The Devil In The Tiers, Robin C. Feldman
The Devil In The Tiers, Robin C. Feldman
Faculty Scholarship
Prescription drug spending in the USA has soared, fueled by rising drug prices. A critical mechanism for restraining drug prices is the formulary tiering system. Although tiering should reflect the cost of a drug—and reward patients who choose less-expensive drugs—something is seriously amiss. Using Medicare claims data from roughly one million patients between 2010 and 2017, this article finds troubling amounts of distorted tiering and wasted cost. Increasingly, generics are shifted to more expensive—and therefore less accessible—tiers. The percentage of generics on the leastexpensive tier drops from 73% to 28%; the percentage of drugs on inappropriate tiers rises from 47% …
Physicians Treating Alzheimer’S Disease Patients Should Be Aware That Televised Direct-To-Consumer Advertising Links More Strongly To Drug Utilization In Older Patients, Robin C. Feldman
Faculty Scholarship
Background: US direct-to-consumer advertising spending for medicine has soared in recent decades. Advertising has been shown to impact drug utilization. Most Alzheimer’s disease patients are above age 65 and may take a range of prescription medications for various disease states. Objective: To investigate how direct-to-consumer advertising is associated with the drug utilization of patients ≥ 65 years old. Methods: Using advertising expenditure data and Medicare Part D drug purchase claims, we performed regression analyses for each of the highest-spending drugs and age group, with cumulative monthly spending as the predictor variable and drug utilization as the response variable. For each …

Radical Response: Effects Of Heat Stress-Induced Oxidative Stress On Lipid Metabolism In The Avian Liver, Nima K. Emami, Usuk Jung, Brynn Voy, Sami Dridi
Poultry Science Faculty Publications and Presentations
Lipid metabolism in avian species places unique demands on the liver in comparison to most mammals. The avian liver synthesizes the vast majority of fatty acids that provide energy and support cell membrane synthesis throughout the bird. Egg production intensifies demands to the liver as hepatic lipids are needed to create the yolk. The enzymatic reactions that underlie de novo lipogenesis are energetically demanding and require a precise balance of vitamins and cofactors to proceed efficiently. External stressors such as overnutrition or nutrient deficiency can disrupt this balance and compromise the liver’s ability to support metabolic needs. Heat stress is …

Poultry Science Faculty Publications and Presentations
In an effort to understand the apparent trade-off between the continual push for growth performance and the recent emergence of muscle pathologies, shotgun proteomics was conducted on breast muscle obtained at similar to 8 weeks from commercial broilers with wooden breast (WB) myopathy and compared with that in pedigree male (PedM) broilers exhibiting high feed efficiency (FE). Comparison of the two proteomic datasets was facilitated using the overlay function of Ingenuity Pathway Analysis (IPA) (Qiagen, CA, USA). We focused on upstream regulator analysis and disease-function analysis that provides predictions of activation or inhibition of molecules based on (a) expression of …

We carried out a qualitative investigation of a pioneer of the Industrial Internet of Things operating in Silicon Valley since 1989. We reconstructed a sequence of strategic turns and conceptualized their current business model in a way that is relevant for several other industries enabled by the Internet, generalizing Thompson’s concept of mediating technologies in order to adapt it to contemporary, knowledge-based economies. We propose an interpretive framework for mediating technologies that we express by means of semantic networks.

Let A be a nontrivial abelian group. A connected simple graph G = (V, E) is A-antimagic, if there exists an edge labeling f: E(G) → A\{0A} such that the induced vertex labeling f+(v) = Σ{u,v} ∈ E(G) f({u,v}) is a one-to-one map. The integer-antimagic spectrum of a graph G is the set IAM(G) = {k: G is Zk-antimagic and k ≥ 2}. In this paper, we determine the integer-antimagic spectra for all Hamiltonian graphs.

