Welfare-Adjusted Life Years (Waly): A Novel Metric Of Animal Welfare That Combines The Impacts Of Impaired Welfare And Abbreviated Lifespan, Kendy Tzu-Yun Teng, Brecht Devleesschauwer, Charline Maerten De Noordhout, Peter Bennett, Paul Mcgreevy, Po-Yu Chiu, Jenny-Ann L.M.L. Toribio, Navneet Dhand

Paul McGreevy, Ph.D.

Currently, separate measures are used to estimate the impact of animal diseases on mortality and animal welfare. This article introduces a novel metric, the Welfare-Adjusted Life Year (WALY), to estimate disease impact by combining welfare compromise and premature death components. Adapting the Disability-Adjusted Life Year approach used in human health audits, we propose WALY as the sum of a) the years lived with impaired welfare due to a particular cause and b) the years of life lost due to the premature death from the same cause. The years lived with impaired welfare are the product of the average duration of ...


Work-Type Influences Perceived Livestock Herding Success In Australian Working Kelpies, Jonathan B. Early, Elizabeth R. Arnott, Lisa J. Mascord, Diane Van Rooy, Paul Mcgreevy, Claire M. Wade Jul 2019

Work-Type Influences Perceived Livestock Herding Success In Australian Working Kelpies, Jonathan B. Early, Elizabeth R. Arnott, Lisa J. Mascord, Diane Van Rooy, Paul Mcgreevy, Claire M. Wade

Paul McGreevy, Ph.D.

Background

Working dog handlers and breeders have very different behavioural requirements in the animals that they employ for managing livestock. The Australian Working Kelpie breed may be used in several working contexts, notably yards, paddocks and a combination of both. The working context influences the skillsets required and gives rise to three corresponding work-types: Yard, Paddock and Utility Kelpies. In particular, dogs used for working stock in the confines of yards and trucks interact with stock more forcefully than those mustering in larger areas (paddocks) where they can herd stock effectively from a greater distance. This article explores owner assessments ...

The influence of human harvest on evolution of secondary sexual characteristics has implications for sustainable management of wildlife populations. The phenotypic consequences of selectively removing males with large horns or antlers from ungulate populations has been a topic of heightened concern in recent years. Harvest can affect size of horn‐like structures in two ways: 1) shifting age structure toward younger age classes, which can reduce the mean size of horn‐like structures; or 2) selecting against genes that produce large, fast‐growing males. We evaluated effects of age, climatic and forage conditions, and metrics of harvest on horn size ...

The objective was to determine if cooking skills and meal planning behaviors are associated with greater fruit and vegetable intake and lower body mass index (BMI) in first-year college students who are at risk for excessive weight gain. A cross-sectional analysis was conducted using baseline data from a multi-state research project aimed at preventing weight gain in first-year college students. Cooking type, frequency and confidence, self-instruction for healthful mealtime behavior intention, self-regulation of healthful mealtime behavior, and cup equivalents of fruits and vegetables (FV) were measured using validated surveys. BMI was calculated from measured height and weight. First-year students (n ...

Qualitative Analysis Of Grocery Store And Farmers Market Manager Perceptions Regarding Use Of Fruit And Vegetable Educational Materials, Lacey Mccormack, Shelly Brandenburger, Karlys Wells, Suzanne Stluka

Lacey Arneson McCormack

The Pick it! Try it! Like it! (PTL) educational resource set, developed to display in grocery stores and farmers markets, teaches individuals how to shop for and prepare healthy fruit and vegetable dishes. Because program buy-in must be obtained from location managers before implementation occurs, the purpose of this study was to qualitatively examine the perceptions that grocery store and farmers market managers have regarding PTL implementation. Locations that requested PTL materials during 2013-14 were contacted and asked to answer 13 questions. Responses were analyzed using the content analysis method with themes generated and frequencies reported. Analyses examined manager perceptions ...

The objective was to describe the development process of a curriculum (iCook 4-H) targeted to low-income, rural, and/or diverse youths and their adult primary meal preparer to promote cooking, eating, and playing together. Lessons learned highlighted the importance of grounding the curriculum in Social Cognitive Theory and applying the experiential 4-H learning model using a multiphased, community-based participatory approach with cyclical development and evaluation, and key modifications made for dissemination and distribution. Findings across 4 testing phases over 6 years and 5 states demonstrated the time-intensive, cyclical process that required flexibility with fidelity to form a hands-on, interactive curriculum.

Measuring Sub-Second Wind Velocity Changes For Agricultural Drift One Meter Above The Ground, Matthew W. Schramm, H. Mark Hanna, Matthew J. Darr, Steven J. Hoff, Brian L. Steward Jul 2019

Measuring Sub-Second Wind Velocity Changes For Agricultural Drift One Meter Above The Ground, Matthew W. Schramm, H. Mark Hanna, Matthew J. Darr, Steven J. Hoff, Brian L. Steward

Brian L. Steward

Agricultural spray drift is affected by many factors including current weather conditions, topography of the surrounding area, fluid properties at the nozzle, and the height at which the spray is released. During the late spring/summer spray seasons of 2014 and 2015, wind direction, speed, and solar radiation (2014 only) were measured at 10 Hz, one meter above the ground to investigate conditions that are typically encountered by a droplet when released from a nozzle on an agricultural sprayer. Measurements of wind velocity as the wind passed from an upwind sensor to a downwind sensor were used to evaluate what ...

