Gender homophily from spatial behavior in a primary school: a sociometric study
We investigate gender homophily in the spatial proximity of children (6 to 12
years old) in a French primary school, using time-resolved data on face-to-face
proximity recorded by means of wearable sensors. For strong ties, i.e., for
pairs of children who interact more than a defined threshold, we find
statistical evidence of gender preference that increases with grade. For weak
ties, conversely, gender homophily is negatively correlated with grade for
girls, and positively correlated with grade for boys. This different evolution
with grade of weak and strong ties exposes a contrasted picture of gender
homophily
Try it on: Voice, concordancing and text-matching in doctoral writing
Appropriate use and acknowledgement of sources continues to be a central concern of academic integrity. A major challenge for research students in using sources is the development of a confident authorial voice that matches disciplinary expectations in language use, yet manages to do so without plagiarising through inappropriate text- matching or recycling of language. This is a daunting challenge for all research writers, particularly for English as an Additional Language (EAL) researchers who are still grappling with English grammar and syntax. In order to develop novice research writers' understanding of acceptable use of sources and mastery of disciplinary language, we have developed a process called "Try it on" that uses concordancing software alongside text-matching software (Turnitin). Here we present textual analyses of two cases using this process: in one, the student's percentage of matches decreased as he developed his authorial voice; in the second, the percentage of matches increased as the student's language choices came to reflect more closely the expected usage in the discipline, thus replicating the expected authorial voice for that particular audience. These cases demonstrate how "Try it on" can be used to help students write in an appropriate authorial voice while also avoiding plagiarism
Characterization of a dense aperture array for radio astronomy
EMBRACE@Nancay is a prototype instrument consisting of an array of 4608
densely packed antenna elements creating a fully sampled, unblocked aperture.
This technology is proposed for the Square Kilometre Array and has the
potential of providing an extremely large field of view making it the ideal
survey instrument. We describe the system,calibration procedures, and results
from the prototype.Comment: 17 pages, accepted for publication in A&
