12:04 PM | Overhead rates on grants and prize money of the Royal Navy in the Napoleonic Wars
Yeah, you read that title right. You know this isn’t going to be a short read. People who aren’t used to writing and running federal grants aren’t probably that familiar with how overhead works. For every dollar you bring in to do work with your grant, your institution gets an additional percentage from the federal [...]

5:41 PM | Friday Roundup: This Week's Wildlife Links (April 19th, 2013)
Awesome camera trap shots of Coyotes in the western United States. Do they look different than the Coyotes we have out east to you too? Or the midwest? How a bottom-dwelling ocean fish was found with birds in its stomach. With pics! An account of how fishing practices and regulations designed to reduce sea turtle mortality affect not only sea turtles, but small-scale commercial fisherpeople in

1:09 PM | Of mites and men
[This post is by Thomas Cameron; I am just putting it up.  -B. ]Those that observe ecological dynamics have always stated that evolution plays a role, but it is only relatively recently that there has been a fever of interest in quantifying what that role might be. It is not the case that there was ever a lack of interest; it was just generally assumed that as evolution occurs on very long timescales, it will have little influence on contemporary ecological dynamics – certainly on the […]

9:50 PM | Separating the grains from the chaff, and all the pests that move with it
Contributed by Melanie Bateman, CABI Switzerland, and Roger Day, CABI Africa While responding to a food crisis in Tanzania in the 1970s, evidence indicates that the larger grain borer (Prostephanus truncatus) was inadvertently introduced into Africa through an infested food aid shipment[1]. Following this introduction and a later introduction in West Africa, the larger grain borer [...]

8:35 PM | Study: Peer-to-peer training can improve safety, knowledge among Hispanic construction workers
Eric Rodriguez and his colleagues at the Latino Union of Chicago quite literally meet workers where they're at — on the city's street corners. Many of the day laborers who gather there are hired to work construction at residential housing sites. Work arrangements are hardly formal and day laborers are frequently subjected to unnecessary and illegal dangers on the job. Unfortunately, worker safety is often kicked to the curb in the street corner marketplace.

guest post by David Tanzer The role of differential equations Last time we looked at stochastic Petri nets, which use a random event model for the reactions. Individual entities are represented by tokens that flow through the network. When the token counts get large, we observed that they can be approximated by continuous quantities, which […]

12:05 PM | Research in community colleges?
The base teaching load at community colleges is typically five lecture courses per semester. They teach nearly as much as K-12 teachers (who have the most challenging and most important job ever). Faculty in community colleges aren’t expected to do research. That doesn’t stop some community college faculty members from doing some research. Heck, there’s [...]

9:17 PM | US industrial sand production increases dramatically, yet industry says worker protection too costly
Since the White House Office of Management and Budget’s (OMB) Office of Information and Regulatory Affairs (OIRA) began reviewing the Labor Department’s proposed rule to reduce by one-half the permissible workplace exposure to respirable crystalline silica more than two year ago, the US has seen a dramatic increase in industrial sand mining, a major route of workers’ exposure to silica dust. Industry groups claim the more-protective standard would be too expensive.

6:01 PM | Who is an author?
When you write a manuscript in any field in academic science, you have to determine who will be an author.  (There is also the question of who is the first and corresponding author, but let’s ignore that for now.) Many a collaborative group has been tripped up by disagreements about this.  It can be a [...]

12:27 PM | Efficient teaching: ungraded quizzes
One principle in teaching is that students need consistent feedback on their performance. They need to know how they’re doing, and use these data to adjust how, and how much, they are studying for a course. The obvious drawback is that frequent assessments take plenty of your time as the instructor — whether in the [...]
