Resumes And Cover Letters: The Accuracy Of Extraversion Judgments Made From Resume And Cover Letter Biodata, Matthew Sean Christensen

Dissertations and Theses @ UNI

This following thesis study examined the accuracy of extraversion judgments accrued from resumes and cover letters. Within personnel selection, professionals often rely upon the applicant resume as an initial prescreening tool. Little empirical research, however, has explored whether reviewers use the resume and cover letter in a reliable fashion. Moreover, the current research base has not explored whether cover letters improve the accuracy of certain personality inferences made from resume biodata. Based upon the premises of Funder's (1995) Realistic Accuracy Model (RAM), the author posited that cover letters improve the accuracy of extraversion judgments made from resumes. The second intention …

Further Delineation Of The Role Of The Amygdala In Face Processing And Racial Categorization, Osman Afzal Chowdhry

Dissertations and Theses @ UNI

DNA exonerations in the legal system have increased steadily since 1989 from one or two per year to an average of 21 per year since 2001. A disquieting number of these exonerations originated from wrongful convictions following cross-racial identifications. Explaining the prevalence of erroneous cross-racial identifications centers on the Cross Race Effect (CRE), a phenomena whereby recognition for one's own race greatly outweighs recognition ability for other-race faces. Forty years of research in this area has produced a number of competing explanations. Recent neurological evidence has demonstrated separate neural regions for the processing of same-race and other-race faces as well …

Analysis Of N-Linked Oligosaccharides Of Prostate-Specific Antigen And Prostatic Acid Phosphatase In Prostatic Fluids, Krista Yaudes White

Theses and Dissertations in Biomedical Sciences

Presently, prostate cancer is the most common cancer afflicting men in the United States, with serum PSA being the "gold standard" protein biomarker used in the clinic for detecting and diagnosing prostate cancer. Nonetheless, serum PSA levels can also be elevated in non-cancerous conditions as well, such as benign prostatic hyperplasia (BPH). Due to this overlap, many unnecessary biopsies and radical prostatectomies occur, leading to patient distress. Despite recent advances to clinical assays which consider other clinical parameters, there is still a great need for improved clinical detection methodologies for prostate cancer, including improved biomarkers. Therefore, this research project aims …

Teacher-Child Relationships In Early Childhood Classrooms, Michelle Tuttle

Graduate Research Papers

The purpose of this review was to evaluate the existing evidence of child and teacher relationships in early childhood settings on children's academic performance. Relationships were examined between parent and child, childcare provider and child, and teacher and child. Parent-child and teacher-child relationships are interrelated. The relationships interact with one another and influence the way a child develops. Children found with quality parent and teacher relationships were better able to concentrate, explore the environment, and ask adults for help. Research also found that quality activities in the classroom promoted strong teacher-child relationships. Two types of instruction, direct instructions and child-centered, …

Multicast Encryption Infrastructure For Security In Sensor Networks, Richard R. Brooks, Brijesh Pillai, Matthew Pirretti, Michele C. Weigle

Computer Science Faculty Publications

Designing secure sensor networks is difficult. We propose an approach that uses multicast communications and requires fewer encryptions than pairwise communications. The network is partitioned into multicast regions; each region is managed by a sensor node chosen to act as a keyserver. The keyservers solicit nodes in their neighborhood to join the local multicast tree. The keyserver generates a binary tree of keys to maintain communication within the multicast region using a shared key. Our approach supports a distributed key agreement protocol that identifies the compromised keys and supports membership changes with minimum system overhead. We evaluate the overhead of …

Faculty Publications

The charm fragmentation function has been measured in D* photoproduction with the ZEUS detector at HERA using an integrated luminosity of 120 pb-1. The fragmentation function is measured versus z = (E +p||)D* /2Ejet, where E is the energy of the D * meson and p|| is the longitudinal momentum of the D * meson relative to the axis of the associated jet of energy Ejet. Jets were reconstructed using the kT clustering algorithm and required to have transverse energy larger than 9GeV. The D* meson associated with the jet was required to have a transverse momentum larger than 2GeV. …

What Do We Owe Future Generations?, Neil H. Buchanan

GW Law Faculty Publications & Other Works

In the United States, it is common for legal scholars, economists, politicians and others to claim that we are selfishly harming "our children and grandchildren" by (among many other things) running large government budget deficits. This article first asks two broad questions: (1) Do we owe future generations anything at all as a philosophical matter? and (2) If we do owe something to future generations, how should we balance their interests against our own? The short answers are "Probably" and "We really are not sure."

