Psychology Faculty Research and Publications

Background

This study sought to investigate the effectiveness of group treatment for trichotillomania (TTM) in ordinary clinical settings. Treatment consisted of a combination of habit reversal training (HRT) and acceptance and commitment treatment (ACT). Both short- and long-term effects were explored, as well as individual change trajectories.

Methods

The sample consist of fifty-three patients with TTM. Treatment outcomes were evaluated at post-treatment and at one-year follow-up using self-report questionnaires (Massachusetts General Hospital Hair Pulling Scale, MGH-HS), structured clinical interviews (National Institute of Mental Health Trichotillomania Severity Scale, NIMH-TSS), and the Clinical Global Impression scale for TTM (CGI-TTM).

Tick Haller's Organ, A New Paradigm For Arthropod Olfaction: How Ticks Differ From Insects, Ann L. Carr, Robert D. Michell Iii, Anirudh Dhammi, Brooke W. Bissinger, Daniel E. Sonenshine, R. Michael Roe

Biological Sciences Faculty Publications

Ticks are the vector of many human and animal diseases; and host detection is critical to this process. Ticks have a unique sensory structure located exclusively on the 1st pairs of legs; the fore-tarsal Haller's organ, not found in any other animals, presumed to function like the insect antennae in chemosensation but morphologically very different. The mechanism of tick chemoreception is unknown. Utilizing next-generation sequencing and comparative transcriptomics between the 1st and 4th legs (the latter without the Haller's organ), we characterized 1st leg specific and putative Haller's organ specific transcripts from adult American dog ticks, Dermacentor variabilis. The …

Fit To Predict? Ecoinformatics For Predicting The Catchability Of A Pelagic Fish In Near Real-Time, Kylie L. Scales, Elliot L. Hazen, Sara M. Maxwell, Heidi Dewar, Suzanne Kohin, Michael G. Jacox, Christopher A. Edwards, Dana K. Briscoe, Larry B. Crowder, Rebecca L. Lewison, Steven J. Bograd

Biological Sciences Faculty Publications

The ocean is a dynamic environment inhabited by a diverse array of highly migratory species, many of which are under direct exploitation in targeted fisheries. The timescales of variability in the marine realm coupled with the extreme mobility of ocean-wandering species such as tuna and billfish complicates fisheries management. Developing ecoinformatics solutions that allow for near real-time prediction of the distributions of highly mobile marine species is an important step towards the maturation of dynamic ocean management and ecological forecasting. Using 25 years (1990-2014) of NOAA fisheries' observer data from the California drift gillnet fishery, we model relative probability of …

Experimental Evaluation Of Several Key Factors Affecting Root Biomass Estimation By 1500 Mhz Ground-Penetrating Radar, John C. Bain, Frank P. Day, John R. Butnor

Biological Sciences Faculty Publications

Accurate quantification of coarse roots without disturbance represents a gap in our understanding of belowground ecology. Ground penetrating radar (GPR) has shown significant promise for coarse root detection and measurement, however root orientation relative to scanning transect direction, the difficulty identifying dead root mass, and the effects of root shadowing are all key factors affecting biomass estimation that require additional research. Specifically, many aspects of GPR applicability for coarse root measurement have not been tested with a full range of antenna frequencies. We tested the effects of multiple scanning directions, root crossover, and root versus soil moisture content in a …

Rapid Adaptive Responses To Climate Change In Corals, Gergely Torda, Jennifer M. Donelson, Manuel Aranda, Daniel J. Barshis, Line Bay, Michael L. Berumen, David G. Bourne, Neal Cantin, Sylvain Foret, Mikhail Matz

Biological Sciences Faculty Publications

Pivotal to projecting the fate of coral reefs is the capacity of reef-building corals to acclimatize and adapt to climate change. Transgenerational plasticity may enable some marine organisms to acclimatize over several generations and it has been hypothesized that epigenetic processes and microbial associations might facilitate adaptive responses. However, current evidence is equivocal and understanding of the underlying processes is limited. Here, we discuss prospects for observing transgenerational plasticity in corals and the mechanisms that could enable adaptive plasticity in the coral holobiont, including the potential role of epigenetics and coral-associated microbes. Well-designed and strictly controlled experiments are needed to …

Reproductive Competency And Mitochondrial Variation In Aged Syrian Hamster Oocytes, Fang Li, Frank J. Castora, Wentia Ford, Khalid Alarid, Howard W. Jones Jr., R. James Swanson

