Lopez, John A. Pojman, Fabio Del Piero, Daniel J. Hayes

Faculty Publications

© 2015 Mary Ann Liebert, Inc. A thiol-Acrylate-based copolymer synthesized via an amine-catalyzed Michael addition was studied in vitro and in vivo to assess its potential as an in situ polymerizing graft or augment in bone defect repair. The blends of hydroxyapatite (HA) with pentaerythritol triacrylate-co-trimethylolpropane (PETA), cast as solids or gas foamed as porous scaffolds, were evaluated in an effort to create a biodegradable osteogenic material for use as a bone-void-filling augment. Osteogenesis experiments were conducted with human adipose-derived mesenchymal stromal cells (hASCs) to determine the ability of the material to serve as an osteoinductive substrate. Poly(É-caprolactone) (PCL) composites …

Bond V. United States: Choosing The Lesser Of Two Evils, David L. Sloss

Faculty Publications

In Bond v. United States, Carol Anne Bond used toxic chemicals in an attempt to poison her husband’s lover. The federal government prosecuted Bond for violating the Chemical Weapons Convention Implementation Act of 1998 (the “CWC Act”). Congress enacted the CWC Act to implement U.S. obligations under the Chemical Weapons Convention (CWC), a multilateral treaty signed in 1993 that is designed to address the global threat posed by chemical weapons. Bond challenged the constitutional validity of the federal statute and urged the Court to overrule Missouri v Holland, a 1920 case holding that the combination of the Treaty Power and …

Special Speciation, Lyn L. Countryman, Jill D. Maroo

Faculty Publications

Considerable anecdotal evidence indicates that some of the most difficult concepts that both high school and undergraduate elementary-education students struggle with are those surrounding evolutionary principles, especially speciation. It’s no wonder that entry-level biology students are confused, when biologists have multiple definitions of “species.” We developed this speciation activity to provide clarity and allow students a hands-on experience with a speciation model.

Trends And Spatial Variability In Dry Spells Across The South-Central United States, Jill C. Trepanier, Michael J. Roberts, Barry D. Keim

Annual average and maximum spells with no precipitation in the southern United States are analyzed. In this study, dry spells are defined as consecutive days with no measurable rainfall. The study area includes 70 weather stations in Texas, Oklahoma, Louisiana, Arkansas, Mississippi, and Tennessee. Interarrival times between daily precipitation records for each station provide the data for this analysis. All 70 stations were analyzed from 1950 to 2013. Six stations that each have data for more than 100 years were analyzed for the period from 1908 to 2013. Approximately 25% of stations in the region show significant negative trends through …

Birds Of A Feather (Les Oiseaux De Même Plumage): Dynamic Soundscapes Using Real-Time Manipulation Of Locally Relevant Birdsongs, William Walker, Brian Belet

Faculty Publications

This paper and live audio demonstration explores the capabilities of using Web Audio API as a digital audio workstation (DAW) to manipulate sounds from massive server-side databases. Sonic source material comes from a database of birdsongs recorded worldwide by volunteer recordists at xeno-canto.org. Sounds from xeno-canto are chosen to match recent, nearby bird sightings submitted by volunteer birders at eBird. The result is a virtual soundscape derived from the sounds of birds currently present in the user’s geographical region. Our client-server architecture delegates database queries and archival storage to the server, leaving the client to concentrate on the aesthetic context …

The Ubiquitin Ligase Siah2 Regulates Obesity-Induced Adipose Tissue Inflammation, Gail Kilroy, Lauren E. Carter, Susan Newman, David H. Burk, Justin Manuel, Andreas Möller, David D. Bowtell, Randall L. Mynatt, Sujoy Ghosh, Z. Elizabeth Floyd

Faculty Publications

© 2015 The Obesity Society. Objective Chronic, low-grade adipose tissue inflammation associated with adipocyte hypertrophy is an important link in the relationship between obesity and insulin resistance. Although ubiquitin ligases regulate inflammatory processes, the role of these enzymes in metabolically driven adipose tissue inflammation is relatively unexplored. Herein, the effect of the ubiquitin ligase Siah2 on obesity-related adipose tissue inflammation was examined. Methods Wild-type and Siah2KO mice were fed a low- or high-fat diet for 16 weeks. Indirect calorimetry, body composition, and glucose and insulin tolerance were assayed along with glucose and insulin levels. Gene and protein expression, immunohistochemistry, adipocyte …

Reciprocal Osmotic Challenges Reveal Mechanisms Of Divergence In Phenotypic Plasticity In The Killifish Fundulus Heteroclitus, Reid S. Brennan, Fernando Galvez, Andrew Whitehead

Faculty Publications

© 2015. Published by The Company of Biologists Ltd. The killifish Fundulus heteroclitus is an estuarine species with broad physiological plasticity, enabling acclimation to diverse stressors. Previous work suggests that freshwater populations expanded their physiology to accommodate low salinity environments; however, it is unknown whether this compromises their tolerance to high salinity.We used a comparative approach to investigate the mechanisms of a derived freshwater phenotype and the fate of an ancestral euryhaline phenotype after invasion of a freshwater environment. We compared physiological and transcriptomic responses to high-and low-salinity stress in fresh and brackish water populations and found an enhanced plasticity …

