Design And Implementation Of An Open Framework For Ubiquitous Carbon Footprint Calculator Applications, Farzana Rahman, Casey O'Brien, Sheikh Iqbal Ahamed, He Zhang, Lin Liu

Mathematics, Statistics and Computer Science Faculty Research and Publications

As climate change is becoming an important global issue, more and more people are beginning to pay attention to reducing greenhouse gas emissions. To measure personal or household carbon dioxide emission, there are already plenty of carbon footprint calculators available on the web. Most of these calculators use quantitative models to estimate carbon emission caused by a user's activities. Although these calculators can promote public awareness regarding carbon emission due to an individual's behavior, there are concerns about the consistency and transparency of these existing CO₂ calculators. Apart from a small group of smart phone based carbon footprint calculator …

Don't Argue With The Members, Jaber F. Gubrium, James A. Holstein

Social and Cultural Sciences Faculty Research and Publications

Mel Pollner regularly cautioned researchers not to argue with the members of settings under consideration. He warned against substituting the researcher’s meaning for the meanings of those being studied. This article discusses facets of the caution as they relate to the research process. Seemingly simple, the tenet is nuanced in application. The article adds to the nuance by distinguishing what is called the “replacement” of meaning with the “displacement” of meaning, providing a way of understanding what members could mean if the contexts and settings of their accounts were taken into consideration.

Gendered Violence And The Ethics Of Social Science Research, Sameena A. Mulla, Heather R. Hlavka

Social and Cultural Sciences Faculty Research and Publications

The issue of ethical conduct in research settings is important and complex. As tenure-track researchers who study gendered violence, we found Clark and Walker’s discussion provocative, thoughtful, and interesting. They urge researchers to attend both to the structural dynamics of research carried out under the pressures of tenure and promotion while advocating an ethical frame that draws attention to the limited definition of risk or harm that animates typical human subjects research. Victims of violence, they argue, should not be subjected to a standardized understanding of risk. A broader framework is needed, one that brings into conversation virtue ethics with …

Different Motion Cues Are Used To Estimate Time-To-Arrival For Frontoparallel And Loming Trajectories, Finnegan J. Calabro, Scott A. Beardsley, Lucia M. Vaina

Biomedical Engineering Faculty Research and Publications

Estimation of time-to-arrival for moving objects is critical to obstacle interception and avoidance, as well as to timing actions such as reaching and grasping moving objects. The source of motion information that conveys arrival time varies with the trajectory of the object raising the question of whether multiple context-dependent mechanisms are involved in this computation. To address this question we conducted a series of psychophysical studies to measure observers’ performance on time-to-arrival estimation when object trajectory was specified by angular motion (“gap closure” trajectories in the frontoparallel plane), looming (colliding trajectories, TTC) or both (passage courses, TTP). We measured performance …

Quantifying The Tibiofemoral Joint Space Using X-Ray Tomosynthesis, Benjamin Kalinosky, John M. Sabol, Kelly Piacsek, Beth Heckel, Taly Gilat Schmidt

Biomedical Engineering Faculty Research and Publications

Purpose: Digital x-ray tomosynthesis (DTS) has the potential to provide 3D information about the knee joint in a load-bearing posture, which may improve diagnosis and monitoring of knee osteoarthritis compared with projection radiography, the current standard of care. Manually quantifying and visualizing the joint space width (JSW) from 3D tomosynthesis datasets may be challenging. This work developed a semiautomated algorithm for quantifying the 3D tibiofemoral JSW from reconstructed DTS images. The algorithm was validated through anthropomorphic phantom experiments and applied to three clinical datasets. Methods: A user-selected volume of interest within the reconstructed DTS volume was enhanced with 1D multiscale …

High Temperature Thermodynamic Properties Of Znte(S), Robert F. Brebrick

Mechanical Engineering Faculty Research and Publications

We have gathered the partial pressure, Knudsen cell, and emf measurements on ZnTe(s) from which the Gibbs energy of formation can be calculated. Published partial pressures of diatomic tellurium have been adjusted to take account of a subsequently published third law analysis of tellurium. The equation used to calculate the total pressure from the rate of mass loss from an extensive set of Knudsen cell measurements has been corrected to give a 5% increase in total pressure and the Gibbs energy of formation has been recalculated. A high temperature heat capacity for ZnTe(s) has been selected from the published data. …

Supervisor Self-Disclosure: Supervisees' Experiences And Perspectives, Sarah Knox, Lisa Edwards, Shirley A. Hess, Clara E. Hill

College of Education Faculty Research and Publications

Twelve graduate-level supervisees were interviewed regarding their experiences of supervisor self-disclosure (SRSD); data were analyzed using consensual qualitative research. When describing a specific SRSD experience, supervisees reported a range of antecedents (e.g., difficult clinical situation, self-doubt, tension in supervision relationship) followed by supervisor disclosures about clinical experiences or personal information. Supervisees perceived that their supervisors disclosed primarily to normalize, but also to build rapport and to instruct. The SRSDs had mostly positive effects (e.g., normalization), though some negative effects (e.g., deleterious impact on supervision relationship) were reported. Implications of these findings for supervision, training, and research are addressed.

