Long-Term Impact Of Poultry Manure On Crop Yield, Soil And Water Quality, And Crop Revenue, Natasha L. Hoover, Ji Yeow Law, Leigh Ann M. Long, Rameshwar S. Kanwar, Michelle L. Soupir Dec 2019

Long-Term Impact Of Poultry Manure On Crop Yield, Soil And Water Quality, And Crop Revenue, Natasha L. Hoover, Ji Yeow Law, Leigh Ann M. Long, Rameshwar S. Kanwar, Michelle L. Soupir

Agricultural and Biosystems Engineering Publications

A long-term poultry manure fertilizer study was initiated in 1998 and continued until 2009 under corn-soybean (CS) rotation. To match changing landscape trends, the plots were switched to continuous corn (CC) from 2010 to 2017. In both CS and CC phases, poultry manure (PM) was applied at the crop rotation recommended agronomic N rate and either half (CC phase) or double (CS phase) the recommended rate. Urea-ammonium nitrate (UAN) was applied to comparison plots at the crop recommended application rate (168 kg N ha−1 and 224 kg N ha−1 for the CS and CC phases, respectively) throughout the ...


A Question Of Trust: Can We Build An Evidence Base To Gain Trust In Systematic Review Automation Technologies?, Annette M. O'Connor, Guy Tsafnat, James Thomas, Paul Glasziou, Stephen B. Gilbert, Brian Hutton Dec 2019

A Question Of Trust: Can We Build An Evidence Base To Gain Trust In Systematic Review Automation Technologies?, Annette M. O'Connor, Guy Tsafnat, James Thomas, Paul Glasziou, Stephen B. Gilbert, Brian Hutton

Industrial and Manufacturing Systems Engineering Publications

Background Although many aspects of systematic reviews use computational tools, systematic reviewers have been reluctant to adopt machine learning tools.

Discussion We discuss that the potential reason for the slow adoption of machine learning tools into systematic reviews is multifactorial. We focus on the current absence of trust in automation and set-up challenges as major barriers to adoption. It is important that reviews produced using automation tools are considered non-inferior or superior to current practice. However, this standard will likely not be sufficient to lead to widespread adoption. As with many technologies, it is important that reviewers see “others” in ...

Agronomy Publications

Sustainable agriculture describes crop management approaches that address the interdependent goals of increasing or at least maintaining yield while protecting the environment, conserving natural resources, and slowing climate change. Numerous authors have espoused limiting synthetic fertilizer and pesticides and promoting organic agriculture (Lechenet et al., 2014; Martinez-Alcantara et al., 2016; Muller at al. 2017), less meat consumption (West et al., 2014; Poore and Nemecek, 2018; Springmann et al., 2018), or combinations of these strategies as viable solutions to achieve those goals, thereby improving agricultural sustainability.


Dynamic Reserves In Matching Markets, Orhan Aygün, Bertan Turhan Sep 2019

Dynamic Reserves In Matching Markets, Orhan Aygün, Bertan Turhan

Economics Working Papers

We study a school choice problem under affirmative action policies where authorities reserve a certain fraction of the slots at each school for specific student groups, and where students have preferences not only over the schools they are matched to but also the type of slots they receive. Such reservation policies might cause waste in instances of low student demand from some student groups. To propose a solution to this issue, we construct a family of choice functions, dynamic reserves choice functions, for schools that respect within-group fairness and allow the transfer of otherwise vacant slots from low-demand groups to ...


Repetitive Finger Movement And Circle Drawing In Persons With Parkinson’S Disease, Elizabeth L. Stegemoller, Andrew Zaman, Jennifer Uzochukwu Sep 2019

Repetitive Finger Movement And Circle Drawing In Persons With Parkinson’S Disease, Elizabeth L. Stegemoller, Andrew Zaman, Jennifer Uzochukwu

Kinesiology Publications

Little is known regarding how repetitive finger movement performance impacts other fine motor control tasks, such as circle drawing, in persons with Parkinson’s disease (PD). Previous research has shown that impairments in repetitive finger movements emerge at rates near to and above 2 Hz in most persons with PD. Thus, the purpose of this study was to compare circle drawing performance in persons with PD that demonstrate impairment in repetitive finger movement and those that do not. Twenty-two participants with PD and twelve healthy older adults completed the study. Only participants with PD completed the repetitive finger movement task ...