Biological Sciences Faculty Publications

The hamster is a useful model of human reproductive biology because its oocytes are similar to those in humans in terms of size and structural stability. In the present study we evaluated fecundity rate, ovarian follicular numbers, ova production, mitochondrial number, structure and function, and cytoplasmic lamellae (CL) in young (2–4 months) and old (12–18 months) Syrian hamsters (Mesocricetus auratus). Young hamsters had higher fertilisation rates and larger litters than old hamsters (100 vs 50% and 9.3 +/- 0.6 vs 5.5 +/- 0.6, respectively). Ovarian tissue from superovulated animals showed a 46% decrease in preantral follicles in old …

Biological Sciences Faculty Publications

Understanding the horizontal and vertical habitat of olive ridley sea turtles (Lepidochelys olivacea), a threatened species, is critical for determining regions for protection and relevant gear modifications that may effectively reduce bycatch, the largest threat to this species. Satellite transmitters were used to determine the movement and dive behavior of 21 female olive ridley turtles tagged in Pongara National Park, Gabon during the 2012, 2013, and 2015 nesting seasons. A switching state-space model was used to filter the tracking data and categorize the internesting and post-nesting movements. Gridded utilization distribution (UD) home range analysis of tracking data revealed …

Fundamental Principles Of Tremor Propagation In The Upper Limb, Andrew D. Davidson, Steven Knight Charles

Faculty Publications

Although tremor is the most common movement disorder, there exist few effective tremor-suppressing devices, in part because the characteristics of tremor throughout the upper limb are unknown. To clarify, optimally suppressing tremor requires a knowledge of the mechanical origin, propagation, and distribution of tremor throughout the upper limb. Here we present the first systematic investigation of how tremor propagates between the shoulder, elbow, forearm, and wrist. We simulated tremor propagation using a linear, time-invariant, lumped-parameter model relating joint torques and the resulting joint displacements. The model focused on the seven main degrees of freedom from the shoulder to the wrist …

A Continuous Time Model Of Centrally Controlled Motion With Random Switching Terms, J. C. Dallon, L C. Despain, E J. Evans, C P. Grant, Willaim V. Smith

Faculty Publications

This paper considers differential problems with random switching, with specific applications to the motion of cells and centrally coordinated motion. Starting with a differential-equation model of cell motion that was proposed previously, we set the relaxation time to zero and consider the simpler model that results. We prove that this model is well-posed, in the sense that it corresponds to a pure jump-type continuous time Markov process (without explosion). We then describe the model's long-time behavior, first by specifying an attracting steady-state distribution for a projection of the model, then by examining the expected location of the cell center when …

Statistical Shape And Intensity Modeling Of The Shoulder, Irene Sintini

Electronic Theses and Dissertations

Anatomical variability in the shoulder is inherently present and can influence healthy and pathologic biomechanics and ultimately clinical decision-making. Characterizing variation in bony morphology and material properties in the population can support treatment and specifically the design, via shape and sizing, of shoulder implants. Total Shoulder Arthroplasty (TSA) is the treatment of choice for glenohumeral osteoarthritis as well as bone fracture. Complications and poor outcomes in TSA are generally influenced by the inability of the implant to replicate the natural joint biomechanics and by the bone quality around the fixation features. For this reason, knowledge of bony morphology and mechanical …

Quantitating Active Photosystem Ii Reaction Center Content From Fluorescence Induction Transients, Cole D. Murphy, Guangyan Ni, Gang Li, Audrey Barnett, Kui Xu, Jessica Grant-Burt, Justin D. Liefer, David J. Suggett, Douglas A. Campbell

Michigan Tech Publications, Part 1

Photosystem II (PSII) is a pigment-protein complex that photochemically extracts electrons from water, generating the reductant that supports biological productivity in all biomes. Estimating the content of active PSII reaction centers in a liquid sample is a key input for estimating aquatic photosynthesis rates, as well as for analyzing phytoplankton stress responses. Established procedures for PSII content quantification based on oxygen evolution are slow, imprecise and require dense cell suspensions, and are thus inapplicable to many laboratory or field studies. A new approach uses baseline chlorophyll fluorescence emission divided by the effective absorbance cross section for PSII photochemistry, with both …

A Model Of Distress Tolerance In Self-Damaging Behaviors: Examining The Role Of Emotional Reactivity And Learned Helplessness, Brittany Kay Sommers

Dissertations

Problem

Although the literature is clear that low emotional distress tolerance is associated with a myriad of self-damaging behaviors, very little is known about individual difference factors in distress tolerance. Both theoretical and empirical support suggest that emotional reactivity and learned helplessness may be individual difference factors in distress tolerance. Specifically, individuals with high emotional reactivity and high learned helplessness may be at risk for low distress tolerance. Further research was needed to clarify the role of emotional reactivity and learned helplessness in distress tolerance in the context of self-damaging behaviors.

Method

Participants completed surveys which measured their (a) emotional …

Dissertations

Problem and Purpose

Much research over several decades has established the importance of ongoing professional learning for teachers and has identified what effective professional learning should look like. Little research has been done, however, on the professional learning practices of teachers in faith-based schools, and few studies have focused on the learning needs of millennial teachers, those newest to the profession.