Finding only general answers to these general questions, I then look specifically at U.S. fiscal …

Development And Implementation Of Fully 3d Statistical Image Reconstruction Algorithms For Helical Ct And Half-Ring Pet Insert System, Daniel Keesing

All Theses and Dissertations (ETDs)

X-ray computed tomography: CT) and positron emission tomography: PET) have become widely used imaging modalities for screening, diagnosis, and image-guided treatment planning. Along with the increased clinical use are increased demands for high image quality with reduced ionizing radiation dose to the patient. Despite their significantly high computational cost, statistical iterative reconstruction algorithms are known to reconstruct high-quality images from noisy tomographic datasets. The overall goal of this work is to design statistical reconstruction software for clinical x-ray CT scanners, and for a novel PET system that utilizes high-resolution detectors within the field of view of a whole-body PET scanner. …

Electrocorticographic Neural Correlates Of Arm Movements And Associated Goal Orientation In Humans, Nicholas Anderson

All Theses and Dissertations (ETDs)

This thesis analyzed the cortical representation of arm kinematics, target encoding, and goal encoding using subdural electrocorticographic: ECoG) recordings in humans. Using a joystick-based visuomotor task, subjects performed both a standard, delayed match-to-sample center-out task as well as a circular tracing task. Spectral analyses of the ECoG signals clearly showed significant cosine tuning for hand velocity, direction, position and speed throughout the cortex. In particular, velocity tuning was best represented spectrally in a high gamma band from around 90-150 Hz in the primary motor cortical regions. In dorsolateral prefrontal cortex: DLPFC), cortical activity in the 150-250 Hz band of the …

Antibiotic Resistance Of Helicobacter Pylori Strains In The United Arab Emirates And Its Relation To The Gene Associated To Gastric Cancer “Cag A Gene”, Wafa Ali Rashid Al-Tayyari

Theses

Helicobacter pylori is a flagellated corkscrew, slow growing neutrophilic gram negative ureolytic organism. It has an extraordinary ability to establish infection in human stomach that can last for years or decades. Its eradication remains an important public health challenge especially in light of broadening indications and increasing antimicrobial resistance.

AIM: i) Identification of H. pylori in UAE patients ii) Determination of the prevalence of antibiotic resistance genes (mutation in 23S rRNA gene in clarithromycin, and deletion in RdxA gene in metronidazole) among H. pylori strains isolated from U.A.E patients by using molecular methods, iii) Ascertain whether Cag A- positive H. …

Filling Essential Laminations, Michael Hamm

All Theses and Dissertations (ETDs)

Thurston and, later, Calegari-Dunfield found superlaminations in certain laminated 3-manifolds, the existence of which implies inclusions into Homeo S1 of the fundamental groups of those manifolds. The present paper extends the construction of the superlamination, and finds an infinite class of manifolds to which the extension does not yield such an inclusion of groups. Specifically, Calegari and Dunfield's proof of the existence of such an inclusion into Homeo S1 depended on their filling lemma, which states that essential laminations with solid torus guts can have leaves added to them to yield essential laminations with solid torus complementary regions.: Roughly, a …

Connections Between Floer-Type Invariants And Morse-Type Invariants Of Legendrian Knots., Michael Henry

All Theses and Dissertations (ETDs)

We investigate existing Legendrian knot invariants and discover new connections between the theory of generating families, normal rulings and the Chekanov-Eliashberg differential graded algebra: CE-DGA). Given a Legendrian knot $\sK$ with generic front projection $\sfront$, we define a combinatorial/algebraic object on $\sfront$ called a \emph{Morse complex sequence}, abbreviated MCS. An MCS encodes a finite sequence of Morse homology complexes. Every suitably generic generating family for $\sfront$ admits an MCS and every MCS has a naturally associated graded normal ruling. In addition, every MCS has a naturally associated augmentation of the CE-DGA of the Ng resolution $\sNgres$ of the front $\sfront$. …

Ultraviolet Radiation Sensitivity In Cave Bacteria: Evidence Of Adaptation To The Subsurface?, Jessica R. Snider, Caitlin Goin, Robert V. Miller, Penelope J. Boston, Diana E. Northup