A complete 8-bus ERCOT test case is developed and implemented to illustrate the capabilities of the test ...


Identifying Marginal Treatment Effects In The Presence Of Sample Selection, Otávio Bartalotti, Desire Kedagni, Vitor Possebom Sep 2019

Identifying Marginal Treatment Effects In The Presence Of Sample Selection, Otávio Bartalotti, Desire Kedagni, Vitor Possebom

Economics Working Papers

This article presents identification results for the marginal treatment effect (MTE) when there is sample selection. We show that the MTE is partially identified for individuals who are always observed regardless of treatment, and we derive sharp bounds on this parameter under four sets of assumptions. The first identification result combines the standard MTE assumptions without any restrictions to the sample selection mechanism. The second result imposes monotonicity of the sample selection variable with respect to the treatment, considerably shrinking the identified set. Third, we incorporate a stochastic dominance assumption which tightens the lower bound for the MTE. Finally, we ...


Self-Determination Through Circus Arts: Exploring Youth Development In A Novel Activity Context, Jennifer P. Agans, Jacqueline L. Davis, Spyridoula Vazou, Tal Jarus Sep 2019

Self-Determination Through Circus Arts: Exploring Youth Development In A Novel Activity Context, Jennifer P. Agans, Jacqueline L. Davis, Spyridoula Vazou, Tal Jarus

Kinesiology Publications

Youth development takes place in many contexts, with different resulting participant outcomes. Broadening the scope of research to include non-traditional contexts such as youth circus arts programs, which are both similar to and different from other out-of-school-time contexts, may promote better understanding of the ways in which these programs impact youth development. The present study examined the prevalence of support for basic psychological needs and positive developmental outcomes among youth circus program participants. Single time-point quantitative surveys were completed by 111 youth members of the American Youth Circus Organization (62% female), ranging in age from 10 to 21. Results indicated ...


Extension Demonstration: Grameen Microfinance Methods And Capital Access For Low-Income Female Entrepreneurs, Mark A. Edelman Sep 2019

Extension Demonstration: Grameen Microfinance Methods And Capital Access For Low-Income Female Entrepreneurs, Mark A. Edelman

Economics Working Papers

A nonprofit community development financial institution and Extension collaborated to conduct a demonstration project to evaluate efficacy of Grameen peer-group microfinance methodology in addressing barriers faced by lowincome women entrepreneurs in a small metro area. Program performance metrics achieved by 284 low-income, culturally diverse, primarily women entrepreneurs over five years included: a loan repayment rate of 99+ percent, increased average client income, savings accumulation at a local bank, and increased opportunities to improve average credit scores. Client surveys indicated peer-group methods, program structure, incentives for individual behaviors and group responsibilities provided opportunity to develop confidence, leadership skills, and teamwork.


Uncivil Agreement: How Politics Became Our Identity Lilliana Mason, Chicago: University Of Chicago Press, 2018, Pp. 192., David A. M. Peterson Sep 2019

Uncivil Agreement: How Politics Became Our Identity Lilliana Mason, Chicago: University Of Chicago Press, 2018, Pp. 192., David A. M. Peterson

Political Science Publications

Lilliana Mason's Uncivil Agreement: How Politics Became Our Identity is easily the best book on American politics I have read in years. I mean this in two important ways. First, the book tackles what may be the most pressing question in politics: Why has the American public become increasing polarized? The answer—that the increasing overlap between identities changes the way that citizens see themselves and others—provides a clear understanding of polarization. But this is not only an important book, it is a good book. Mason constructs a careful argument, grounded in social psychology, and each chapter in ...


Long-Run Impacts Of Trade Shocks And Export Competitiveness: Evidence From The U.S. Bse Event, Chen-Ti Chen, John M. Crespi, William Hahn, Lee L. Schulz, Fawzi Taha Sep 2019

Long-Run Impacts Of Trade Shocks And Export Competitiveness: Evidence From The U.S. Bse Event, Chen-Ti Chen, John M. Crespi, William Hahn, Lee L. Schulz, Fawzi Taha

CARD Working Papers

This paper examines how comparative advantages of major beef exporters changed following the 2003 bovine spongiform encephalopathy outbreak (BSE), which significantly disrupted the U.S. beef trade until approximately April 2007. Using longitudinal data on beef export values and constructed revealed comparative advantage measures, we show that while some measure of the long-run impacts of BSE on U.S. beef export competitiveness have returned to pre-2003 levels, the U.S.’s comparative advantage has not. We also examine a hypothetical scenario of no BSE event in 2003 and predict what exporters’ competitiveness would have looked like. The authors discuss the ...


