    Minority Student Perceptions of Professional Pscyhology Application Packets: A Qualitative Study

    This article reports the results of a qualitative study designed to determine issues salient in Black and Hispanic American students\u27 review and evaluation of program-application packets in professional psychology. The study served as an extension to the Yoshida et al. (1989) quantitative investigation. Students interested in pursuing doctoral studies in counseling or school psychology (N = 22) served as the sample. The qualitative methodology incorporated a think-aloud procedure and semistructured interviews. A theme analysis of transcribed interviews identified both major and minor themes central to participants\u27 evaluation of the packets. Major themes included financial aid, program requirements and course descriptions, demography of the student body, and the quality and clarity of application material. Specific suggestions on developing an application packet to send to inquiring prospective students are put forth. It is recommended that such a packet could serve as a costeffective minority-recruitment strategy

    Improved memory loading techniques for the TSRV display system

    A recent upgrade of the TSRV research flight system at NASA Langley Research Center retained the original monochrome display system. However, the display memory loading equipment was replaced requiring design and development of new methods of performing this task. This paper describes the new techniques developed to load memory in the display system. An outdated paper tape method for loading the BOOTSTRAP control program was replaced by EPROM storage of the characters contained on the tape. Rather than move a tape past an optical reader, a counter was implemented which steps sequentially through EPROM addresses and presents the same data to the loader circuitry. A cumbersome cassette tape method for loading the applications software was replaced with a floppy disk method using a microprocessor terminal installed as part of the upgrade. The cassette memory image was transferred to disk and a specific software loader was written for the terminal which duplicates the function of the cassette loader

    Longitudinal Polarization at future e+e−e^+e^- Colliders and Virtual New Physics Effects

    Get PDF
    The theoretical merits of longitudinal polarization asymmetries of electron-positron annihilation into two final fermions at future colliders are examined, using a recently proposed theoretical description. A number of interesting features, valid for searches of virtual effects of new physics, is underlined, that is reminiscent of analogous properties valid on top of ZZ resonance. As an application to a concrete example, we consider the case of a model with triple anomalous gauge couplings and show that the additional information provided by these asymmetries would lead to a drastic reduction of the allowed domain of the relevant parameters.Comment: 18 pages and 1 figure. e-mail: [email protected]

    Spin Dynamics of the Magnetoresistive Pyrochlore Tl_2Mn_2O_7

    Full text link
    Neutron scattering has been used to study the magnetic order and spin dynamics of the colossal magnetoresistive pyrochlore Tl_2Mn_2O_7. On cooling from the paramagnetic state, magnetic correlations develop and appear to diverge at T_C (123 K). In the ferromagnetic phase well defined spin waves are observed, with a gapless (Δ<0.04\Delta <0.04 meV) dispersion relation E=Dq^{2} as expected for an ideal isotropic ferromagnet. As T approaches T_C from low T, the spin waves renormalize, but no significant central diffusive component to the fluctuation spectrum is observed in stark contrast to the La1−x_{1-x}(Ca,Ba,Sr)x_xMnO3_3 system. These results argue strongly that the mechanism responsible for the magnetoresistive effect has a different origin in these two classes of materials.Comment: 4 pages (RevTex), 4 figures (encapsulated postscript), to be published in Phys.

    Solanum phylogeny inferred from chloroplast DNA sequence data

    Get PDF
    Journal ArticleA data set derived from gene sequences of ndhF is used to deduce phylogenetic relationships among the subgenera of Solanum, among related genera of the tribe Solaneae, and within selected Solanum clades. Complete ndhF sequences were obtained for 12 species o f Solanum, representing five of the seven subgenera. ndhF sequences also were obtained from species of Capsicum, Cyphomandra, Datura, jaltomata, Lycopersicon, Nicotiana, and Physalis. Results of a parsimony analysis of these data indicate that the Solanum species form a monophyletic clade with Capsicum rather weakly supported as the sister group

    Work group inclusion : test of a scale and model

    Get PDF
    We develop a theoretically based 10-item measure of work group inclusion comprised of two components (belongingness and uniqueness) and use this measure to empirically test the nomological network of work group inclusion developed by Shore et al. In Phase 1, we use two samples of full-time employees to develop and refine items as well as establish content validity. In Phase 2, we demonstrate convergent, discriminant, and incremental validity with both conceptually related and unrelated constructs. In Phase 3, we use data from an additional sample of employees and supervisors to test criterion-related validity and mediation by examining the multilevel relationships between inclusion and important antecedents and outcomes. Across the three phases of our study, the results demonstrate support not only for the factor structure, reliability, and validity of our work group inclusion measure but also for a theoretical model in which the construct of inclusion has important implications for individuals and organizations

    The Persistence Of Traditional Gender Stereotypes: Evidence From The Distribution Of Academic Honors At A Female-Majority University

    Get PDF
    A shift from male-majority to female-majority university campuses has opened up new areas for research on gender bias, stereotypes, and discrimination. At one large state university on the west coast, there were more female than male graduates in Spring, 2008 in 7 out of 8 colleges, including the traditionally male-majority areas of business and science.&nbsp; Relative probabilities for men and women of receiving honors in each major field of study at this school, compared to national data of gender breakdowns by field in 1980, showed that men and women were still relatively more likely to receive honors in fields that were traditionally male and female, respectively. Findings also cast doubt upon Kanter&rsquo;s tokenism hypothesis. Curiously, it was traditionally female, not male, fields that had the highest levels of gender inequity, though gender inequity overall may be on a decline. More research is needed to identify why this difference between gender and honors still exists. Universities should also be aware of the continuing potential for subtle gender discrimination, even in fields where equal numbers of men and women participate
