Commentary: The Business of Warfare: Winning Hearts and Minds

Assuming there are business ethics in warfare appears to represent the ultimate irony. There is no doubt that certain business profit from the exploits of war. But when the objectives are reconfigured with the objectives embracing, this is the time when ethical leadership is most in demand

Short Cuts to Spring Vogue

Lady, how about a flower for your lapel? It\u27s being done, you know. These flowers must be handpicked, picked from the superabundance of spring prints

A Handful of Flour

With electricity at her service, woman\u27s brain will change and achieve new capabilities, Thomas Edison predicted 25 years ago. But it was not the introduction of electricity alone that revolutionized household routine

Designs for Richer Living

Stop for a minute on your way through college to become an appreciator of fine art, for it costs nothing and will follow you forever. Every day, unconsciously, as the Iowa State student looks at many beautifully sculptured forms, he is drinking in an education that will become part of his consciousness

Extend the Holiday Hilarity Try a Hotel Party

Yes, the blustering, blaring blasts of January have descended upon us in full fury to dispel the last vestige of our holiday spirit. What\u27s to do about it? That\u27s quite a problem, isn\u27t it? We must provide fun for everyone with the least expenditure of time, money, and muscle

A Nitsche-based cut finite element method for a fluid--structure interaction problem

We present a new composite mesh finite element method for fluid--structure interaction problems. The method is based on surrounding the structure by a boundary-fitted fluid mesh which is embedded into a fixed background fluid mesh. The embedding allows for an arbitrary overlap of the fluid meshes. The coupling between the embedded and background fluid meshes is enforced using a stabilized Nitsche formulation which allows us to establish stability and optimal order \emph{a priori} error estimates, see~\cite{MassingLarsonLoggEtAl2013}. We consider here a steady state fluid--structure interaction problem where a hyperelastic structure interacts with a viscous fluid modeled by the Stokes equations. We evaluate an iterative solution procedure based on splitting and present three-dimensional numerical examples.Comment: Revised version, 18 pages, 7 figures. Accepted for publication in CAMCo

Environmental education in a dual immersion classroom

The research question addressed in this project was, how can environmental education curricula be implemented in dual immersion classrooms? It describes how the author used a unit planning framework designed for dual immersion to adapt lessons from the environmental education curriculum Project WILD for her first grade Spanish immersion class. Both curriculum design and action research were incorporated into the project. She details the process of modifying the lessons, what happened when she implemented the lessons in her classroom, and how the lessons improved students’ content knowledge, language abilities, and appreciation for the environment. She concludes that environmental education can be particularly effective in an immersion setting because of the opportunities for experiential learning and meaningful language practice it provides

Metabolic status of late gestation beef cows and neonatal calves

Two studies were conducted to investigate the changes in beef cattle metabolic status over time. In the first study, the effects of grazing stockpiled tall fescue (STF) versus feeding tall fescue hay during late gestation on nutrient availability for fetal development were investigated over 2 yr. Blood urea nitrogen and plasma glucose were greater in cows grazing STF during late gestation. In yr 1, NEFA was greater on d 56 of study and in yr 2 was greater on d 35, 77, and 99 of study in STF cows. Cows grazing STF tended to have greater thyroxine on d 77 in yr 1. Serum triiodothyronine was less on d 0 but greater on d 99 in cows grazing STF. Cortisol concentrations were greater in STF cows on d 77. Calf birth weight was positively correlated with prepartum maternal BUN and NEFA prior to calving. Results indicate that cows grazing STF had altered metabolic status, which may impact fetal development and calf performance. The objective of the second study was to investigate changes in neonatal calf circulating metabolites and blood chemistry, to determine relationships of metabolites among sampling times, and to determine the relationship between calf vigor and blood chemistry. Circulating plasma glucose, serum BUN, NEFA, and a complete chemistry profile demonstrated changes during the first 72 h postnatally. Sampling times were related at limited hours. Time to stand was correlated with serum BUN, NEFA, and albumin at select sampling hours. In conclusion, neonatal calf metabolic status changes during the first 72 h therefore a consistent blood sampling time is necessary and may be related to vigor after colostrum intake