Bioturbating Animals Control The Mobility Of Redox-Sensitive Trace Elements In Organic-Rich Mudstone, Dario Harazim, Duncan Mcilroy, Nicholas P. Edwards, Roy A. Wogelius, Phillip L. Manning, Kristin M. Poduska, Graham D. Layne, Dimosthenis Sokaras, Roberto Alonso-Mori, Uwe Bergmann

Faculty Publications

© 2015 Geological Society of America. Bioturbating animals modify the original mineralogy, porosity, organic content, and fabric of mud, thus affecting the burial diagenetic pathways of potential hydrocarbon source, seal, and reservoir rocks. High-sensitivity, synchrotron rapid scanning X-ray fluorescence elemental mapping reveals that producers of phycosiphoniform burrows systematically partition redox-sensitive trace elements (i.e., Fe, V, Cr, Mn, Co, Ni, Cu, and As) in fine-grained siliciclastic rocks. Systematic differences in organic carbon content (total organic carbon >1.5 wt%) and quality (Δ13Corg~0.6%) are measured between the burrow core and host sediment. The relative enrichment of redox-sensitive elements in the burrow core does …

The Use Of Shear Rate-Diameter Dose-Response Curves As An Alternative To The Flow-Mediated Dilation Test, Brian Wu, Daniel Credeur, Simon Fryer, Lee Stoner

Faculty Publications

The brachial artery flow-mediated dilation test (FMD) is the non-invasive gold-standard used to test endothelial function. Reduced FMD precedes the development of atherosclerosis and provides an early marker for predicting future cardiovascular disease events. Although, this test is of high potential, it is somewhat limited by poor reproducibility. By utilizing hand warming and grip exercise combined with hierarchical linear modeling, shear rate-diameter dose-response curves may provide a novel and more accurate way to assess endothelial function in humans. Shear rate-diameter dose-response curves could potentially improve upon the traditional FMD measurement and serve as a superior clinical and research tool for …

Estimating The Sex Composition Of The Summer Flounder Catch Using Fishery-Independent Data, Jason M. Morson, Eleanor A. Bochenek, Eric N. Powell, Emerson C. Hasbrouck, Jennifer E. Gius, Charles F. Cotton, Kristin Gerbino, Tara Froehlich

Faculty Publications

Models that account for sex-specific behavior and population dynamics are becoming more common in the stock assessment of sexually dimorphic fishes. However, such models can be data intensive and require some knowledge or assumptions about the sex ratio of fishery landings. A recent stock assessment review of Summer Flounder Paralichthys dentatus identified the need to account for sex-specific fishing mortality in the assessment model; however, no data on the sex composition of the catch were available. Fishery-independent, sex-specific information for this species is collected annually by the National Marine Fisheries Service's Northeast Fisheries Science Center during their bottom trawl survey. …

Learning Love From A Tiger: Approaches To Nature In An American Buddhist Monastery, Daniel S. Capper

Faculty Publications

In current debates about Buddhist approaches to the non-human natural world, studies describe Buddhism variously as anthropocentric, biocentric or ecocentric. These perspectives derive for the most part from examinations of philosophical and normative aspects of the tradition without much attention to moments when embodied practice diverges from religious ideals. Responding to the need for narrative thick descriptions of lived Buddhist attitudes toward nature, I ethnographically explore a Vietnamese monastery in the United States. There I find multifaceted Buddhist approaches to nature which sometimes disclose disunity between theory and practice. Philosophically and normatively, this monastery embraces ecocentrism through notions of interconnectedness, …

Faculty Publications

Poly(lactic-co-glycolic acid) or PLGA is a biodegradable polymer used in a wide range of medical applications. Specifically PLGA materials are also developed for the dental field in the form of scaffolds, films, membranes, microparticles, or nanoparticles. PLGA membranes have been studied with promising results, either alone or combined with other materials in bone healing procedures. PLGA scaffolds have been used to regenerate damaged tissues together with stem cell-based therapy. There is solid evidence that the development of PLGA microparticles and nanoparticles may be beneficial to a wide range of dental fields such as endodontic therapy, dental caries, dental surgery, dental …

Solving Russian Velars: Palatalization, The Lexicon And Gradient Contrast Utilization, Jeffery R. Parker

Faculty Publications

Палатализованные («мягкие») задненебные согласные в русском языке имеют особый статус, поскольку их появление можно предсказать лишь частично. Эти согласные являются примером часто встречающихся фонологических отношений, в которых звуки могут быть словоразличительными, но используются лишь в некоторых контекстах и/или словоформах. Такие «промежуточные фонологические отношения» (ОоШзткЬ 1995) представляют собой проблему для традиционных фонологических теорий, в которых звуки делятся на предсказуемые (аллофоны; содержатся в грамматике) и непредсказуемые (фонемы; содержатся в лексиконе). Таким образом, для научно-теоретической классификации вышеуказанных промежуточных фонологических отношений необходимо будет пересмотреть существующие предположения о природе и количестве информации, содержащейся в лексиконе. В данной статье я показываю, что и мягкие, и твердые …

