Social Factors Associated with Bulimia Nervosa in College Women

The purpose of this research was to examine the social dimensions of bulimia. Bulimia was viewed using the symbolic interactionist perspective. This perspective was used to see bulimia as a socially constructed line of action. A questionnaire was given to 426 female students at a mid-sized Southern university during the fall of 1994. Crosstabulations and a logistic regression were used to analyze the data. Results suggest that sorority membership, a belief in the importance of avoiding becoming overweight, a belief that one\u27s relationships with men are dependent on being attractive, and low satisfaction with one\u27s social life are related to developing bulimia as a line of action

Modeling Habitat Associations for the Common Loon (\u3cem\u3eGavia immer\u3c/em\u3e) at Multiple Scales in Northeastern North America

Common Loon (Gavia immer) is considered an emblematic and ecologically important example of aquatic-dependent wildlife in North America. The northern breeding range of Common Loon has contracted over the last century as a result of habitat degradation from human disturbance and lakeshore development. We focused on the state of New Hampshire, USA, where a long-term monitoring program conducted by the Loon Preservation Committee has been collecting biological data on Common Loon since 1976. The Common Loon population in New Hampshire is distributed throughout the state across a wide range of lake-specific habitats, water quality conditions, and levels of human disturbance. We used a multiscale approach to evaluate the association of Common Loon and breeding habitat within three natural physiographic ecoregions of New Hampshire. These multiple scales reflect Common Loon-specific extents such as territories, home ranges, and lake-landscape influences. We developed ecoregional multiscale models and compared them to single-scale models to evaluate model performance in distinguishing Common Loon breeding habitat. Based on information-theoretic criteria, there is empirical support for both multiscale and single-scale models across all three ecoregions, warranting a model-averaging approach. Our results suggest that the Common Loon responds to both ecological and anthropogenic factors at multiple scales when selecting breeding sites. These multiscale models can be used to identify and prioritize the conservation of preferred nesting habitat for Common Loon populations

An Infrared Search for Star-Forming Galaxies at z > 2

We report the cumulative results of an on-going near-infrared search for redshifted H-alpha emission from normal galaxies at z>2. An infrared search reduces the bias due to reddening. Using narrow-band imaging with the Near Infrared Camera on the Keck I 10-m telescope, a survey area of almost 12 square arcminutes has been covered. Target regions were selected by matching the redshifts of QSO emission and metal-line absorptions to our available filters. The survey depth is 7E-17 ergs/cm^2/s (3sigma) in H-alpha and K-prime ~22. Eleven H-alpha-emitters, plus two Seyfert I objects, have been discovered. The high density of galaxy detections, corresponding to a co-moving volume density of 0.0135/Mpc^3, makes it unlikely that all of the H-alpha flux in these objects is the result of active nuclei. There is a strong suggestion of clustering in the environments of metal-line absorbers. Each candidate galaxy lies typically within a projected distance of 250kpc of the QSO line of sight and is resolved but compact. The average Star Formation Rate inferred for the galaxies from the H-alpha flux is 50 Msun/yr, significantly higher than current day star-forming galaxies, but consistent with other estimates for galaxies at high redshift.Comment: 39 pages including 17 figures, accepted for publication in Ap

Quality management and quality practice: Perspectives on their history and their future

The purpose of this article and a companion article is to explore a number of topics in Statistics in Business and Industry. This article sketches the history of Quality Management, from its emergence in the late 19th and early 20th centuries through to the present day. Particular emphasis is placed on activities in Japan immediately following the end of the Second World War, and subsequent developments elsewhere in the world. We draw a careful distinction between Quality Management and various methodologies that aid in its implementation, such as Six Sigma. In the words of one management practitioner, Norbert Vogel, ‘TQM in its broadest sense examines all aspects of management and the alternative methodologies being promoted are merely sub-sets of what should be an integrated management system.’ The article concludes with some speculative thoughts about the future of Quality Management from a statistician's point of view.

Conducting Polymers for Neutron Detection

Conjugated polymers have emerged as an attractive technology for large-area electronic applications. As organic semiconductors, they can be used to make large-area arrays of diodes or transistors using fabrication techniques developed for polymer coatings, such as spraying and screen-printing. We have demonstrated both neutron and alpha detection using diodes made from conjugated polymers and have done preliminary work to integrate a boron carbide layer into the conventional polymer device structure to capture thermal neutrons. The polymer devices appear to be insensitive to gamma rays, due to their small physical thickness and low atomic number
