Supply Chain Disruptions and Operating Performance

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


I just realized, that up to now I have not written much about why Supply Chain Risk Management should be an important factor many more companies.

Hendricks and Singhal wanted to understand this as well and researched on what effect a missing supply chain risk management can have on a company's performance. They therefore started a research series, the first article was on the "Effect of Supply Chain Glitches on Shareholder Wealth" (mentioned here). And today I have a look at their second a........

Hotheads by nature

by Kevin Mitchell in Wiring the Brain

If some guy spilt your beer by accident, would you punch him in the face? If he was unapologetic, you might at least consider it – you might in fact feel a pretty strong urge to do it. What stops you? Or, if you’re the type who acts on those urges, what doesn’t stop you? New research has found a mutation in one gene that may contribute to these differences in temperament. Self-control is the ability to inhibit an immediate course of action in the pursuit of a longer-term goal or to c........ Read more »

Personality and academic success in med school

by Dr Shock in Dr Shock MD PhD


If you can predict academic success by personality factors, then med schools should consider including measures of these personality factors during their selection process. Mental toughness and stress tolerance are just two that came up. A recent systematic review looked at prospective cohort studies since 2000 on the subject of medical students’ scores on valid [...]

Protein Crystallization, biologics style

by Peter Nollert in Protein Crystallization Blog

Looking beyond your typical day-to-day work and finding out what ‘the rest of the world’ is doing can be a lot of fun. This is one of the reasons I’m enjoying myself so much at the PepTalk 2011 meeting that is currently taking place in San Diego. As I’m learning about the unique challenges faced in protein drug formulations I am quite surprised at the arsenal of analytical techniques that are available to investigate the ‘health’ of a protein prep.

Who is a scientist, I am a scientist: the bees of Blackawton

by Marc Cadotte in The EEB and flow

In discussions of the larger societal implications of scientific findings, the question of who is a scientist is frequently asked. I've talked with with creationists who invoke the authority of someone who has a PhD in a scientific discipline and happens to share their belief of supernatural origins, as a scientific authority. Does the fact that I have a PhD in ecology and evolutionary biology make me scientist or is being scientist something more?This is an important question. It goes to the co........ Read more »

Own Your Actions to Keep New Year’s Resolutions

by Shaheen Lakhan in Brain Blogger

New Year’s Day is really nothing more than an arbitrary day on the calendar, but it does allow people a chance to reflect on their life and their accomplishments. Many people, in turn, promise to change behaviors or circumstances they don’t like in the year ahead. While a lot of resolutions are aimed at living [...]... Read more »

Lupus May Involve Brain Long Before CNS Symptoms

by William Yates, M.D. in Brain Posts

The brain manifestions of systemic lupus erthematosis can be quite variable.  Many patients do not experience any central nervous system symptoms.  Others can be quite disabled by their CNS symptoms including severe depression, psychosis and delirium.  This variability in the brain is not surprising given that lupus involves a variety of other organ systems (i.e. cardiac) with a range of effects specific to individuals with the disorder.  A group of Chinese radiologists and r........

Eta Carinae: Nature’s own Large Hadron Collider

by mithy in The Enlightenment Junkie

To say that Eta Carinae is one of the most remarkable and marvellous stars in the sky is probably an understatement of hyperbolic proportions. It is one of the most fascinating objects in the universe. Not only is it one of the most massive stars in the Universe (weighing approximately 100 solar masses), it is also amongst the [...]...

The Statistical Mechanics of Money

by Joseph Smidt in The Eternal Universe

Yesterday I listened to a talk by Victor Yakovenko of the University of Maryland about the physics of money and it was quite interesting. I think that after this talk I am finally beginning to understand economics while at the same time I suspect that most economists don't.

In his talk he said that back in 2000 he published a paper on how to apply statistical mechanics to free market economics.... Read more »

The Genetical Book Review: Middlesex

by Jon Wilkins in Lost in Transcription

So, welcome to the first installment of Lost in Transcription's newest feature: The Genetical Book Review. For the maiden voyage, we'll cover the 2002, Pulitzer-prize-winning Middlesex by Jeffrey Eugenides.

You're surprised? Because you assume that an eight-year-old Pulitzer winner must already have been reviewed?

Fair enough. But, here's the gimmick: we'll use the genetics angle to talk about some things that have not already been covered extensively elsewhere.

First, tho........ Read more »

Chinese Mothers, American Anxieties and the Nature of Parenting

by David Berreby in Mind Matters


Over the weekend I read Amy Chua's paean to "Chinese parents" in The Wall Street Journal with morbid fascination. What felt morbid was Chua's "Mommie Dearest" anecdote about battling with her 7-year-old because the little girl couldn't master a difficult piano piece (which involved threatening to ...Read More

A biological mechanism that protects against rape?

by BPS Research Digest in BPS Research Digest

When sex researchers compare men and women's genital arousal in response to various stimuli, they generally find that men tend only to be aroused by stimuli that match their declared sexual preferences and subjective feelings, whereas women tend to be aroused by a broad array of sexual material (even involving chimps), irrespective of their declared preferences and subjective feelings. A new study by Kelly Suschinsky and Martin Lalumiere tests the claim, which will surely prove controversial, th........ Read more »

What Was Lost in the Fire: A Conservation Memorial

The latest stop in the #PDEx tour is being hosted by Reconciliation Ecology:The modern conservation movement began at dawn on December 8, 1850, above the north fork of California's San Joaquin river. Soft orange light had just begun to spill over the craggy peaks of the eastern Ahwahnee mountains causing the jagged minarets to ignite like still burning embers from the Indian campfires below. All remained still inside the wigwams of the Ahwahneechee camp. But an attuned ear would have noticed ........ Read more »

Fat Genes Make You Happy?

by Neuroskeptic in Neuroskeptic

Does being heavier make you happier?An interesting new paper from a British/Danish collaboration uses a clever trick based on genetics to untangle the messy correlation between obesity and mental health.They had a huge (53,221) sample of people from Copenhagen, Denmark. It measured people's height and weight to calculate their BMI, and asked them some simple questions about their mood, such as "Do you often feel nervous or stressed?"Many previous studies have found that being overweight is corre........

Cancer Versus the Metabolism

by Daniel Koboldt in Massgenomics

A number of complex biological forces drive the mutation and selection of cancer cells - competitive growth, angiogenesis, immune system evasion, etc. A recent review in the journal Science has shed light on another key aspect of tumor development - the hijacking of the metabolism. Over 80 years ago, Otto Warburg observed that tumor cells [...]... Read more »