Taking Back The Streets? How Street Art Ordinances Constitute Government Takings, Sheldon Evans

Faculty Publications

As street art continues to fuel a generation of counterculture and gains popularity in pop culture, laws enacted by local governments to curb this art form raise interesting constitutional issues surrounding the Fifth Amendment’s Takings Clause. More and more cities across America are classifying street art and graffiti as public nuisances. Such municipalities impose their agenda on private property owners with street art ordinances. These laws allow the government to come onto private property to remove the street art; some laws go even further by requiring the property owner to remove the street art at his own cost.

Fitting The Forum To The Pernicious Fuss: A Dispute System Design To Address Implicit Bias And 'Isms In The Workplace, Elayne E. Greenberg

Faculty Publications

(Excerpt)

This paper proposes a dispute system design to address workplace discrimination caused by implicit biases so that employees and employers involved in such disputes can secure a more responsive justice than existing legal processes are able to provide. Workplace discrimination caused by implicit bias continues to contaminate our work environment despite our focused legal efforts to combat such overt "isms" as sexism, racism, ageism, and ableism. Although overt expressions of bias have significantly decreased in recent years, expressions of implicit bias, the primary cause of workplace discrimination, persists.

This paper extends the research on implicit bias to dispute system …

Longstanding Agency Interpretations, Anita S. Krishnakumar

Faculty Publications

How much deference — or what kind — should courts give to longstanding agency interpretations of statutes? Surprisingly, courts and scholars lack a coherent answer to this question. Legal scholars long have assumed that longstanding agency statutory interpretations are treated with heightened deference on judicial review, and federal courts sometimes have made statements suggesting that this is the case. But in practice, federal court review of longstanding agency interpretations — at both the Court of Appeals and the U.S. Supreme Court levels — turns out to be surprisingly erratic. Reviewing courts sometimes note the longevity of an agency’s statutory interpretation …

Making Strategic Human Capital Relevant: A Time-Sensitive Opportunity, David Kryscynski, Dave Ulrich

Faculty Publications

The domain of strategic human capital is emerging at the intersection of strategy and strategic human resource management. Because it is still in the development phase, its core underlying assumptions have not yet solidified. This presents a unique and time-sensitive opportunity to explore and challenge these core assumptions and, specifically, to evaluate whether these assumptions mesh with the lived experiences of practicing managers. We argue that now is the time for the field to ground itself in practical phenomena so that its insights moving forward can be both academically rigorous and practically relevant. In this paper we illustrate the problems …

How Polymorphic Warnings Reduce Habituation In The Brain—Insights From An Fmri Study, Bonnie Brinton Anderson, C. Brock Kirwan, Jeffrey L. Jenkins, David Eargle, Seth Howard, Anthony Vance

Faculty Publications

Research on security warnings consistently points to habituation as a key reason why users ignore security warnings. However, because habituation as a mental state is difficult to observe, previous research has examined habituation indirectly by observing its influence on security behaviors. This study addresses this gap by using functional magnetic resonance imaging (fMRI) to open the “black box” of the brain to observe habituation as it develops in response to security warnings. Our results show a dramatic drop in the visual processing centers of the brain after only the second exposure to a warning, with further decreases with subsequent exposures. …

Lost (But Not Missing) At Work: Organizational Lostness As An Employee Response To Change, Lisa Jones Christensen, Scott C. Hammond

Faculty Publications

This article draws from the psychology of lost person behavior, established from wilderness search and rescue missions, to suggest that employees experience the condition of being lost within organizations. Data from wilderness searches, survivors, and organizational actors suggests that lessons from lost person behaviors apply in organizations. Reactions to being lost in an organization follow predictable patterns and include five specific stages: separation, isolation, deviation, deprivation, and realization. In defining the construct of organizational lostness and differentiating it from stress, coping, and resistance, we suggest an organizing framework to understand employee behaviors that would previously seem idiosyncratic. This article offers …

Causes And Consequences Of Ecosystem Service Regionalization In A Coastal Suburban Watershed, Wilfred M. Wollheim, M. B. Green, B. A. Pellerin, Nathaniel B. Morse, Charles S. Hopkinson

Faculty Publications

The demand for ecosystem services and the ability of natural ecosystems to provide those services evolve over time as population, land use, and management practices change. Regionalization of ecosystem service activity, or the expansion of the area providing ecosystem services to a population, is a common response in densely populated coastal regions, with important consequences for watershed water and nitrogen (N) fluxes to the coastal zone. We link biophysical and historical information to explore the causes and consequences of change in ecosystem service activity—focusing on water provisioning and N regulation—from 1850 to 2010 in a coastal suburban watershed, the Ipswich …