The Effect Of Acceptance Training On Psychological And Physical Health Outcomes In Elders With Chronic Conditions, Patricia Mcdonald, Jaclene Zauszniewski, Abir K. Bekhet, Laura Dehelian, Diana L. Morris

College of Nursing Faculty Research and Publications

This pilot trial investigated the short and long-term effects of Acceptance Training (ACT) intervention on acceptance, perceived health, functional status, anxiety, and depression in elders with chronic conditions living in retirement communities (RCs). The ACT intervention combined Rational Emotive Behavior Therapy with music, relaxation, and guided imagery during six weekly 2-hour sessions. Face-to-face interviews were conducted with 16 African-American and 46 White elders across four data collection points in six randomly selected RCs using well-established measures of perceived health, functional status, anxiety, and depression, and a measure of acceptance of chronic conditions adapted from a previous measure of acceptance of …

Subtle Discrimination In The Rental Housing Market: Evidence From E-Mail Correspondence Of Landlords, Andrew Hanson, Zackary Hawley, Aryn Taylor

Economics Faculty Research and Publications

We find that landlords practice subtle discrimination in the rental housing market through the use of language associated with describing and viewing a unit, inviting further correspondence, making a formal greeting, and using polite language when replying to e-mail inquiries from a white name more often than to an African American name, they also send longer e-mails and respond quicker to white names.

A Comparison Of Adult- And Peer-Mediated Intervention For Autism: A Case Study, Maura Jones Moyle

Speech Pathology and Audiology Faculty Research and Publications

This study examined the response of a young child with autism to two play-based intervention conditions: adult-mediated and peer-mediated. The client was five years old, demonstrated moderate-to-severe autism, and exhibited developmental functioning between the 14 to 34 month level. The peer-mediated condition, based on a modified Integrated Play Group approach, utilized a typically developing peer who was three years of age. The study utilized an ABAB alternating treatment design to compare the impact of the adult- and peer-mediated interventions. Results from the current study suggest that the adult-mediated intervention resulted in increased engagement and more sophisticated social-communicative behaviors than the …

Race, Gender, And Tokenism In Policing: An Empirical Elaboration, Meghan S. Stroshine, Steven G. Brandl

Social and Cultural Sciences Faculty Research and Publications

According to tokenism theory, “tokens” (those who comprise less than 15% of a group’s total) are expected to experience a variety of hardships in the workplace, such as feelings of heightened visibility, isolation, and limited opportunities for advancement. In the policing literature, most previous studies have defined tokenism narrowly in terms of gender. The current research extends prior research by examining tokenism as a function of gender and race, with an examination of racial/ethnic subgroups. Particular attention is paid to Latino officers as this study represents the first known study of tokenism and Latino police officers. Quantitative analyses reveal that, …

(Wp 2011-10) Obituary: Warren J. Samuels (1933-2011), John Davis

Economics Working Papers

This paper examines the research and career of the late Warren J. Samuels (1933-2011), an influential institutionalist economist in the Wisconsin John Commons tradition and well-known historian and methodologist of economics. It discusses four main positions Samuels developed and held regarding the history of economic thought as intellectual history, the theory of economic policy, methodological pluralism, and the invisible hand doctrine. Among the views considered are: his matrix approach to meaningfulness, his characterization of intellectual systems, his emphasis on the centrality of the social order, his theory of economic policy as a neglected subject, his discourse analysis of language, his …

Flexibility In The Patterning And Control Of Axial Locomotor Networks In Lamprey, James T. Buchanan

Biological Sciences Faculty Research and Publications

In lower vertebrates, locomotor burst generators for axial muscles generally produce unitary bursts that alternate between the two sides of the body. In lamprey, a lower vertebrate, locomotor activity in the axial ventral roots of the isolated spinal cord can exhibit flexibility in the timings of bursts to dorsally-located myotomal muscle fibers versus ventrally-located myotomal muscle fibers. These episodes of decreased synchrony can occur spontaneously, especially in the rostral spinal cord where the propagating body waves of swimming originate. Application of serotonin, an endogenous spinal neurotransmitter known to presynaptically inhibit excitatory synapses in lamprey, can promote decreased synchrony of dorsal–ventral …

Identifying Polyglutamine Protein Species In Situ That Best Predict Neurodegeneration, Jason Miller, Montserrat Arrasate, Elizabeth Brooks, Clare Peter Libeu, Justin Legleiter, Danny Hatters, Jessica Curtis, Kenneth Cheung, Preethi Krishnan, Siddhartha Mitra, Kartika Widjaja, Benjamin A. Shaby, Gregor P. Lotz, Yvonne Newhouse, Emily M. Sontag, Alex Osmand, Michelle Gray, Vanitha Thulasiramin, Frederic Saudou, Mark Segal, X William Yang, Eliezer Masliah, Leslie M. Thompson, Paul J. Muchowski, Karl H. Weisgraber, Steven Finkbeiner

