The Impact Of "Fair Use" In The Higher Education Community: A Necessary Exception?, Oren R. Griffin, Stephana I. Colbert

Articles, Chapters in Books and Other Contributions to Scholarly Works

Despite legislative efforts to define it, the concept of Fair Use has been the subject of aggressive debate among publishers, authors, librarians, and users of copyrighted information ("academics") at academic institutions. With the advent of the Internet and the prospect of multimedia projects, the debate has intensified and expanded into the international community.

This Article focuses primarily on the challenges that face academic administrators and college and university attorneys seeking to advise their academic clients of the parameters of the Fair Use Doctrine-encouraging both sharing and dissemination of scholarly information, and compliance with the law, while limiting institutional liability. This …

A Description Of The Instructional And Assessment Practices Of Selected Elementary Teachers., Mary D. Morris

Graduate Theses, Dissertations, and Problem Reports (ETD)

Three distinct teachers, recognized by their administrators as excellent, were chosen to participate in a study designed to describe a recent phenomena in education. All three teachers were members of a faculty that was recognized as a Professional Development School in collaboration with the Benedum Foundation. Traditionally educators have looked to their local school district to provide continuing education. This professional development covers a wide range of topics and is given with a random approach. Recently there have been schools that have decided that their instruction and assessment could change to incorporate more alternative methods to accommodate a variety of …

Economies Of Scale, Overcapitalization And Asset Pricing In The United States Electric Utility Industry., Russell Rhine

Graduate Theses, Dissertations, and Problem Reports (ETD)

The following dissertation is the consolidation of three research projects in the U.S. electric utility industry. The first essay tests for scale economies in the electric utility industry using a panel data set of fossil fuel and nuclear fuel utilities. In addition, a variable cost function is used as opposed to a total cost function because the assumption of cost minimizing production inputs is not met. That is, electric utilities are overcapitalized. Therefore, the optimal capital stock is estimated and an estimate of economies of scale is generated. Evidence suggests that firms are operating on the negatively sloped portion of …

Evaluation Of The Flow Theory In Whitewater Kayaking., Christopher Douglass Jones

Graduate Theses, Dissertations, and Problem Reports (ETD)

The validation of the flow theory in an on-site whitewater setting is examined. A-priori hypotheses emphasized 3 concerns: (1) the relationship between a four channel model of flow and specific levels of flow indicators, (2) differences in the explanatory power of the four channel model and an original model of flow, and (3) the relationship between river difficulty and the frequencies of four channels (flow, anxiety, apathy, and boredom). On-site experiences of 52 whitewater kayakers were assessed with a series of single page questionnaires administered in the Cheat River Canyon in West Virginia. Sampling techniques involved a modification of the …

The use of computer hardware and software technology in schools is on the rise while there are increasing demands for success in mathematics by all students, despite diverse backgrounds. The problem is to determine the characteristics of students who most benefit from the use of spreadsheet software as a cognitive tool to assist them as they learn to organize and analyze data. For a period of six weeks, 114 seventh grade students received standard instruction in their mathematics classes in basic statistics/data analysis content. Concurrently, in a separate computer class, the students received instruction which focused on the use of …

The Cave Exploration Group Of East Africa And Volcanic Caves In Kenya, Michael Declan Kennedy

International Journal of Speleology

This paper looks at the history of the Cave Exploration Group of East Africa with special reference to the exploration of volcanic caves. It demonstrates that the group has concentrated on two main areas, the Chyulu HiIls and Mt. Suswa, although other areas have also been studied. The Cave Exploration Group of East Africa has had to cope with various problems. The most important of which are related to the socio-economic conditions of a developing country. These problems have not prevented the group from making a valuable contribution to vulcanospeleology.

"Hades" - A Remarkable Cave On Oldoinyo Lengai In The East African Rift Valley, Gordon J. Davies

International Journal of Speleology

Oldoinyo Lengai is the world’s only active carbonatite volcano, situated in northern Tanzania within the Eastern Rift Valley, al 2.751 degrees S, 35.902 degrees E. It forms an isolated symmetrical cone at the southern end of Lake Natron, with a summit elevation of 2,890 m (9,480 ft). Periodic eruptions of ash and lava have been recorded since about 1880, and with increasing precision during this century since 1904. In 1990 a routine expedition to monitor activity levels at the summit led to the discovery of a remarkable cave located in the crater floor, filled with numerous long delicate pale yellow …

This paper presents the first analysis of diffractive photon dissociation events in deep inelastic positron-proton scattering at HERA in which the proton in the final state is detected and its momentum measured. The events are selected by requiring a scattered proton in the ZEUS leading proton spectrometer (LPS) with xL > 0.97, where xL is the fraction of the incoming proton beam momentum carried by the scattered proton. The use of the LPS significantly reduces the contamination from events with diffractive dissociation of the proton into low mass states and allows a direct measurement of t, the square of the four-momentum …

Charged Particles And Neutral Kaons In Photoproduced Jets At Hera, J. Breitweg, M. Derrick, D. Krakauer, S. Magill, D. Mikunas, B. Musgrave, J. Repond, R. Stanek, R. L. Talaga, R. Yoshida, H.

