiences may be in other disciplines. NECST employs several activities that provide the additional scaffolding to support students as they make this transition. While we believe these activities may be suited for other situations, the program helps address the unique challenges northern New Jersey faces with relation to graduate studies in computing fields.

Iowa Prairie: Original Extent And Loss, Preservation And Recovery Attempts, Daryl D. Smith 2017 University of Northern Iowa

Iowa Prairie: Original Extent And Loss, Preservation And Recovery Attempts, Daryl D. Smith

Daryl Smith

Iowa's prairie has to be assessed in the context of the pre- and post-agriculturally dominated ecosystem in which it now exists. This requires an understanding of prairies and of society's perspective of prairies. Therefore, the attitudes of people through time have to be considered; (1) those who were involved in the demise of the prairie, (2) those who helped saved the pieces of the prairie and (3) those who may be called upon to recover the prairie ecosystem.
