Farmer Participation In The Development And Implementation Of A New Technology: Introduction Of Lucerne (Medicago Sativa L.), A Perennial Legume, Into South-West Western Australia, L J. Blacklow, P Cocks

IGC Proceedings (1977-2023)

Australia since its demise due to insect attack in the 1970s. With new insect resistant varieties lucerne is once again becoming a viable pasture option for farmers. There is however, a slow rate of adoption of lucerne for a number of social and economic factors. The main limitations to the adoption of lucerne by farmers are past negative experience, farm systems dominated by annual pastures, changing wool and wheat commodity prices and perceived establishment and management difficulties. To overcome these socio-economic limitations a Model of Lucerne Adoption was developed in which the target group for the technology, the farmer, took …

Case Studies- A Useful Tool For Integrating Socio-Economic Data Into Grazing Systems Research, N D. Macleod

IGC Proceedings (1977-2023)

Grazing systems research and development (R&D) projects can provide important information on which to base management principles to integrate conservation management into grazing production systems. However, the adoption of these principles into practice remains largely unfulfilled. Most grazing experiments give limited attention to the socio-economic context of pastoral management. The paper suggests that one way of incorporating R&D findings and presenting them within a context that is more acceptable to decision-makers is via a case study approach. That is, use the considerable communication potential of the approach.

The Punctuated Arena Model- A New Approach To Tackling Technology Transfer Failure, N D. Macleod, A D. Shulman

IGC Proceedings (1977-2023)

Valuation of the worth of research and development activities is increasingly shifting from outputs to outcomes. The technology transfer record of agricultural R&D focused on pastures and resource management remains generally poor. Participatory R&D approaches have been developed and promoted to overcome this, but these also have performance problems. Based on the authors’ experience with R&D and communication management a Punctuated Arena Model has been developed which is argued to offer scope for improving technology transfer outcomes.

IGC Proceedings (1977-2023)

This experiment was conducted with the aim of studying whether the frequency and intensity of defoliation of the temperate grass fromental (Arrhenatherum elatius (L.) Presl.) affected its total dry matter (DM)/ha yield as well as the seasonal distribution of forage. Plots were seeded in 1988 and data collected from 1989 to 1991. Two frequencies and two intensities of defoliation were combined in a two factor randomized complete block design with six replications. Treatment plots were cut each year from early autumn to late spring. ANVA, Tukey and Dunnett tests were applied to find out differences between treatments and between …

Using Planned Volunteer Crabgrass (Digitaria Spp.) In Doublecropping With Cool Season Annual Forages, R L. Dalrymple

IGC Proceedings (1977-2023)

Crabgrass (Digitaria ciliaris Retz., D. sanguinalis (L.) Scop. and other species) is used as a real and planned forage. The major known use is in Oklahoma and about 19 other Southeast United States as a doublecropping or multicropping forage production approach whereby, crabgrass is the summer season forage and cool season annual grasses, with or without cool season legumes, are used as the winter season forage. High quality forage is thus produced up to over nine months of a year. Cereal rye (Secale cereale L.) and crabgrass doublecropping has produced up to over 10,000 pounds of grass per acre. Both …

Pipeline Reclamation Using Native Species, C Nykoluk

IGC Proceedings (1977-2023)

One of the oil and gas industry's challenges is to reclaim disturbed native rangeland with native species. In fall 1992, TransGas (a subsidiary of SaskEnergy) constructed a natural gas transmission line across the Coalfields Prairie Farm Rehabilitation Administration (PFRA) Community Pasture. This necessitated a 10 kilometre long - 18 metre wide right of way. The right of way was successfully reclaimed using a variety of reclamation techniques with the use of a native grass cultivar seed mix that approximated the vegetation composition of the pasture. This poster provides an example of how agencies with different goals can work together at …

Active And Retroactive Digital Newspaper Preservation, Andrew Mcdonnell

Library Faculty and Staff Publications

The University of Kentucky Libraries’ (UKL) long-running efforts to document and provide access to the state’s history via newspaper preservation have necessarily evolved over the last 80 years. As news formats and preservation technologies have changed, particularly in relation to born-digital media, the libraries’ efforts have had to keep pace. The race to preserve these materials before they disappear or are locked away on media inaccessible to modern computers is not always chronologically linear, though. Digital archivists and librarians must sometimes straddle multiple generations of technology to successfully migrate, capture, and otherwise preserve digital publications, and there is no single …

Working Well With Statisticians, Ryan A. Peterson, Emily Slade, Gina Maria Pomann, Walter T. Ambrosius

Biostatistics Faculty Publications

Statistical collaboration requires statisticians to work and communicate effectively with nonstatisticians, which can be challenging for many reasons. To identify common themes and lessons for working smoothly with nonstatistician collaborators, two focus groups of primarily academic collaborative statisticians were held. We identified qualities of collaborations that tend to yield fruitful relationships and those that tend to yield nothing (or worse, with one or both parties being dissatisfied). The initial goal was to share helpful knowledge and individual experiences that can facilitate more successful collaborative relationships for statisticians who work within academic statistical collaboration units. These findings were used to design …

Entomology Faculty Publications

Organic cucurbit growers face many challenges to production including insect pests, insect-vectored diseases, and non-vectored diseases. While Organic Material Review Institute (OMRI) -listed pesticides underperform at suppressing pests and diseases, some alternative pest management strategies hold promise, but little research exists on their cost-effectiveness. We compared the efficacy of mesotunnel systems (nylon-mesh netting row covers deployed over bent metal hoops) and OMRI-listed pesticides (fungicides and insecticides) on acorn squash across 2 years. During the early part of the season, before row covers were removed for pollination, we found 1.7 (2020) and 0.3 (2021) times more cucumber beetles in the uncovered …

Single-Cell Analysis Identifies Plk1 As A Driver Of Immunosuppressive Tumor Microenvironment In Luad, Yifan Kong, Chaohao Li, Jinpeng Liu, Sai Wu

Markey Cancer Center Faculty Publications

PLK1 (Polo-like kinase 1) plays a critical role in the progression of lung adenocarcinoma (LUAD). Recent studies have unveiled that targeting PLK1 improves the efficacy of immuno- therapy, highlighting its important role in the regulation of tumor immunity. Nevertheless, our understanding of the intricate interplay between PLK1 and the tumor microenvironment (TME) remains incomplete. Here, using genetically engineered mouse model and single- cell RNA-seq analysis, we report that PLK1 promotes an immunosuppressive TME in LUAD, characterized with enhanced M2 polarization of tumor associated macrophages (TAM) and dampened antigen presentation process. Mechanistically, elevated PLK1 coin- cides with increased secretion of CXCL2 …
