The use of a Classroom Response System (CRS) was evaluated in two sections, A and B, of a large lecture microbiology course. In Section B the instructor used the CRS technology at the beginning of the class period posing a question on content from the previous class. Students could earn extra credit if they answered the question correctly. In Section A, the class also began with an extra credit...

Objective(s) Human papillomavirus (HPV) infections are related to the genesis of various benign lesions and some malignant tumors, but no clear relationship has been identified so far between the subtypes of HPV and skin tag. Materials and Methods The present case-control study was designed to detect the existence of low risk and high risk HPV types in lesions of 50 patients with skin tag (c...

In this paper, we address the problem of generating English tag questions (TQs) (e.g. it is, isn’t it?) in Machine Translation (MT). We propose a post-edition solution, formulating the problem as a multiclass classification task. We present (i) the automatic annotation of English TQs in a parallel corpus of subtitles and (ii) an approach using a series of classifiers to predict TQ forms, which ...

Tag questions are a conspicuous feature of spoken Present-day English. In contrast to many other languages, where tags are generally realized by invariant forms (e.g. nicht wahr? in German, oder? in Swiss German, or n’est-ce pas? in French), the canonical English question tag is a reduced interrogative clause whose structure and lexical content is conditioned by the format of the anchor – or ho...

Most assessments, like the math subtest of the SAT or the GRE, are unidimensional, in that they treat all questions on the test as sampling a single underlying “skill”. Can we predict state tests scores better if we tag the questions with fine-grained models the skills needed? Psychometricians don’t do this presumably because they don’t get better fitting model, for a variety of reasons. We are...
