English Scientific Writing: Avoiding Some Common Errors

Saturday, July 30 · 8:30 a.m. – 4:30 p.m.

Organizer:  Robert Trigiano, University of Tennessee, Knoxville, TN U.S.A.

Fee: $95

Competency in written language is necessary for anyone wishing to communicate on a global scale, whether writing for academia, journalism or business.  The number one reason why research/educational papers are rejected or why international employment is not offered to non-native English speakers is the lack of proficiency in written and oral English skills.  This intensive workshop was developed for United States and international audiences to improve their English writing (and presentation) skills.  Topics included in the workshop:  research and writing ethics (plagiarism), what makes a "good" writer, word misuse, topic sentences, titles, abstract, organization of papers, figures and tables, manuscript submission, and presentations. Preregistration is required.

Generalized Linear Mixed Models for Data Analysis in Plant Pathology

Saturday, July 30 · 10:00 a.m. – 5:00 p.m.

Organizers:  Larry Madden, The Ohio State University, Wooster, OH U.S.A.; Alissa Kriss, Syngenta, Greensboro, NC, U.S.A.

Sponsoring Committee/Sponsor:  Epidemiology Committee

Fee: $25

Registrants will learn to use the GLIMMIX procedure of SAS to analyze non-normal data for common problems in plant pathology. It is common to use mixed models instead of traditional ANOVA to analyze data from designed experiments and surveys. These models formally handle experiments with both fixed and random effects, and result in valid test statistics and standard errors for all the effects of interest under a wide range of circumstances. With mixed models, one can: directly and correctly analyze data from experiments with two or more sources of variation (e.g., split plots, multi-location studies); account for unequal variability (i.e., variances dependent on treatment); properly test for the effects of repeated measures (such as time during the growing season); and account for the correlation of spatially-referenced data. Linear mixed models (LMMs) have been most commonly used for analysis, which are strictly valid for continuous variables with a normal distribution. To fully handle data with a discrete distribution (such as disease incidence, lesion or spore counts) and other non-normal distributions, one must use generalized linear mixed models (GLMMs). There is compelling evidence that certain results can be biased or misleading when one uses LMMs for data that should be analyzed with GLMMs. Target of inference can be off with LMM (after transformation). Analysis using GLMMs is computationally demanding, and requires considerable care in defining the required model terms (for a given experimental and treatment design) and in interpreting output. Concepts of conditional and marginal models, of minor importance with LMMs, come to the forefront with GLMMs. 

All registrants must bring a laptop computer with version 9.3 or later of SAS installed. The free SAS University Edition is also acceptable. Previous attendees of mixed-model workshops can repeat this workshop. There will be a one hour lunch break, but lunch is not provided. Preregistration is required.

Identification of Phytophthora Species Using “The Online Identification Tools: Lucid Key, Tabular Key and Sequencing Analyses”

Saturday, July 30 · 8:30 a.m. – 12:00 p.m.

Organizers:  Z. Gloria Abad and John C. Bienapfl, USDA-APHIS-PPQ-S&T CPHST Beltsville Lab, Beltsville, MD U.S.A.

Sponsoring Committee/Sponsor:  Plant Pathogen and Disease Detection Committee; Diagnostics Committee

Fee: $70

The genus Phytophthora contains aggressive pathogens affecting important crops, forestry and natural ecosystems around the world. This workshop will help researchers understand the taxonomy and phylogeny of Phytophthora and correctly identify unknown isolates to species level based on morphological and molecular characterization, using BLAST and phylogenetic analysis, with specimens of the ex-holotypes or ex-neotypes.  After an overview of the contents of the resource, the participants will have the opportunity for hands-on use of the Online ID Tools developed by the instructors and international collaborators and advised by the USDA Identification Technology Program (ID Tools). This resource is the first of its kind for plant pathogens and is already posted online to be used free of charge. Participants should bring a computer to work on during the workshop demonstrations. Preregistration is required.

Introduction to Network Models in R

Saturday, July 30 · 1:00 – 4:00 p.m.

Organizers:  John Hernandez Nopsa, Ravin Poudel, and Karen Garrett, University of Florida, Gainesville, FL U.S.A.

Sponsoring Committee/Sponsor:  Epidemiology Committee

Fee: $30

Network models are becoming an important tool in many areas of plant pathology for understanding system complexity.  Participants will learn how to build and interpret network models and use the R programming environment to analyze network data in epidemiology, extension, genetics, and molecular biology.  Participants will come away with an understanding of how to apply network models to address a range of questions in plant pathology, with hands on experience. As part of this workshop, a short introduction to R will be provided. Participants must bring their own laptop with the latest R version. Preregistration is required. 

Make an Impact: How to Effectively Communicate your Scientific Message to the Public

Saturday, July 30 · 1:00 – 4:00 p.m.

Organizers:  Nicole Donofrio, University of Delaware, Newark, DE U.S.A., Juliet Marshall, University of Idaho, Idaho Falls, ID U.S.A.

Sponsoring Committee/Sponsor:  Office of Public Relations & Outreach (OPRO)

Fee: $25

This workshop will provide participants with tips and tools on how to effectively deliver scientific messages to the general public. Communication experts will share how to successfully combat scientific misinformation and convey the importance of your research and the benefits of science in a climate where funding for scientific research is at an all-time low. Whether you are tweeting about your lab’s research, explaining your science to high school students, pitching an idea to an NSF program leader, or lobbying on Capitol Hill, this workshop will help you become a more effective communicator.

The workshop will consist of two parts. First, Judith Humble, a Licensed Clinical Social Worker with 26 years of experience in teaching communication skills, will share techniques for overcoming resistance to change, managing negativity and establishing credibility. Then, Ruth Huhl Borger, Ed.D., APR, Assistant Vice President, and Tiffany Stephenson, Social Media Manager, both from IFAS/UF Communications, will guide you through hands-on activities, learning techniques and best practices for communicating your research in person and on social media.  Through fun, participatory exercises, attendees will “translate” basic info about their work to non-scientists and learn how to communicate through tweets and Facebook posts. Preregistration is required.

Using the R Statistical Computing Language for Reproducible Science

Saturday, July 30 · 8:30 – 11:30 a.m.

Organizers:  Niklaus Grunwald, USDA ARS, Corvallis, OR U.S.A.; Zhian Kamvar and Zach Foster, Oregon State University, Corvallis, ORU.S.A.

Sponsoring Committee/Sponsor:  Evolutionary Genetics and Genomics Committee; Epidemiology Committee

Fee: $40

This workshop introduces the use of the R statistical computing language for reproducible science. Reproducible science means providing data, code, images, and reports in such a way that experiments can be easily repeated or at least understood in detail. The R programming language has many free tools that can be used to integrate research data, methods, and explanation in sharable forms to facilitate reproducibility. Participants will learn how to use the RStudio Desktop application, Rmarkdown, and R functions to write reports, lab notebooks and actual finished manuscripts in pdf, word or html format. We will use examples from our work published in APS journals and housed on github in this hands-on workshop. Participants are expected to bring their own laptop (Linux, PC or Mac) with RStudio, R, and certain packages preinstalled. Preregistration is required.
