© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

This article is part of a For-Discussion-Section of Methods of Information in Medicine about the paper "Biomedical Informatics: We Are What We Publish", written by Peter L. Elkin, Steven H. Brown, and Graham Wright. It is introduced by an editorial. This article contains the combined commentaries invited to independently comment on the Elkin et al. paper. In subsequent issues the discussion can continue through letters to the editor.

This paper describes an application of linear logic programming to the frame problem. This treatment has both practical and conceptual advantages over standard treatments: it is computationally efficient, and this efficiency arises because linear logic respects the identity, or otherwise, of situations.

This paper is concerned. with the contrast between simulation- and deduction-based approaches to reasoning about physical objects. We show that linear logic can give a unified account of both simulation and deduction concerning physical objects; it also allows us to draw a principled distinction between simulation and deduction, since simulations correspond to cut-free proofs, whereas deductions correspond to proofs in general.

This Special Issue commemorates the 60th anniversary of Business & Society with nine rigorous literature reviews that address important societal problems and provide opportunities for theory development in the business and society field; in this introduction we present an overview of the Special Issue. With the theme “Building on Its Past,” the nine articles address a host of contemporary issues, including climate change, wicked problems, business and human rights, human health, certifications standards, the governance of artificial intelligence, stakeholder engagement, stakeholder (...) theory, and corporate political activity. Together, these reviews offer a wealth of suggested themes, theories and approaches that can drive our research forward for the next decades in business and society research and practice. Using the lens of a miner-prospector continuum to categorize the diversity of articles within this special issue, a common theme emerges across the portfolio of reviews: they all call for a more systemic and integrative perspective toward studying the complex interactions that link business and society actors and issues. Building on these findings, we encourage future scholars to fill long-standing researched gaps through a more open systems approach, which supports both contextually sensitive and multi-level and multi-disciplinary approaches to address grand societal challenges. We conclude with specific suggestions as to how business and society scholars might use an open systems approach, including embracing methodologies to address complex causal pathways, theorizing with a view towards spanning external and internal elements of an organization, and reflecting on the temporal and spatial dynamics of complex systems.

Experiential education produces numerous benefits to students in terms of higher order thinking skills such as the ability to evaluate, analyze, and synthesizeinformation , engagement , and work-readiness . Partnering with community organizations provides a means to create experiential education opportunities for students. In this symposium, we discussed three examples of experiential education to promote learning around themes of sustainability, providing a brief outline of the activities, the intended outcomes, and the lessons learned from our experiences. We concluded with a (...) meditation on the importance of working with community partners and managing expectations so that students, the community, and the institutions gain the best possible outcomes when creating town-gown partnerships for sustainability education.
