The dependence of dijet production on the virtuality of the exchanged photon, Q2, has been studied by measuring dijet cross sections in the range 0 ≲ Q2 < 2000 GeV2 with the ZEUS detector at HERA using an integrated luminosity of 38.6 pb-1. Dijet cross sections were measured for jets with transverse energy ETjet > 7.5 and 6.5 GeV and pseudorapidities in the photon-proton centre-of-mass frame in the range -3 < jet < 0. The variable xγobs, a measure of the photon momentum entering the hard process, was used to enhance the sensitivity of the measurement to the photon structure. The Q2 dependence of the ratio of low- to high-xγobs events was measured. Next-to-leading-order QCD predictions were found to generally underestimate the low-xγobs contribution relative to that at high xγobs. Monte Carlo models based on leading-logarithmic parton-showers, using a partonic structure for the photon which falls smoothly with increasing Q2, provide a qualitative description of the data. © Springer-Verlag / Società Italiana di Fisica 2004.

A resonance search has been made in the D*±p∓ invariant-mass spectrum with the ZEUS detector at HERA using an integrated luminosity of 126 pb-1. The decay channels D*+ -→ D0πs+ → (K -π+)πs+ and D*+ → D0πs+ → (K-π+π+π-) πs+ (and the corresponding antiparticle decays) were used to identify D*± mesons. No resonance structure was observed in the D*± p∓ mass spectrum from more than 60 000 reconstructed D*± mesons. The results are not compatible with a report of the H1 Collaboration of a charmed pentaquark, Θc0. © Springer-Verlag / Società Italiana di Fisica 2004.

The ZEUS detector has been used to study dissociation of virtual photons in events with a leading proton, γ*p → Xp, in e+p collisions at HERA. The data cover photon virtualities in two ranges, 0.03 < Q2 < 0.60 GeV2 and 2 < Q2 < 100 GeV2, with MX > 1.5 GeV, where MX is the mass of the hadronic final state, X. Events were required to have a leading proton, detected in the ZEUS leading proton spectrometer, carrying at least 90% of the incoming proton energy. The cross section is presented as a function of t, the squared four-momentum transfer at the proton vertex, Φ, the azimuthal angle between the positron scattering plane and …

Ic138 Is A Wd-Repeat Dynein Intermediate Chain Required For Light Chain Assembly And Regulation Of Flagellar Bending, Triscia W. Hendrickson, Catherine A. Perrone, Paul Griffin, Kristin Wuichet, Joshua Mueller, Pinfen Yang, Mary E. Porter, Winfield S. Sale

Biological Sciences Faculty Research and Publications

Increased phosphorylation of dynein IC IC138 correlates with decreases in flagellar microtubule sliding and phototaxis defects. To test the hypothesis that regulation of IC138 phosphorylation controls flagellar bending, we cloned the IC138 gene. IC138 encodes a novel protein with a calculated mass of 111 kDa and is predicted to form seven WD-repeats at the C terminus. IC138 maps near the BOP5 locus, and bop5-1 contains a point mutation resulting in a truncated IC138 lacking the C terminus, including the seventh WD-repeat. bop5-1 cells display wild-type flagellar beat frequency but swim slower than wild-type cells, suggesting that bop5-1 is altered in …

A Cognitive-Behavioral Treatment For Depression In Native American Middle-School Students, Lori B. Listug-Lunde

Theses and Dissertations

Depression and suicide are serious conditions among Native American adolescents. Despite the need for effective treatment approaches in this population, there continues to be a dearth of empirical research in this area. Intervention studies examining Native American adults at risk for depression and Native American youth at risk for suicide have found effectiveness utilizing group skill-based interventions. Group cognitive-behavioral therapy has demonstrated effectiveness among Caucasian adolescents; however, its effectiveness has never been examined with Native American youth experiencing depressive symptoms.