Why Do They Sew? Women’S Motivations To Sew Clothing For Themselves, Addie Martindale, Ellen C. Mckinney Aug 2019

Why Do They Sew? Women’S Motivations To Sew Clothing For Themselves, Addie Martindale, Ellen C. Mckinney

Apparel, Events and Hospitality Management Publications

Garment sewing is undergoing a resurgence in participation, with a growing number of women choosing to sew their clothing instead of buying readily available fast fashion. The purpose of this qualitative study was to understand the current motivations of an ethnically diverse sample of women who sew garments for themselves. The in-depth interview data from 15 interviews revealed personal fulfillment to be the overarching reason for participation. Personal fulfillment was achieved through main emergent themes of investment, control, and empowerment with 10 subthemes. Theoretical perspectives of prosumerism, craft and do-it-yourself consumption, and uses and gratification theory were applied to the ...


Property Rights And The Efficient Extraction Of Common Pool Resources: Evidence From West Coast Groundfish, Keith S. Evans, Carl Lian, Quinn Weninger Aug 2019

Property Rights And The Efficient Extraction Of Common Pool Resources: Evidence From West Coast Groundfish, Keith S. Evans, Carl Lian, Quinn Weninger

Economics Working Papers

Evaluating efficiency gains from adopting property rights-based fisheries management is data intensive, complicated by delays in adjusting to economic incentives implicit in output control regulations, and potentially confounded by the effects of changing stock abundance and other fundamentals. This paper evaluates harvesting efficiency for the universe of vessel participants in the West Coast groundfish trawl fishery two years prior to and six years following introduction of individual fishing quota (IFQ) regulations. Our methods control for delayed fleet restructuring and confounding effects of changing groundfish stock abundance. We find that under IFQs, redundant vessel capital exited the groundfish fishery at a ...


The Exports Of Higher Education Services From Oecd Countries To Asian Countries. A Gravity Approach, John C. Beghin, Byung Yul Park Aug 2019

The Exports Of Higher Education Services From Oecd Countries To Asian Countries. A Gravity Approach, John C. Beghin, Byung Yul Park

Economics Working Papers

We analyze bilateral exports of higher education services between OECD countries and Asia, using a gravity equation approach, panel data from 1998 to 2016, and PPML regression. The approach treats higher education consumption by Asian countries as a consumable durable good. Asian Students come to OECD countries to obtain degrees from their universities. Structurally, the flow of students from Asian country j to OECD country i depends on bilateral transaction costs between i and j, the income per capita in j, school-age demographics in j, the higher-education capacity of i, the perceived quality of universities in i, and the usual ...

Efficacy Of Shoes And Boots In Preventing Motorcycle-Related Ankle Inversion., Justin T. Wilder, Mitchell L. Stephenson, Jason C. Gillette Jul 2019

Efficacy Of Shoes And Boots In Preventing Motorcycle-Related Ankle Inversion., Justin T. Wilder, Mitchell L. Stephenson, Jason C. Gillette

Kinesiology Presentations, Posters and Proceedings

The current investigation explored the potential prophylactic effects of shoes, work boots, and motorcycle boots in reducing ankle inversion associated with ankle sprain. While the majority of previous research has investigated the effects of protective equipment in crashes, rates of lower extremity loading in emergency stop contexts are comparable to jump landings and may induce frontal plane loading that could lead to ankle injury. Fifteen adults wore athletic shoes, work boots, and motorcycle boots in a motorcycle drop task. Motorcycle boots significantly (p = 0.03) decreased peak ankle inversion angles by 3.6 degrees, but also increased (p < 0.01) vertical ground reaction forces by 0.21 bodyweights compared to the other shod conditions. Overall, it is suggested that motorcycle boots can potentially protect motorcycle riders from both crash-based and emergency-stop injuries.


