Frequency Of Invasive Plant Occurrence Is Not A Suitable Proxy For Abundance In The Northeast United States, Tyler Cross, John T. Finn, Bethany A. Bradley
Frequency Of Invasive Plant Occurrence Is Not A Suitable Proxy For Abundance In The Northeast United States, Tyler Cross, John T. Finn, Bethany A. Bradley
Environmental Conservation Faculty Publication Series
Measuring and predicting invasive plant abundance is critical for understanding impacts on ecosystems and economies. Although spatial abundance datasets remain rare, occurrence datasets are increasingly available across broad regional scales. We asked whether the frequency of these point occurrences can be used as a proxy for abundance of invasive plants. We compiled both occurrence and abundance data for 13 regionally important invasive plants in the northeast United States from herbarium records and several contributed distribution datasets. We integrated all available abundance information based on infested area, stem count, percent cover, or qualitative descriptions into abundance rankings ranging from 0 (absent) …
Cheatgrass (Bromus Tectorum) Distribution In The Intermountain Western United States And Its Relationship To Fire Frequency, Seasonality, And Ignitions, Bethany A. Bradley, Caroline A. Curtis, Emily J. Fusco, John T. Abatzoglou, Jennifer K. Balch, Sepideh Dadashi, Mao-Ning Tuanmu
Cheatgrass (Bromus Tectorum) Distribution In The Intermountain Western United States And Its Relationship To Fire Frequency, Seasonality, And Ignitions, Bethany A. Bradley, Caroline A. Curtis, Emily J. Fusco, John T. Abatzoglou, Jennifer K. Balch, Sepideh Dadashi, Mao-Ning Tuanmu
Environmental Conservation Faculty Publication Series
Cheatgrass (Bromus tectorum) is an invasive grass pervasive across the Intermountain Western US and linked to major increases in fire frequency. Despite widespread ecological impacts associated with cheatgrass, we lack a spatially extensive model of cheatgrass invasion in the Intermountain West. Here, we leverage satellite phenology predictors and thousands of field surveys of cheatgrass abundance to create regional models of cheatgrass distribution and percent cover. We compare cheatgrass presence to fire probability, fire seasonality and ignition source. Regional models of percent cover had low predictive power (34% of variance explained), but distribution models based on a threshold of …
Cultivating Conceptions Of Masculinity: Television And Perceptions Of Masculine Gender Role Norms, Erica Scharrer, Greg Blackburn
Cultivating Conceptions Of Masculinity: Television And Perceptions Of Masculine Gender Role Norms, Erica Scharrer, Greg Blackburn
Communication Department Faculty Publication Series
The potential of television to both reflect and shape cultural understandings of gender roles has long been the subject of social scientific inquiry. The present study employed survey methodology with 420 emerging adult respondents (aged 18 to 25) in a national U.S. sample to explore associations between amount of time spent viewing television and views about “ideal” masculine gender roles. The viewing of particular television genres was explored in addition to (and controlling for) overall amount of time spent with the medium, using cultivation theory as the theoretical foundation. Results showed significant statistical associations between viewing sitcoms, police and detective …
Practices Of Topic And Dialogue Activity Management In Dispute Mediation, Alena L. Vasilyeva
Practices Of Topic And Dialogue Activity Management In Dispute Mediation, Alena L. Vasilyeva
Communication Department Faculty Publication Series
This study examines the mediator practices to bring the interaction back on track when the participants of dispute mediation go off-task. An existing collection of 18 transcripts from audio recordings of mediation sessions at a mediation center in the western United States serves as a source of interactional data. First, the study examines the moves mediators make to perform interventions to bring the current state of activity more in line with mediation activity. Second, it accounts for the variety of interventions mediators perform using the concepts of face and facework. The article discusses what the findings mean in terms of …
Queer Cosmopolitanism In The Disaster Zone: "My Grindr Became The United Nations", Jonathan Corpus Ong
Queer Cosmopolitanism In The Disaster Zone: "My Grindr Became The United Nations", Jonathan Corpus Ong
Communication Department Faculty Publication Series
This article reflects on the significance of cosmopolitan socialities and intimacies following disasters, and the opportunities and risks they offer for restorative and reparative action for survivors and their communities. Reporting in particular on the experiences of LGBTQ Filipinos in post-Haiyan Tacloban, I discuss how the presence of foreign aid workers in everyday social spaces provided opportunities for queer identity expression and social attachments. I argue that cosmopolitan socialities, including new connections initiated via mobile dating platforms, were embraced by LGBTQs for their potential to share and repurpose wounds after rupture, especially in a conservative small-town context where LGBTQ identities …
Strategic Maneuvering In Dispute Mediation, Alena L. Vasilyeva
Strategic Maneuvering In Dispute Mediation, Alena L. Vasilyeva
Communication Department Faculty Publication Series
The study examines transcripts from dispute mediation to explore mediators’ strategic maneuvering for keeping the disputants on task – that is, on negotiating plans about caring for their children. The article discusses mediators’ institutional practices to keep disputants on task and to constrain what becomes arguable. It analyzes strategic maneuvering at the levels of topical potential, audience demands, and presentational devices. The study also suggests that the concept of strategic maneuvering can be further developed by including identities as another type of interactional resources employed to shape argumentative activity. It focuses on how mediators use interactional resources to balance institutional …
The Real Housewives, Gendered Affluence, And The Rise Of The Docusoap, Alison Brzencheck, Mari Castañeda
The Real Housewives, Gendered Affluence, And The Rise Of The Docusoap, Alison Brzencheck, Mari Castañeda
Communication Department Faculty Publication Series
In this paper we position gendered affluence as a representational trend in dramatic comedies (e.g., Sex and the City [SATC]) and docusoaps (e.g., The Real Housewives [TRH]) that coalesces around themes like hyper-femininity, nouveau riche values, and conspicuous lifestyle. Through our analysis we suggest that institutional practices (identity politics, cybernetic commodification, and post-feminist technological interactivity) situated in a neoliberal context and a remediated environment enable the systematic reproduction of gendered affluence in the broader landscape of women’s television. The process of remediation is used as a lens to examine how the docusoap differs from (the immediacy …

