Family Breast Cancer Education: A Model for African American Women

The purpose of this study, funded by the American Cancer Society, was to increase knowledge and understanding, i.e., the willingness and ability to discuss, of breast cancer in southern minority women and their families. A family model of health education guided the research questions. (a) To what extent will an action research intervention increase knowledge about the causes and treatment of breast cancer in minority women? (b) To what extent will an action research intervention increase willingness to talk with family members? The t-test analysis of a 67-item, self- administered survey indicated significant increases in knowledge of cancer and in their willingness to talk with family members about breast cancer. In addition, they reported increases in comfort level about discussing breast cancer as well as willingness to talk with others about their own (possible) positive diagnosis. We infer that increased comfort level and willingness to talk with others has a relationship to increased awareness of breast cancer

Hyperfine-Structure-Induced Depolarization of Impulsively Aligned I2\rm I_2 Molecules

A moderately intense $450$ fs laser pulse is used to create rotational wave packets in gas phase $\rm{I_2}$ molecules. The ensuing time-dependent alignment, measured by Coulomb explosion imaging with a delayed probe pulse, exhibits the characteristic revival structures expected for rotational wave packets but also a complex non-periodic substructure and decreasing mean alignment not observed before. A quantum mechanical model attributes the phenomena to coupling between the rotational angular momenta and the nuclear spins through the electric quadrupole interaction. The calculated alignment trace agrees very well with the experimental results.Comment: 6 pages, 4 figures, and Supplementary Information.

Transformative sensemaking: Development in Whose Image? Keyan Tomaselli and the semiotics of visual representation

The defining and distinguishing feature of homo sapiens is its ability to make sense of the world, i.e. to use its intellect to understand and change both itself and the world of which it is an integral part. It is against this backdrop that this essay reviews Tomaselli's 1996 text, Appropriating Images: The Semiotics of Visual Representation/ by summarizing his key perspectives, clarifying his major operational concepts and citing particular portions from his work in support of specific perspectives on sense-making. Subsequently, this essay employs his techniques of sense-making to interrogate the notion of "development". This exercise examines and confirms two interrelated hypotheses: first, a semiotic analysis of the privileged notion of "development" demonstrates its metaphysical/ ideological, and thus limiting, nature especially vis-a-vis the marginalized, excluded, and the collective other, the so-called Developing Countries. Second, the interrogative nature of semiotics allows for an alternative reading and application of human potential or skills in the quest of a more humane social and global order, highlighting thereby the transformative implications of a reflexive epistemology.Web of Scienc
