Colorado's Agrability Project's Effects On Kasa And Practice Changes With Agricultural Producers And Professionals Dec 2015

Colorado's Agrability Project's Effects On Kasa And Practice Changes With Agricultural Producers And Professionals

Journal of Extension

Disability rates resulting from work-related injuries remain steadily high among farmers and ranchers. To address the gap in services within this population, USDA implemented AgrAbility nationally. Using part of Bennett's hierarchical model, the current study evaluated the KASA and practice change levels of 401 farmers and ranchers and compared them to the levels of 401 AgrAbility professionals who participated in Colorado AgrAbility Project workshops (1998-2013). Results indicated that although KASA and practice change levels decreased somewhat from immediately following the workshop to follow-up, 90%-98% of participants reported KASA improvements 4 months afterwards. Implications are discussed.

Application Of Implan To Extension Programs: Economic Impacts Of The University Of Arizona Cooperative Extension Snap-Ed Spending, Ashley Kerna, George Frisvold, Laurel Jacobs, Vanessa A. Farrell, Linda Houtkooper, Scottie Misner Dec 2015

Application Of Implan To Extension Programs: Economic Impacts Of The University Of Arizona Cooperative Extension Snap-Ed Spending, Ashley Kerna, George Frisvold, Laurel Jacobs, Vanessa A. Farrell, Linda Houtkooper, Scottie Misner

Journal of Extension

Many Extension programs are turning to the input-output software IMPLAN to demonstrate economic impacts. IMPLAN is a powerful tool that can be used to estimate the total economic activity associated with an industry, event, or policy. One possible application, therefore, is to use program spending data to estimate the economic effects of Extension's presence in the region. Yet results should be interpreted with care because they can report gross‑rather than net—economic effects. This article provides an example of IMPLAN application by estimating the net change in state economic activity resulting from University of Arizona Cooperative Extension SNAP-Ed spending.

Mechanical and Materials Engineering Faculty Publications and Presentations

Global poverty reduction efforts value monitoring and evaluation, but often struggle to translate lessons learned from one intervention into practical application in another intervention. Commonly, data is not easily or often shared between interventions and summary data collected as part of an impact evaluation is often not available until after the intervention is complete. Equally limiting, the workflows that lead to research results are rarely published in a reproducible, reusable, and easy-to-understand fashion for others. Information and communication technologies widely used in commercial and government pro- grams are growing in relevance for international global development professionals and offer a potential …

Predicted Stresses In A Ball-Grid-Array (Bga)/Column-Grid-Array (Cga) Assembly With A Low Modulus Solder At Its Ends, Ephraim Suhir, Reza Ghaffarian

Mechanical and Materials Engineering Faculty Publications and Presentations

A simple, easy-to-use and physically meaningful predictive model is suggested for the assessment of thermal stresses in a ball-grid-array or a column-grid-array with a low modulus solder material at the peripheral portions of the assembly. It is shown that the application of such a design can lead to a considerable relief in the interfacial stresses, even to an extent that inelastic strains in the solder joints could be avoided. If this happens, the fatigue strength of the bond and of the assembly as a whole will be improved dramatically: low-cycle fatigue conditions will be replaced by the elastic fatigue condition, …

A Benchmark And Comparative Study Of Video-Based Face Recognition On Cox Face Database, Zhiwu Huang, S. Shan, R. Wang, H. Zhang, S. Lao, A. Kuerban, X. Chen

Research Collection School Of Computing and Information Systems

Face recognition with still face images has been widely studied, while the research on video-based face recognition is inadequate relatively, especially in terms of benchmark datasets and comparisons. Real-world video-based face recognition applications require techniques for three distinct scenarios: 1) Videoto-Still (V2S); 2) Still-to-Video (S2V); and 3) Video-to-Video (V2V), respectively, taking video or still image as query or target. To the best of our knowledge, few datasets and evaluation protocols have benchmarked for all the three scenarios. In order to facilitate the study of this specific topic, this paper contributes a benchmarking and comparative study based on a newly collected …

A Misspecification Test For Logit Based Route Choice Models, Tien Mai, Emma Frejinger, Fabian Bastin

Research Collection School Of Computing and Information Systems

The multinomial logit (MNL) model is often used for analyzing route choices in real networks in spite of the fact that path utilities are believed to be correlated. Yet, statistical tests for model misspecification are rarely used. This paper shows how the information matrix test for model misspecification proposed byWhite (1982) can be applied to test path-based and link-based MNL route choice models.We present a Monte Carlo experiment using simulated data to assess the size and the power of the test and to compare its performance with the IIA (Hausman and McFadden, 1984) and McFadden–Train Lagrange multiplier (McFadden and Train, …

Discrete Davydov's Soliton In Α-Helical Protein Molecule With Anharmonic Hydrogen Bond And Thermal Noise, Frank T. Ndjomatchoua, Clément Tchawoua, Joël D.T. Tchinang, Bruno P. Lerü, Henri E.Z. Tonnang

All Peer-Reviewed Publications

An improvement of the Davydov's model for energy transfer in α-helix protein is proposed. Using hyperbolic cosine potential type to model hydrogen bond potential, we have obtained from the adiabatic approximation, a discrete nonlinear Schrödinger equation with inverse hyperbolic sine nonlinearity. Using the two-dimensional discrete map approach, we have found a linearly stable intrinsic localized mode of the corresponding developed equation. Mobility of the intrinsic localized mode was achieved by moving the local impurity hypothesized as the anomalous band energy. The reactivity of the discrete breather under thermal noise was studied numerically with the Langevin's approach. It was shown that …