"Only In This Way Is Social Progress Possible": Early Cinema, Gender, And The Social Survey Movement, Shawn Shimpach
"Only In This Way Is Social Progress Possible": Early Cinema, Gender, And The Social Survey Movement, Shawn Shimpach
Communication Department Faculty Publication Series
Seeing people as audiences has a history. Our current ways of seeing people are especially indebted to the conjuncture of Progressive Era reform efforts, the early development of the social sciences, and the transformation of the cinema into a mass medium in the first decades of the twentieth century in the United States. One important convergence of all these historical developments was the Social Survey Movement, which, through its efforts to measure the need for reform, popularized the construction of the modern media audience out of atomized, measurable categorizations of people. The cause of reform at this time was often …
Creative Resonance And Misalignment Stance: Achieving Distance In One Hebrew Interaction, Gonen Dori-Hacohen
Creative Resonance And Misalignment Stance: Achieving Distance In One Hebrew Interaction, Gonen Dori-Hacohen
Communication Department Faculty Publication Series
This paper elaborates on one element of the theory of Dialogic Syntax, Du Bois’ main tool for stance-taking, namely creative resonance. The examples are taken from a recording of a car ride which was part of data collected for the analysis of Hebrew. The focus in the analysis is on misalignment, when participants use stance acts to distance themselves from each other. The main claim of this paper is that whenever a stance act takes place, the relations between the participants are at stake. I show how creative, and to a lesser extent pre-existing, resonance can be used for creating …