International Journal of Speleology

We hypothesize that a reduced capacity to withstand or repair cellular damage from ultraviolet radiation may be present in cave-adapted microorganisms that never experience such conditions. However, a small number of previous studies have shown that some subsurface bacteria do not show greater sensitivity to ultraviolet radiation (UVR) than surface bacteria. To estimate UVR sensitivity in cave bacteria, bacterial isolates were collected from Carlsbad Cavern, New Mexico, U.S.A., and percent survival following exposure to various UVC and UVA radiation doses was determined. Cave bacteria from Left Hand Tunnel in Carlsbad Cavern and surface bacteria from soil and rocks above Carlsbad …

Guanophilic Fungi In Three Caves Of Southwestern Puerto Rico, Ángel M. Nieves-Rivera, Carlos J. Santos-Flores, Frank M. Dugan, Thomas E. Miller

International Journal of Speleology

Fifty species of guanophilic (bat guano-loving) fungi were isolated from field-collected samples within three caves in southwestern Puerto Rico; most were mitosporic fungi (23 species). The caves studied were Cueva La Tuna (Cabo Rojo), Cueva de Malano (Sistema de Los Chorros, San Germán), and Cueva Viento (El Convento Cave-Spring System, Guayanilla-Peñuelas). The most conspicuous fungus by far was the zygomycete Circinella umbellata (Mucorales). Circinella umbellata dominated the bat guano incubation chambers (Petri dishes lined with sterile filter paper moistened with sterile water) at ambient laboratory conditions. Nineteen species of basidiomycetes (e.g., Ganoderma cf. resinaceum, Geastrum cf. minimum, Lepiota …

Microscopic Fungi Isolated From The Domica Cave System (Slovak Karst National Park, Slovakia). A Review, Alena Nováková

International Journal of Speleology

A broad spectrum, total of 195 microfungal taxa, were isolated from various cave substrates (cave air, cave sediments, bat droppings and/or guano, earthworm casts, isopods and diplopods faeces, mammalian dung, cadavers, vermiculations, insect bodies, plant material, etc.) from the cave system of the Domica Cave (Slovak Karst National Park, Slovakia) using dilution, direct and gravity settling culture plate methods and several isolation media. Penicillium glandicola, Trichoderma polysporum, Oidiodendron cerealis, Mucor spp., Talaromyces flavus and species of the genus Doratomyces were isolated frequently during our study. Estimated microfungal species diversity was compared with literature records from the same …

Microbial Communities And Associated Mineral Fabrics In Altamira Cave, Spain, Soledad Cuezva, Sergio Sanchez-Moral, Cesareo Saiz-Jimenez, Juan Carlos Cañaveras

International Journal of Speleology

Evidences of microbial colonizations were observed in Altamira Cave, Spain. These consisted of distinct small coloured colonies, both on walls and ceiling, mainly located in the area near the cave entrance, which progressed until reaching the Polychromes Hall. The colonizations were characterized by a high morphological and microstructural variability and related to biomineralization processes. Two main types of CaCO₃ deposits were related to the colonies: rosette- or nest-like aggregates of rhombohedral calcite crystals, and spheroid to hemispheroid CaCO₃ elements. Colonies distribution seems to be controlled by microenvironmental conditions inside the cavity. The areas of the cave showing higher …

The Association Between Bubble Trails And Folia: A Morphological And Sedimentary Indicator Of Hypogenic Speleogenesis By Degassing, Example From Adaouste Cave (Provence, France), Philippe Audra, Ludovic Mocochain, Jean-Yves Bigot, Jean-Claude Nobécourt

International Journal of Speleology

Bubble trails are subaqueous features in carbonate caves, which are made by the corrosion of ascending carbon dioxide bubbles. Folia are calcite deposits resembling inverted rimstone dams in saturated pools. Based on morphological studies in Adaouste Cave (Provence, France) and on studies elsewhere in the world, we propose a new genetic model for folia, close to the model of Green (1991). The association of bubble trails and folia, occurring on overhanging walls, is interpreted to be an indicator of hypogenic degassing occurring just below the water table. The association is the result of juxtaposed processes composed of corrosion along bubble …

A Terminological Matter: Paragenesis, Antigravitative Erosion Or Antigravitational Erosion?, Giancarlo Pasini

