Working with Nonassociative Geometry and Field Theory

We review aspects of our formalism for differential geometry on noncommutative and nonassociative spaces which arise from cochain twist deformation quantization of manifolds. We work in the simplest setting of trivial vector bundles and flush out the details of our approach providing explicit expressions for all bimodule operations, and for connections and curvature. As applications, we describe the constructions of physically viable action functionals for Yang-Mills theory and Einstein-Cartan gravity on noncommutative and nonassociative spaces, as first steps towards more elaborate models relevant to non-geometric flux deformations of geometry in closed string theory.Comment: 20 pages; v2: Reference added; Contribution to the proceedings of the Corfu Summer Institute on Elementary Particle Physics and Gravity, September 1-26, 2015, Corfu, Greece; Final version published in Proceedings of Scienc

El turismo social como respuesta gubernamental ante la crisis: los principales actores beneficiados

El turismo social se ha convertido en una alternativa gubernamental para poder sortear momentos de crisis. Distintos gobiernos, desde diversas latitudes, apelan a políticas de este tipo tendientes a generar un flujo turístico adicional, que logre compensar las caídas en la demanda comercial, contribuyendo al equilibrio del sector y al desarrollo socio-económico del Estado. Este es el caso del Gobierno argentino en el periodo de la post-crisis del 2001, que, a partir de Programas de Turismo Social, pretende reactivar el turismo doméstico inmerso, desde entonces, en un profundo retroceso. Sustentada en un análisis documental, técnicas de observación participante y entrevistas y encuestas a los distintos actores clave, la investigación desarrollada a continuación logra identificar cuáles son los principales actores beneficiados con el turismo social en este contexto de crisis, así como aquellos otros que quedan relegados de la política gubernamenta

Poisson algebras for non-linear field theories in the Cahiers topos

We develop an approach to construct Poisson algebras for non-linear scalar field theories that is based on the Cahiers topos model for synthetic differential geometry. In this framework the solution space of the field equation carries a natural smooth structure and, following Zuckerman's ideas, we can endow it with a presymplectic current. We formulate the Hamiltonian vector field equation in this setting and show that it selects a family of observables which forms a Poisson algebra. Our approach provides a clean splitting between geometric and algebraic aspects of the construction of a Poisson algebra, which are sufficient to guarantee existence, and analytical aspects that are crucial to analyze its properties

Financing Complexity and Sophistication in Nascent Ventures

Although scholars have considered the financing challenges facing small businesses for some time, little work has focused on financing issues at the venture's nascent stage. In this study, we investigate the sources of funding sought by nascent entrepreneurs and the relationship between the complexity of these funding sources, business plan formalization, and expectations of future firm growth. Using data from the Entrepreneurship Research Consortium/Panel Study of Entrepreneurial Dynamics, we find that nascent entrepreneurs, even those associated with high-growth ventures, favor simple rather than complex sources of funding at the nascent stage. Funding complexity and business plan formalization are also found related to expectation of firm growth. An additional contribution is the development of a funding complexity continuum scale, which should be useful in future studies of nascent as well as later stage entrepreneurial finance and firm growth

The process of drug selection and standardization in small and medium size hospitals of the south region of Santa Catarina, Brazil

Os procedimentos relacionados com o processo de Seleção e Padronização de Medicamentos foram analisados em 25 Farmácias Hospitalares dos Hospitais do sul do estado de Santa Catarina – Brasil. Os dados foram coletados através de questionário estruturado, aplicado in loco na forma de entrevista e posteriormente consolidados pela abordagem metodológica do Discurso do Sujeito Coletivo. Os resultados apontam que nenhum dos hospitais dispõe de Comissão de Farmácia e Terapêutica e em torno de 70% dos hospitais a escolha dos medicamentos é realizada exclusivamente pelos médicos. Em relação à prescrição de medicamentos não padronizados, em 80 % dos casos prevalece o parecer médico e em apenas dois hospitais há uma política pré-estabelecida e consensuada para medicamentos que não façam parte da lista de medicamentos padronizados.The process of selection and standardization of drugs employed by inpatient in 25 small and medium size hospitals of the south region of Santa Catarina has been analyzed. The data were collected by means of a structured questionnaire, applied in loco as an interview with the responsible for the Hospital Pharmacy service. The thematic discourse analysis technique was employed for data analysis. The results pointed out that none of the hospitals has a committee of pharmaceutics and therapeutics and, in about 70% of the hospitals, the drug selection and standardization is carried out exclusively by the physicians. Concerning to the prescription of the non-standardized drugs, in 80 % of the studied cases, the doctor’s opinion prevailed and, in only 2 hospitals, there was a pre-defined and consensual policy for the inclusion of drugs that in the list of standardized ones.Colegio de Farmacéuticos de la Provincia de Buenos Aire

Electrical activation and electron spin resonance measurements of implanted bismuth in isotopically enriched silicon-28

We have performed continuous wave and pulsed electron spin resonance measurements of implanted bismuth donors in isotopically enriched silicon-28. Donors are electrically activated via thermal annealing with minimal diffusion. Damage from bismuth ion implantation is repaired during thermal annealing as evidenced by narrow spin resonance linewidths (B_pp=12uT and long spin coherence times T_2=0.7ms, at temperature T=8K). The results qualify ion implanted bismuth as a promising candidate for spin qubit integration in silicon.Comment: 4 pages, 4 figure

Review: Opportunities and challenges for the genetic selection of dairy calf disease traits.

Interest in dairy cow health continues to grow as we better understand health's relationship with production potential and animal welfare. Over the past decade, efforts have been made to incorporate health traits into national genetic evaluations. However, they have focused on the mature cow, with calf health largely being neglected. Diarrhoea and respiratory disease comprise the main illnesses with regard to calf health. Conventional methods to control calf disease involve early separation of calves from the dam and housing calves individually. However, public concern regarding these methods, and growing evidence that these methods may negatively impact calf development, mean the dairy industry may move away from these practices. Genetic selection may be a promising tool to address these major disease issues. In this review, we examined current literature for enhancing calf health through genetics and discussed alternative approaches to improve calf health via the use of epidemiological modelling approaches, and the potential of indirectly selecting for improved calf health through improving colostrum quality. Heritability estimates on the observed scale for diarrhoea ranged from 0.03 to 0.20, while for respiratory disease, estimates ranged from 0.02 to 0.24. The breadth in these ranges is due, at least in part, to differences in disease prevalence, population structure, data editing and models, as well as data collection practices, which should be all considered when comparing literature values. Incorporation of epidemiological theory into quantitative genetics provides an opportunity to better determine the level of genetic variation in disease traits, as it accounts for disease transmission among contemporaries. Colostrum intake is a major determinant of whether a calf develops either respiratory disease or diarrhoea. Colostrum traits have the advantage of being measured and reported on a continuous scale, which removes the issues classically associated with binary disease traits. Overall, genetic selection for improved calf health is feasible. However, to ensure the maximum response, first steps by any industry members should focus efforts on standardising recording practices and encouragement of uploading information to genetic evaluation centres through herd management software, as high-quality phenotypes are the backbone of any successful breeding programme
