An Introduction to Modern Matrix Methods and Statistics

In this article, using the representation that the Kalman filter recursions in state-space models can be expressed as a matrix-weighted average of prior and sample estimates, we supplement the usual filtering algorithm by an extreme bounds analysis. Specifically, as the covariance matrix of the state error is varied in the class of symmetric and positive-definite matrices, the filtering estimates are shown to be in an ellipsoid.     

Working the circuit: An explanation of employee turnover in the restaurant industry

This study examines the relationship between frequency of viewing television news and crime dramas, and adherence to an ideology of individualism. Attitudes toward women, blacks, and the poor were examined among members of these groups and among white males. Among women and blacks, exposure to television news increases group consciousness, while viewing crime dramas decreases personal efficacy. Among white males, we find an association between exposure to crime drama and endorsement of individual rather than structural causes of inequality. Television news, by contrast, fosters a belief that women's unequal status is due to structural sources.     

Listening—Ubiquitous Yet Obscure

Service learning continues to evolve as an exciting, innovative teaching tool in education. This paper defines and explains the service learning movement and details a service learning unit applied in an “Effective Listening” classroom and the mutual student, institutional, and educator benefits.     

The Thomson ISI Journal Selection Process

Abstract

For more than four decades, Thomson ISI (Institute for Scientific Information) has been committed to a fundamental mission: to provide essential products and services that enable access to and management of the highest quality, most relevant materials for all participants in the research process. In 1958, Dr. Eugene Garfield started ISI by borrowing five hundred dollars from Household Finance. Current Contents^® of Chemical, Phamaco-Medical & Life Sciences was the sole product, covering 286 journals. Today the Thomson ISI database covers more than 16,000 international journals, books, and proceedings in the sciences, social sciences, and arts and humanities. This article describes the processes and standards that result in ISI's abstracting and indexing services. Serials Review 2003; 29:210–212.     

Conference reports

The lack of women engaging themselves in science has been thoroughly discussed in feminist and nonfeminist science studies. It has remained a mystery why so few female students take professional careers as scientists. Though more and more female students enroll in physics studies, for example, they seem to disappear before they reach academic positions. Instead of discussing this as a query of gender inequality in this article, I discuss the more general issues of inclusion and exclusion in communities of practices. I argue that selection mechanisms in a group of students can be connected to their premises for engaging themselves in an activity. As students have different embodied experiences, they also have different premises for engaging themselves. What seems like the same practice can, in fact, be analyzed as practices belonging to different activities. This approach might bring us a small step further in the discussions of the relations between gender and science.     

The Resiliency Model of Role Performance for Service Members,Veterans, and their Families: A Focus on Social Connections and Individual Assets

The Road of Life, a life course metaphor, is used as the backdrop for a theoretically anchored model, The Resiliency Model of Role Performance, which has been developed to account for variation in the ability of service members and their families to meet their role responsibilities in the context of military life and duties. This model incorporates a focus on both individual assets and the social context in which individuals and families are embedded. The model provides a conceptual anchor for the Support and Resiliency Inventory—an online assessment tool for service members and the civilian spouses of service members. Implications for testing the model and its further development are discussed.
