How Leaders And Employees Experience, Make Sense Of, And Find Meaning In Humility, David Perryman
How Leaders And Employees Experience, Make Sense Of, And Find Meaning In Humility, David Perryman
Theses & Dissertations
By just about any measure, organizations today are more dynamic, diverse, and interdependent than at any other time in history. This environment puts unprecedented pressure on the human capacity to lead. And still, we demand more from our leaders—even as employees experience rising stress levels, declining loyalty, and deteriorating trust in their employers, and organizations face historically high rates of employee turnover along with the resulting financial and emotional costs. Clinging to romanticized notions of the larger-than-life leader blinds us to the paradoxical promise of humility; namely, that a leader’s greatest strength may lie, ironically, in the ability …

Deep Learning For Screening Covid-19 Using Chest X-Ray Images, Sanhita Basu, Sushmita Mitra, Nilanjan Saha
Deep Learning For Screening Covid-19 Using Chest X-Ray Images, Sanhita Basu, Sushmita Mitra, Nilanjan Saha
ISI Best Publications
With the ever increasing demand for screening millions of prospective 'novel coronavirus' or COVID-19 cases, and due to the emergence of high false negatives in the commonly used PCR tests, the necessity for probing an alternative simple screening mechanism of COVID-19 using radiological images (like chest X-Rays) assumes importance. In this scenario, machine learning (ML) and deep learning (DL) offer fast, automated, effective strategies to detect abnormalities and extract key features of the altered lung parenchyma, which may be related to specific signatures of the COVID-19 virus. However, the available COVID-19 datasets are inadequate to train deep neural networks. Therefore, …

Repair Strategies In Consecutive Interpreting: Comparing Professional Interpreters And Interpreting Trainees, Fang Tang
International Journal of Interpreter Education
This empirical study investigates features of interpreters’ use of repair strategies in Chinese-English consecutive interpreting. The data were collected from a consecutive interpreting experiment in which nine professional interpreters and nine interpreting trainees (all native speakers of Chinese with English as their B language) were invited to interpret an authentic speech from Chinese into English. A parallel bilingual corpus was built comprising transcripts of the speech and the interpreting output. All the repair strategies therein were coded for analysis. Follow-up interviews were conducted to elicit interpreters’ recall of their adoption of such strategies. Results show that in general, professional interpreters …
From International Borders To The Honeycombing Of Internal Borders: Response To Covid-19 Pandemic, David E. Toohey
From International Borders To The Honeycombing Of Internal Borders: Response To Covid-19 Pandemic, David E. Toohey
International Journal of Peace Studies
This article looks at borders during the Covid-19 crisis. In particular, it looks at how internal borders have arisen following xenophobic and national responses to Covid-19. This rise of internal borders is referred to as the honeycombing of borders. This article takes a genealogical approach to understand how borders have arisen—despite not always favorable opinions about them. Therefore, this looks at Rancière’s (1999; 2004) concept of the “police order” in the imposition of the sensible through Foucault’s genealogical approach, both to show the temporary, haphazard nature of these borders and how they revert to less desirable things. This is situated …

Deaf Women’S Health Vocabulary: Challenges For Interpreters Working In A Language Of Limited Diffusion, George Major, Rachel Mckee
Deaf Women’S Health Vocabulary: Challenges For Interpreters Working In A Language Of Limited Diffusion, George Major, Rachel Mckee
International Journal of Interpreter Education
Interpreters are aware that signed languages often do not have ‘established’ vocabulary for specialized topic domains, including topics that may occur regularly in situations that require interpreting. Healthcare is one such domain where interpreters are often challenged for equivalent signed language vocabulary or ways to communicate about the details of physical conditions, processes and treatments. Motivated by this practice reality, this study analyzed a corpus of deaf New Zealand Sign Language users’ accounts of women’s health-related experiences, to examine the language forms they used to communicate such topics. In this article, we present an analysis of how deaf women express …

Human Parsing Based Texture Transfer From Single Image To 3d Human Via Cross-View Consistency, Fang Zhao, Shengcai Liao, Kaihao Zhang, Ling Shao
Human Parsing Based Texture Transfer From Single Image To 3d Human Via Cross-View Consistency, Fang Zhao, Shengcai Liao, Kaihao Zhang, Ling Shao
Machine Learning Faculty Publications
This paper proposes a human parsing based texture transfer model via cross-view consistency learning to generate the texture of 3D human body from a single image. We use the semantic parsing of human body as input for providing both the shape and pose information to reduce the appearance variation of human image and preserve the spatial distribution of semantic parts. Meanwhile, in order to improve the prediction for textures of invisible parts, we explicitly enforce the consistency across different views of the same subject by exchanging the textures predicted by two views to render images during training. The perceptual loss …
Delimiting Cryptic Morphological Variation Among Human Malaria Vector Species Using Convolutional Neural Networks, Jannelle Couret, Danilo C. Moreira, Davin Bernier, Aria Mia Mia Loberti, Ellen M. Dotson, Marco Alvarez
Delimiting Cryptic Morphological Variation Among Human Malaria Vector Species Using Convolutional Neural Networks, Jannelle Couret, Danilo C. Moreira, Davin Bernier, Aria Mia Mia Loberti, Ellen M. Dotson, Marco Alvarez
Computer Science and Statistics Faculty Publications
Deep learning is a powerful approach for distinguishing classes of images, and there is a growing interest in applying these methods to delimit species, particularly in the identification of mosquito vectors. Visual identification of mosquito species is the foundation of mosquito-borne disease surveillance and management, but can be hindered by cryptic morphological variation in mosquito vector species complexes such as the malaria-transmitting Anopheles gambiae complex. We sought to apply Convolutional Neural Networks (CNNs) to images of mosquitoes as a proof-of-concept to determine the feasibility of automatic classification of mosquito sex, genus, species, and strains using whole-body, 2D images of mosquitoes. …

