EQUILIBRIUM VERSUS DISEQUILIBRIUM IN THE MARKET FOR NON-FED CATTLE

Beef-cow inventory demand is considered in a disequilibrium model of the U.S. live non-fed cattle market. Statistical results indicated the possible presence of disequilibrium prices. However, post-model evaluation indicated that the market for non-fed cattle has not been characterized by significant disequilibrium price behavior.Demand and Price Analysis, Livestock Production/Industries,

Creative Process Beyond the Studio

Creative Process Beyond the Studio In “Creativity: Flow and the Psychology of Discovery and Invention,” psychologist Mihaly Csikszentmihalyi offers the idea that “…creativity does not happen inside people’s heads, but in the interaction between a person’s thoughts and a sociocultural context. It is a systemic rather than an individual phenomenon.” While it remains natural, for many artists, to focus on their individual part in this creativity equation, creative process can involve, and even invite, influence and participation. Artists may work in teams, or partner with community groups, where they serve as facilitators. Artists may take up the role of instigator, prompting public response and participation. Public artists respond to requests for proposals, frequently addressing issues and conditions specified by project funders and constituents. Indeed, some historical periods of exceptional creative productivity can be linked, as Csikszentmihalyi notes of Renaissance Florence, to the intense involvement of an art patronage structure. This panel invites considerations of artwork, artists, and creative process that examine and expand our awareness of their “systemic” inter-relatedness. Submissions are sought from artists and designers, curators and organizers, and historians and critics alike

A sub-product construction of Poincare-Einstein metrics

Given any two Einstein (pseudo-)metrics, with scalar curvatures suitably related, we give an explicit construction of a Poincar\'e-Einstein (pseudo-)metric with conformal infinity the conformal class of the product of the initial metrics. We show that these metrics are equivalent to ambient metrics for the given conformal structure. The ambient metrics have holonomy that agrees with the conformal holonomy. In the generic case the ambient metric arises directly as a product of the metric cones over the original Einstein spaces. In general the conformal infinity of the Poincare metrics we construct is not Einstein, and so this describes a class of non-conformally Einstein metrics for which the (Fefferman-Graham) obstruction tensor vanishes.Comment: 23 pages Minor correction to section 5.

The C-Band All-Sky Survey: Instrument design, status, and first-look data

The C-Band All-Sky Survey (C-BASS) aims to produce sensitive, all-sky maps of diffuse Galactic emission at 5 GHz in total intensity and linear polarization. These maps will be used (with other surveys) to separate the several astrophysical components contributing to microwave emission, and in particular will allow an accurate map of synchrotron emission to be produced for the subtraction of foregrounds from measurements of the polarized Cosmic Microwave Background. We describe the design of the analog instrument, the optics of our 6.1 m dish at the Owens Valley Radio Observatory, the status of observations, and first-look data.Comment: 10 pages, 11 figures, published in Proceedings of SPIE MIllimeter, Submillimeter, and Far-Infrared Detectors and Instrumentation for Astronomy V (2010), Vol. 7741, 77411I-1 - 77411I-1

Assessing the effectiveness and cost effectiveness of subcutaneous nerve stimulation in patients with predominant back pain due to failed back surgery syndrome (SubQStim study): study protocol for a multicenter randomized controlled trial

This is a freely-available open access publication. Please cite the published version which is available via the DOI link in this record.Chronic radicular pain can be effectively treated with spinal cord stimulation, but this therapy is not always sufficient for chronic back pain. Subcutaneous nerve stimulation (SQS) refers to the placement of percutaneous leads in the subcutaneous tissue within the area of pain. Case series data show that failed back surgery syndrome (FBSS) patients experience clinically important levels of pain relief following SQS and may also reduce their levels of analgesic therapy and experience functional well-being. However, to date, there is no randomized controlled trial evidence to support the use of SQS in FBSS.Medtronic Inc