Research Collection Yong Pung How School Of Law

In a commentary, SMU Associate Professor of Law Eugene Tan pointed out that it is absolutely essential to the fight against terrorism that the operational imperative of order and security be balanced against the critical need to ensure that the values a society holds dear are not compromised or undermined. It would be unfair and profoundly subversive to its social cohesion for France to expect the majority of its Muslims to take responsibility for the acts of a few. He added that what is at stake is the inclusiveness of the French national identity, heritage and values — its figurative …

Content-Based Visual Landmark Search Via Multimodal Hypergraph Learning, Lei Zhu, Jialie Shen, Hai Jin, Ran Zheng, Liang Xie Dec 2015

Content-Based Visual Landmark Search Via Multimodal Hypergraph Learning, Lei Zhu, Jialie Shen, Hai Jin, Ran Zheng, Liang Xie

Research Collection School Of Computing and Information Systems

While content-based landmark image search has recently received a lot of attention and became a very active domain, it still remains a challenging problem. Among the various reasons, high diverse visual content is the most significant one. It is common that for the same landmark, images with a wide range of visual appearances can be found from different sources and different landmarks may share very similar sets of images. As a consequence, it is very hard to accurately estimate the similarities between the landmarks purely based on single type of visual feature. Moreover, the relationships between landmark images can be …

Robust Execution Strategies For Project Scheduling With Unreliable Resources And Stochastic Durations, Na Fu, Hoong Chuin Lau, Pradeep Varakantham Dec 2015

Robust Execution Strategies For Project Scheduling With Unreliable Resources And Stochastic Durations, Na Fu, Hoong Chuin Lau, Pradeep Varakantham

Research Collection School Of Computing and Information Systems

The resource-constrained project scheduling problem with minimum and maximum time lags (RCPSP/max) is a general model for resource scheduling in many real-world problems (such as manufacturing and construction engineering). We consider RCPSP/max problems where the durations of activities are stochastic and resources can have unforeseen breakdowns. Given a level of allowable risk, (Formula presented.), our mechanisms aim to compute the minimum robust makespan execution strategy. Robust makespan for an execution strategy is any makespan value that has a risk less than (Formula presented.). The risk for a makespan value, (Formula presented.) given an execution strategy, is the probability that a …

On The Unreliability Of Bug Severity Data, Yuan Tian, Nasir Ali, David Lo, Ahmed E. Hassan Dec 2015

On The Unreliability Of Bug Severity Data, Yuan Tian, Nasir Ali, David Lo, Ahmed E. Hassan

Research Collection School Of Computing and Information Systems

Severity levels, e.g., critical and minor, of bugs are often used to prioritize development efforts. Prior research efforts have proposed approaches to automatically assign the severity label to a bug report. All prior efforts verify the accuracy of their approaches using human-assigned bug reports data that is stored in software repositories. However, all prior efforts assume that such human-assigned data is reliable. Hence a perfect automated approach should be able to assign the same severity label as in the repository – achieving a 100% accuracy. Looking at duplicate bug reports (i.e., reports referring to the same problem) from three open-source …

A Cooperative Coevolution Framework For Parallel Learning To Rank, Shuaiqiang Wang, Yun Wu, Byron J. Gao, Ke Wang, Hady W. Lauw, Jun Ma Dec 2015

A Cooperative Coevolution Framework For Parallel Learning To Rank, Shuaiqiang Wang, Yun Wu, Byron J. Gao, Ke Wang, Hady W. Lauw, Jun Ma

Research Collection School Of Computing and Information Systems

We propose CCRank, the first parallel framework for learning to rank based on evolutionary algorithms (EA), aiming to significantly improve learning efficiency while maintaining accuracy. CCRank is based on cooperative coevolution (CC), a divide-and-conquer framework that has demonstrated high promise in function optimization for problems with large search space and complex structures. Moreover, CC naturally allows parallelization of sub-solutions to the decomposed sub-problems, which can substantially boost learning efficiency. With CCRank, we investigate parallel CC in the context of learning to rank. We implement CCRank with three EA-based learning to rank algorithms for demonstration. Extensive experiments on benchmark datasets in …

Modeling Social Media Content With Word Vectors For Recommendation, Ying Ding, Jing Jiang Dec 2015

Modeling Social Media Content With Word Vectors For Recommendation, Ying Ding, Jing Jiang

Research Collection School Of Computing and Information Systems

In social media, recommender systems are becoming more and more important. Different techniques have been designed for recommendations under various scenarios, but many of them do not use user-generated content, which potentially reflects users’ opinions and interests. Although a few studies have tried to combine user-generated content with rating or adoption data, they mostly reply on lexical similarity to calculate textual similarity. However, in social media, a diverse range of words is used. This renders the traditional ways of calculating textual similarity ineffective. In this work, we apply vector representation of words to measure the semantic similarity between text. We …

Classical Pentecostal Interpretation Of The Gift Of Discernment From 1914 To 1941, Stephanie Ann Rose Dec 2015

Classical Pentecostal Interpretation Of The Gift Of Discernment From 1914 To 1941, Stephanie Ann Rose

Electronic Theses and Dissertations

From the beginning of the Pentecostal Movement in 1906, Pentecostal meetings were plagued by what they labeled “counterfeit manifestations.” These manifestations were creating negative consequences for the movement and Pentecostals needed a strategy that would identify and eradicate them from their meetings. Because Pentecostalism was in its infancy, it did not have a clear procedure to assist in identifying counterfeit manifestations, to determine how they operated, and/or who or what produced them. Over time they began to form assumptions regarding the operation of counterfeit manifestations and developed several strategies that they hoped would counteract their presence in meetings, one of …
