A Bibliometric Content Analysis Of Do-It-Yourself (Diy) Science: Where To From Here For Management Research?, Peter Galvin, Anton Klarin, Richard Nyuur, Nicholas Burton

Research outputs 2014 to 2021

Do-it-yourself (DIY) science research is currently in an expansion phase both in terms of its depth (with an increasing number of papers published each year) and its scope (with the core ideas being linked to an increasing number of constructs). To develop a more holistic appreciation of how the field has developed and to identify potential avenues of future research we undertake a bibliometric content analysis of the DIY science literature post 1980. We find four major clusters pertaining to education, culture, the operationalising of DIY science (including commercialisation) and technology-related issues. We review each of these clusters and the …

High-momentum configurations of nucleon pairs at short-distance are probed using measurements of the C-12(e, e' p) and C-12(e, e' pN) reactions (where N is either n or p), at high-Q(2) and x(B) > 1.1. The data span a missing-momentum range of 300-1000 MeV/c and are predominantly sensitive to the transition region of the strong nuclear interaction from a Tensor to Scalar interaction. The data are well reproduced by theoretical calculations using the Generalized Contact Formalism with both chiral and phenomenological nucleon-nucleon (NN) interaction models. This agreement suggests that the measured high missing-momentum protons up to 1000 MeV/c predominantly belong to short-ranged …

Multi-Gaussian Random Variables For Modeling Optical Phenomena, Olga Korotkova, Milo W. Hyde Iv

Faculty Publications

A generalization of the classic Gaussian random variable to the family of multi-Gaussian (MG) random variables characterized by shape parameter M > 0, in addition to the mean and the standard deviation, is introduced. The probability density function (PDF) of the MG family members is an alternating series of Gaussian functions with suitably chosen heights and widths. In particular, for integer values of M, the series has a finite number of terms and leads to flattened profiles, while reducing to the classic Gaussian PDF for M = 1. For non-integer, positive values of M, a convergent infinite series of …

Identifying Geomorphological Changes Of Coastal Cliffs Through Point Cloud Registration From Uav Images, Xiangxiong Kong

Physics and Engineering Science

Cliff monitoring is essential to stakeholders for their decision-making in maintaining a healthy coastal environment. Recently, photogrammetry-based technology has shown great successes in cliff monitoring. However, many methods to date require georeferencing efforts by either measuring geographic coordinates of the ground control points (GCPs) or using global navigation satellite system (GNSS)-enabled unmanned aerial vehicles (UAVs), significantly increasing the implementation costs. In this study, we proposed an alternative cliff monitoring methodology that does not rely on any georeferencing efforts but can still yield reliable monitoring results. To this end, we treated 3D point clouds of the cliff from different periods as …

Makara Journal of Technology

X-ray diffraction techniques were performed to determine the actual crystal structure of A2 austenitic stainless steel (ASS) as-cast and A2 ASS after arc plasma sintering (APS) for 2 s. Computations were conducted on the basis of the Bragg arithmetic formula by comparing the S2 arithmetic with the interplanar spacing. The Bragg arithmetic formula is a simple series for the determination of the crystalline phase of materials based on the Miller indices of cubic shapes or other shapes. A2 ASS as-cast was identified to have a crystal structure of face-centered cubic with lattice parameter a = 3.58 Å. A similar crystal …

Forecasting Inundation Extents In The Amazon Basin Using Srh-2d And Hand Based On The Geoglows Ecmwf Streamflow Services, Christopher Hyde Edwards

Theses and Dissertations

Floods are the most impactful natural disasters on earth, and reliable flood warning systems are critical for disaster preparation, mitigation, and response. The GEOGloWS ECMWF Streamflow Services (GESS) provide forecasted streamflow throughout the world. While forecasted discharge is essential to flood warning, forecasted inundation extents are required to understand and predict flood impact. In this research, I sought to expand GESS flood warning potential by generating inundation extents from streamflow forecasts. I compared Height Above Nearest Drainage (HAND), a method beneficial for flood mapping on a watershed scale, to a 2D hydrodynamic model, specifically Sedimentation and River Hydraulics – Two …

Modulation Linearization Technique For Fm/Cw Sar Image Processing Using Range Migration, Theodore Grosch, Cyril Okhio

Faculty Articles

Linear FMCW radar suffers from impairments in range and range rate if there are errors in the modulation rate or phase discontinuities. Often, this is a result of a nonlinearity of the voltage-controlled oscillator that is in the source of the transmit and receive local oscillator. The nonlinearity can be corrected at the source by using a nonlinear control voltage or by processing the received beat frequency. Any signal processing using the later method leads to computation time and energy costs, which can be considerable in some applications. When the range migration algorithm using the Stolt Transform is used for …

Feasibility And Impact Of Liquid/Liquid-Encased Dopants As Method Of Composition Control In Laser Powder Bed Fusion, Taylor Matthew Davis

Theses and Dissertations

Additive manufacturing (AM) – and laser powder bed fusion (LPBF) specifically – constructs geometry that would not be possible using standard manufacturing techniques. This geometric versatility allows integration of multiple components into a single part. While this practice can reduce weight and part count, there are also serious drawbacks. One is that the LPBF process can only build parts with a single material. This limitation generally results in over-designing some areas of the part to compensate for the compromise in material choice. Over-designing can lead to decreased functional efficiency, increased weight, etc. in LPBF parts. Methods to control the material …

Improvement Of Electrical Properties Of Cmc-Pva Doped With Various Contents Of Lino3 As An Application For Hybrid Polymer Electrolytes, Amalia Zulkifli, Norfatihah Mazuki, Ahmad Salihin Samsudin

Makara Journal of Technology

The present work was carried out with the development of hybrid polymer electrolytes (HPEs) by using carboxymethyl cellulose (CMC)–polyvinyl alcohol (PVA) doped with different contents of lithium nitrate (LiNO3) for the determination of their structural and conduction properties. The structural analysis was conducted by using Fourier transform infra-red spectroscopy and showed the interaction between the blend host polymer and ionic dopant, which formed via the coordinating site of CMC-PVA and Li+-NO3−. The complexes of CMC-PVA doped LiNO3 led to an increment in ionic conductivity, as observed by electrical impedance spectroscopy, and the sample containing 20 wt% LiNO3 obtained the highest …

Power-Over-Tether Unmanned Aerial System Leveraged For Trajectory Influenced Atmospheric Sensing, Daniel Rico

School of Computing: Dissertations, Theses, and Student Research

The use of unmanned aerial systems (UASs) in agriculture has risen in the past decade and is helping to modernize agriculture. UASs collect and elucidate data previously difficult to obtain and are used to help increase agricultural efficiency and production. Typical commercial off-the-shelf (COTS) UASs are limited by small payloads and short flight times. Such limits inhibit their ability to provide abundant data at multiple spatiotemporal scales. In this thesis, we describe the design and construction of the tethered aircraft unmanned system (TAUS), which is a novel power-over-tether UAS configured for long-term, high throughput atmospheric monitoring with an array of …

"Like I Was An Actual Researcher": Participation And Identity Trajectories Of Underrepresented Minority And First-Generation Stem Students In Research Training Communities Of Practice, Jennifer Lynn Lindwall

Dissertations and Theses

Although calls for a more diverse workforce in biomedical fields have been widespread, racial and ethnic gaps in biomedical degree attainment remain. Contextualist perspectives seek to understand persistent STEM inequities by examining person-in-context experiences and how systemic factors filter into students' proximal contexts shaping their participation and science identity trajectories. Research training communities of practice aim to offer underrepresented minority and first-generation students support, guidance, and opportunities to learn the practices of science and construct their science identity. However, many students still choose to leave these programs. There is limited research on these students' science identity construction process and their …

Mechanisms Of Connexin-46 And -50 Intercellular Channel Function And Stability By Molecular Dynamics Simulations, Bassam George Haddad

Dissertations and Theses

Gap junctions make up a class of intercellular channels that characteristically connect the cytoplasm of directly apposed cells through large assemblies, or plaques, constituted by a multitude of intercellular channels. Gap junction mediated intercellular communication is critical for a variety of physiological functions, from coordinating electrical impulses in the heart and brain to maintaining homeostasis in most tissues. There are 21 isoforms of connexins, the constituent subunit of the gap junction, expressed in a tissue dependent manner. Gap junctions formed from different isoforms exhibit distinct biophysical properties, such as gating kinetics and sensitivity, as well as unique permeability and selectivity …

Spray-Painting The Sistine Chapel: Aesthetic Problems In Leaf By Niggle, John Holmes

Mythcon

No work of the allegoriphobic Tolkien is more manifestly allegorical than his short story “Leaf By Niggle.” Because of the story’s unmistakably allegorical nature, when the reader encounters the four-word sentence that opens the second paragraph—“Niggle was a painter”—the initial response might justly be to read “painter” in a more generic sense to mean “artist in general.” Indeed, the best criticism of this story tends to read Niggle’s problem as an analogue of Tolkien’s problem as sub-creator of Middle-earth, primarily in writing. But because Tolkien’s rendering of Middle-earth sometimes took form in pencil sketches and watercolors as well, Niggle’s painterly …

Eärendil’S Errand And “Errantry”, Janet Brennan Croft, David Bratman, David Emerson, Verlyn Flieger

