Personality, Affect and EEG: An Integration of Three Models to Predict Neural Patterns of Activity
No full textThis research assessed whether individual differences in frontal and posterior electroencephalogram (EEG) alpha were associated with basic dimensions of personality, extraversion and neuroticism. A theoretical model proposed that extraversion and neuroticism (measured by the NEO-PI-R) were related to the affect circumplex and Heller's (1990, 1993) model of brain activity associated with affect. Other hypothesized dimensions of affect (PANAS-GEN Positive and Negative Affect Scales) were also measured. Resting EEG was recorded for subjects on one occasion for eight 60-second resting baseline periods. Mean log-transformed alpha power was extracted from the EEG for each electrode site, and asymmetry scores were computed across homologous electrode sites by subtracting left from right hemisphere mean log-transformed power. Results indicated that increased relative right posterior activity was associated with higher neuroticism and Negative Affect (NA) scores, and these effects for posterior activity remained unchanged when the effect of current mood was included in the statistical model. Predicted effects for extraversion and neuroticism associated with frontal activity emerged when the effect of current mood was included in the statistical model. Results support the model of brain activity and affect proposed by Heller (1990,1993), as well as the model for brain activity and personality proposed in the current research.Made available in DSpace on 2015-09-25T20:40:01Z (GMT).

The polarization of neutrons from the photodisintegration of deuterium
No full textThe polarization of neutrons photoproduced from deuterium at about 148˚ in the center of mass system was measured at four intervals in the photon energy range of 11.0-22.9 Mev in the laboratory system. The neutron polarization was analyzed in a low pressure helium diffusion cloud chamber by scattering the neutrons and observing the left-right asymmetry in the helium gas nuclear recoils. This was achieved by photographing the individual recoils on film, then making measurements on the stereoscopically projected recoil track images, and finally subjecting the data to a maximum likelihood calculation. The photography of the random scattering events was accomplished by illuminating the chamber with a slide projector light beam and then detecting the light reflected by the vapor condensation on the recoil paths. The polarizations measured in the four photon energy intervals of 11.0-12.9 Mev, 13.0-15.9 Mev, 16.0•-17.9 Mev and 18.0-22.9 Mev are -0.032±0.078, -0.198±0.086, -.25±.120, and -.296±.137, respectively. The polarization is defined to be positive in the direction of k y x kn o ,the directions of the incoming photon and outgoing photoneutron, respectively. The results are substantially in agreement with the polarization calculations by deSwart and Marshak and by Rustgi; Zernik, Breit and Andrews.Submitted by Jooho Lee ([email protected]) on 2010-08-04T21:50:34Z

Studies of a DNA modification methyltransferase from Rhodobacter sphaeroides
No full textThe DNA methyltransferases represent an interesting class of enzymes for the study of protein-DNA interactions due to their high specificity, structural simplicity, and biological importance. RsrI methyltransferase (MRsrI) from Rhodobacter sphaeroides recognizes duplex d(GAATTC) and deposits methyl groups at the N\sp6 position of central adenine. MRsrI was purified to homogeneity from R. sphaeroides, and its gene cloned and sequenced. The purification used four chromatography columns, and yielded up to 100 g of enzyme. MRsrI was overexpressed in E. coli and the yield of the purification improved by about 100-fold with respect to that from R. sphaeroides.Several physical and biochemical properties of the RsrI methyltransferase were determined: molecular weight under denaturing and nondenaturing conditions, isoelectric point, optimal reaction conditions, the mode of methyl group transfer, and the enzyme-DNA binding. MRsrI was compared to a functionally identical enzyme from E. coli, EcoRI methyltransferase (MEcoRI). MRsrI and MEcoRI differ in their physical properties, including a striking lack of similarity in their deduced amino acid sequences. The two methyltransferases might recognize the cognate DNA sequence differently, because they do not bind to DNA with equal efficiencies under the same conditions. However, MRsrI and MEcoRI share identical catalytic properties. Both transfer one methyl group to the recognition sequence per binding event.MRsrI and MEcoRI represent an opportunity to elucidate the mode of action of two structurally different but functionally identical enzymes. It is possible that these enzymes retain functional similarity by having essentially the same three dimensional configuration. Alternatively, they might have dissimilar structures as well as mechanistic differences.Made available in DSpace on 2011-05-07T12:57:04Z (GMT). No. of bitstreams: 2

