Participation And The Poor: Social Accountability Institutions And Poverty Reduction In Brazil, Michael Touchton, Brian Wampler, Natasha Borges Sugiyama

Political Science Faculty Publications and Presentations

Democracy, according to a large body of research, contributes to human development by improving citizens' lives (Prezeworkski et al. 2000; Gerrign et al. 2012; McGuire 2010; Baum and Lake 2003; Gerring et al. 2015). Broad evidence demonstrates that democracies provide higher standards of living, on average, for their citizens than authoritarian countries (Boix 2001; Brown and Hunter 2004; Brown and Mobarak 2009; Besley and Kudamatsu 2006; Lake and Baum 2001). But what is it about democratic practice that enhances the quality of its citizens' lives? Proponents argue that democratic practices such as competitive elections, checks and balances, and protection of …

A Preliminary Assessment Of Water Partitioning And Ecohydrological Coupling In Northern Headwaters Using Stable Isotopes And Conceptual Runoff Models, James P. Mcnamara

Geosciences Faculty Publications and Presentations

We combined a conceptual rainfall-runoff model and input–output relationships of stable isotopes to understand ecohydrological influences on hydrological partitioning in snow-influenced northern catchments. Six sites in Sweden (Krycklan), Canada (Wolf Creek; Baker Creek; Dorset), Scotland (Girnock) and the USA (Dry Creek) span moisture and energy gradients found at high latitudes. A meta-analysis was carried out using the Hydrologiska Byråns Vattenbalansavdelning (HBV) model to estimate the main storage changes characterizing annual water balances. Annual snowpack storage importance was ranked as Wolf Creek > Krycklan > Dorset > Baker Creek > Dry Creek > Girnock. The subsequent rate and longevity of melt were reflected in calibrated parameters …

Augmenting The Immersed Boundary Method With Radial Basis Functions (Rbfs) For The Modeling Of Platelets In Hemodynamic Flows, Varun Shankar, Grady B. Wright, Robert M. Kirby, Aaron L. Fogelson

Mathematics Faculty Publications and Presentations

We present a new computational method by extending the Immersed Boundary (IB) method with a geometric model based on parametric Radial Basis Function (RBF) interpolation of the Lagrangian structures. Our specific motivation is the modeling of platelets in hemodynamic flows, though we anticipate that our method will be useful in other applications involving surface elasticity. The efficacy of our new RBF-IB method is shown through a series of numerical experiments. Specifically, we test the convergence of our method and compare our method with the traditional IB method in terms of computational cost, maximum stable time-step size and volume loss. We …

Natural Degradation Of Earthworks, Trenches, Walls And Moats, Northern Thailand, Spencer H. Wood, Layle R. Wood, Alan D. Ziegler

Geosciences Faculty Publications and Presentations

“………..structures of this kind are hidden away securely under the thick overgrowth: thus does nature preserve what man would surely destroy” (from Sumet Jumsai, 1970)

We investigate the geometry, age, and history of several enigmatic northern Thailand earthwork entrenchments that are mostly located on hills and could not have held water to form moats. The earthworks are either oval or rectangular in map view; and they typically encircle 0.3-to-1-km² areas that do not have potsherd debris indicative of former towns. Most trenches are 3-5 m deep with inner walls 4.5-8 m high. Some encircling earthworks are concentric double trenches …

Infrasound From Volcanic Rockfalls, Jeffrey B. Johnson, Timothy J. Ronan

CGISS Publications and Presentations

Proximal infrasound arrays can robustly track rapidly moving gravity-driven mass wasting, which occurs commonly at erupting volcanoes. This study reports on detection, localization, and quantification of frequent small rockfalls and infrequent pyroclastic density currents descending the southeast flanks of Santiaguito’s active Caliente Dome in January of 2014. Such activities are identified as moving sources, which descend several hundred meters at bulk flow speeds of up to ~10 m/s, which is considerably slower than the descent velocity of individual blocks. Infrasound rockfall signal character is readily distinguishable from explosion infrasound, which is manifested by a relatively fixed location source with lower …

Lekuak: The Basque Places Of Boise, Idaho, Meggan Laxalt Mackey

History Graduate Projects and Theses

Lekuak ("Places") traces how Basque places in Boise reflect the evolution of each generation’s expression of ethnic identity in response to American societal forces of the times. The first-generation Amerikanuak (late 1800s to 1920s) predominantly expressed their ethnicity as an internally-focused, solely-Basque ethnic group and built places such as boardinghouses and frontons that met communal needs. The Tartekoak, ("in-between" second generation, 1930s to the 1950s), mostly expressed a dual Basque and American ethnic identity. Tartekoak places often revealed the individuation of this generation with single-family residences and Americanized businesses, and the Basque Center with ancestry-based membership. The Egungoak ("today" …

