The Feeding Value of Certain Duck Food Plants of the Bear River Migratory Bird Refuge As Determined By Chemical Analysis

Chemically analyzed a variety of plants from the Bear River Migratory Bird Refuge at intervals throughout the growing season to determine the following constituents: carbohydrates, nitrogen, crude fat, crude fiber, total ash, and the following ash constituents: Ca, P, Mg, Na, K, and Cl

Modeling sources in the FDTD formulation and their use in quantifying source and boundary condition errors

Journal ArticleThe modeling of voltage and current sources as either added or replaced sources in FDTD simulations is described and their differences discussed in terms of a transmission line analogy. An infinitesimal current element (ICE) is used to illustrate the validation of added source modeling and to study the errors involved with modeling an infinitesimal element within the finite-sized FDTD grid. This model is also used to illustrate the behavior of radiation boundary conditions as their near-field position with respect to the source is varied. We characterize the errors due to modeling and boundary conditions and give guidelines for obtaining acceptable accuracy in simulations

On the Job Search and the Wage Distribution

Estimates of the structural parameters of a job separation model derived from the theory of on-the-job search are reported in this paper. Given that each employer pays the same wage to observably equivalent workers but wages are dispersed across employers, the theory implies that an employer's separation flow is the sum of an exogenous outflow unrelated to the wage paid and a job-to-job flow that decreases with the employer's wage. The specification estimated allows worker search effort to depend on the wage currently earned. The empirical results imply that search effort declines with the wage paid, as the theory predicts, using Danish IDA data for the years 1994-1995. Furthermore, the estimates for the full sample and four occupational sub-samples explain the employment effect, defined as the horizontal difference between the distribution of wages earned and the distribution of wages offered.

Effect of Second-Generation Antidepressants on Mania- and Depression-Related Visits in Adults with Bipolar Disorder: A Retrospective Study

Objective: To assess the effect of second-generation antidepressants on mania-related and depression-related office visits for adults with bipolar disorder. Methods: Using a national managed-care claims database, we retrospectively identified continuously enrolled patients with bipolar disorder who had a new antidepressive prescription treatment between January 1998 and December 2002. Patients were followed for at least 12 months after the date of initial use of antidepressant monotherapy, mood stabilizer monotherapy, or antidepressant–mood stabilizer combination therapy. Logit models with propensity score matching were used to identify the relationship between treatment types and the likelihood of having mania-related visits within 12 months. Negative binomial models and Cox proportional hazard models were used to predict the number of depression-related visits and time to first mania- or depression-related visit. Results: Patients on antidepressant monotherapy and combination therapy did not have different likelihoods of mania-related visits compared with those on mood stabilizer monotherapy (with odds ratios (ORs) 0.67 (95% confidence interval (CI) 0.42–1.04) and 0.99 (95% CI 0.69–1.43), respectively). The numbers of depression-related visits for the same comparisons were significantly lower, with incidence rate ratios of 0.68 (95% CI 0.56–0.82) and 0.65 (95% CI 0.52–0.81), respectively. The results of time to first mania- or depression-related visit provided similar indications. Conclusions: Second-generation antidepressant was associated with a decreased number of depression-related visits but was not associated with an increased risk of mania-related visits within a 1-year period. Although more work is needed to establish the safety and efficacy of second-generation antidepressants in treating bipolar depression, the evidence from this study supports a favorable risk–benefit profile
