Maladaptive cognitive appraisals in children with high-functioning autism : associations with fear, anxiety and theory of mind

Despite the well-documented success of cognitive restructuring techniques in the treatment of anxiety disorders, there is still little clarity on which cognitions underpin fear and anxiety in children with high-functioning spectrum disorders (HFASD). This study examined whether certain cognitive appraisals, known to be associated with fear and anxiety in non-HFASD groups, may help explain these emotions in children with HFASD. It also investigated relations between these cognitive appraisals and theory-of-mind (TOM). Using a vignette approach, appraisals, fear and anxiety were assessed in 22 children with HFASD and 22 typically developing (TD) children. The two groups differed significantly on all four appraisal types. Anxiety was negatively correlated with future expectancy and positively with problem-focused coping potential in the HFASD group, but was not correlated with appraisals in the TD group. Emotion-focused coping potential was the only appraisal correlated with fear in the HFASD group and only self-accountability in the TD group. Linear regression analysis found appraisals of emotion-focused coping potential, problem-focused coping potential and future expectancy to be significant predictors of TOM ability in the HFASD group. These findings indicate that specific, problematic patterns of appraisal may characterise children with HFASD

Movement and the Body in Teaching: Challenging the Commonsense Dualism

Much has been written on schools as sites for controlling young people and reproducing particular citizens. As part of these conversations there seems to be a 'commonsense' view that schooling is about educating the mind while at the same time taming the body. The underlying assumption that is being played out in such learning environments reflects that of Cartesian dualism, also referred to as a mind/body dualism and credited to the seventeenth century philosopher, Descartes. I would argue that this dualism is partly responsible for student disengagement with schooling and related to other issues including bullying and disconnection with healthy lifestyles. I am advocating for teachers and schools to interrupt mind/body hierarchies by attending to the embodied learner, a concept that will be unpacked below before suggesting measures to help start this process

Impact of Argument Type and Concerns in Argumentation with a Chatbot

Conversational agents, also known as chatbots, are versatile tools that have the potential of being used in dialogical argumentation. They could possibly be deployed in tasks such as persuasion for behaviour change (e.g. persuading people to eat more fruit, to take regular exercise, etc.) However, to achieve this, there is a need to develop methods for acquiring appropriate arguments and counterargument that reflect both sides of the discussion. For instance, to persuade someone to do regular exercise, the chatbot needs to know counterarguments that the user might have for not doing exercise. To address this need, we present methods for acquiring arguments and counterarguments, and importantly, meta-level information that can be useful for deciding when arguments can be used during an argumentation dialogue. We evaluate these methods in studies with participants and show how harnessing these methods in a chatbot can make it more persuasive

IBM Watson Supporting Space Radiation

The NASA Human Research Program (HRP) Space Radiation (SR) Program Element has been working with IBM Watson Explorer (WEX) to create a tool that allows researchers to search the NASA SR-funded research corpus to help streamline research and maximize efficiency. The entire corpus of publications from research funded by the NASA SR Program Element has been ingested into WEX to allow for examination of: synergies across funded research areas, gaps in research, and collaboration opportunities. This information will be valuable to both scientists and managers as it will allow analysis related to specific scientific questions, inform key decisions and support cross validation of study results. NASA will also evaluate the potential to make WEX publicly available in order to facilitate proposal generation and to enhance collaborations within and across disciplines

Little Things

We present LITTLE THINGS (Local Irregulars That Trace Luminosity Extremes, The HI Nearby Galaxy Survey) that is aimed at determining what drives star formation in dwarf galaxies. This is a multi-wavelength survey of 37 Dwarf Irregular and 4 Blue Compact Dwarf galaxies that is centered around HI-line data obtained with the National Radio Astronomy Observatory (NRAO) Very Large Array (VLA). The HI-line data are characterized by high sensitivity (less than 1.1 mJy/beam per channel), high spectral resolution (less than or equal to 2.6 km/s), and high angular resolution (~6 arcseconds. The LITTLE THINGS sample contains dwarf galaxies that are relatively nearby (less than or equal to 10.3 Mpc; 6 arcseconds is less than or equal to 300 pc), that were known to contain atomic hydrogen, the fuel for star formation, and that cover a large range in dwarf galactic properties. We describe our VLA data acquisition, calibration, and mapping procedures, as well as HI map characteristics, and show channel maps, moment maps, velocity-flux profiles, and surface gas density profiles. In addition to the HI data we have GALEX UV and ground-based UBV and Halpha images for most of the galaxies, and JHK images for some. Spitzer mid-IR images are available for many of the galaxies as well. These data sets are available on-line.Comment: In press in A