Faculty Research, Scholarly, and Creative Activity
Survival data often include a fraction of units that are susceptible to an event of interest as well as a fraction of “immune” units. In many applications, spatial clustering in unobserved risk factors across nearby units can also affect their survival rates and odds of becoming immune. To address these methodological challenges, this article introduces our BayesSPsurv R-package, which fits parametric Bayesian Spatial split-population survival (cure) models that can account for spatial autocorrelation in both subpopulations of the user 's time-to-event data. Spatial autocorrelation is modeled with spatially weighted frailties, which are estimated using a conditionally autoregressive prior. The user …

Using a dis/ability critical race theory (DisCrit) and critical quantitative (QuantCrit) lens, we examine disproportionate application of exclusionary discipline on multiply marginalized youth, foregrounding systemic injustice and institutionalized racism. In doing so, we examined temporal-, student-, and school-level factors that may result in exclusion and othering (i.e., placing into special education and punishing with out-of-school suspensions) within one school district. We frame this study in DisCrit and QuantCrit frameworks to connect data-based decision making to sociocultural understandings of the ways in which schools use both special education and discipline to simultaneously provide and limit opportunities for different student groups. Results …

Prior work exploring preschool-aged children’s reasoning with repeating patterns has shown that patterning ability is an important predictor of math achievement; however, there is limited research exploring older children’s growing pattern task performance. The current study tested whether presentation format impacts performance on growing pattern problems, and whether the effects of presentation format extend to transfer word problems for which no patterns are provided. Sixth grade students were randomly assigned to complete several growing pattern tasks in one of three presentation formats (figures, sequences of values, or tables of values), and later completed transfer story problems with no figures, sequences, …

Over the years, rampant wildfires have plagued the state of California, creating economic and environmental loss. In 2018, wildfires cost nearly 800 million dollars in economic loss and claimed more than 100 lives in California. Over 1.6 million acres of land has burned and caused large sums of environmental damage. Although, recently, researchers have introduced machine learning models and algorithms in predicting the wildfire risks, these results focused on special perspectives and were restricted to a limited number of data parameters. In this paper, we have proposed two data-driven machine learning approaches based on random forest models to predict the …

We define a total k-labeling (Formula presented.) of a graph G as a combination of an edge labeling (Formula presented.) and a vertex labeling (Formula presented.) such that (Formula presented.) if (Formula presented.) and (Formula presented.) if (Formula presented.) where (Formula presented.) The total k-labeling (Formula presented.) is called an edge irregular reflexive k-labeling of G if every two different edges has distinct edge weights, where the edge weight is defined as the summation of the edge label itself and its two vertex labels. Thus, the smallest value of k for which the graph G has the edge irregular reflexive …

Faculty Research, Scholarly, and Creative Activity
Saturation problems for forbidden graphs have been a popular area of research for many decades, and recently Brualdi and Cao initiated the study of a saturation problem for 0-1 matrices. We say that a 0-1 matrix A is saturating for the forbidden 0-1 matrix P if A avoids P but changing any zero to a one in A creates a copy of P . Define sat(n, P ) to be the minimum possible number of ones in an n × n 0-1 matrix that is saturating for P . Fulek and Keszegh proved that for every 0-1 matrix P, either …

A Deweyan Approach To The Dilemma Of Everyday Aesthetics, Thomas Leddy
Faculty Research, Scholarly, and Creative Activity
Everyday aesthetics is a new sub-discipline of aesthetic theory that has only been actively discussed since the 1980s. This paper addresses what many consider the central issue of the field, called "the dilemma of everyday aesthetics." I discuss three authors who address this issue: Yuriko Saito, Allen Carlson, and Paisley Livingston. Drawing on Dewey's anti-dualist stance, I argued for a continuity between the aesthetics of everyday life and the aesthetics of art. In course of my discussion, I question such dichotomies as that between the practical and the aesthetic, the ordinary and the extraordinary, and disinterestedness vs. engagement. In my …

Let A be a nontrival abelian group. A connected simple graph G = (V, E) is Aantimagic if there exists an edge labeling f : E(G) → A \ {0} such that the induced vertex labeling f+ : V (G) → A, defined by f+(v) = Puv∈E(G) f(uv), is injective. The integer-antimagic spectrum of a graph G is the set IAM(G) = {k | G is Zk-antimagic and k ≥ 2}. In this paper, we determine the integer-antimagic spectra for cycles with a chord, paths with a chord, and wheels with a chord.

