W.E.B. Du Bois and the Basic American Negro Creed: The AAAE, Censorship, and Repressive Tolerance

The authors examine W.E.B. Du Bois Basic American Negro Creed and argue that its exclusion from the Carnegie Corporation funded Bronze Booklets series represents an example of repressive tolerance by the AAAE

Diffusion of Lifelong Learning Policy. The Case of Recognition, Validation and Accreditation of Learning Outcomes

The purpose of this study is to understand the diffusion and adoption of lifelong learning policy discourses at the global and national levels by examining the policies of recognition of learning outcomes across 35 countries in Europe, employing content analysis and statistical analysis. Findings, conclusions and limitations are discussed

Historical Memory and the Construction of Adult Education Knowledge: The Role of Selectivity in Majoritarian Narratives

Adult education historical narratives tend to reflect a majoritarian view in which the theoretical formulations of African American and other persons of color tend to be minimized or forgotten. Drawing on the concept of counter narrative and Ricoeur’s concept of “happy forgetting”, we argue that selectivity in constructing adult education historical knowledge overlooks scholarship in the past 20 years that highlight the theoretical and programmatic contributions to adult education of African American adult educators. We offer two examples for discussion and propose that challenging majoritarian narratives involves conscious and critical reflection on historical method and the re-telling of counter narratives as a step toward reconstructing adult education historical knowledge

Synoptic Judgment: Constructing Cross Racial Dialogues in a Post Racial Society

Synoptic judgment, understood as the act of seeing diverse perspectives, is presented as pedagogically useful to analyze and interpret racialized narrative in order to reveal and challenge racial injustice. Implications for classroom practice are offered as a means to assist adult educators and learners to meaningfully learn across racial boundaries while acknowledging the way in which power and privilege shape epistemology

Who Can Speak for Whom? Using Counter-Storytelling to Challenge Racial Hegemony

Dialogues of socially significant forms of human difference such as race are constrained by hegemony. Critical Race Theory’s counter-storytelling is explored as a means of challenging the majoritarian stories that reinforce racial hegemony in the dominant discourse

Like Peeling an Onion: An Examination of Cultural Identity Among Adult Learners

This paper describes the results of a study concerning the cultural identity of adult learners in graduate programs at the University of Georgia. Employing analytic induction research design the research team, itself a culturally diverse group of graduate students and professors, analyzes focus group transcript data. The conclusion is reached that verbal statements aside, cultural identity is complex and manifested situationally. Adult educators are advised to adopt sophisticated tools to assess learner identity issues in order to challenge learners to think more critically about their assumptions and biases toward those who are culturally different

LISA, binary stars, and the mass of the graviton

We extend and improve earlier estimates of the ability of the proposed LISA (Laser Interferometer Space Antenna) gravitational wave detector to place upper bounds on the graviton mass, m_g, by comparing the arrival times of gravitational and electromagnetic signals from binary star systems. We show that the best possible limit on m_g obtainable this way is ~ 50 times better than the current limit set by Solar System measurements. Among currently known, well-understood binaries, 4U1820-30 is the best for this purpose; LISA observations of 4U1820-30 should yield a limit ~ 3-4 times better than the present Solar System bound. AM CVn-type binaries offer the prospect of improving the limit by a factor of 10, if such systems can be better understood by the time of the LISA mission. We briefly discuss the likelihood that radio and optical searches during the next decade will yield binaries that more closely approach the best possible case.Comment: ReVTeX 4, 6 pages, 1 figure, submitted to Phys Rev

The conservation of energy-momentum and the mass for the graviton

In this work we give special attention to the bimetric theory of gravitation with massive gravitons proposed by Visser in 1998. In his theory, a prior background metric is necessary to take in account the massive term. Although in the great part of the astrophysical studies the Minkowski metric is the best choice to the background metric, it is not possible to consider this metric in cosmology. In order to keep the Minkowski metric as background in this case, we suggest an interpretation of the energy-momentum conservation in Visser's theory, which is in accordance with the equivalence principle and recovers naturally the special relativity in the absence of gravitational sources. Although we do not present a general proof of our hypothesis we show its validity in the simple case of a plane and dust-dominated universe, in which the `massive term' appears like an extra contribution for the energy density.Comment: 9 pages, accepted for publishing in GR

Using binary stars to bound the mass of the graviton

Interacting white dwarf binary star systems, including helium cataclysmic variable (HeCV) systems, are expected to be strong sources of gravitational radiation, and should be detectable by proposed space-based laser interferometer gravitational wave observatories such as LISA. Several HeCV star systems are presently known and can be studied optically, which will allow electromagnetic and gravitational wave observations to be correlated. Comparisons of the phases of a gravitational wave signal and the orbital light curve from an interacting binary white dwarf star system can be used to bound the mass of the graviton. Observations of typical HeCV systems by LISA could potentially yield an upper bound on the inverse mass of the graviton as strong as $h/m_{g} = \lambda_{g} > 1 \times 10^{15}$ km ($m_{g} < 1 \times 10^{-24}$ eV), more than two orders of magnitude better than present solar system derived bounds.Comment: 21 pages plus 4 figures; ReVTe

The Role of Media and Popular Culture in the Mis/Education of Adults

The purpose of this symposium is to explore multiple perspectives on the role of media in the education and mis-education of adults, and to consider how educators might draw on media in developing a critical public pedagogy