Explaining White Opposition To Black Political Leadership: The Role Of Fear Of Racial Favoritism, Seth K. Goldman
Explaining White Opposition To Black Political Leadership: The Role Of Fear Of Racial Favoritism, Seth K. Goldman
Communication Department Faculty Publication Series
Despite the election of America's first Black president, most non‐Hispanic Whites continue to oppose Black political leadership. The conventional explanation for White opposition is sheer racial prejudice, yet the available empirical evidence for this theory is inconsistent. I test an alternative theory that Whites perceive Black political leaders as a threat to their group's interests. Using a new survey measure and nationally representative panel data covering the 2008, 2010, and 2012 U.S. elections, I find that a majority of Whites perceive Black elected officials as likely to favor Blacks over Whites. Moreover, fear of racial favoritism predicts support for Barack …

A Unified Marxist Approach To Accumulation And Crisis In Capitalist Economies, Deepankar Basu
A Unified Marxist Approach To Accumulation And Crisis In Capitalist Economies, Deepankar Basu
Economics Department Working Paper Series
An economic crisis in capitalism is a deep and prolonged interruption of the economy-wide circuit of capital. Crises emerge from within the logic of capitalism’s operation, and are manifestations of the inherently contradictory process of capital accumulation. The Marxist tradition conceptualizes two types of crisis tendencies in capitalism: a crisis of deficient surplus value and a crisis of excess surplus value. Two mechanisms that become important in crises of deficient surplus value are the rising organic composition of capital and the profit squeeze; two mechanisms that are salient in crisis of excess surplus value are problems of insufficient aggregate demand …

Sport In An Authoritarian Regime: The Primo De Rivera Era In Spain, 1923-30, Brian D. Bunk
History Department Faculty Publication Series
The 1920s were part of Spanish literature’s Silver Age but for some of the nation’s athletes it was more of a Golden Age. The national football team won the silver medal at the 1920 Olympic games and in 1929 became the first team outside the United Kingdom to beat England. In 1926, heavyweight boxer Paulino Uzcudun claimed the European championship and tennis star Lili Alvarez began a run of three consecutive women’s singles finals at Wimbledon. Many of these sporting successes came during the dictatorship of General Miguel Primo de Rivera who seized power in 1923. Analyzing the dictatorship’s attitudes …

On Improving Reliability Of Sram-Based Physically Unclonable Functions, Arunkumar Vijayakumar, Vinay C. Patil, Sandip Kundu
Electrical and Computer Engineering Faculty Publication Series
Physically unclonable functions (PUFs) have been touted for their inherent resistance to invasive attacks and low cost in providing a hardware root of trust for various security applications. SRAM PUFs in particular are popular in industry for key/ID generation. Due to intrinsic process variations, SRAM cells, ideally, tend to have the same start-up behavior. SRAM PUFs exploit this start-up behavior. Unfortunately, not all SRAM cells exhibit reliable start-up behavior due to noise susceptibility. Hence, design enhancements are needed for improving reliability. Some of the proposed enhancements in literature include fuzzy extraction, error-correcting codes and voting mechanisms. All enhancements involve a …

Does Order Matter? Investigating The Effect Of Sequence On Glance Duration During On-Road Driving, Joonbum Lee, Shannon C. Roberts, Bryan Reimber, Bruce Mehler
Mechanical and Industrial Engineering Faculty Publication Series
Previous literature has shown that vehicle crash risks increases as drivers’ off-road glance duration increases. Many factors influence drivers’ glance duration such as individual differences, driving environment, or task characteristics. Theories and past studies suggest that glance duration increases as the task progresses, but the exact relationship between glance sequence and glance durations is not fully understood. The purpose of this study was to examine the effect of glance sequence on glance duration among drivers completing a visual-manual radio tuning task and an auditory-vocal based multi-modal navigation entry task. Eighty participants drove a vehicle on urban highways while completing radio …

Microfluidics: From Crystallization To Serial Time-Resolved Crystallography, Shuo Sui, Sarah L. Perry
Microfluidics: From Crystallization To Serial Time-Resolved Crystallography, Shuo Sui, Sarah L. Perry
Chemical Engineering Faculty Publication Series
Capturing protein structural dynamics in real-time has tremendous potential in elucidating biological functions and providing information for structure-based drug design. While time-resolved structure determination has long been considered inaccessible for a vast majority of protein targets, serial methods for crystallography have remarkable potential in facilitating such analyses. Here, we review the impact of microfluidic technologies on protein crystal growth and X-ray diffraction analysis. In particular, we focus on applications of microfluidics for use in serial crystallography experiments for the time-resolved determination of protein structural dynamics.