Ride-hailing services such as Lyft and Uber can complement rides offered by family, friends, paid providers, and public transit. To learn why older adults might wish to use ride-hail, we conducted an online survey of 2,917 California respondents age 55 and older. Participants were asked whether they would value four features hypothesized to be benefits of ride-hailing. We specified binary logit models and used market segmentation to investigate whether there were location-based differences in the use of ride-hailing. Our analysis showed that women, city dwellers, persons with disabilities, and those who rely on others for rides were more open to …

Despite the increasing frequency and magnitude of extreme climate events, little is known about how their impacts flow through social and ecological systems or whether management actions can dampen deleterious effects. We examined how the record 2014-2016 Northeast Pacific marine heatwave influenced trade-offs in managing conflict between conservation goals and human activities using a case study on large whale entanglements in the U.S. west coast's most lucrative fishery (the Dungeness crab fishery). We showed that this extreme climate event diminished the power of multiple management strategies to resolve trade-offs between entanglement risk and fishery revenue, transforming near win-win to clear …

Characterizing subcultural models of tap water derived from interviews from 154 respondents in four neighbourhoods in the urban Southwestern United States, we identify sources of public discourses that support and anticipate passive elite capture. In accord with predictions, social devaluation of those who use tap water is situated with residents of a privileged exclusive community sector. This suggests the value of a broader conceptualization and an empirical model of elite capture in water resources: not just as a physical deviation of resources, but also as a discursive devaluation of public resources by specifically elite populations.

This analysis focuses on different levels of Cross-Border Regional Planning (CBRP) processes in the Cascadia borderland. The region is home to the business-led initiative ‘Cascadia Innovation Corridor’ (CIC), designed to foster cross-border economic integration. The CIC strives to build a global innovation ecosystem in Cascadia, including a new high-speed train to connect Seattle and Vancouver. This paper focuses on the scope of the CIC as a CBRP case. The authors evaluate engagement of city governments and coherency between different planning scales to determine whether the CIC has been addressing the major challenges that may prevent tighter economicintegration in Cascadia.

This paper is a case study analysis of one student-faculty partnership working to enact departmental change. Students as Partners (SaP) is an approach in which students and faculty work in partnership on the co-design of a curricular or institutional change effort. Our team implements SaP through Departmental Action Teams (DATs), which are facilitated teams of faculty, students, and staff within a single STEM department working on an issue related to undergraduate education. In our research, we aim to understand the ways in which SaP becomes enacted in DATs. Through analyzing interviews with student and faculty members of a single DAT, …

Faculty Research, Scholarly, and Creative Activity
A variety of wildfire models are currently used for prescribed fire management, fire behaviour studies and decision support during wildfire emergencies, among other applications. All these applications are based on predictive analysis, and therefore require careful estimation of aleatoric and epistemic uncertainties such as weather conditions, vegetation properties and model parameters. However, the large computational cost of high-fidelity computaional fluid dynamics models prohibits the straightforward utilization of traditional Monte Carlo methods. Conversely, low-fidelity fire models are several orders of magnitude faster but they typically do not provide enough accuracy and they do not resolve all relevant phenomena. Multifidelity frameworks offer …

In recent years, there has been a florescence of cross-cultural research using ethnographic and qualitative data. This cutting-edge work confronts a range of significant methodological challenges, but has not yet addressed how thematic analysis can be modified for use in cross-cultural ethnography. Thematic analysis is widely used in qualitative and mixed-methods research, yet is not currently well-adapted to cross-cultural ethnographic designs. We build on existing thematic analysis techniques to discuss a method to inductively identify metathemes (defined here as themes that occur across cultures). Identifying metathemes in cross-cultural research is important because metathemes enable researchers to use systematic comparisons to …
