Reduced Light Availability Diminishes Mycorrhizal Growth Response Of Invasive Forb, Regina O'Kelley Dec 2017

Reduced Light Availability Diminishes Mycorrhizal Growth Response Of Invasive Forb, Regina O'Kelley

WWU Honors College Senior Projects

Arbuscular mycorrhizal fungi (AMF) form mycorrhizae, a common, well-studied symbiotic relationship. Controls on the magnitude and direction of plant mycorrhizal growth response (MGR) remain obscured. Specifically, the influence of light availability in the MGR of an invasive forb, spotted knapweed Centaurea stoebe, has not been studied. Greenhouse studies exploring the growth response of knapweed to arbuscular mycorrhizae (AM) often fail to report light intensity levels, which could impact the quality of their data. I conducted a greenhouse experiment studying the MGR in spotted knapweed under shaded and unshaded conditions, designed to approximate light availability in ambient greenhouse and full-sun …


Hodge Theory On Transversely Symplectic Foliations, Yi Lin Dec 2017

Hodge Theory On Transversely Symplectic Foliations, Yi Lin

Department of Mathematical Sciences Faculty Publications

In this paper, we develop symplectic Hodge theory on transversely symplectic foliations. In particular, we establish the symplectic dδ-lemma for any such foliations with the (transverse) s-Lefschetz property. As transversely symplectic foliations include many geometric structures, such as contact manifolds, co-symplectic manifolds, symplectic orbifolds, and symplectic quasi-folds as special examples, our work provides a unifying treatment of symplectic Hodge theory in these geometries.

As an application, we show that on compact K-contact manifolds, the s-Lefschetz property implies a general result on the vanishing of cup products, and that the cup length of a 2n+1 dimensional compact K-contact manifold with the …

Extracting Implicit Suggestions From Students’ Comments: A Text Analytics Approach, Venky Shankararaman, Swapna Gottipati, Jeff Rongsheng Lin, Sandy Gan

Research Collection School Of Computing and Information Systems

At the end of each course, students are required to give feedback on the course and instructor. This feedback includes quantitative rating using Likert scale and qualitative feedback as comments. Such qualitative feedback can provide valuable insights in helping the instructor enhance the course content and teaching delivery. However, the main challenge in analysing the qualitative feedback is the perceived increase in time and effort needed to manually process the textual comments. In this paper, we provide an automated solution for analysing comments, specifically extracting implicit suggestions from the students’ qualitative feedback comments. The implemented solution leverages existing text mining …

Examining The Relationships Between Gender Role Congruity, Identity, And The Choice To Persist For Women In Undergraduate Physics Majors, Bronwen Bares Pelaez

FIU Electronic Theses and Dissertations

Persistent gender disparity limits the available contributors to advancing some science, technology, engineering, and math (STEM) fields. While higher education can be an influential time-point for ensuring adequate participation, many physics programs across the U.S. have few women in classroom or lab settings. Prior research indicates that these women face considerable barriers. For university students, faculty, and administration to appropriately address these issues, it is important to understand the experiences of women as they navigate male-dominated STEM fields.

This explanatory sequential mixed methods study explored undergraduate female physics majors’ experiences with their male-dominated academic and research spaces in the U.S. …

Teaching Stats For Data Science, Daniel Kaplan Nov 2017

Teaching Stats For Data Science, Daniel Kaplan

Faculty Publications

“Data science” is a useful catchword for methods and concepts original to the field of statistics, but typically being applied to large, multivariate, observational records. Such datasets call for techniques not often part of an introduction to statistics: modeling, consideration of covariates, sophisticated visualization, and causal reasoning. This article re-imagines introductory statistics as an introduction to data science and proposes a sequence of 10 blocks that together compose a suitable course for extracting information from contemporary data. Recent extensions to the mosaic packages for R together with tools from the “tidyverse” provide a concise and readable notation for wrangling, visualization, …

Critical Digital Literacies Across Scales And Beneath The Screen, Noah Asher Golden Oct 2017

Critical Digital Literacies Across Scales And Beneath The Screen, Noah Asher Golden

Education Faculty Articles and Research

Digital technologies and education scholarship tend to focus on either individual creative design or analysis of the political economy. To better understand how ideologies travel across networks, critical digital literacies must focus on enactments beneath the screen, as the linguistic constructs known as software can enact interests across scales of activity to “disembed” local actions and meaning. Investigations of these mobilities and disembedding effects challenge popular notions of digital technologies as neutral, rendering overt the ways that algorithms can naturalize manifestations of power and social arrangements. Such a framework allows for descriptive analyses of the ways hegemonic discourses are enacted …