This study explores the professional learning practices of educators in the Seventh-day Adventist School system in North America and the factors that impact those practices, with a special focus on millennial educators. Educational leaders can use the results of …

Resilience In Ecotoxicology: Toward A Multiple Equilibrium Concept, Mirco Bundschuh, Ralf Schulz, Ralf B. Schäfer, Craig R. Allen, David G. Angeler

School of Natural Resources: Faculty Publications

The term resilience describes stress-response patterns across scientific disciplines. In ecology, advances have been made to clearly define resilience based on underlying mechanistic assumptions. Engineering resilience (rebound) is used to describe the ability of organisms to recover from adverse conditions (disturbances), which is termed the rate of recovery. By contrast, the ecological resilience definition considers a systemic change, that is, when ecosystems reorganize into a new regime following disturbance. Under this new regime, structural and functional aspects change considerably relative to the previous regime, without recovery. In this context, resilience is an emergent property of complex systems. In the present …

Assessment Of A Channel Catfish Population In A Large Open River System, A. J. Blank, M. J. Hamel, Jonathan J. Spurgeon, Mark A. Pegg

School of Natural Resources: Faculty Publications

Estimates of dynamic rate functions for riverine channel catfish, Ictalurus punctatus (Rafinesque), populations are limited. The open nature and inherent difficulty in sampling riverine environments and the propensity for dispersal of channel catfish impede estimation of population variables. However, contemporary population models (i.e. robust design models) can incorporate the open nature of these systems. The purpose of this study was to determine channel catfish population abundance, survival and size structure and to characterize growth in the lower Platte River, Nebraska, USA. Annual survival estimates of adult channel catfish were 13%–49%, and channel catfish abundance estimates ranged from 8,281 to 24,261 …

The study outcomes were lifetime, recent, and in-school use of …

The Development And Validation Of The Secondary Trauma In Resident Assistants Scale, R. Jason Lynch

Educational Leadership & Workforce Development Faculty Publications

SECONDARY TRAUMATIC STRESS has been described as "the stress resulting from helping or wanting to help a traumatized or suffering person" (Figley, 1999, p. 10). College resident assistants often serve as first-responders to students who have experienced traumatic life events such as severe mental illness, substance abuse, sexual violence, and hate crimes. To date, the literature has not thoroughly addressed the impact of providing this level of support on collegiate resident assistants. This study aimed to explore one possible outcome identified in individuals in other helping professions: secondary traumatic stress. The researcher set out to develop and validate an instrument …

Biology Faculty Publications and Presentations

Background and Aims: The Western Antarctic Peninsula is one of the most rapidly warming regions on Earth, and many biotic communities inhabiting this dynamic region are responding to these well-documented climatic shifts. Yet some of the most prevalent organisms of terrestrial Antarctica, the mosses, and their responses to warming have been relatively overlooked and understudied. In this research, the impacts of 6 years of passive warming were investigated using open top chambers (OTCs), on moss communities of Fildes Peninsula, King George Island, Antarctica.

Methods: The effects of experimental passive warming on the morphology, sexual reproductive effort and stress physiology of …

Small Noncoding Rna Expression During Extreme Anoxia Tolerance Of Annual Killifish (Austrofundulus Limnaeus) Embryos, Claire L. Riggs, Jason E. Podrabsky

Biology Faculty Publications and Presentations

Small noncoding RNAs (sncRNA) have recently emerged as specific and rapid regulators of gene expression, involved in a myriad of cellular and organismal processes. MicroRNAs, a class of sncRNAs, are differentially expressed in diverse taxa in response to environmental stress, including anoxia. In most vertebrates, a brief period of oxygen deprivation results in severe tissue damage or death. Studies on sncRNA and anoxia have focused on these anoxia-sensitive species. Studying sncRNAs in anoxia-tolerant organisms may provide insight into adaptive mechanisms supporting anoxia tolerance. Embryos of the annual killifish Austrofundulus limnaeus are the most anoxia-tolerant vertebrates known, surviving over 100 days …

Reciprocal Legitimation In The Federal Courts System, Neil S. Siegel

Faculty Scholarship

Much scholarship in law and political science has long understood the U.S. Supreme Court to be the “apex” court in the federal judicial system, and so to relate hierarchically to “lower” federal courts. On that top-down view, exemplified by the work of Alexander Bickel and many subsequent scholars, the Court is the principal, and lower federal courts are its faithful agents. Other scholarship takes a bottom-up approach, viewing lower federal courts as faithless agents or analyzing the “percolation” of issues in those courts before the Court decides. This Article identifies circumstances in which the relationship between the Court and other …