The Validation Of An Instrument For Evaluating The Effectiveness Of Professional Development Program On Teaching Online, Jui-Long Hung, Dazhi Yang

Educational Technology Faculty Publications and Presentations

Attending professional development (PD) on teaching online is becoming popular for teachers in today’s K-12 online education. Due to the unique characteristics of the online instructional environments, surveys become the most feasible approach to evaluate the effectiveness of PD programs. However, there is no validated, open-access instrument available to satisfy the needs. Purpose of this study is to conduct construct validity, content validity, concurrent validity, and reliability tests on an open-access instrument for K–12 PD for online teaching. With the exception of a few items that have minor issues on content and construct validity, results show that the survey is, …

A Bystander Bullying Psychoeducation Program With Middle School Students: A Preliminary Report, Aida Midgett, Diana Doumas, Dara Sears, Amanda Lundquist, Robin Hausheer

Counselor Education Faculty Publications and Presentations

This study evaluated the effectiveness of a brief, stand-alone bystander bullying psychoeducation program for middle school students. The purpose of the program was to train students to take action as peer advocates. Pre- and post-tests indicated that after completing the 90-minute psychoeducation program, students reported an increase in their ability to identify what different types of bullying look like, knowledge of bystander intervention strategies, and general confidence intervening as peer advocates. Implications for school counselors are discussed, including (1) taking a leadership role in program implementation, (2) having access to a brief, cost-effective bystander training intervention, and (3) applying the …

Modification Of Cellular Dna By Synthetic Aziridinomitosenes, Chris M. Mallory, Ryan P. Carfi, Sangphil Moon, Kenneth A. Cornell, Don L. Warner

Chemistry and Biochemistry Faculty Publications and Presentations

Two synthetic aziridinomitosenes (AZMs), Me-AZM and H-AZM, structurally related to mitomycin C (MC) were evaluated for their anticancer activity against six cancer cell lines (HeLa, Jurkat, T47D, HepG2, HL-60, and HuT-78) and tested for their DNA-modifying abilities in Jurkat cells. Cytotoxicity assays showed that Me-AZM is up to 72-fold and 520-fold more potent than MC and H-AZM, respectively. Me-AZM also demonstrated increased DNA modification over MC and H-AZM in alkaline COMET and Hoechst fluorescence assays that measured crosslinks in cellular DNA. Me-AZM and H-AZM treatment of Jurkat cells was found to sponsor significant DNA-protein crosslinks using …

Determinants Of Seat Belt Use: Regression Analysis With Fars Data Corrected For Self-Selection, Frank Goetzke, Samia Islam

Economics Faculty Publications and Presentations

We develop a methodology to use FARS data as an alternative to NOPUS in estimating seat belt usage. The advantages of using FARS over NOPUS are that (i) FARS is broader because it contains more variables relevant for policy analysis, (ii) FARS allows for easy multivariate regression analysis, and, finally, (iii) FARS data is more cost-effective. Methodology: We apply a binary logit model in our analysis to determine the likelihood of seat belt usage given various occupant, vehicle, and built environment characteristics. Using FARS data, we derive coefficient estimates for categories such as vehicle occupants' age and night time …

Young In Class: Implications For Inattentive/Hyperactive Behaviour Of Canadian Boys And Girls, Kelly Chen, Nicole Fortin, Shelley Phipps

Economics Faculty Publications and Presentations

Using data from the Statistics Canada National Longitudinal Survey of Children and Youth (NLSCY), this paper investigates the impact of school entry age on inattentive/hyperactive behaviours. We employ both a cross-provinces-time differences-in-differences approach, and a within-province regression discontinuity design. We find that being young in class causes greater inattentive/hyperactive behaviour, exacerbating any inattentive/hyperactive behavior exhibited prior to school entry. These results also also hold in sibling fixed effect models. Though we do not find gender differences in the effects, because boys are more likely to be inattentive/hyperactive at school entry, they are more affected. These effects persist into early adolescence.

Modeling Trade-Offs Between Plant Fiber And Toxins: A Framework For Quantifying Risks Perceived By Foraging Herbivores, Meghan J. Camp, Lisa A. Shipley, Timothy R. Johnson, Jennifer Sorenson Forbey, Janet L. Rachlow, Miranda M. Crowell

Biology Faculty Publications and Presentations

When selecting habitats, herbivores must weigh multiple risks, such as predation, starvation, toxicity, and thermal stress, forcing them to make fitness trade-offs. Here, we applied the method of paired comparisons (PC) to investigate how herbivores make trade-offs between habitat features that influence selection of food patches. The method of PC measures utility and the inverse of utility, relative risk, and makes trade-offs and indifferences explicit by forcing animals to make choices between two patches with different types of risks. Using a series of paired-choice experiments to titrate the equivalence curve and find the marginal rate of substitution for one risk …

Skills, Division Of Labor, And Economies Of Scale Among Amazonian Hunters And South Indian Honey Collectors, Paul L. Hooper, Kathryn Demps, Michael Gurven, Drew Gerkey, Hillard S. Kaplan

Anthropology Faculty Publications and Presentations

In foraging and other productive activities, individuals make choices regarding whether and with whom to cooperate, and in what capacities. The size and composition of cooperative groups can be understood as a self-organized outcome of these choices, which are made under local ecological and social constraints. This article describes a theoretical framework for explaining the size and composition of foraging groups based on three principles: (1) the sexual division of labor; (2) the intergenerational division of labor; and (3) economies of scale in production. We test predictions from the theory with data from two field contexts: Tsimane' game hunters of …

Leveraging It Resources, Embeddedness, And Dependence: A Supplier's Perspective On Appropriating Benefits With Powerful Buyers, Michael T. Lee, Kit Scott

Accountancy Faculty Publications and Presentations

The relationships between suppliers and buyers are often characterised by power differentials and dependence at the same time. This leads to the ability of a powerful buyer to benefit more from the relationship than the supplier. We examine how a supplier can strengthen its use of relation-specific IT with embeddedness to appropriate its share of relational benefits. We developed and tested a model of supplier relation-specific IT use, embeddedness, and buyer dependence on supplier. The results showed that embeddedness did not lead directly to the sharing of relational benefits; rather the appropriation of relational benefits is derived from buyer dependence.

Lower Bound For Ranks Of Invariant Forms, Harm Derksen, Zach Teitler

Mathematics Faculty Publications and Presentations

We give a lower bound for the Waring rank and cactus rank of forms that are invariant under an action of a connected algebraic group. We use this to improve the Ranestad-Schreyer-Shafiei lower bounds for the Waring ranks and cactus ranks of determinants of generic matrices, Pfaffians of generic skew-symmetric matrices, and determinants of generic symmetric matrices.

Data For Aboveground Biomass Estimates Of Sagebrush Using Terrestrial And Airborne Lidar Data In A Dryland Ecosystem, Aihua Li, Nancy F. Glenn, Peter J. Olsoy, Jessica J. Mitchell, Rupesh Shrestha

MILES Data Sets

Vegetation biomass estimates across drylands at regional scales are critical for ecological modeling, yet the low-lying and sparse plant communities characterizing these ecosystems are challenging to accurately quantify and measure their variability using spectral-based aerial and satellite remote sensing. To overcome these challenges, multi-scale data including field-measured biomass, terrestrial laser scanning (TLS) and airborne laser scanning (ALS) data, were combined in a hierarchical modeling framework. Data derived at each scale were used to validate an increasingly broader index of sagebrush (Artemisia tridentata) aboveground biomass. First, two automatic crown delineation methods were used to delineate individual shrubs across the TLS plots. …

Determining Hydrodynamic Forces In Bursting Bubbles Using Dna Nanotube Mechanics, Rizal F. Hariadi, Erik Winfree, Bernard Yurke

Materials Science and Engineering Faculty Publications and Presentations

Quantifying the mechanical forces produced by fluid flows within the ocean is critical to understanding the ocean’s environmental phenomena. Such forces may have been instrumental in the origin of life by driving a primitive form of self-replication through fragmentation. Among the intense sources of hydrodynamic shear encountered in the ocean are breaking waves and the bursting bubbles produced by such waves. On a microscopic scale, one expects the surface-tension–driven flows produced during bubble rupture to exhibit particularly high velocity gradients due to the small size scales and masses involved. However, little work has examined the strength of shear flow rates …

Homogeneous Cosmology With Aggressively Expanding Civilizations, S. Jay Olson

Physics Faculty Publications and Presentations

In the context of a homogeneous Universe, we note that the appearance of aggressively expanding advanced life is geometrically similar to the process of nucleation and bubble growth in a first-order cosmological phase transition. We exploit this similarity to describe the dynamics of life saturating the Universe on a cosmic scale, adapting the phase transition model to incorporate probability distributions of expansion and resource consumption strategies. Through a series of numerical solutions spanning several orders of magnitude in the input assumption parameters, the resulting cosmological model is used to address basic questions related to the intergalactic spreading of life, dealing …

An Immersed Boundary Geometric Preprocessor For Arbitrarily Complex Terrain And Geometry, Inanc Senocak, Micah Sandusky, Rey Deleon, Derek Wade, Kyle Felzien, Marianna Budnikova

Mechanical and Biomedical Engineering Faculty Publications and Presentations

There is a growing interest to apply the immersed boundary method to compute wind fields over arbitrarily complex terrain. The computer implementation of an immersed boundary module into an existing flow solver can be accomplished with minor modifications to the rest of the computer program. However, a versatile preprocessor is needed at the first place to extract the essential geometric information pertinent to the immersion of an arbitrarily complex terrain inside a 3D Cartesian mesh. Errors in the geometric information can negatively impact the correct implementation of the immersed boundary method as part of the solution algorithm. Additionally, the distance …

