Length, Weight, and Yield in Channel Catfish, Lake Diane, MI

Background: Channel catfish (Ictalurus punctatus) are important to both commercial aquaculture and recreational fisheries. Little published data is available on length-weight relationships of channel catfish in Michigan. Though there is no record of public or private stocking, channel catfish appeared in Lake Diane between 1984 and 1995 and it has developed into an excellent fishery. 
Materials and Methods: Sport angling provided 38 samples which were weighed and measured (fork length). Fillets were also weighed. The best fit estimates of parameters a and b in the model, W(L) = aLb, were obtained by both linear least-squares (LLS) regression (log(W) = log(a) + b log(L)) and non-linear least-squares (NLLS) regression. Best-fit parameters of an improved model, W(L) = (L/L1)^b, were also determined by NLLS regression; the parameter L1 is the typical length of a fish weighing 1 kg. The resulting best-fit parameters, parameter standard errors, and covariances are compared between the two models. The average relative weight for this sample of channel catfish is also determined, along with the typical meat yield obtained by filleting. 
Results: NLLS regression yields parameter estimates of b = 3.2293 and a = 0.00522. The improved model yields the same estimate for the exponent, b, and a length estimate (parameter L1) of 45.23 cm. Estimates of uncertainty and covariance are smaller for the improved model, but the correlation coefficient is r = 0.995 in both cases. LLS regression produced different parameter values, a = 0.01356 and b = 2.9726, and a smaller correlation coefficient, r = 0.980. On average, catfish in the sample weighed 106.0% of the standard weight, (Brown et al.) and the linear regression (no slope) of fillet yield vs. total weight suggests a typical fillet yield of 28.1% with r = 0.989.
Conclusion: Most of the fish in the sample were above the standard weight, heavier than the 75th percentile for their length. Channel catfish are doing well in Lake Diane and the population is well matched to the food supply. Management should attempt to maintain current population levels. In this case, the improved length-weight model, W(L) = (L/L1)^b, provided lower uncertainties in parameter estimates and smaller covariance than the traditional model.

Cancer-related mortality in people with mental illness

Context: There is a 30% higher case fatality rate from cancer in psychiatric patients even though their incidence of cancer is no greater than in the general population. The reasons are unclear, but if increased cancer mortality were due to lifestyle only, cancer incidence should be similarly increased. Other hypotheses include delays in presentation, leading to more advanced staging at diagnosis, and difficulties in treatment access following diagnosis

Partisanship and Constituency Influences on Congressional Roll-Call Voting Behavior in the US House

This research examines the factors that influence how members of the US House of Representatives vote. Party affiliation of the legislator and constituency interests will be the two main independent variables. The district\u27s constituency characteristics are represented by constituency ideology (\u2796 Presidential vote for Clinton), percent non-white, region, and the median household education. Three models are used to measure congressional voting behavior. The first of which is measured by the rating of the member\u27s vote with the Christian Coalition. The second and third models are derived from the National Journal Ratings of social and economic liberalism of the member\u27s vote

Better, Faster, Stronger: Integrating Archives Processing and Technical Services

The University of Denver’s Penrose Library implemented a consolidated cataloging and archives processing unit for all materials, taking advantage of the structure, workflow design, and staff resources that were already in place for library-wide materials processing: acquisitions, cataloging, binding, and stacks maintenance. The objective of Penrose Library’s integrated approach was to efficiently create metadata that allow searches based on subject relevance rather than on collection provenance. The library streamlined archives processing by integrating digital content creation and management into the materials processing workflow. The result is a flexible, sustainable, and scalable model for archives processing that utilizes existing staff by enhancing and extending the skills of both experienced monographs catalogers and archivists

Maternal Perceptions of Mealtimes: Comparison of Children with Autism Spectrum Disorder and Children with Typical Development

Background: This study examined mealtime techniques reported by mothers of preschool children with Autism Spectrum Disorder (ASD) and mothers of children with typical development (TD). The mothers’ perceived levels of success and sources of information for mealtime techniques were also reported. Method: The participants were 24 mothers of children with ASD (ASD group) and 24 mothers of children with typical development (TD group) between 3 and 6 years of age. The Background Information Survey and the Mealtime Techniques Interview were administered. Results: The ASD group used significantly more techniques in categories of food appearances, restrictive diets, and vitamin/supplement therapy. The TD group used significantly more techniques in the categories of etiquette and negative consequences. Both groups rated techniques similarly with no significant difference between the perceived rate of success for each category. Finally, 91% of mealtime techniques for both groups were parent generated with few from professionals. Conclusion: The results showed that many of the mothers in both groups used similar mealtime techniques and most implemented techniques that were self-generated with generally moderate perception of success. Occupational therapists should collaboratively work with families to increase mealtime success by recommending interventions that are individualized and family centered

Visual narratives and the portrait busts of Edmonia Lewis

Title from PDF of title page, viewed on January 20, 2011.Thesis advisor: Frances Connelly.Vita.Includes bibliographic references (pages 53-58).Thesis (M.A.)--Dept. of Art and Art History. University of Missouri--Kansas City, 2010.This study considers the social and historical significance of the extant portrait busts sculpted by Edmonia Lewis. The Afro-Native American artist is best known for her thematic sculptures such as Forever Free (1867), Hagar (1875), and Death of Cleopatra (1876). The academic attention paid to these works obscures the fact that portrait busts account for over a third of her artistic output. Consequently, Lewis's portrait busts have not received a concentrated analysis. Who were the individuals portrayed? What were their relationships to the artist? Using Lewis's bust of James Peck Thomas (1874), her only existing portrait of an African-American patron as a case study, this study explores these two questions in depth. Drawing primarily from unpublished court documents, Thomas's autobiography as well as newspaper articles, this examination opens a unique window into the individual lives of Lewis's subjects, thereby expanding our knowledge of nineteenth-century American visual and cultural history.College of Arts and SciencesIntroduction -- James Peck Thomas -- Historical Analysis -- Appendixmonographi
