Postgraduate study: the hidden cost of writing a thesis

Not too many years ago the attitude that: "Women are no good at mathematics, as it is a logical subject which requires a rational mind. As women are irrational, therefore they will not succeed at mathematics or understand it, and therefore should not be encouraged to study it." (McKenzie, 2001) prevailed. Many of these attitudes are fading, but still unseen hurdles exist

Issues in data collection: missing data and the 2001 New Zealand census

Missing data plagues all surveys, and to a degree the New Zealand Census suffers from the same malaise. While it is not a high level of missingness, it is present. If not correctly dealt with; just deleting cases with missing data will lead to biased conclusions, particularly if the missingness mechanism is NMAR. Some missing data may be inevitable; sometimes a respondent may be incapable of answering a question. This is usually MAR. If however the respondent refuses to answer a question because of say having a high income, then the results of the income question will be biased. Over time there have been a growing number of people employing avoidance tactics so as not to be classified as a refusal, but to make enumeration just too difficult. Anecdotal evidence among enumerators shows that this accounts for about 5% of respondents

A visual approach to measuring personality systems

A visual approach to measuring implicit personality systems is explored in this article. Six scales, consisting of optical stimuli (icons), were developed by conducting factor analyses using data from 3 studies with more than 70.000 participants. Internal consistencies and testretest-correlations of the six scales were satisfactory. Incremental validity of the visual scales was examined in 3 studies (N = 232). Results from regression analyses showed that the visual scales are distinct from self-report scales and can explain additional variances in behaviorally anchored rating scales and supervisor ratings. The gain in explained variance beyond selfreport measures was on average 140% in the three studies. The authors conclude that measuring personality dimensions via a visual method can make a significant contribution in explaining implicit information processing and behavior and deserves consideration in applied settings. For example, using visuals that are consistent with implicit versus explicit personality systems of the key audience may deepen our understanding of advertising effectiveness, media use and consumer behavior. --implicit,personality systems interaction,PSI-theory,visual questionnaire (ViQ),Jungian typology

SLIP: 10 years ago and 10 years from now

Founded in 1999, the ACM SLIP Workshop is now in its 12th year. The 2010 SLIP Panel session will highlight perspectives from three individuals who have had great influence on the course of SLIP, and provide an opportunity for lively discussion by workshop attendees of prospects for the next 10 years of SLIP. This panel summary records preliminary thoughts of the panelists on two starting questions