Tillage Implement Design And Its Effect On Soil, Mahdi Al-Kaisi, H. Mark Hanna, Michael Tidman

H. Mark Hanna

The weather is gradually improving and most Iowa producers are getting closer to working in the field. Some have already started fieldwork. However, there is still time to finalize preparation of tillage implements for spring fieldwork. Producers are encouraged to check and evaluate the design of soil-engaging components of their tillage implements, assess the potential for soil erosion, and think about their chances for a successful crop.

Tillage Equipment Maintenance, H. Mark Hanna, Mahdi Al-Kaisi, Michael J. Tidman

H. Mark Hanna

Many crop operations experience a lull in mid-winter. This lull is a great time to take a look at tillage equipment maintenance for the 2002 growing season and catch up on "little fixes" that were put off from last year. Proper setup and maintenance of tillage equipment can eliminate extra tillage trips through the field and increase equipment efficiency, which preserves crop residue and limits soil erosion.

Barriers And Motivators For Tractors Rops Retrofitting In Iowa, Charles V. Schwab, J. Gordon Arbuckle, H. Mark Hanna

H. Mark Hanna

Iowa State University Extension and Outreach conducted an assessment of Iowa farm operators’ perceptions about the barriers and motivators when considering retrofitting tractors with rollover protective structures (ROPS). A statewide sample of approximately 2,000 farm operators were surveyed in the 2017 Iowa Farm and Rural Life Poll. A series of questions were asked to evaluate the importance of potential barriers to decisions not to retrofit a tractor and potential motivators that could influence the decision to retrofit or purchase a tractor with ROPS. The survey received a 48% response rate with 999 responses. Among the 76% of Iowa farm ...

Physiological Integration Of Coral Colonies Is Correlated With Bleaching Resistance, Timothy D. Swain, Emily C. Bold, Phillip C. Osborn, Andrew H. Baird, Mark W. Westneat, Vadim Backman, Luisa A. Marcelino Jul 2019

Physiological Integration Of Coral Colonies Is Correlated With Bleaching Resistance, Timothy D. Swain, Emily C. Bold, Phillip C. Osborn, Andrew H. Baird, Mark W. Westneat, Vadim Backman, Luisa A. Marcelino

Timothy Swain

Inter-module physiological integration of colonial organisms can facilitate colony-wide coordinated responses to stimuli that strengthen colony fitness and stress resistance. In scleractinian corals, whose colonial integration ranges from isolated polyps to a seamless continuum of polyp structures and functions, this coordination improves responses to injury, predation, disease, and stress and may be one of the indications of an evolutionary origin of Symbiodinium symbiosis. However, observations of species-specific coral bleaching patterns suggest that highly integrated coral colonies may be more susceptible to thermal stress, and support the hypothesis that communication pathways between highly integrated polyps facilitate the dissemination of toxic byproducts ...

Timothy Swain

Background At the forefront of ecosystems adversely affected by climate change, coral reefs are sensitive to anomalously high temperatures which disassociate (bleaching) photosynthetic symbionts (Symbiodinium) from coral hosts and cause increasingly frequent and severe mass mortality events. Susceptibility to bleaching and mortality is variable among corals, and is determined by unknown proportions of environmental history and the synergy of Symbiodinium- and coral-specific properties. Symbiodinium live within host tissues overlaying the coral skeleton, which increases light availability through multiple light-scattering, forming one of the most efficient biological collectors of solar radiation. Light-transport in the upper ~200 μm layer of corals skeletons ...

Timothy Swain

Calcium carbonate skeletons of scleractinian corals amplify light availability to their algal symbionts by diffuse scattering, optimizing photosynthetic energy acquisition. However, the mechanism of scattering and its role in coral evolution and dissolution of algal symbioses during “bleaching” events are largely unknown. Here we show that differences in skeletal fractal architecture at nano/micro-lengthscales within 96 coral taxa result in an 8-fold variation in light-scattering and considerably alter the algal light environment. We identified a continuum of properties that fall between two extremes: (1) corals with low skeletal fractality that are efficient at transporting and redistributing light throughout the colony ...

Language Learning Under Classroom Conditions During The Transition To Hybrid Instruction: A Case-Study Of Student Performance During The Implementation Of Instructional Technology, Lisbeth O. Swain, Timothy D. Swain

Timothy Swain

We examined the unmanipulated performance of students under real classroom conditions in order to assess the effect of a technology-enhanced hybrid learning approach to second language, (L2) instruction on beginning and advanced Spanish language learners. This research focused on the transition period of technology implementation when the entire section of Spanish of a modern language department of a liberal arts university transitioned from traditional face-to-face instruction, to a technology-enhanced hybrid learning approach with concurrent reduction in face-to-face classroom hours. This implementation provided an opportunity to compare the performance of students prior to and during the transition to hybrid model of ...
