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
Effects of external disturbances on turbulent boundary layers
No full textThe state of a turbulent boundary layer developing under the influence of different types of freestream turbulence (FST) is examined. Different FST conditions with different length scales and turbulence intensity levels are generated using an active grid. Experiments are performed using two different techniques allowing simultaneous measurements of the freestream and the boundary layer: single component hot-wire anemometry and multi-camera planar Particle Image Velocimetry (PIV). Penetration level of the freestream into the boundary layer and the effect on the near wall region are shown to depend on the turbulence characteristics of the freestream. These interactions will further be investigated using spectral analysis from hot-wire measurements and also coherent structures associated with these interactions will be studied using PIV data

Dataset for paper titled Robust features of a turbulent boundary layer subjected to high-intensity free-stream turbulence
No full textThis dataset contains a matlab file required to reproduce all the figures in the above mentioned paper. If you use any of the data from this dataset, please cite the following article,

Here is further information on the dataset:
The variables contained in the file are:
B = log-law fitting parameter described in equation (1.1)
kappa = log-law fitting parameter described in equation (1.1)
delta = boundary layer thickness (units: meters)
lamb_inf = Taylor microscale in the free-stream (units: meters)
Lu_inf = integral lengthscale in the free-stream (units: meters)
nu = kinematic viscosity (units: m^2/s)
Re_lamb_inf = Taylor microscale based Reynolds number in the free-stream
Re_tau = friction velocity based Reynolds number
Re_theta = momentum thickness based Reynolds number
u2_inf = streamwise velocity variance in the free-stream
(units: m^2/s^2)
U_inf = streamwise mean velocity in the free-stream (units: m/s)
U_tau = mean friction velocity (units: m/s)
uU_inf = free-stream turbulence intensity
Fu = streamwise velocity flatness profiles
Su = streamwise velocity skewness profiles
U = streamwise mean velocity profiles (units: m/s)
u2 = streamwise velocity variance profiles (units: m^2/s^2)
y = wall-normal position for profiles (units: meters)
E11_inf = free-stream spectra
kE11 = pre-multiplied spectra at all wall-normal positions for each case
(units of m^2/s^2)
Gg = global gain function
kpu = wall-unit normalised wavenumber for all spectra

zetap_Coh_G = wall-unit normalised wavelength for spectral coherence case G
zetap_Coh_H = wall-unit normalised wavelength for spectral coherence case H
zetap_Coh_N = wall-unit normalised wavelength for spectral coherence case N
For all variables except for the coherence plots, the data is stored as
"cell" elements in MATLAB where the first element of the cell (index = 1)
is case A, the second element of the cell (index = 2) is case B, and so on.

Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe
