Oscillating Boundaries Between Binaries: Narrative Tools for Understanding Judges 4 & 19

This paper will show that dichotomies in Judges are used as narrative tools to express anxiety about the ever-changing world of Ancient Israel. In the Deborah narrative of Judges 4, the binaries of masculine/feminine and male/female criss-cross, and in the concubine\u27s narrative, the binaries of out/in and public/domestic become confused as the narrative—along with the events themselves—crumble out of control and lead to civil war, rape, and pandemonium on a grand scale. The narrators of Judges oscillate between these binaries in order to convey the sense of moral upheaval and social confusion wrought from the changing political landscape of Ancient Israel. A deeper understanding of the text is gained from this reading, such that the commonly-made presumption that these tales are simply reflections of a misogynist society is replaced with a proto-feminist reading; rather, these stories display the danger of a world where too much unchecked power is left in the wrong hands. The finite message of these stories is this: a civilized society needs a centralized government, or the types of heinous acts described in the book of Judges will never end

Leveraging Epidemiology to Improve Risk Assessment.

The field of environmental public health is at an important crossroad. Our current biomonitoring efforts document widespread exposure to a host of chemicals for which toxicity information is lacking. At the same time, advances in the fields of genomics, proteomics, metabolomics, genetics and epigenetics are yielding volumes of data at a rapid pace. Our ability to detect chemicals in biological and environmental media has far outpaced our ability to interpret their health relevance, and as a result, the environmental risk paradigm, in its current state, is antiquated and ill-equipped to make the best use of these new data. In light of new scientific developments and the pressing need to characterize the public health burdens of chemicals, it is imperative to reinvigorate the use of environmental epidemiology in chemical risk assessment. Two case studies of chemical assessments from the Environmental Protection Agency Integrated Risk Information System database are presented to illustrate opportunities where epidemiologic data could have been used in place of experimental animal data in dose-response assessment, or where different approaches, techniques, or studies could have been employed to better utilize existing epidemiologic evidence. Based on the case studies and what can be learned from recent scientific advances and improved approaches to utilizing human data for dose-response estimation, recommendations are provided for the disciplines of epidemiology and risk assessment for enhancing the role of epidemiologic data in hazard identification and dose-response assessment

Open courseware and shared knowledge in higher education

Journal ArticleMost college and university campuses in the United States and much of the developed world today maintain one, two, or several learning management systems (LMSs), which are courseware products that provide students and faculty with Web-based tools to manage course-related applications. Since the mid-1990s, two predominant models of Web courseware management systems have emerged: commercial and noncommercial. Some of the commercial products available today were created in academia as noncommercial but have since become commercially encumbered. Other products remain noncommercial but are struggling to survive in a world of fierce commercial competition. This article argues for an ethics of pedagogy in higher education that would be based on the guiding assumptions of the nonproprietary, peer-to-peer, open-source software movement

First Evidence of a Precessing Jet Excavating a Protostellar Envelope

We present new, sensitive, near-infrared images of the Class I protostar, Elias 29, in the Ophiuchus cloud core. To explore the relationship between the infall envelope and the outflow, narrowband H2 1-0 S(1), Br-gamma, and narrowband K-continuum filters were used to image the source with the Wide-Field Infrared Camera on the Hale 5m telescope and with Persson's Auxiliary Nasmyth Infrared Camera on the Baade 6.5 m telescope. The source appears as a bipolar, scattered light nebula, with a wide opening angle in all filters, as is typical for late-stage protostars. However, the pure H2 emission-line images point to the presence of a heretofore undetected precessing jet. It is argued that high-velocity, narrow, precessing jets provide the mechanism for creating the observed wide-angled outflow cavity in this source.Comment: 11 pages, 1 figure, 1 tabl

Extracellular Phosphodiesterase from the Growth Medium of the Myxomycete Physarum flavicomum

The plasmodium of the myxomycete Physarum flavicomum secretes cyclic AMP phosphodiesterase into the medium. The extracellular enzyme had a pH optimum between 7 and 8 and a Km of about 500 μM cyclic AMP and was inhibited by theophylline, caffeine and 3-isobutyl-l-methyxanthine (MIX). A marked decrease of enzyme activity was noted in the presence of EDTA, suggesting the requirement of Mg+ + by the enzyme. Addition of Mg+ + and Ca + + stimulated the enzyme while Zn+ + , Co+ + , Pb+ + , Mn+ + , Fe + + + , Ni+ + , and Cu + + all inhibited phosphodiesterase activity. An interesting feature of this extracellular phosphodiesterase was its ability to retain full catalytic activity after prolonged exposure to elevated temperature