Sequence And Entropy-Based Control Of Complex Coacervates, Li-Wei Chang, Tyler K. Lytle, Mithun Radhakrishna, Joel J. Madinya, Jon Vélez, Charles E. Sing, Sarah L. Perry
Chemical Engineering Faculty Publication Series
Biomacromolecules rely on the precise placement of monomers to encode information for structure, function, and physiology. Efforts to emulate this complexity via the synthetic control of chemical sequence in polymers are finding success; however, there is little understanding of how to translate monomer sequence to physical material properties. Here we establish design rules for implementing this sequence-control in materials known as complex coacervates. These materials are formed by the associative phase separation of oppositely charged polyelectrolytes into polyelectrolyte dense (coacervate) and polyelectrolyte dilute (supernatant) phases. We demonstrate that patterns of charges can profoundly affect the charge–charge associations that drive this …
Strain-Stiffening Gels Based On Latent Crosslinking, Yen H. Tran, Matthew J. Rasmuson, Todd Emrick, John Klier, Shelly Peyton
Strain-Stiffening Gels Based On Latent Crosslinking, Yen H. Tran, Matthew J. Rasmuson, Todd Emrick, John Klier, Shelly Peyton
Chemical Engineering Faculty Publication Series
Gels are an increasingly important class of soft materials with applications ranging from regenerative medicine to commodity materials. A major drawback of gels is their relative mechanical weakness, which worsens further under strain. We report a new class of responsive gels with latent crosslinking moieties that exhibit strain-stiffening behavior. This property results from the lability of disulfides, initially isolated in a protected state, then activated to crosslink on-demand. The active thiol groups are induced to form inter-chain crosslinks when subjected to mechanical compression, resulting in a gel that strengthens under strain. Molecular shielding design elements regulate the strain-sensitivity and spontaneous …

Improved in vitro models are needed to better understand cancer progression and bridge the gap between in vitro proof-of-concept studies, in vivo validation, and clinical application. Multicellular tumor spheroids (MCTS) are a popular method for three-dimensional (3D) cell culture, because they capture some aspects of the dimensionality, cell–cell contact, and cell–matrix interactions seen in vivo. Many approaches exist to create MCTS from cell lines, and they have been used to study tumor cell invasion, growth, and how cells respond to drugs in physiologically relevant 3D microenvironments. However, there are several discrepancies in the observations made of cell behaviors when comparing …

Global warming has increased the frequency of extreme climate events, yet responses of biological and human communities are poorly understood, particularly for aquatic ecosystems and fisheries. Retrospective analysis of known outcomes may provide insights into the nature of adaptations and trajectory of subsequent conditions. We consider the 1815 eruption of the Indonesian volcano Tambora and its impact on Gulf of Maine (GoM) coastal and riparian fisheries in 1816. Applying complex adaptive systems theory with historical methods, we analyzed fish export data and contemporary climate records to disclose human and piscine responses to Tambora’s extreme weather at different spatial and temporal …

Ecosystem Service Supply And Capacity On U.S. Family Forestlands, Jesse Caputo, Brett Butler
Environmental Conservation Faculty Publication Series
Individuals and families collectively own more than 118 million ha of forestland in the USA. Using data from the USDA Forest Service’s National Woodland Owners Survey (NWOS), we characterize ecosystem services being produced on family forests as well as the beneficiaries who enjoy them. Approximately half of family forest owners provide one or more provisioning services. With the exception of logs, the provisioning services provided by the majority of owners are enjoyed directly by owners or their close associates (i.e., family, friends, and neighbors). Similarly, while more than half of family forest owners have provided recreational opportunities, a cultural service, …