Biological Sciences Faculty Research and Publications

Polyglutamine (polyQ) stretches exceeding a threshold length confer a toxic function to proteins that contain them and cause at least nine neurological disorders. The basis for this toxicity threshold is unclear. Although polyQ expansions render proteins prone to aggregate into inclusion bodies, this may be a neuronal coping response to more toxic forms of polyQ. The exact structure of these more toxic forms is unknown. Here we show that the monoclonal antibody 3B5H10 recognizes a species of polyQ protein in situ that strongly predicts neuronal death. The epitope selectively appears among some of the many low-molecular-weight conformational states assumed by …

Mechanical Characterization Of Fourth Generation Composite Humerus, Prateek Grover, Carolyne Albert, Mei Wang, Gerald F. Harris

Biomedical Engineering Faculty Research and Publications

Mechanical data on upper extremity surrogate bones, supporting use as biomechanical tools, is limited. The objective of this study was to characterize the structural behaviour of the fourth-generation composite humerus under simulated physiologic bending, specifically, stiffness, rigidity, and mid-diaphysial surface strains. Three humeri were tested in four-point bending, in anatomically defined anteroposterior (AP) and mediolateral (ML) planes. Stiffness and rigidity were derived using load–displacement data. Principal strains were determined at the anterior, posterior, medial, and lateral surfaces in the humeral mid-diaphysial transverse plane of one specimen using stacked rosettes. Linear structural behaviour was observed within the test range. Average stiffness …

A New Genus Of Miniaturized And Pug-Nosed Gecko From South America (Sphaerodactylidae: Gekkota), Tony Gamble, Juan D. Daza, Guarino R. Colli, Laurie J. Vitt, Aaron M. Bauer

Biological Sciences Faculty Research and Publications

Sphaerodactyl geckos comprise five genera distributed across Central and South America and the Caribbean. We estimated phylogenetic relationships among sphaerodactyl genera using both separate and combined analyses of seven nuclear genes. Relationships among genera were incongruent at different loci and phylogenies were characterized by short, in some cases zero-length, internal branches and poor phylogenetic support at most nodes. We recovered a polyphyletic Coleodactylus, with Coleodactylus amazonicus being deeply divergent from the remaining Coleodactylus species sampled. The C. amazonicus lineage possessed unique codon deletions in the genes PTPN₁₂ and RBMX while the remaining Coleodactylus species had unique codon …

Perceptions Of Professional Practice And Work Environment Of New Graduates In A Nurse Residency Program, Marilyn Meyer Bratt, Holly M. Felzer

New nurses continue to face challenging work environments and high expectations for professional competence as they enter practice. Nurse residency programs are gaining prominence as a mechanism to ease new graduates’ transition to practice. This study examined new graduates’ perceptions of their professional practice competence and work environment throughout a yearlong nurse residency program. Employing a repeated measures design, data were collected at baseline, at 6 months, and at 12 months. Results showed that job satisfaction was significantly lowest at 6 months and highest at 12 months. Job stress was found to be lowest at 12 months and organizational commitment …

Prehabilitation Before Total Knee Arthroplasty Increases Strength And Function In Older Adults With Severe Osteoarthritis, Ann M. Swank, Joseph B. Kachelman, Wendy Bibeau, Peter M. Quesada, John Nyland, Arthur Malkani, Robert V. Topp

College of Nursing Faculty Research and Publications

Preparing for the stress of total knee arthroplasty (TKA) surgery by exercise training (prehabilitation) may improve strength and function before surgery and, if effective, has the potential to contribute to postoperative recovery. Subjects with severe osteoarthritis (OA), pain intractable to medicine and scheduled for TKA were randomized into a usual care (UC) group (n = 36) or usual care and exercise (UC + EX) group (n = 35). The UC group maintained normal daily activities before their TKA. The UC + EX group performed a comprehensive prehabilitation program that included resistance training using bands, flexibility, and step training at least …

Preparation, Properties, And Reactivity Of Carbonylrhodium(I) Complexes Of Di(2-Pyrazolylaryl)Amido-Pincer Ligands, Sarath Wanniarachchi, Brendan J. Liddle, Sergey V. Lindeman, James R. Gardinier

Chemistry Faculty Research and Publications

A series of six carbonylrhodium(I) complexes of three new and three previously reported di(2-3R-pyrazolyl)-p-Z/X-aryl)amido pincer ligands, (^RZX)Rh(CO), (R is the substituent at the 3-pyrazolyl position proximal to the metal; Z and X are the aryl substituents para- to the arylamido nitrogen) were prepared. The metal complexes were studied to assess how their properties and reactivities can be tuned by varying the groups along the ligand periphery and how they compared to other known carbonylrhodium(I) pincer derivatives. This study was facilitated by the discovery of a new CuI-catalyzed coupling reaction between 2-(pyrazolyl)-4-X-anilines (X = Me or …
