Seal Molt Model
No full text<p>Programs for fitting progress of molt in elephant seals, written in C++. THe program should work on a Linux system as is, using the data included, but knowledge of C++ and Bayesian statistics are necessary to understand the output or adapt the code. The program fits a logistic curve to observations that increase from 0 to 100% molt for multiple individuals across multiple years. Individual logistic parameters are fitted to a hyperdistribution across years and animals. </p>
<p>Files with extension .h or .cpp contain the code:<br>1) modelMolt.h defines the molt class and runs all calculations, and includes subroutines in header files<br>2) utilities.cpp has commonly used subroutines<br>3) util.h has commonly used subroutines<br>4) Array2D.h is used within subroutines<br>5) likelihood.h has common likelihood functions for statistical calculations<br>6) statistics.h has common statistical functions<br>7) randomgenerator.h has a random number generator<br>8) modelMolt.cpp has the main function, accepting command-line parameters and executing a complete run</p>
<p><br>The file FemaleMolt.csv has sample data.

<p><br>To illustrate compilation, assume file #8 and the data file are in a folder FOLDERNAME. The following creates an executable program in FOLDERNAME:<br>> cd FOLDERNAME<br>> g++ -Wall modelMolt.cpp -o modelMolt.exe</p>
<p>Before compiling, edit lines 103-104 in modelMolt.h. They identify the folder to which results will be written. Those should be renamed as needed, and both folders must be created before executing. Then, to execute a run for 4000 steps, showing results every 500 steps, with output files named OUTPUT within those folders:<br>> ./modelMolt.exe FOLDERNAME FemaleMolt 4000 500 1 OUTPUT</p>
<p>There is one output file showing all parameter estimates of the Gibbs chain for every individual animal within the folder named 'pathFemale' (line 104). There are files of parameters for each year and grand hyperparameters within the folder named 'path' (line 103). Each file has 4000 rows for the 4000 steps chosen at run time.</p>

Marker rescue mapping of the combined Condit/Dales collection of temperature-sensitive vaccinia virus mutants
No full textAbstractComplementation analysis of the combined Condit/Dales collection of vaccinia virus temperature-sensitive mutants has been reported (Lackner, C.A., D'Costa, S.M., Buck, C., Condit, R.C., 2003. Complementation analysis of the Dales collection of vaccinia virus temperature-sensitive mutants. Virology 305, 240–259), however not all complementation groups have previously been assigned to single genes on the viral genome. We have used marker rescue to map at least one representative of each complementation group to a unique viral gene. The final combined collection contains 124 temperature-sensitive mutants affecting 38 viral genes, plus five double mutants
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
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
Bipolar disorder, Type A behavior, and coronary disease
No full textThis paper describes a model for integrating two psychological constructs--bipolar disorder and the Type A behavior pattern--each of which has been associated with enhanced risk of coronary heart disease (CHD). It highlights similarities between manic/hypomanic behaviors associated with bipolarity and the behaviors observed in Type A individuals. The proposed model conceptualizes Type A behavior as an alternating pattern of coping with challenging and stressful events. Thus, initial coping efforts are manifested as behavioral hyper-reactivity (including mania/hypomania), but this gives way to hypo-reactivity (including helplessness and depression) after repeated failure to assert control and/or attain relevant goals. This alternation of Type A coping patterns resembles the affective and behavioral transitions often seen in bipolar patients. Future research on psychological, epidemiological, and pathophysiological issues concerning CHD should document areas of commonality and independence between bipolarity and Type A behavior. Such studies would benefit from consideration of a model that identifies psychosocial dimensions common to Type A, mania/hypomania, and depression.Peer reviewedThis is an electronic version of an article published in Glass, David C. and Richard J.