In this project, the author aimed to examine law enforcement officer attitude and behavior toward individuals with serious mental illness. There were two distinct sections of this project; one quantitative and one qualitative. For the quantitative portion, one hundred fifty four (N = 154) officers completed an online questionnaire providing information on their attitude toward individuals with serious mental illness in a variety of contexts. The questionnaire also generated information regarding officers’ general knowledge of mental illness, their level of contact with individuals with mental illness, and their desired social distance from individuals with mental illness. In the qualitative portion, …
Editing The Double Bass Concerto Of Antonio Scontrino, Roberto Pineda
Editing The Double Bass Concerto Of Antonio Scontrino, Roberto Pineda
Dissertations
Antonio Scontrino (1850-1922) was an important Italian Romantic composer, virtuoso double bassist, and respected pedagogue who is relatively unknown outside of the Italian musical community. His compositional output is prolific and includes string quartets, operas, symphonies, concerti, solo pieces, songs, and religious works. Indeed, Scontrino was a compelling composer who deserves more attention from the international musical community. In addition to his compositional expertise, he was an artful double bass performer whose works for the instrument, while distinctly idiomatic, are compositions of high quality.
This dissertation provides a description of the composer’s life and the events that transpired around Scontrino …
Traits Of Character That Facilitate Formation Of Exemplary Nurses In Bachelor Of Science Nursing Programs, Jean Marks
Traits Of Character That Facilitate Formation Of Exemplary Nurses In Bachelor Of Science Nursing Programs, Jean Marks
Dissertations
Constructivist grounded theory methods were applied in this study to explore traits of character that facilitate the formation of exemplary nurses in Bachelor of Science Nursing (BSN) programs. Interest in this study was prompted by a desire to examine attributes beyond academics alone that contribute to the formation of excellent nurses. The intent was to promote clarity in describing these attributes for further scholarly discussion.
Framing this study was Aristotle’s doctrine of the golden mean (Aristotle, 350 B.C.E./1934). Operational definitions consistent with this doctrine were created for the concepts of character, character traits, and exemplary nursing practice. The concept …
Childbirth And Control Behind Bars: A Descriptive Qualitative Analysis Of The Maternal Perception Of Control In Women Who Have Given Birth While Incarcerated, Lorin Raines
Dissertations
The perception of control during childbirth has been widely studied in various setting and groups. Many factors have been found to aid or impede the perception of control for birthing women. Significance of that perception of control during childbirth has also been measured in past studies. This descriptive qualitative study advances the knowledge of the perception of control during childbirth and examines a population that has thus far been excluded. Four previously incarcerated women participated in semi-structured interviews about their experience of giving birth while incarcerated and their perception of control during that time. The women were from diverse backgrounds …
Hemodynamic Response During Sedentary Behavior In Black/African American And White Males, Raymond Jones
Hemodynamic Response During Sedentary Behavior In Black/African American And White Males, Raymond Jones
Dissertations
Emerging evidence suggests that uninterrupted sitting has a deleterious impact on hemodynamics, namely a reduction in blood-flow induced shear stress in peripheral vessels, which leads to vascular dysfunction and increased arterial stiffness. Few studies have examined the cerebrovascular response, and no studies have discerned potential racial differences on the hemodynamic response to uninterrupted sitting. Purpose: To examine racial differences in the hemodynamic response during an acute period (1-hour) of uninterrupted sitting between Black/African American and White males. Methods: Twenty-four adult males (50% Black/African American) between the ages of 18 and 35 years and relatively healthy (i.e., free of …

Transformers: The Relationship Between Instructor And Course Persistence Among Community College Students, Jairus L. Johnson
Dissertations
U.S. community colleges play a unique role in providing higher education opportunities for members of society and are often viewed as the gateway to a post-secondary education (Savi, 2011). Two-year colleges foster a robust mission that is supported by a variety of curricular functions that tailor to a diverse student population. Furthermore, through an open-door policy, admittance only requires a high school diploma or equivalent. The aforementioned factors have created inherent challenges associated with student persistence, institutional retention, program completion, and graduation rates among community colleges. As compared to universities, community colleges have lower graduation and retention rates.
Researchers suggest …
An Examination Of The Influence Of Multi-Scale Processes And Connectivity On The Population And Assemblage Dynamics Of Headwater Fishes, Josh P. Hubbell
An Examination Of The Influence Of Multi-Scale Processes And Connectivity On The Population And Assemblage Dynamics Of Headwater Fishes, Josh P. Hubbell
Dissertations
Typified by their branching pattern, headwaters are numerically abundant as the density of these habitats increases with increasing distance from the base of a dendritic river system. Connectivity among headwaters is complex, resulting in the spatial isolation of populations. Headwater specialists have evolved a suite of traits that permit these species to permanently reside within these habitats. The spatial configuration and connectivity of headwaters has repercussions for metapopulations and meta-assemblages. I investigated how multi-scale processes and connectivity influenced the patch occupancy, coexistence, movement ecology, population structure, and gene flow of headwater specialists. In chapter two, I used occupancy modeling to …

College of Natural and Applied Sciences
The Keplerspacecraft observed the hot subdwarf star PHL 417 during its extended K2mission, and the high-precision photometric light curve reveals the presence of 17 pulsation modes with periods between 38 and 105 min. From follow-up ground-based spectroscopy, we find that the object has a relatively high temperature of 35 600 K, a surface gravity of log g/cm s−2 = 5.75 and a supersolar helium abundance. Remarkably, it also shows strong zirconium lines corresponding to an apparent +3.9 dex overabundance compared with the Sun. These properties clearly identify this object as the third member of the rare group of pulsating heavy-metal …
