How to Be Omnipresent

Attributions of omnipresence, most familiar within the philosophy of religion, typically take the omnipresence of an entity to either consist in that entity's occupation of certain regions or be dependent upon other of that entity's attributes, such as omnipotence or omniscience. This paper defends an alternative conception of omnipresence that is independent of other purported divine attributes and dispenses with occupation. The resulting view repurposes the metaphysics of necessitism and permanentism, taking omnipresent entities to be those entities that exist at all regions. This view is then shown to best accommodate attributions of omnipresence to a diverse range of metaphysical posits, like abstract entities, and a more diverse class of religious posits

Negotiating Inefficient Compromises: Is Less Better than More?

Significant efforts are made to design and implement decision and negotiation support systems to identify efficient alternatives. The underlying assumption is that decision-makers prefer an efficient alternative over an inefficient one. Experimental studies indicate that people often accept inefficient compromises and are unwilling to improve them even if prompted to do so. This report presents preliminary results for the analysis of 605 bilateral negotiations in which only 20.8% of negotiators who achieved an inefficient compromise entered the post-settlement phase in an attempt to improve the compromise

Prevalence and Antimicrobial Resistance of Salmonella, E. coli, and Campylobacter in Pigs from Swine Producing States in the United States

The purpose of the study was to determine the prevalence and antimicrobial susceptibility of Salmonella, Campylobacter and generic E. coli (commensal bacteria which may harbor antimicrobial resistance genes) from swine feces collected over one year from the top three swine producing states (Iowa, North Carolina, and Minnesota), which represent 51% of the total pig crop in the U.S, plus Ohio. The prevalence of Salmonella (n=462/4426), Campylobacter (n=994/1184) and E. coli (n=833/845) at the sample level was 10.4%, 98.6% and 83.6%, respectively

Yellowism and Ontology: A Skeptical Analysis

When Vladimir Umanets entered the Tate Modern on October 7, 2012 and defaced Rothko\u27s Black on Maroon, he was operating, not as an artist or a vandal, but as a Yellowist. Yellowism is neither art nor anti-art but is instead a supposedly new cultural element that exists for its own sake and is about nothing but the color yellow. It might be tempting to write Yellowism and the Rothko defacement off as a mere prank or as pseudo-intellectual fraud, but I argue that, intentionally or not, the Yellowists have raised issues salient to those invested in both the ontology of art and social ontology more generally. In particular, their actions highlight issues pertaining to the relationship between stipulation and ontology. I explore these issues in this paper

The Carnot Cycle for Small Systems: Irreversibility and the Cost of Operations

We employ the recently developed framework of the energetics of stochastic processes (called `stochastic energetics'), to re-analyze the Carnot cycle in detail, taking account of fluctuations, without taking the thermodynamic limit. We find that both processes of connection to and disconnection from heat baths and adiabatic processes that cause distortion of the energy distribution are sources of inevitable irreversibility within the cycle. Also, the so-called null-recurrence property of the cumulative efficiency of energy conversion over many cycles and the irreversible property of isolated, purely mechanical processes under external `macroscopic' operations are discussed in relation to the impossibility of a perpetual machine, or Maxwell's demon.Comment: 11 pages with 3 figures.

Effects of Thyroxine Exposure on Osteogenesis in Mouse Calvarial Pre-Osteoblasts

The incidence of craniosynostosis is one in every 1,800-2500 births. The gene-environment model proposes that if a genetic predisposition is coupled with environmental exposures, the effects can be multiplicative resulting in severely abnormal phenotypes. At present, very little is known about the role of gene-environment interactions in modulating craniosynostosis phenotypes, but prior evidence suggests a role for endocrine factors. Here we provide a report of the effects of thyroid hormone exposure on murine calvaria cells. Murine derived calvaria cells were exposed to critical doses of pharmaceutical thyroxine and analyzed after 3 and 7 days of treatment. Endpoint assays were designed to determine the effects of the hormone exposure on markers of osteogenesis and included, proliferation assay, quantitative ALP activity assay, targeted qPCR for mRNA expression of Runx2, Alp, Ocn, and Twist1, genechip array for 28,853 targets, and targeted osteogenic microarray with qPCR confirmations. Exposure to thyroxine stimulated the cells to express ALP in a dose dependent manner. There were no patterns of difference observed for proliferation. Targeted RNA expression data confirmed expression increases for Alp and Ocn at 7 days in culture. The genechip array suggests substantive expression differences for 46 gene targets and the targeted osteogenesis microarray indicated 23 targets with substantive differences. 11 gene targets were chosen for qPCR confirmation because of their known association with bone or craniosynostosis (Col2a1, Dmp1, Fgf1, 2, Igf1, Mmp9, Phex, Tnf, Htra1, Por, and Dcn). We confirmed substantive increases in mRNA for Phex, FGF1, 2, Tnf, Dmp1, Htra1, Por, Igf1 and Mmp9, and substantive decreases for Dcn. It appears thyroid hormone may exert its effects through increasing osteogenesis. Targets isolated suggest a possible interaction for those gene products associated with calvarial suture growth and homeostasis as well as craniosynostosis. © 2013 Cray et al

Prevalence of Salmonella in Swine and Pork: A Farm to Consumer Study

Fecal, tissue, and environmental cultures and serological tests were performed on 100 swine on a multi–site farrow to finish production facility. Salmonella of 10 types were identified in the swine herd and environment but none were recovered from rodents or flies caught in the production units. At slaughter, 52% (24 of 46) of swine were serologically positive for Salmonella antibodies, while 9% (4 of 46) were positive by culture. Although clinical salmonellosis was not detected in the study herd, multiple serotypes of Salmonella were causing endemic infections in the study herd
