Eliminating Aggregation Bias in Experimental Research: Random Coefficient Analysis as an Alternative to Performing a by-subjects and/or by-items ANOVA
Glenn L. Thompson
Tutorials in Quantitative Methods for Psychology , 2008,
Abstract: Experimental psychologists routinely simplify the structure of their data by computing means for each experimental condition so that the basic assumptions of regression/ANOVA are satisfied. Typically, these means represent the performance (e.g. reaction time or RT) of a participant over several items that share some target characteristic (e.g. Mean RT for high-frequency words). Regrettably, analyses based on such aggregated data are biased toward rejection of the null hypothesis, inflating Type-I error beyond the nominal level. A preferable strategy for analyzing such data is random coefficient analysis (RCA), which can be performed using a simple method proposed by Lorch and Myers (1990). An easy to use SPSS implementation of this method is presented using a concrete example. In addition, a technique for evaluating the magnitude of potential aggregation bias in a dataset is demonstrated. Finally, suggestions are offered concerning the reporting of RCA results in empirical articles.
Remembering “The Contract”: Recollections of Bahamians
Thompson, Tracey L.
International Journal of Bahamian Studies , 2012,
Abstract: Between 1943 and 1965 an estimated 30,000 Bahamian men and women migrated temporarily to the United States on short-term contracts to work in the agricultural sector. The programme, known as the British West Indies Labor Program, was created to fill labour shortages caused when Americans left the farms to work in more profitable war industries or to serve in the armed forces during World War II. In the Bahamas the programme was sometimes referred to as “The Contract” because each worker signed a contractual agreement to work in the United States. Drawing upon oral histories collected in the early 1990s, this paper uses the recollections of former Contract workers to explore the personal, economic and social ramifications of their experiences working on the Contract.

HST/WFPC2 Morphologies of K-selected Extremely Red Galaxies
L. Yan,D. Thompson
Physics , 2002, DOI: 10.1086/367686
Abstract: We selected 115 extremely red objects (EROs) from deep HST WFPC2 archive data combined with ground-based K-band images, with (F814W - Ks) >= 4mag, K-band SNR >= 5, and a median limiting Ks magnitude of 18.7mag, over a corresponding area of 228 sq. arcminutes, for a morphological study of the ERO galaxy population. The survey covered a total of 409 sq. arcminutes over 77 separate WFPC2 fields. This is the first complete sample of bright EROs with high resolution HST morphologies. From a visual morphological classification, we find that 30+/-5% of our EROs have morphologies consistent with a pure bulge or bulge-dominated galaxy (equivalent to E/S0), while disks comprise 64+/-$7% of the sample. Only 6% of the EROs remained unclassifiable. Mergers or strongly interacting systems, which includes sources from both classes, make up 17+/-4% of the full sample. The quantitative MDS profile fitting is consistent with these results. These results highlight the complex nature of optical/near-IR color selected EROs. The dominant component of our sample is comprised of disks, not spheroids or strongly interacting systems like HR10. Using Bruzual & Charlot SED models, we investigated population differences in EROs selected by their (I-K) vs. (R-K) colors and found that I-band based surveys preferentially select systems with prolonged star formation. Real differences in the surface densities of EROs in R-band and I-band based surveys may reflect this color selection effect, complicating the comparisons between and interpretations on the nature of the ERO population.

Outstanding problems in local helioseismology
L. Gizon,M. J. Thompson
Physics , 2010, DOI: 10.1002/asna.200610720
Abstract: Time-distance helioseismology and related techniques show great promise for probing the structure and dynamics of the subphotospheric layers of the Sun. Indeed time-distance helioseismology has already been applied to make inferences about structures and flows under sunspots and active regions, to map long-lived convective flow patterns, and so on. Yet certainly there are still many inadequacies in the current approaches and, as the data get better and the questions we seek to address get more subtle, methods that were previously regarded as adequate are no longer acceptable. Here we give a short and partial description of outstanding problems in local helioseismology, using time-distance helioseismology as a guiding example.
On the generic curve of genus 3
T. Shaska,J. L. Thompson
Mathematics , 2012,
Abstract: We study genus $g$ coverings of full moduli dimension of degree $d=[\frac {g+3} 2]$. There is a homomorphism between the corresponding Hurwitz space $\H$ of such covers to the moduli space $\M_g$ of genus $g$ curves. In the case $g=3$, using the signature of such covering we provide an equation for the generic ternary quartic. Further, we discuss the degenerate subloci of the corresponding Hurwitz space of such covers from the computational group theory viewpoint. In the last section, we show that one of these degenerate loci corresponds to the locus of curves with automorphism group $C_3$. We give necessary conditions in terms of covariants of ternary quartics for a genus 3 curve to belong to this locus.
Field dependent anisotropy change in a supramolecular Mn(II)-[3x3] grid
Oliver Waldmann,L. Zhao,L. K. Thompson
Physics , 2002, DOI: 10.1103/PhysRevLett.88.066401
Abstract: The magnetic anisotropy of a novel Mn(II)-[3x3] grid complex was investigated by means of high-field torque magnetometry. Torque vs. field curves at low temperatures demonstrate a ground state with S > 0 and exhibit a torque step due to a field induced level-crossing at B* \approx 7.5 T, accompanied by an abrupt change of magnetic anisotropy from easy-axis to hard-axis type. These observations are discussed in terms of a spin Hamiltonian formalism.