Mythcon

Tolkien’s love of word play legitimizes considering the linguistic closeness of errantry, Eärendil , and errand. This leads to the points this panel will consider: Tolkien has more than once taken themes and motifs first used in a lighter story and woven them, in more serious form, into his broader legendarium; for example, The Hobbit’s Bard presages Aragorn, and its lower-case ring the centrally important Ring of the longer work. Eärendil is supposed to have been the subject of one of the great tales, but we never get it in its full form, or more comparably, in multiple forms …

Pilot-Scale H2S And Swine Odor Removal System Using Commercially Available Biochar, Kyoung S. Ro, Brian Woodbury, Mindy Spiehs, Ariel A. Szogi, Philip J. Silva, Okhwa Hwang, Sungback Cho

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Although biochars made in laboratory seem to remove H2S and odorous compounds effectively, very few studies are available for commercial biochars. This study evaluated the efficacy of a commercial biochar (CBC) for removing H2S and odorous volatile organic compounds (VOCs). We found that the well-known Ergun equation may not be adequate in predicting pressure drop for properly sizing a ventilation system. The H2S breakthrough adsorption capacity of the CBC was 2.51 mg/g under humid conditions, which was much higher than that for dry conditions. The breakthrough capacity increased with the influent concentration of H2S. The efficacy of a pilot-scale biochar …

Factors Influencing Physicians’ Continuous Blogging: A Survey, I. Chiu Chang, Kuei Chen Cheng, Hui Mei Hsu, David C. Yen

Background: Health information can be more easily transmitted and diffused through the Internet, but questionable online health information often misinforms patients. Physicians have a duty to inform patients how to achieve positive health outcomes. Many physicians often write blogs to provide patients with the right health information. However, most articles available on this sub-ject only describe the blog phenomena without providing a theoretical background and an empirical analysis of doctors using blogs. Methods: This study based on social cognitive theory (SCT) explores the factors influencing physicians’ intention of continuously blogging. A total of 887 physician blog-gers were invited to participate …

The Role Of Dnd1 In Cancers, Yun Zhang, Jyotsna D. Godavarthi, Abie Williams-Villalobo, Shahrazad Polk, Angabin Matin

Faculty Publications

The Ter mutation in Dead-End 1 (Dnd1), Dnd1Ter, which leads to a premature stop codon, has been determined to be the cause for primordial germ cell deficiency, accompanied with a high incidence of congenital testicular germ cell tumors (TGCTs) or teratomas in the 129/Sv-Ter mice. As an RNA-binding protein, DND1 can bind the 3′-untranslated region (3′-UTR) of mRNAs and function in translational regulation. DND1 can block microRNA (miRNA) access to the 3′-UTR of target mRNAs, thus inhibiting miRNA-mediated mRNA degradation and up-regulating translation or can also function to degrade or repress mRNAs. Other mechanisms of DND1 activity include promoting translation …

Intended And Unintended Effects Of E-Cigarette Taxes On Youth Tobacco Use, Rahi Abouk, Charles J. Courtemanche, Dhaval Dave, Bo Feng, Abigail S. Friedman, Johanna Catherine Maclean, Michael F. Pesko, Joseph J. Sabia, Samuel Safford

Institute for the Study of Free Enterprise Working Papers

Over the past decade, rising youth use of e-cigarettes and other electronic nicotine delivery systems (ENDS) has prompted aggressive regulation by state and local governments. Between 2010 and 2019, ten states and two large counties adopted ENDS taxes. Applying a continuous treatment difference-in-differences approach to data from two large national datasets (Monitoring the Future and the Youth Risk Behavior Surveillance System), this study explores the impact of ENDS taxes on youth tobacco use. We find that ENDS taxes reduce youth e-cigarette consumption, with estimated e-cigarette tax elasticities of -0.06 to -0.21. However, we estimate sizable positive cigarette cross-tax elasticities, suggesting …

The Relationship Between International Financial Reporting Standards And Foreign Direct Investment Flows: Case Of Countries With Economies In Transition, Rustam Abduraupov Dsc, Farrukh Ibragimov, Ramz Abduraupov

International Finance and Accounting

This study examines the impact of the adoption of International Financial Reporting Standards (IFRSs) on foreign direct investment (FDI) flows in 17 transition economies based on data from 2000-2016. To test the reliability of the analysis results we have used the combined Ordinary Least-Squares regression, the Hausman test, Panel-Corrected Standard Errors, Generalized Method of Moments, Difference-in-Difference method. Our results were significantly different from the results of other similar studies. Although previous studies and analyzes have noted that the adoption of IFRSs has had a positive impact on the FDI flow, it has had a negative impact in our work.