International Journal of Speleology

In the speleological literature three terms are utilized to designate the “ascending erosion”: paragenesis (= paragénésis, coined in 1968), antigravitative erosion (= erosione antigravitativa, coined in 1966) and antigravitational erosion (wrong English translation of the Italian term erosione antigravitativa, utilized later on). The term paragenesis should be abandoned because of the priority of the term erosione antigravitativa - on the ground of the “law of priority” – and because of its ambiguous etimology. On the other hand, the term antigravitational erosion should be forsaken in favour of the term antigravitative erosion, given the meaning that the terms gravitation and gravity …

Cryogenic Cave Carbonates From The Cold Wind Cave, Nízke Tatry Mountains, Slovakia: Extending The Age Range Of Cryogenic Cave Carbonate Formation To The Saalian, Karel Žák, Helena Hercman, Monika Orvošová, Ivana Jačková

International Journal of Speleology

Cold Wind Cave, located at elevations ranging between 1,600 and 1,700 m a. s. l. in the main range of the Nízke Tatry Mountains (Slovakia), is linked in origin with the adjacent Dead Bats Cave. Together, these caves form a major cave system located within a narrow tectonic slice of Triassic sediments. Both caves have undergone complex multiphase development. A system of sub-horizontal cave levels characterized by large, tunnel-like corridors was formed during the Tertiary, when elevation differences surrounding the cave were less pronounced than today. The central part of the Nízke Tatry Mountains, together with the cave systems, was …

Observations On The Cave-Associated Beetles (Coleoptera) Of Nova Scotia, Canada, Max Moseley

International Journal of Speleology

The cave-associated invertebrates of Nova Scotia constitute a fauna at a very early stage of post-glacial recolonization. The Coleoptera are characterized by low species diversity. A staphylinid Quedius spelaeus spelaeus, a predator, is the only regularly encountered beetle. Ten other terrestrial species registered from cave environments in the province are collected infrequently. They include three other rove-beetles: Brathinus nitidus, Gennadota canadensis and Atheta annexa. The latter two together with Catops gratiosus (Leiodidae) constitute a small group of cave-associated beetles found in decompositional situations. Quedius s. spelaeus and a small suite of other guanophiles live in accumulations of …

Deeply virtual Compton scattering, γ*p→γp has been measured in e+p collisions at HERA with the ZEUS detector using an integrated luminosity of 61.1 pb-1. Cross sections are presented as a function of the photon virtuality, Q2, and photon-proton centre-of-mass energy, W, for a wide region of the phase space, Q2 > 1.5GeV2 and 40 < W < 170GeV. A subsample of events in which the scattered proton is measured in the leading proton spectrometer, corresponding to an integrated luminosity of 31.3 pb-1, is used for the first direct measurement of the differential cross section as a function of t, where t is the square of the four-momentum transfer at the proton vertex. © SISSA 2009.

Measurement Of Beauty Photoproduction Using Decays Into Muons In Dijet Events At Hera, S. Chekanov, M. Derrick, S. Magill, B. Musgrave, D. Nicholass, J. Repond, R. Yoshida, Margarita C. K.

Faculty Publications

Beauty photoproduction in dijet events has been measured at HERA with the ZEUS detector using an integrated luminosity of 126 pb-1. Beauty was identified in events with a muon in the final state by using the transverse momentum of the muon relative to the closest jet. Lifetime information from the silicon vertex detector was also used; the impact parameter of the muon with respect to the primary vertex was exploited to discriminate between signal and background. Cross sections for beauty production as a function of the muon and the jet variables as well as dijet correlations are compared to QCD …

Investigating The Relationship Between Teacher Self-Efficacy Beliefs In Mathematics And Teacher Reflection: Do Teacher Thinking Dispositions Play A Moderating Role?, Shawna Hufendick

Dissertations and Theses @ UNI

Previous research has shown a relationship between teacher reflection and teacher acceptance of reform curricula. This study looked at the relationship between the variables of teacher self efficacy and teacher reflection, as they might relate to teacher attitudes towards instructional change. This study also looked at whether teacher thinking dispositions moderate this relationship. First and second grade teachers (N=l6) participating in a professional development opportunity in mathematics completed an efficacy measure, a thinking dispositions measure, and kept a journal to reflect after mathematics lessons taught. The teacher efficacy, thinking disposition, and journal reflection data was analyzed to see whether relationships …