Charged particles (h±) and K0 mesons have been studied in photoproduced events containing at least one jet of ET > 8 GeV n a pseudorapidity interval (-0.5, 0.5) in the ZEUS laboratory frame. Distributions are presented in terms of transverse momentum, pseudorapidity and distance of the particle from the axis of a jet. The properties of h± within the jet are described well using the standard settings of PYTHIA, but the use of the multiparton interaction option improves the description outside the jets.

The shape of jets produced in quasi-real photon-proton collisions at centre-of-mass energies in the range 134-277 GeV has been measured using the hadronic energy flow. The measurement was done with the ZEUS detector at HERA. Jets are identified using a cone algorithm in the η - φ plane with a cone radius of one unit. Measured jet shapes both in inclusive jet and dijet production with transverse energies EjetT > 14 GeV are presented. The jet shape broadens as the jet pseudorapidity (ηjet) increases and narrows as EjetT increases. In dijet photoproduction, the jet shapes have been measured separately for samples …

Photon diffractive dissociation, γp → Xp, has been studied at HERA with the ZEUS detector using ep interactions where the virtuality Q2 of the exchanged photon is smaller than 0.02 GeV2. The squared four-momentum t exchanged at the proton vertex was determined in the range 0.073 < \t\ < 0.40 GeV2 by measuring the scattered proton in the ZEUS Leading Proton Spectrometer. In the photonproton centre-of-mass energy interval 176 < W < 225 GeV and for masses of the dissociated photon system 4 < Mx < 32 GeV, the t distribution has an exponential shape, dN/d\t\ ∝ exp (-b\t\), with a slope parameter b = 6.8 ± 0.9 (stat.) +1.2-1.1 (syst.) GeV-2.

Elastic And Proton-Dissociative Ρ0 Photoproduction At Hera, J. Breitweg, M. Derrick, D. Krakauer, S. Magill, D. Mikunas, B. Musgrave, J. Repond, R. Stanek, R. L. Talaga, R. Yoshida, H.

Elastic and proton-dissociative ρ0 photoproduction (γp → p0p, γp → ρ0N, respectively, with p0 → π+π-) has been studied in ep interactions at HERA for photon-proton centre-of-mass energies in the range 50 < W < 100 GeV and for |t| < 0.5 GeV2, where t is the square of the four-momentum transfer at the proton vertex; the results on the proton-dissociative reaction are presented for masses of the dissociated proton system in the range M2N < 0.1W2. For the elastic process, the π+π- invariant mass spectrum has been investigated as a function of t. As in fixed target experiments, the ρ0 resonance shape is asymmetric; this asymmetry decreases with increasing |t|, as expected in models in which the asymmetry is ascribed to the interference of resonant and non-resonant π+π- production. The cross section has been studied as a function of W; a fit to the resonant part with the form Wa gives a = 0.16 ± 0.06 (stat.) +0.11-0.15 (syst.). The resonant part of the γp → π+π-p cross section is 11.2 ± 0.1 (stat.) +1.1-1.2 (syst.) μb at 〈W〉 = 71.7 GeV. The t dependence of the cross section can be described by a function of the type Aρ exp (-bρ|t| + cρt2) with bρ = 10.9 ± 0.3 (stat.) +1.0-0.5 (syst.) GeV-2 and cρ = 2.7 ± 0.9 (stat.) +1.9-1.7 (syst.) GeV-4. The t dependence has also been studied as a function of W and a value of the slope of the pomeron trajectory α IP′ = 0.23 ± 0.15 (stat.) +0.10-0.07 (syst.) GeV-2 has been deduced. The ρ0 spin density matrix elements r0400 r041-1 and ℜe[r0410] have been measured and found to be consistent with expectations based on s-channel helicity conservation. For proton-dissociative π+π- photoproduction in the ρ0 mass range, the distributions of the two-pion invariant mass, W and the polar and azimuthal angles of the pions in the helicity frame are the same within errors as those for the elastic process. The t distribution has been fitted to an exponential function with a slope parameter 5.8 ± 0.3 (stat.) ± 0.5 (syst.) GeV-2. The ratio of the elastic to proton-dissociative ρ0 photoproduction cross section is 2.0 ± 0.2 (stat.) ± 0.7 (syst.).

Supernumerary Teeth In Pleistocene, Recent, And Hybrid Individuals Of The Spermophilus Richardsonii Complex (Sciuridae), H. Thomas Goodwin

Faculty Publications

A supernumerary distal upper molar, always expressed bilaterally, occurred in Pleistocene (one of 204) and Recent (five of 1,667) specimens of the Spermophilus richardsonii complex. Among Recent specimens with the abnormality, three of four with known provenance came from adjacent colonies with hybrids of S. richardsonii (Richardson's ground squirrel) and S. elegans (Wyoming ground squirrel). Elsewhere, the trait was rare in S. richardsonii (one of 947) and absent in S. elegans (out of 668). Affected individuals exhibited normal P3-M2, but two aberrant teeth distal to M2. Aberrant teeth exhibited a mosaic of features typical of M2, M3, and atypical of …
