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)

Next SectionIn an online study conducted separately in the UK and the US, participants rated the acceptability and fairness of four interventions: two types of financial incentives and two types of medical interventions. These were stated to be equally effective in improving outcomes in five contexts: weight loss and smoking cessation programmes, and adherence in treatment programmes for drug addiction, serious mental illness and physiotherapy after surgery. Financial incentives were judged less acceptable and to be less fair than medical interventions (...) across all five contexts. Context moderated the relative preference between rewards and penalties: participants from both countries favoured rewards over penalties in weight loss and treatment for serious mental illness. Only among US participants was this relative preference moderated by perceived responsibility of the target group. Overall, participants supported funding more strongly for interventions when they judged members of the target group to be less responsible for their condition, and vice versa. These results reveal a striking similarity in negative attitudes towards the use of financial incentives, rewards as well as penalties, in improving outcomes across a range of contexts, in the UK and the USA. The basis for such negative attitudes awaits further study. (shrink)

' a welcome guide for researchers to the merging fields of neuroscience, linguistics and psycholinguistics.' BRAIN'... an important and captivating book, one that has been long awaited by all researchers interested in language and the brain.' Trends in Cognitive Sciences, 1999. The Neurocognition of Language brings together experts on human language and the brain to present the first critical overview of the cognitive neuroscience of language, one of the fastest-moving and most exciting areas today. In-depth discussion of the representations and (...) structures of language, as well as of the cognitive architectures which underlie speaking, listening, and reading, will provide a basis for future brain imaging research. In addition, the existing brain imaging literature on word and sentence processing is critically reviewed, as well as contributions from brain lesion data. Finally, the book discusses the prospects and problems of brain imaging techniques for the study of language, presents some of the most recent and promising analytic procedures for relating brain imaging data to the higher cognitive functions, and contains a review of the neuroanatomical structure of Broca's language area. Uniquely interdisciplinary, this book will provide researchers and students in cognitive neuroscience with state-of-the-art reviews of the major language functions, while being of equal interest to researchers in linguistics and language who want to learn about the neural bases of language. It will be an essential purchase for anyone requiring an overview of our current understanding of the relation between language and the brain. (shrink)

This editorial introduces the Journal of Consciousness Studies special issue on "Animal Consciousness". The 15 contributors and co-editors answer the question "How should we study animal consciousness scientifically?" in 500 words or fewer.

There has been much philosophical interest regarding the ‘hierarchy of evidence’ used to determine which study designs are of most value for reporting on questions of effectiveness, prognosis, and so on. There has been much less philosophical interest in the choice of outcome measures with which the results of, say, an RCT or a cohort study are presented. In this paper, we examine the FDA’s recently published guidelines for assessing the psychometric adequacy of patient-reported outcome measures. We focus on their (...) recommendations for demonstrating content validity and also for how researchers should weigh up the sum of psychometric evidence when choosing these measures. We argue that questions regarding judgment and understanding meaning of these measures should play a more central role in determining their adequacy. (shrink)

Déjà vu is the striking sense that the present situation feels familiar, alongside the realization that it has to be new. According to the Gestalt familiarity hypothesis, déjà vu results when the configuration of elements within a scene maps onto a configuration previously seen, but the previous scene fails to come to mind. We examined this using virtual reality technology. When a new immersive VR scene resembled a previously-viewed scene in its configuration but people failed to recall the previously-viewed scene, (...) familiarity ratings and reports of déjà vu were indeed higher than for completely novel scenes. People also exhibited the contrasting sense of newness and of familiarity that is characteristic of déjà vu. Familiarity ratings and déjà vu reports among scenes recognized as new increased with increasing feature-match of a scene to one stored in memory, suggesting that feature-matching can produce familiarity and déjà vu when recall fails.

This commentary centres around the system of human visual attention. Although generally supportive of the position advocated in the target article, we suggest that the detailed account overestimates the capacities of active human vision. Limitations of peripheral search and saccadic accuracy are discussed in relation to the division of labour between covert and overt attentional processes.

Understanding the relationship between obesity and fast food consumption encompasses a broad range of individual level and environmental factors. One theoretical approach, the health capability framework, focuses on the complex set of conditions allowing individuals to be healthy. This qualitative study aimed to identify factors that influence individual level health agency with respect to healthy eating choices in uniformly constrained environments. We used an inductive qualitative research design to develop an interview guide, conduct open-ended interviews with a purposive sample of (...) 14 student fast food workers, and analyze the data. Data analysis was conducted iteratively during the study with multiple coders to identify themes. Emergent themes included environmental influences on eating behaviors and internal psychological factors. A localized, embedded approach to analyzing the factors driving the obesity epidemic is needed. Addressing contextual interactions between internal psychological and external environmental factors responds to social justice and public health concerns, and may yield more relevant and effective interventions for vulnerable communities.

Until the advent of plastinated cadavers, few outside the medical professions have had firsthand experience with human corpses. Such opportunities are now available at the Body Worlds exhibits of Gunther von Hagens. After an overview of these exhibits, we explore visitor responses as revealed in comment books available upon exiting the exhibit. Cultural, philosophical, and religious issues raised in the comments serve as a microcosm of society at large. The conclusion considers the challenge of such exhibits in introducing the public (...) to science education, notes the image of the body as machine—so prevalent in the West—reflected in visitor comments, and finds hope that the exhibits promote, for many visitors, a sense of community among all humankind.

In the 1990s and early 2000s, “cool’ received substantial scholarly attention, some influential studies claiming that cool was becoming the dominant ethic in contemporary consumer societies, with i...

Researchers now commonly collect biospecimens for genomic analysis together with information from mobile devices and electronic health records. This rich combination of data creates new opportunities for understanding and addressing important health issues, but also intensifies challenges to privacy and confidentiality. Here, we elucidate the “web” of legal protections for precision medicine research by integrating findings from qualitative interviews with structured legal research and applying them to realistic research scenarios involving various privacy threats.

In humans over 15% of X‐linked genes have been shown to ‘escape’ from X‐chromosome inactivation (XCI): they continue to be expressed to some extent from the inactive X chromosome. Mono‐allelic expression is anticipated within a cell for genes subject to XCI, but random XCI usually results in expression of both alleles in a cell population. Using a study of allelic expression from cultured lymphoblasts and fibroblasts, many of which showed substantial skewing of XCI, we recently reported that the expression of (...) genes lies on a contiunuum between those that are subject to inactivation, and those that escape. We now review allelic expression studies from mouse, and discuss the variability in escape seen in both humans and mice in genic expression levels, between X chromosomes and between tissues. We also discuss current knowledge of the heterochromatic features, DNA elements and three‐dimensional topology of the inactive X that contribute to the balance of expression from the otherwise inactive X chromosome.

There are wide individual differences in the ability to detect a stimulus contingency embedded in a complex paradigm. The present study used a cognitive masking paradigm to better understand individual differences related to contingency learning. Participants were assessed on measures of electrodermal arousal and on working memory capacity before engaging in the contingency learning task. Contingency awareness was assessed both by trial-by-trial verbal reports obtained during the task and by a short post-task recognition questionnaire. Participants who became aware had fewer (...) non-specific skin conductance responses and tended to score higher on a digit span assessment. Skin conductance level was not significantly lower in the aware group than in the unaware group. These findings are consistent with studies showing that lower arousal and greater cognitive processing capacity facilitate conscious perception of a greater breadth of information within a scene or a task.
