How Local Policymakers Respond to Information About Fines

Rebecca Goldstein, Michael Sances & Hye You
In this survey experiment, we present local public officials with one of two randomly chosen informational prompts about criminal justice fines and fees. We then follow up by asking how much new revenue the respondent would prefer from fines and fees versus taxes.

From Theory to Practice and Back Again: Lessons from Hostage Negotiation for Conflict Management

Deborah A Cai
This article is framed around principles drawn from hostage negotiation research and describes how those principles have been useful in managing professional conflicts. Research questions based on each set of experiences and principles are provide that could guide future research in conflict management.

Sequence conservation and structural features that are common within TRP channels

Deny Cabezas-Bratesco, Francisco A. McGee, Charlotte Colenso, Kattina Zavala, Danielle Granata, Vincenzo Carnevale, Juan Opazo & Sebastian Brauchi
TRP proteins are a large family of cation-selective channels, surpassed in variety only by voltage-gated potassium channels. Detailed molecular mechanisms governing how membrane voltage, ligand binding, or temperature can induce conformational changes promoting the open state in TRP channels are still a matter of debate. Aiming to unveil distinctive structural features common to the transmembrane domains within the TRP family, we performed phylogenetic reconstruction, sequence statistics, and structural analysis over a large set of TRP...

On the computational reproducibility of molecular phylogenies

Sudhir Kumar & Qiqing Tao
Reports on the lack of computational reproducibility of molecular phylogenies, produced in multiple runs of the same program or by different programs, cast a long shadow on downstream research using these phylogenies and on efforts to build the tree of life. We show that this irreproducibility does not decrease the accuracy of the reconstructed evolutionary relationships. Also, we find inferred molecular phylogenies to have log-likelihoods comparable to or better than the true phylogeny. Therefore, the...

Divergence time estimation using ddRAD data and an isolation-with-migration model applied to water vole populations of Arvicola

Jose Castresana, Alfonso Balmori-De La Puente, Jacint Ventura, Marcos Miñarro, Aitor Somoano & Jody Hey
Molecular dating methods of population splits are crucial in evolutionary biology, but they present important difficulties due to the complexity of the genealogical relationships of genes and past migrations between populations. Using the double digest restriction-site associated DNA (ddRAD) technique and an isolation-with-migration (IM) model, we studied the evolutionary history of water vole populations of the genus Arvicola, a group of complex evolution with fossorial and semi-aquatic ecotypes. To do this, we first estimated mutation...

Endemism, invasion, and overseas dispersal: The phylogeographic history of the Lesser Antillean frog, Eleutherodactylus johnstonei

Michael Yuan, Jeffrey Frederick, Jimmy McGuire, Rayna Bell, Struan Smith, Calvin Fenton, Jourdan Cassius, Rudell Williams, Ian Wang, Robert Powell & S. Blair Hedges
Cryptogenic species, those whose native and introduced ranges are unknown, pose a challenge not only to conservation but also to studies of ecology, biogeography, and evolution. One such species is the Lesser Antillean frog, Eleutherodactylus johnstonei, which is broadly distributed through the Caribbean and mainland South America. The Lesser Antilles pose a particular challenge with regard to cryptogenic species because these islands have been anthropogenically connected since before recorded history. We combined genetic (available on...

Spatial Perceptions

Lindsay Ouellette, Donald Hantula & Drew Kronstadt
This study will be measuring proxemic distance and comfort levels by using videos to show hypothetical situations of the subject being approached or approaching another human or robot. The subject will then have to pause the video at the moment they imagine themselves that the human or robot was too close or in their personal space. We measure at what distances comfort levels change. We will also be measuring anxiety levels toward robots using the...

Localized carry-over effects of pond drying on survival, growth, and pathogen defenses in amphibians

Emily Le Sage
Climate change is increasing variability in precipitation patterns in many parts of the globe. Unpredictable changes in water availability can be particularly challenging for organisms that rely on precipitation-fed water sources for completing their life cycle, such as many amphibian species. Although developmental plasticity can mitigate the impacts of changing environments for some species, this strategy can come at a cost to other fitness-linked traits, such as immune function. We investigated localized variation in the...

How early does the selfing syndrome arise? Associations between selfing ability and flower size within populations of the mixed mater Collinsia verna

Robert M McElderry, Rachel B Spigler, Donna W Vogler & Susan Kalisz
Widespread associations between selfing rate and floral size within and among taxa suggest that these traits may evolve in concert. Does this association develop immediately, because of shared genetic/developmental control, or stepwise with selection shaping the evolution of one trait following the other? If the former, then association ought to appear within and across populations. We explore this fundamental question in three populations of the mixed-mater Collinsia verna where autonomous selfing (AS) ability has been...

Relationship of semantic distance to spoken production in aphasia and healthy older adults

Celia Litovsky, Ann Finley, Bonnie Zuckerman, Matthew Sayers, Yoed Kenett & Jamie Reilly
This is a retrospective study using utterances in the TalkBank and AphasiaBank databases. The general research questions addressed in this study are: (1) Does the extent of aphasic participants' semantic impairment relate to their overall aphasia severity? (2) Does the word-to-word taxonomic and thematic semantic distance during picture description and narrative tasks differ between healthy controls and aphasic individuals? (3) Does the relationship between word-to-word taxonomic and thematic semantic distance differ for healthy controls and...

Transforming Institutions: Accelerating Systemic Change in Higher Education

Kate White, Andrea Beach, Noah Finkelstein, Charles Henderson, Scott Simkins, Linda Slakey, Marilyne Stains, Gabriela Weaver & Lorne Whitehead
This volume of Transforming Institutions follows from and builds on its predecessor of five years ago (Weaver et al., 2015) with a mix of case studies, models, and analyses. The authors and editors provide key perspectives for advancing change initiatives in higher education and STEM education. The Transforming Institutions conferences and book series began with the first convening in 2011 at Purdue University, organized by the Discovery Learning Research Center (DLRC), and continues with the...

Paninvasion severity assessment of a U.S. grape pest to disrupt the global wine market

Nicholas Huron, Jocelyn Behm & Matthew Helmus
Economic impacts from plant pests are often felt at the regional scale, yet some impacts expand to the global scale through the alignment of a pest’s invasion potentials. Such globally invasive species (i.e., paninvasives) are like the human pathogens that cause pandemics. Like pandemics, assessing paninvasion risk for an emerging regional pest is key for stakeholders to take early actions that avoid market disruption. Here, we develop the paninvasion severity assessment framework and use it...
