OBJECTIVE To develop and map indices to illustrate variation in the cost and availability of healthy food. DESIGN Two contiguous wards in London were selected by virtue of their high Carstairs deprivation scores. A 2-km area was defined around a randomly chosen central point. All retail outlets selling food within the area were visited and their location(More)
In computer science, students could benefit from exposure to critical programming concepts from multiple perspectives. Peer review is one method to allow students to experience authentic uses of the concepts in a non-programming manner. In this work, we examine the use of the peer review process in early, object-oriented, computer science courses as a way(More)
In introductory computer science courses, the Unified Modeling Language (UML) is commonly used to teach basic object-oriented design. However, there appears to be a lack of suitable software to support this task. Many of the available programs that support UML focus on developing code and not on enhancing learning. Programs designed for educational use(More)
(ABSTRACT) In computer science, students could benefit from more opportunities to learn important, high-level concepts, to perform professional activities, and to improve their learning skills. Peer review is one method to encourage this but it is not commonly used in the discipline. Peer review provides students with both the opportunity to evaluate other(More)
OBJECTIVE To assess the long-term crossover (CO) rate in men undergoing watchful waiting (WW) as a primary treatment strategy for their asymptomatic or minimally symptomatic inguinal hernias. BACKGROUND With an average follow-up of 3.2 years, a randomized controlled trial comparing WW with routine repair for male patients with minimally symptomatic(More)
In this paper we present our experience using code reviews in a CS2 course. In particular, we highlight a series of misunderstandings of object-oriented (OO) concepts we observed as a by-product of the code review exercise. In our activity, we asked students to review code, rate it using a rubric, and to justify their explanation. The students were asked to(More)
Burkitt's lymphomas (BLs) acquire consistent point mutations in a conserved domain of Myc, Myc Box I. We report that the enhanced transforming activity of BL-associated Myc mutants can be uncoupled from loss of phosphorylation and increased protein stability. Furthermore, two different BL-associated Myc mutations induced similar gene expression profiles(More)
This paper presents our evaluation of using a Tablet-PC to provide peer-review comments in the first year Computer Science course. Our exploration consisted of an evaluation of how students write comments on other students' assignments using three different methods: pen and paper, a Tablet-PC, and a desktop computer. Our ultimate goal is to explore the(More)
BACKGROUND Diabetic dermopathy is the most common specific cutaneous finding in diabetes. OBJECTIVE Using laser Doppler technology, we tested the hypothesis that diabetic dermopathy arises from abnormal local skin blood flow. METHODS We measured cutaneous blood flow in patients with type 1 diabetes without dermopathy and compared values with those in a(More)