"To Dream a New World: ""race"", Reality and Surreality in Cesaire, Carpentier and Harris"
No full textThis investigation of Cesaire, Carpentier, and Harris and their influences in the Caribbean establishes a framework for the examination of the specific influences of the surrealist movement on Negritude and magical realism and of the ways that other Caribbean writers have responded to and echoed the contentions of these movements. Focusing on Aime Cesaire, Alejo Carpentier, and Wilson Harris, this study presents, first, a history of Surrealism and its involvement with non-European writers and then an analysis of each of the three Caribbean writers' relation to and transformation of surrealist principles. Compromised by the very circumstances of colonialism, Cesaire's Negritude and its poetic expression structure the "Black" in opposition to the European "norm." Alejo Carpentier's hybrid solution, too, is an ambivalent rejection of Europe. Structuring its imaginative reality after the multiple histories and peoples of America, lo real-maravilloso americano extends Cesaire's definitions beyond the bounds of opposition and exclusion and asserts the immanent marvel of America. Wilson Harris subverts both Cesaire's oppositional construction of identity and Carpentier's valorization of American experience. Informed by a fundamental commitment to the diversity of history, tradition, and experience, Harris's syncretic vision points toward the future of the post-colonial condition of the Caribbean.The surrealist with Cesaire, Carpentier, and Harris is a rapprochement with the limits of cultural encounter, the necessities of identity, and the possibilities of transcendence: how Surrealism approaches Caribbean writing, how Caribbean writers reflect and negotiate that approach. Each component of this meeting across space and time, from nineteenth-century Europe to present-day Guiana, is intimately involved in assessing the potentialities of "race," culture, and difference to confine and negate, to create and liberate. This is the experience of Cesaire, Carpentier, and Harris: to break out of confinement and negation not into another set of negations, but into the liberating presence of the representative voice.Made available in DSpace on 2014-12-17T23:29:25Z (GMT).

Improving Inadmissible Hypothesis Testing Procedures in Exponential Family Statistical Models (Lrt, Pointwise Compactness, One-Sided Alternatives)
No full textThis thesis is devoted to constructing tests of hypotheses that dominate a given test which violates certain conditions such as convexity or monotonicity. Many authors, for example, Birnbaum (1955), Matthes and Truax (1967), Ferguson (1967), Eaton (1970) and Marden (1981), (1982), have worked on this type of testing problem. They found that a necessary condition for a test to be admissible is that its acceptance region should satisfy certain convexity and monotonicity conditions. These results are not constructive, however, to the extent that one does not know what test(s) dominate a given inadmissible one.In this thesis the researcher provides a method of constructing a test which strictly dominates one that violates the convexity or the monotonicity conditions. The construction method exploits the case where the parameter is real valued, in which case Ferguson's (1967) construction in one dimension can be used by conditioning on the sufficient statistics of the nuisance parameters. A sequence of tests can be obtained iteratively, each one strictly dominating the previous test. The convergence of this sequence is investigated. It is shown that the relative convex hulls of the acceptance regions decrease. The researcher can only conjecture that the limiting test is "best" in the sense that it can not be improved any further. The conjecture is solved for the case of a discrete dominating measure.Moreover, the Likelihood Ratio Test (L.R.T.) conjecture, proposed by J. Marden in an NSF proposal (1982), is addressed and partially solved in this thesis. The L.R.T. conjecture states that the more restrictions which are put on the alternative space, the higher the power of the L.R.T.Made available in DSpace on 2014-12-16T18:31:30Z (GMT).

The Effects of an Experimental Curriculum Development Project in Statistics on The Achievement and Attitude of Tenth Grade Students in Liberia
No full textProblem. Mathematics has always been accorded a prominent position in the secondary schools of Liberia. Certain problems, however, tend to hinder the effective teaching and learning of this subject. One of these problems is the availability of appropriate curricular materials and products and the assessment of their efficacy on student outcomes. This research was conducted to address this problem.Purpose of Study. To assess the teachability of statistics in Liberian Schools by investigating the effects of an exprimental project in statistics on the achievement and attitude of tenth graders in Liberia.Procedures. Eight teachers and 339 students of 11 classes in Liberian Schools participated in the study. Students took a statistics achievement test before and after they were taught from curricular materials in statistics and an attitude inventory at the end of the study.Effect sizes and learning indices (loss, retentivity, and gain indices) were computed to assess learning outcomes. Canonical analysis was used to determine the interrelatedness of independent and dependent variables. Regression Analysis was used to predict posttest scores on statistics. Attitudinal items were analyzed by clustering and ranking responses.Findings. (1) Students showed a 2.77 standard deviation unit superiority of performance on posttest than on pretest total scores. (2) Students generally expressed positive attitudes towards teaching and learning statistics. (3) Junior High School Mathematics Average, Years Student Intends to Study Mathematics, and Pretest Scores were found to be predictors of posttest scores in Statistics.Conclusions. (1) Use of the curricular materials which were developed tended to improve students' knowledge of statistics and develop in them positive attitudes towards teaching and learning statistics. (2) Statistics is teachable to tenth graders in Liberia.Made available in DSpace on 2014-12-15T18:49:46Z (GMT). No. of bitstreams: 1