Multivariate Temporal Modeling Of Crime With Dynamic Linear Models, Nathaniel Garton, Jarad Niemi Jul 2019

Multivariate Temporal Modeling Of Crime With Dynamic Linear Models, Nathaniel Garton, Jarad Niemi

Statistics Publications

Interest in modeling contemporary crime trends, a task that has historically been considered valuable to the public, researchers, and policymakers, is resurging. Advancements in criminology have made it clear that understanding crime trends necessarily involves understanding trends in how likely individuals are to report crimes to the police, as well as how likely the police are to accurately record those crimes. In this paper, we use dynamic linear models to simultaneously model the time series for several crime types in order to gain insight into trends in crime and crime reporting. We analyze crime data from Chicago spanning 2007 through ...


Information Order In Monotone Decision Problems Under Uncertainty, Jian Li, Junjie Zhou Jul 2019

Information Order In Monotone Decision Problems Under Uncertainty, Jian Li, Junjie Zhou

Economics Working Papers

This paper examines the robustness of Lehmann’s ranking of experiments (Lehmann, 1988) for decisionmakers who are uncertainty-averse à la Cerreia- Vioglio et al. (2011). We show that, assuming commitment, for all uncertaintyaverse indices satisfying some mild assumptions, Lehmann’s informativeness ranking is equivalent to the induced uncertainty-averse value ranking of experiments for all agents with single-crossing vNM utility indices (Theorem 1). Moreover, Lehmann ranking can also be detected by varying the uncertainty-averse indices for a fixed finite collection of vNM utility indices (Theorem 2). Our findings suggest that Lehmann’s ranking can be a useful enrichment of Blackwell’s ...

Positive Affective And Behavioral Gains Of First-Year Students In Course-Based Research Across Disciplines, Elizabeth Sandquist, Cinzia Cervato, Craig Ogilvie

Geological and Atmospheric Sciences Publications

The Freshmen Research Initiative at Iowa State University promotes student interest and retention in science through introductory course-based undergraduate research experiences (CUREs). Successful strategies for the implementation of CUREs on a large scale in an affordable manner included the use of a postdoctoral coordinator and affiliation with student learning communities. Across multiple disciplines, students in single-semester introductory research courses reported personal gains related to research, to thinking and working like scientists, to attitudes and behaviors of a scientist, and to gains in skills as reported on the Undergraduate Research Student Self-Assessment. Key outcomes related to persistence in STEM, including self-efficacy ...


Matching With Generalized Lexicographic Choice Rules, Orhan Aygün, Bertan Turhan Jul 2019

Matching With Generalized Lexicographic Choice Rules, Orhan Aygün, Bertan Turhan

Economics Working Papers

Motivated by the need for real-world matching problems, this paper formulates a large class of practical choice rules, Generalized Lexicographic Choice Rules (GLCR), for institutions that consist of multiple divisions. Institutions fill their divisions sequentially, and each division is endowed with a sub-choice rule that satisfies classical substitutability and size monotonicity in conjunction with a new property that we introduce, quota monotonicity. We allow rich interactions between divisions in the form of capacity transfers. The overall choice rule of an institution is defined as the union of the sub-choices of its divisions. The cumulative offer mechanism (COM) with respect to ...


A Transactive Energy Approach To Distribution System Design: Household Formulation, Swathi Battula, Leigh Tesfatsion, Zhaoyu Wang Jun 2019

A Transactive Energy Approach To Distribution System Design: Household Formulation, Swathi Battula, Leigh Tesfatsion, Zhaoyu Wang

Economics Working Papers

A household model is formulated to facilitate careful performance testing of bid-based transactive energy system (TES) designs in advance of deployment. Household welfare is expressed by comfort minus cost. Household thermal dynamics are represented by an Equivalent Thermal Parameter (ETP) model based on appliance and house attributes. An optimal bid function is characterized for the household, conditional on its operating state. A method is developed for explicit derivation of this optimal bid function, given discretized forms for the household’s welfare and thermal dynamic functions. A method is also developed for constructing representative household types as correlated collections of welfare ...


