Professionalizing the Everyday
When I think of tutors’ professionalization, I inevitably consider the texts I encourage tutors to read — not just tutor training manuals but also the theory and research that shape my understanding of our field. One such text that I’ve recently adopted for a new tutor training course is The Everyday Writing Center: A Community of Practice by Anne Geller, Michele Eodice, Frankie Condon, Meg Carroll and Elizabeth Boquet. Although I find this to be one of the most progressive writing center texts in our scholarly canon, it’s likely not on many tutors’ reading lists because it was written ostensibly for writing center administrators. Despite its title, this book’s insights into writing center leadership are not confined to the everyday nuts and bolts of running a center but are also valuable for tutors.University Writing Cente

A new look at microlensing limits on dark matter in the Galactic halo
The motivation for this paper is to review the limits set on the MACHO
content of the Galactic halo by microlensing experiments in the direction of
the Large Magellanic Cloud. This has been prompted by recent measurements of
the Galactic rotation curve, which suggest that the limits have been biassed by
the assumption of an over-massive halo. The paper first discusses the security
of the detection efficiency calculations which are central to deriving the
MACHO content of the Galactic halo. It then sets out to compare the rotation
curves from various halo models with recent observations, with a view to
establishing what limits can be put on an all-MACHO halo. The main thrust of
the paper is to investigate whether lighter halo models which are consistent
with microlensing by an all-MACHO halo are also consistent with recent measures
of the Galactic rotation curve. In this case the population of bodies
discovered by the MACHO collaboration would make up the entire dark matter
content of the Galactic halo. The main result of this paper is that it is easy
to find low mass halo models consistent with the observed Galactic rotation
curve, which also imply an optical depth to microlensing similar to that found
by the MACHO collaboration. This means that all-MACHO halos cannot be ruled out
on the basis of their observations. In conclusion, limits placed on the MACHO
content of the Galactic halo from microlensing surveys in the Magellanic Clouds
are inconsistent and model dependent, and do not provide a secure basis for
rejecting an all-MACHO halo.Comment: 8 pages, 4 figures, accepted for publication in A&

(Un)Complicating Planning and Revising: Metacognition and Problem-Based Tutoring
Why do clients struggle with creating rhetorical plans and globally revising their texts, and how can peer tutors help clients cultivate effective planning and revision practices? Problems with planning and revising differ depending upon the student and the task. Nevertheless, many clients may struggle because they don’t view writing as a problem-solving process that involves addressing a particular audience, selecting and narrowing not only a “topic” but a thesis and support, establishing a purpose for the text, and creating a persona. Instead, clients come to writing with “ideas” for what they want to write about and begin producing text as soon as they feel they have “something to say.” Because clients have paid scant attention to audience, purpose, or persona, as their resulting products show, they have no starting point from which to review how or if their texts have successfully addressed an audience, achieved a purpose, or created an ethos.University Writing Cente

Time Dilation and Quasar Variability
The timescale of quasar variability is widely expected to show the effects of
time dilation. In this paper we analyse the Fourier power spectra of a large
sample of quasar light curves to look for such an effect. We find that the
timescale of quasar variation does not increase with redshift as required by
time dilation. Possible explanations of this result all conflict with widely
held consensus in the scientific community.Comment: 6 pages including 3 figures. Accepted for publication in ApJ Letter
