Problems of Practice As Stance

Hyperarticulation as a signal of stance

This study analyzes an episode of a televised political talk show for evidence that speakers hyperarticulate concepts about which they express stances, a use of hyperarticulation that interacts with the discourse function of signaling new information. Using content analysis, utterances were coded on two dimensions: Evaluation (presence or absence of stance-expression) and Novelty (new or given ...

Gearing the Discursive Practice to the Evolution of Discipline: Diachronic Corpus Analysis of Stance Markers in Research Articles’ Methodology Section

Despite widespread interest and research among applied linguists to explore metadiscourse use, very little is known of how metadiscourse resources have evolved over time in response to the historically developing practices of academic communities. Motivated by such an ambition, the current research drew on a corpus of 874315 words taken from three leading journals of applied linguistics in orde...

Practice Midterm Problems

Problem 1. The Internal Revenue Service has studied the frequency of errors in tax form B-6014, a two-page form. The IRS has determined that the probability of an error on the first page is 0.08. Given that the first page has an error, the probability that the second page also has an error is 0.25; given that the first page does not have an error the probability that the second page does is 0.0...

Problem P01: Compute the first N decimal digits after the decimal point of sin(sin(sin 1)), rounded toward zero. We have sin(sin(sin 1)) ≈ 0.678: the first N decimal digits after the decimal point match the first N mantissa digits. We use a target decimal precision N1 > N , and a binary precision p. We compute x = ◦(sin 1), y = ◦(sinx), z = ◦(sin y), with all roundings to nearest. It is easy to...
