Ordinary Community: Missional Communities as a Helpful Ecclesial Response to the Problem of Postmodernism and Consumerism for the American Evangelical Church

There is a storm approaching the shores of the American evangelical church that is two-fold. First, there is a macro shift in cultural worldview from modernity, which was embedded in the tenets of the Enlightenment project to a new era called postmodernity. Postmodernity is characterized as a harsh reaction against the utopian ideals of the modern world. What is the appropriate ecclesial response of the American evangelical church to the postmodern world? Secondly, the dominant cultural challenge to Christianity in America is the organizing of life around the attachments of a consumer lifestyle. Consumerism dominates American life however it is not a satisfying pursuit. In the face of the false idol of the consumer lifestyle, how can the American evangelical church be an antidote to the problem of consumerism? I claim that missional communities are a helpful ecclesial response to the problem of postmodernism and consumerism in America because they are communal, simple, and sent-out intentional communities of faith offering an alternative narrative of hope. Chapter 1 provides a description of the problem facing the contemporary American evangelical church. Chapter 2 describes the massive cultural worldview shift from modernity to postmodernity and seeks to locate both challenge and opportunity within that shift. Chapter 3 reports on the mythology of the American dream and the trappings of consumerist lifestyles. Chapter 4 surveys the primitive church for helpful contributions of how to express life as a community of faith. Chapter 5 surveys Christian history for contributions from spiritual ancestors to inform missional communities today. Chapter 6 reports on the unique leadership challenges of todays sent out communities through the example of Pauline communities. Chapter 7 concludes the research study with the beliefs and practices necessary for missional communities today to offer an alternative narrative of hope

RETROCAM: A Versatile Optical Imager for Synoptic Studies

We present RETROCAM, an auxiliary CCD camera that can be rapidly inserted into the optical beam of the MDM 2.4m telescope. The speed and ease of reconfiguring the telescope to use the imager and a straightforward user interface permit the camera to be used during the course of other observing programs. This in turn encourages RETROCAM's use for a variety of monitoring projects.Comment: 6 pages, 6 figures, Accepted by A

Automated detection of galaxy-scale gravitational lenses in high resolution imaging data

Lens modeling is the key to successful and meaningful automated strong galaxy-scale gravitational lens detection. We have implemented a lens-modeling "robot" that treats every bright red galaxy (BRG) in a large imaging survey as a potential gravitational lens system. Using a simple model optimized for "typical" galaxy-scale lenses, we generate four assessments of model quality that are used in an automated classification. The robot infers the lens classification parameter H that a human would have assigned; the inference is performed using a probability distribution generated from a human-classified training set, including realistic simulated lenses and known false positives drawn from the HST/EGS survey. We compute the expected purity, completeness and rejection rate, and find that these can be optimized for a particular application by changing the prior probability distribution for H, equivalent to defining the robot's "character." Adopting a realistic prior based on the known abundance of lenses, we find that a lens sample may be generated that is ~100% pure, but only ~20% complete. This shortfall is due primarily to the over-simplicity of the lens model. With a more optimistic robot, ~90% completeness can be achieved while rejecting ~90% of the candidate objects. The remaining candidates must be classified by human inspectors. We are able to classify lens candidates by eye at a rate of a few seconds per system, suggesting that a future 1000 square degree imaging survey containing 10^7 BRGs, and some 10^4 lenses, could be successfully, and reproducibly, searched in a modest amount of time.

uPAR promotes formation of the p130Cas–Crk complex to activate Rac through DOCK180

The urokinase-type plasminogen activator receptor (uPAR) drives tumor cell membrane protrusion and motility through activation of Rac; however, the pathway leading from uPAR to Rac activation has not been described. In this study we identify DOCK180 as the guanine nucleotide exchange factor acting downstream of uPAR. We show that uPAR cooperates with integrin complexes containing β3 integrin to drive formation of the p130Cas–CrkII signaling complex and activation of Rac, resulting in a Rac-driven elongated-mesenchymal morphology, cell motility, and invasion. Our findings identify a signaling pathway underlying the morphological changes and increased cell motility associated with uPAR expression

Draft Genome Sequence of Rhodococcus sp. Strain ATCC 49988, a Quinoline-Degrading Bacterium.

We report here the 4.9-Mb genome sequence of a quinoline-degrading bacterium, Rhodococcus sp. strain ATCC 49988. The draft genome data will enable the identification of genes and future genetic modification to enhance traits relevant to heteroaromatic compound degradation

Influence of Acidic pH on Hydrogen and Acetate Production by an Electrosynthetic Microbiome

Production of hydrogen and organic compounds by an electrosynthetic microbiome using electrodes and carbon dioxide as sole electron donor and carbon source, respectively, was examined after exposure to acidic pH (∼5). Hydrogen production by biocathodes poised at −600 mV vs. SHE increased>100-fold and acetate production ceased at acidic pH, but ∼5–15 mM (catholyte volume)/day acetate and>1,000 mM/day hydrogen were attained at pH ∼6.5 following repeated exposure to acidic pH. Cyclic voltammetry revealed a 250 mV decrease in hydrogen overpotential and a maximum current density of 12.2 mA/cm2 at −765 mV (0.065 mA/cm2 sterile control at −800 mV) by the Acetobacterium-dominated community. Supplying −800 mV to the microbiome after repeated exposure to acidic pH resulted in up to 2.6 kg/m3/day hydrogen (≈2.6 gallons gasoline equivalent), 0.7 kg/m3/day formate, and 3.1 kg/m3/day acetate ( = 4.7 kg CO2 captured).</p

Dystonia Associated with Idiopathic Slow Orthostatic Tremor

Background: We aimed to characterize the clinical and electrophysiological features of patients with slow orthostatic tremor. Case Report: The clinical and neurophysiological data of patients referred for lower limb tremor on standing were reviewed. Patients with symptomatic or primary orthostatic tremor were excluded. Eight patients were identified with idiopathic slow 4–8 Hz orthostatic tremor, which was associated with tremor and dystonia in cervical and upper limb musculature. Coherence analysis in two patients showed findings different to those seen in primary orthostatic tremor. Discussion: Slow orthostatic tremor may be associated with dystonia and dystonic tremor