The current study modified, implemented, and evaluated a cognitive-behavioral intervention for depression among Native American middle-school students. A modification of …

Transitioning From Graduate Nurse To Professional Nurse, Jan M. Kamphuis

Theses and Dissertations

Just as the world is facing many changes and transitions, nursing care delivery systems and nursing education systems continue to struggle with significant transitions in nursing practice. New, or novice nurses, find it increasingly difficult to transition from the role of the graduate nurse to professional nurse. It is, therefore, not surprising that the most stressful time during a nurse's career is the first three months of initial employment or that 35% to 60% of nurse graduates change jobs during the first year of employment. Many of these new nurses suffer from early disillusionment with the profession and often leave …

Making A Case For Engaging Adolescents In Program Decision-Making, Jonathan R. Olson, H Wallace Goddard, Catherine A. Solheim, Lisa Sandt

Journal of Extension

The study discussed here examined the degree to which adolescents believe they are involved in community decision-making and examined discrepancies between adult and adolescent perceptions of common youth problems. Perceptual data were compared to adolescents' self-reported behavioral data to determine if perceptions diverge from reports of actual behaviors. Results indicate that many adolescents do not believe that their thoughts are considered valuable by decision-makers. However, differences in perceptions among adults and youth suggest that adolescent perceptions should be considered. Specifically, adults were particularly aware of adolescent behaviors with observable consequences, but adolescents were more aware of internal psychological problems.

Developing A Heritage Festival, Robert F. Brzuszek

Journal of Extension

The remarkable shift in the U.S. from rural to urban life does not come without social consequences. Many of the learned skills and trades associated with farming and rural life are now becoming lost to the majority of the U.S. population. One way of continuing traditional knowledge and skills is by offering hands-on demonstrations through a community heritage festival. This article describes Mississippi's community-based Piney Woods Heritage Festival.

This study suggests, but does not completely support, the potential use of Personal Data Assistants with patients with Traumatic Brain Injury.

The Kinetics Following Photolysis Of Nitrosyl Bromide, Lori A. Mahoney

Theses and Dissertations

One candidate for the development of a tunable laser in the mid-infrared for use as a defensive countermeasure against passive sensors exploits the nitric oxide (NO) transition at 5.4 μm. However, the difficulty with this mechanism is that when bromine (Br₂) and NO are present in a mixture, nitrosyl bromide (BrNO) is also created. The absorption bands present in BrNO complicate the design of such a laser. This thesis determines the forward and reverse rate constants of the reaction of Br₂ and NO to form BrNO following the photolysis of BrNO using Fourier Transform Infrared absorption spectroscopy. …

Underrepresented Doctoral Students: The Cultural And Institutional Barriers That Hinder Their Ability To Graduate, Nancy Greer-Williams

Dissertations

African American, Hispanic/Latino, and American Indian doctoral students continue to have attrition rates substantially higher than their White counterparts (Lovitts, 2001). Attrition was defined as the act of weakening or exhausting by constant harassment, abuse, or attack (Merriam-Webster, 2004). Research todate on this topic has focused on causes and barriers that can be attributed to mainstream groups, not on particular cultural barriers that may adversely affectdoctoral persistence among underrepresented groups. This study collected the lived experiences of these students at three separate university settings and turned them into conceptualized statements in an effort to understand the meaning of their experiences …

Ebxml: Global Standard For Electronic Business, Sujatha Babu

Student Work

Business-to-business integration is transforming the market and has already begun to increase the efficiency of those companies involved. EDI (Electronic Document Interchange) became very popular during 1970’s; Today EDI transactions total about $750 billion year. EDI is being used by 90% of Fortune 1000 companies. It has indeed become a dominant technology for the largest companies, on the other hand it has been adopted by less than 5% of small and medium sized companies in general and, of these, many use EDI only because their larger customers require it. The reason behind is that EDI is a difficult, complex technology …

Telecommunication, Regulation And Economic Development In Botswana: A Quantitative Analysis, Thapedi Kgodungwe

Student Work

This study is a quantitative analysis of the relationship between telecommunication infrastructure and economic development in Botswana from 1995 to 2003. The study used Gross Domestic Product (GDP) per capita as a measure for economic development and telephones per 100 people as a measure for telecommunications. A statistical correlation test was used to analyze the relationship between telecommunications and economic growth. The results of the analysis found that the two are significantly related. Looking at the results of this study, they reaffirmed the claim made by numerous previous researchers that indeed telecommunications is positively linked to economic development. However, it …
