Metrics for text entry research: an evaluation of MSD and KSPC, and a new unified error metric

Abstract: We describe and identify shortcomings in two statistics recently introduced to measure accuracy in text entry evaluations: the minimum string distance (MSD) error rate and keystrokes per character (KSPC). To overcome the weaknesses, a new framework for error analysis is developed and demonstrated. It combines the analysis of the presented text, input stream (keystrokes), and transcribed text. New statistics include a unified total error rate, combining two constituent error rates: the corrected error rate (errors committed but corrected) and the not corrected error rate (errors left in the transcribed text). The framework includes other measures including error correction efficiency, participant conscientiousness, utilised bandwidth, and wasted bandwidth. A text entry study demonstrating the new methodology is described.

Institutionalizing Precarious Immigration Status in Canada

Abstract: This paper analyzes the institutionalized production of precarious migration status in Canada. Building on recent work on the legal production of illegality and non-dichotomous approaches to migratory status, we review Canadian immigration and refugee policy, and analyze pathways to loss of migratory status and the implications of less than full status for access to social services. In Canada, policies provide various avenues of authorized entry, but some entrants lose work and/or residence authorization and end up with variable forms of less-than-full immigration status. We argue that binary conceptions of migration status (legal/illegal) do not reflect this context, and advocate the use of ‘precarious status’ to capture variable forms of irregular status and illegality, including documented illegality. We find that elements of Canadian policy routinely generate pathways to multiple forms of precarious status, which is accompanied by precarious access to public services. Our analysis of the production of...

A Field Experiment Comparing Information-Privacy Values, Beliefs, and Attitudes Across Several Types of Organizations

Abstract: South Bend, IndianaThe present study examined (a) the effect of organizational type (a manipulatedvariable) on individuals' information-privacy values, beliefs, attitudes, and be-havioral intentions and (b) relationships between the same measured variablesSix organizational types were used (1 e, employers, insurance companies, lawenforcement agencies, credit grantors, lending institutions, and the Internal Rev-enue Service) Data on the dependent variables were obtained through the useof structured interviews involving 193 randomly selected residents of a mid-western state Multivanate and univanate analyses revealed (a) significant dif-ferences among the organizational types on information-privacy values, beliefs,and attitudes, and (b) significant correlations between these and other measuredvanables The implications of these findings for organizational and societal policymaking concerning the treatment of information about individuals are discussed

The measurement of postoperative pain: A comparison of intensity scales in younger and older surgical patients

Abstract: The psychometric properties of pain intensity scales for the assessment of postoperative pain across the adult lifespan have not been reported. The objective of this study was to compare the feasibility and validity of the Numeric Rating Scale (NRS), Verbal Descriptor Scale (VDS), and Visual Analog Scale (horizontal (VAS-H) and vertical (VAS-V) line orientation) for the assessment of pain intensity in younger and older surgical patients. At 24h following surgery, 504 patients, who were receiving i.v. morphine via patient-controlled analgesia, completed the pain intensity measures and the McGill Pain Questionnaire (MPQ) in a randomized order. They were asked which scale was easiest to complete, the most accurate measure, and which they would most prefer to complete in the future, as an index of face validity. The amount of opioid self-administered was recorded. Age differences in postoperative pain intensity were not found. However, elderly patients obtained lower MPQ scores and self-administered less morphine than younger people. Psychometric analyses suggested that the NRS was the preferred pain intensity scale. It had low error rates, and higher face, convergent, divergent and criterion validity than the other scales. Most importantly, its properties were not age-related. The VDS also had a favourable profile with low error rates and good face, convergent and criterion validity. Finally, difficulties with VAS use among the elderly were identified, including high rates of unscorable data and low face validity. Its use with elderly postoperative patients should be discouraged.