Housing Recovery Through Social Capital: Puerto Rico After Hurricane Maria, Jessica Talbot, Cristina Poleacovschi, Sara Hamideh, Carlos S. Rivera Jun 2019

Housing Recovery Through Social Capital: Puerto Rico After Hurricane Maria, Jessica Talbot, Cristina Poleacovschi, Sara Hamideh, Carlos S. Rivera

Community and Regional Planning Proceedings, Papers, and Posters

Puerto Rico was devastated by Hurricane Maria on September 20, 2017. Due to a delayed and insufficient official response from the local and federal governments and other aid agencies, the effects are still crippling more than a year after the event. When official response networks failed, communities often engaged in informal reconstruction processes to facilitate their recovery. This research seeks to explain why certain communities were effective in reconstructing on their own and uses social capital theory as the theoretical framework. This study was conducted in four municipalities in Puerto Rico (Adjuntas, Barranquitas, Loíza, and Utuado). A mixed methods approach ...


Shoulder Muscular Fatigue From Static Posture Concurrently Reduces Cognitive Attentional Resources, Mitchell L. Stephenson, Alec G. Ostrander, Hamid Norasi, Michael C. Dorneich Jun 2019

Shoulder Muscular Fatigue From Static Posture Concurrently Reduces Cognitive Attentional Resources, Mitchell L. Stephenson, Alec G. Ostrander, Hamid Norasi, Michael C. Dorneich

Industrial and Manufacturing Systems Engineering Publications

Objective: The goal of this work is to determine whether muscular fatigue concurrently reduces cognitive attentional resources in technical tasks for healthy adults.

Background: Muscular fatigue is common in the workplace but often dissociated with cognitive performance. A corpus of literature demonstrates a link between muscular fatigue and cognitive function, but few investigations demonstrate that the instigation of the former degrades the latter in a way that may affect technical task completion. For example, laparoscopic surgery increases muscular fatigue, which may risk attentional capacity reduction and undermine surgical outcomes.

Method: A total of 26 healthy participants completed a dual-task cognitive ...


Ill Communication: Analyzing Five Years Of Iowa State University’S Print Interlibrary Loan Requests, Eric Schares Jun 2019

Ill Communication: Analyzing Five Years Of Iowa State University’S Print Interlibrary Loan Requests, Eric Schares

Reference and Instruction Conference Papers, Posters and Presentations

Interlibrary Loan (ILL) is a service offered by libraries to supply patrons with materials which are not immediately available for lending. This could be for many reasons; the library might not own the item, the library may own a copy but it is already checked out to another patron, or the assignment of a required but expensive textbook spurs high demand for a particular title.

Identification Of Treatment Effects With Mismeasured Imperfect Instruments, Desire Kedagni Jun 2019

Identification Of Treatment Effects With Mismeasured Imperfect Instruments, Desire Kedagni

Economics Working Papers

In this article, I develop a novel identification result for estimating the effect of an endogenous treatment using a proxy of an unobserved imperfect instrument. I show that the potential outcomes distributions are partially identified for the compliers. Therefore, I derive sharp bounds on the local average treatment effect. I write the identified set in the form of conditional moments inequalities, which can be implemented using existing inferential methods. I illustrate my methodology on the National Longitudinal Survey of Youth 1979 to evaluate the returns to college attendance using tuition as a proxy of the true cost of going to ...

The purpose of this study is to present, in careful comprehensive form, a complete analytical state-space control representation for a version of the GLD Household Equivalent Thermal Parameter Model as support documentation for model users. This model is a physically-based implementation of a household with multiple price-responsive and conventional appliances whose thermal dynamics are determined over successive days by resident appliance usage and external weather ...


What Drives Landowners’ Conservation Decisions? Evidence From Iowa, Wendiam Sawadgo, Wendong Zhang, Alejandro Plastina May 2019

What Drives Landowners’ Conservation Decisions? Evidence From Iowa, Wendiam Sawadgo, Wendong Zhang, Alejandro Plastina

Economics Working Papers

Conservation practices such as no-till and cover crops have been shown to have on-and off-farm benefits. However, underinvestment may occur when benefits of a practice do not go to the provider. A commonly cited barrier to conservation-practice adoption in agriculture is farmland-rental arrangements where tenants may not reap the benefits of conservation investments, resulting in lower adoption rates on leased land than on owner-operated fields. This issue is especially important since more than 40% of US farmland and more than half of Midwestern farmland is now rented from others. This paper examines the factors driving landowners’ decisions to adopt four ...
