ABSTRACT

Data from focus groups held in Montréal (Canada) with 13 women born in Cameroon, Colombia, and Democratic Republic of Congo were used to explore cancer knowledge among immigrant grandmothers and mothers-in-law and their influence over family cancer-preventative practices. Thematic analysis identified the following leading themes: cancer literacy and influence over family cancer preventative and early detection practices, cancer literacy in relation to family health behaviors, and barriers to accessing health services. Perceived external causes of cancer and its prevention are countered by healthy eating and exercises. Cancer literacy was contextualized by the development of women’s ways of being and doing.     

The Very Model of a Minor/Major Change: A Current Look at Serials Cataloging Title Change Rules

Abstract

This article provides serials professionals with explanations and examples of rules for minor and major changes in the 2002 revision of Anglo-American Cataloguing Rules, 2nd ed. (AACR2), as applied to serials. The authors outline minor/major rules and Library of Congress Rule Interpretations (LCRIs) and give examples for each rule. They also discuss initiatives and meetings leading up to these changes and provide key definitions as well as explore various problems with AACR2 and the intended goals for the revision. Additional discussion focuses on the impact of the minor/major changes on areas such as workflow in technical services, shelving, binding, and training.     

Properties of two tests for outliers in multivariate data

Mardia's multivariate kurtosis and the generalized distance have desirable properties as multivariate outlier tests. However, extensive critical values have not been published heretofore. A published approximation formula for critical values of the kurtosis is shown to inadequately control the type I error rate, with observed error rates often differing from their intended values by a factor of two or more. Critical values derived from simulations for both tests for up to 25 dimensions and 500 observations are presented. The power curves of both tests are discussed. The generalized distance is the more powerful test when exactly one outlier is present and the contaminant is substantially mean-shifted. However, as the number of outliers increases, the kurtosis becomes the more powerful test. The two tests are compared with respect to power and vulnerability to masking. Recommendations for the use of these tests and interpretation of results are given.
