Sex at Sea – How to Avoid the Beach Master

by Jim Ryan in Wild Mammals

The southern elephant seal, Mirounga leonina, is a textbook example of an extremely polygynous mammal. As the breeding season begins dominant males fight for control of dozens to hundreds of females on his section of beach real estate (Figure 1). Females within the harem, are monopolized by the dominant male (called a beach master). The beach master is believed to father the vast majority of offspring from his harem females. This system evolved because terrestrial birthing sites (beaches........ Read more »

Inside the mind of a London cabbie

by thesoftanonymous in the.soft.anonymous

If modern London was ancient Athens, London taxi drivers would be worshipped as the Gods of Navigation, appeased only by offerings of fluffy dice and pine-scented air fresheners. Because, before being able to drive one of the legendary black cabs, a wannabe taxi driver must pass a gruelling trial known as ‘The Knowledge’. This consists [...]... Read more »

Early intervention: What's not to like?

September 1, 2011

by Erin Campbell in HighMag Blog

The nuances of the economy are nothing compared with the nuances throughout biology, yet we don’t see our scientists screaming at each other on TV (instead we see researchers versus Jenny McCarthy…ugh!). Researchers take their arguments and evidence to respectable journals and state the facts, which aren’t always in black and white. Today’s stunning image is from a paper that clarifies how actin can prevent AND promote secretion.

Cells use regulated secretion to release certain materi........ Read more »

Prehospital rapid sequence intubation improves functional outcome for patients with severe traumatic brain injury – Summary

by Rogue Medic in Rogue Medic

All EMS RSI patients had waveform capnography, which may explain why the results are so different from the results of the study by Davis on EMS RSI for TBI. This study raised a bunch of questions about those results, which showed worse outcomes for EMS RSI. One hypothesis was that the much higher incidence of hypocapnea contributed to the bad outcomes even though the EMS intubation success rates more than doubled for TBI patients. ... Read more »

Testing the meaning of the Calatagan pot inscriptions

by nath in Imprints of Philippine Science

In my previous post I have presented the ‘tentative’ reading of the Calatagan pot inscription by Guillermo and Paluga [1]. In this post, I write the authors’ test that made them endorse their reading.

The authors think that the reading should be tested by the following: 1) lexical coherence and simplicty; 2) historical emplotment; and 3) sociological mapping or embeddedness.... Read more »

What we should be teaching in interview training

by David Winter in Careers - in Theory

Every now and again during interview coaching, I will stop and ask the client, “What do you think I’m looking for with that question?”. Having read an article by some organisational psychologists at the University of Zurich (Kleinmann et al., 2011), I’m going to ask that question a lot more. In various studies these researchers [...]... Read more »

Men, Women and Spatial Intelligence

by Neuroskeptic in Neuroskeptic

Do men and women differ in their cognitive capacities? It's been a popular topic of conversation since as far back as we have records of what people were talking about.While it's now (almost) generally accepted that men and women are at most only very slightly different in average IQ, there are still a couple of lines of evidence in favor of a gender difference.First, there's the idea that men are more variable in their intelligence, so there are more very smart men, and also more very stupid on........

Is and ought

by Janet Kwasniak in Thoughts on thoughts

There is a piece of wisdom, an ‘is’ can not make an ‘ought’. But also the opposite is true, an ‘ought’ can not make an ‘is’. Just because we feel we ought to have a rational moral sense, does not mean we do have. Just because utilitarianism (least total harm/greatest total benefit) is considered by [...]... Read more »

How old is the Acheulian tool industry and why does it matter?

by zacharoo in Lawn Chair Anthropology

Two views of an Acheulian handaxe adorn the cover of this week's Nature (right). Always happy to see paleoanthropology stuff be classy, front-page news. The cover highlights Christopher Lepre's and colleagues' announcement of what may be the oldest Acheulian tools known.
To recap stone tools: The first good evidence of tool use by humans' ancestors are the Oldowan lithics from the 2.6 million year old site of Gona in Ethiopia (Semaw et al. 2003). McPherron and others (2010) reported 2 possibly-c........ Read more »

Prions and the “science” of zombies

by NerdyOne in Try Nerdy

When I say that prions are one of the coolest biological phenomena in existence, I mean to say that they are one of the most sci-fi and potentially frightening things you could encounter. They are the causative agent behind mad cow disease, which you’ve probably heard of, and which might not seem too terrifying. But the way prions work, and the fact that there is a “human form” of mad cow disease, will be enough to give you the creeps.

Did I mention that prion infection is t........ Read more »

Marsupials Make the Best Medicine

by Elizabeth Preston in Inkfish

We're waging an increasingly desperate war on drug-resistant bacteria. Thanks to their adaptability--and our own fondness for strewing antibiotics everywhere, like inept military commanders who let the enemy borrow and examine our only weapons before we attack--the bugs are gaining ground. Previously life-saving drugs are now useless, and previously beatable infections now have strains that seem immortal.To find new antibiotics that can help us, why not turn to animals that are still doing a goo........

Mesopotamian Religion: Prelude to Axial Age

by Cris Campbell in Genealogy of Religion

Between 800 and 200 BCE, a remarkable series of sages, mystics, and thinkers gave rise to the transcendental traditions that are known today as “world religions.” In 1949, the German philosopher Karl Jaspers identified several themes common to these traditions and described this  six hundred year period as the Axial Age: “These movements were ‘axial’ [...]...

Let me help you with... Time-Based Risk Management

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Today I present you only one chapter of a great book by Wu and Blackhurst: “Managing Supply Chain Risk and Vulnerability” (which can be bought on here).

I especially like the third chapter by Professors Sodhi and Tang on a new approach to managing disruptions: Time-based Risk Management.
The whole book features a more practitioner oriented approach so don’t expect too much focus on the methodological parts.

Reason for risk management