Serum Proteins Enhance Dispersion Stability And Influence The Cytotoxicity And Dosimetry Of Zno Nanoparticles In Suspension And Adherent Cancer Cell Models, Catherine B. Anders, Jordan J. Chess, Denise G. Wingett, Alex Punnoose

Biomolecular Research Center Publications and Presentations

Agglomeration and sedimentation of nanoparticles (NPs) within biological solutions is a major limitation in their use in many downstream applications. It has been proposed that serum proteins associate with the NP surface to form a protein corona that limits agglomeration and sedimentation. Here, we investigate the effect of fetal bovine serum (FBS) proteins on the dispersion stability, dosimetry, and NP-induced cytotoxicity of cationic zinc oxide nanoparticles (nZnO) synthesized via forced hydrolysis with a core size of 10 nm. Two different in vitro cell culture models, suspension and adherent, were evaluated by comparing a phosphate buffered saline (PBS) nZnO dispersion (nZnO/PBS) …

Dna-Mediated Excitonic Upconversion Fret Switching, Donald L. Kellis, Sarah M. Rehn, Brittany L. Cannon, Paul H. Davis, Elton Graugnard, Jeunghoon Lee, Bernard Yurke, William B. Knowlton

Materials Science and Engineering Faculty Publications and Presentations

Excitonics is a rapidly expanding field of nanophotonics in which the harvesting of photons, ensuing creation and transport of excitons via Förster resonant energy transfer (FRET), and subsequent charge separation or photon emission has led to the demonstration of excitonic wires, switches, Boolean logic and light harvesting antennas for many applications. FRET funnels excitons down an energy gradient resulting in energy loss with each step along the pathway. Conversely, excitonic energy upconversion via upconversion nanoparticles (UCNPs), although currently inefficient, serves as an energy ratchet to boost the exciton energy. Although FRET-based upconversion has been demonstrated, it suffers from low FRET …

A Cmos Spiking Neuron For Brain-Inspired Neural Networks With Resistive Synapses And In-Situ Learning, Xinyu Wu, Vishal Saxena, Kehan Zhu, Sakkarapani Balagopal

Electrical and Computer Engineering Faculty Publications and Presentations

Nano-scale resistive memories are expected to fuel dense integration of electronic synapses for large-scale neuromorphic system. To realize such a brain-inspired computing chip, a compact CMOS spiking neuron that performs in-situ learning and computing while driving a large number of resistive synapses is desired. This work presents a novel leaky integrate-and-fire neuron design which implements the dual-mode operation of current integration and synaptic drive, with a single opamp and enables in-situ learning with crossbar resistive synapses. The proposed design was implemented in a 0.18μm CMOS 􀀃technology. Measurements show neuron’s ability to drive a thousand resistive synapses, and demonstrate an in-situ …

Streambed And Water Profile Response To In-Channel Restoration Structures In A Laboratory Meandering Stream, Bangshuai Han, Hong-Hanh Chu, Theodore A. Endreny

Geosciences Faculty Publications and Presentations

In-channel structures are often installed in alluvial rivers during restoration to steer currents, but they also modify the streambed morphology and water surface profile, and alter hydraulic gradients driving ecologically important hyporheic exchange. Although river features before and after restoration need to be compared, few studies have collected detailed observations to facilitate this comparison. We created a laboratory mobile-bed alluvial meandering river and collected detailed measurements in the highly sinuous meander before and after installation of in-channel structures, which included one cross vane and six J-hooks situated along 1 bar unit. Measurements of streambed and water surface elevation with sub-millimeter …

Reclaiming Lost Territory: The Response Of Owyhee Harvester Ants To Forager Intrusions By Neighboring Colonies, Brett D. Howell, Ian C. Robertson

Biology Faculty Publications and Presentations

Neighboring colonies of the Owyhee harvester ant, Pogonomyrmex salinus, often share nonoverlapping foraging boundaries in the areas between their nests. We found that interactions between neighbors along these foraging boundaries were infrequent but peaceful, and usually resulted in one or both individuals becoming agitated and scurrying away in opposite directions. Interactions between neighbors were necessary to maintain the foraging ranges of their respective colonies. An exclusion experiment showed that when one colony of a pair situated 5-7 m apart was denied access to its foraging range, individuals from the other colony would usually (i.e., in 7 out of 10 cases) …

The Decision, Implementation And Assessment Of A Credit-Bearing Activity Class By Faculty In Residence: A Case Study, Janet Callahan, Geoff Harrison, Michael Humphrey, Cala Sielaff, Melissa Wintrow
