Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

High-resolution mapping reveals hundreds of genetic incompatibilities in hybridizing fish species
No full textHybridization is increasingly being recognized as a common process in both animal and plant species. Negative epistatic interactions between genes from different parental genomes decrease the fitness of hybrids and can limit gene flow between species. However, little is known about the number and genome-wide distribution of genetic incompatibilities separating species. To detect interacting genes, we perform a high-resolution genome scan for linkage disequilibrium between unlinked genomic regions in naturally occurring hybrid populations of swordtail fish. We estimate that hundreds of pairs of genomic regions contribute to reproductive isolation between these species, despite them being recently diverged. Many of these incompatibilities are likely the result of natural or sexual selection on hybrids, since intrinsic isolation is known to be weak. Patterns of genomic divergence at these regions imply that genetic incompatibilities play a significant role in limiting gene flow even in young species. © Schumer et al
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied

COMBINING PHYSICAL AND MENTAL PRACTICES OF A DART-THROWING TASK ENHANCES MOTOR LEARNING
No full textMackenzie Manning, Hannah Walker, Joy Carlson, Hannah Dresner, Marcos Daou. Coastal Carolina University, Conway, SC.
BACKGROUND: Determining practical ways to improve motor skill learning and approaches to perform under-pressure are crucial to enhance adaptive behavior. Utilizing visualization technique while practicing a skill may yield benefits to skill acquisition. To address this question, the present study aimed to investigate whether the combination of physical and mental practice (visualization) of a dart-throwing task would enhance motor learning. METHODS: Thirty participants were divided in 2 groups (15 visualization/dart group; and 15 only dart group) and required to perform 3 dart-throwing phases (pretest: 10 trials; Practice: 6 blocks x 10 trials; 3 immediate Posttests [20 minutes after practice] in random order: Retention: 10 trials - Transfer: 10 trials - High-pressure: 10 trials). Importantly, visualization group “visualized” the skill during the 1-min breaks between practice blocks, while the Dart only group read a nutrition paper during breaks to prevent visualization. Participants threw darts to a target positioned 1.73 m off the ground; and 2.37 m from the throwing line for pretest; practice, retention and high-pressure posttests; while a transfer test was performed from a 3.37 m line. Before practice phase, participants received instructions about dart-throwing skills. Between the practice and posttests phases, participants filled out questionnaires related to Psychological Skills (such as, motivation, competence, anxiety). RESULTS: To assess motor learning, a 2 (Group) by 3 (Posttest) mixed-factor ANCOVAs (with repeated measures on the second factor) were conducted for radial error (accuracy) and bivariate variable error (precision), with pretest radial error and bivariate variable error serving as the respective covariate. On these preliminary results (30 participants data collected out of 56 expected) there was a main effect of group p = 0.041; a main effect of posttest p = 0.023; but no group by posttest interaction p = 0.251. Mean posttests scores showed superior performance for the visualization group [depicted in bold] (lower scores representing better learning): retention test (10.82 cm ± 3.44 cm vs 8.43 cm ± 2.39 cm); transfer test (18.32 cm ± 5.41 vs 14.35 cm ± 4.12 cm); high-pressure test (11.49 cm ± 4.2 cm vs 7.85 cm ± 2.5 cm). CONCLUSION: The combination of visualization and dart practice enhanced motor learning by showing less errors - superior accuracy results in all posttests)
Intern experience at CH���M Hill, Inc.: an internship report
No full textIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
Transition to turbulence in a qblique shock-wave/boundary-layer interaction at M=15
No full textDirect numerical simulations are carried out for different forcing techniques to trigger transition during the interaction between an oblique shock-wave and a laminar boundary-layer at M = 1.5. Three forcing methods are used: a) forcing of oblique unstable modes, whose shape and behaviour are determined by the local linear stability theory, b) broadband free-stream acoustic disturbances, and c) a cold plasma flow control device. While the oblique-mode breakdown is dominant for low-amplitude forcing, long streaky structures drive the transition process in a high-amplitude disturbance environment. LES are also performed on the experimental setup by the Institute of Theoretical and Applied Mechanics (ITAM) from Novosibirsk State University with cold plasma actuation. As well as the disturbance type, the effect of Reynolds number and forcing amplitude will be investigated
