Strategic Supply Chain Design and the Product-Relationship Matrix

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Yet another case study. This time on strategic network design. Why? A major problem for businesses is to find the right strategy for a given situation. And "right" here means optimal (for a given KPI).
Research question might be: Are there general categories which can be used to make different decision situations comparable? And if yes, what would optimal strategies under these circumstances be?

Seuring (2009) tries to answer the first research question using case studies. From........ Read more »

Sexual selection on the American frontier

by Jason Collins in Evolving Economics

It seems obvious that having multiple wives is a good thing for the fitness of a man. Similarly, having the women in a population monopolised by a small number of men is not good for the fitness of those men who miss out on a mate. In such a society, the large difference in fitness [...]... Read more »

Religious Orthodoxy Does Not Protect Against Disordered Eating

by Arya M. Sharma in Dr. Sharma's Obesity Notes

One of the most persistent and pervasive beliefs amongst experts in eating disorders is that much of this problem in “western” society is promoted by the focus on thinness in popular media and weight-obsessed societal norms.
It is therefore interesting, when researchers find that actual data to support this commonly held notion may not be all [...]... Read more »

Women are soft (and sweet) and men are hard (and tough)

by Rita Handrich in The Jury Room

Here’s a new entry in the embodied cognition research. You remember, it’s the research that leads us to see others as ‘warm’ when we are holding a cup of hot coffee.  There are associations (warm drink = warm person) and there are symbolic meanings (like Pontius Pilate or Lady MacBeth washing their hands). And then. Then [...]

by Erin Campbell in HighMag Blog

Cancer cells are smart little guys, unfortunately. Many cancer therapies target a specific type of cancer cell migration, but many cancer cells are able to switch to a different mode of migration and evade the attack. Today’s image is from a paper looking at these two modes of migration by using 3D cultures of malignant breast cancer cells.Malignant cancer cells are able to spread beyond the initial tumor, and their migration can occur from using either of two types of cancer cell migration........

How structural biology solved a 110-year immunological mystery

by Wellcome Trust in Wellcome Trust Blog

  In December last year, a new research paper revealed how a protein called perforin – the ‘bullet’ of the immune system – kills rogue cells in our body. How these immune pore-forming proteins function has been a key question since the discovery of “haemolytic complement proteins” in the 1890s by the Nobel laureate Jules [...]... Read more »

Article Review: Generational differences in academic EM

by Michelle Lin in Academic Life In Emergency Medicine

Men are from Mars. Women are from Venus.By learning about our differences, we can learn to appreciate and better communicate with those who are different from us.The same falls true for working with residents and faculty from different "generations", as defined as traditionalists, baby boomers, generation Xers, and millennials.This literature review and consensus document is quite extensive and even comes in 2 parts in Academic Emergency Medicine. There is a great summary table of the gener........ Read more »

Know your type

by David Winter in Careers - in Theory

In last week’s post about employability I presented four approaches to employability (Careerist, Ritualist, Rebel and Retreatist). This got me all enthusiastic about typologies that put people into boxes which describe their approach to career management and decision making. I’ve found a few, but I’m hoping that you can come up with some more for [...]... Read more »

Shattered chromosomes cause cancer chaos

by Cancer Research UK in Cancer Research UK - Science Update

At its heart, cancer is caused when our genes – the instructions encoded in the DNA found within our cells – go wrong. Without the correct instructions, cells start to multiply out of control, fail to die when damaged, and begin to spread around the body. Scientists studying the precise nature of these microscopic – [...]... Read more »

Is oxytocin truly a universal social panacea?

by Dr Shock in Dr Shock MD PhD

Oxytocin is the new hormone possibly responsible for increase of trust, “the hormone of love”, and improvement of social cognition. This optimism is sometimes turned around in the way that some researchers believe that oxytocine could also ameliorate social deficits such as present in social phobia and autism. I don’t share this optimism, in biology [...]

Existential Neuroscience

by Psychothalamus in Psychothalamus

Is it reasonable to fear death? If you agree with Lucretius, you will say no. In what is known as the Symmetry Argument, Lucretius contends that that the time before our existence is similar to the time of our future non-existence. And since we do not fear the time before we existed, it is not reasonable to fear our future non-existence i.e. death. ... Read more »

The Mystery of Stiff Person Syndrome

by Neuroskeptic in Neuroskeptic

"Stiff Person Syndrome" (SPS) is a rare neurological disease with a silly name but serious symptoms.Not in fact a disorder caused by an overdose of Viagra, the defining feature of SPS is uncontrollable muscle rigidity, which comes and goes in bouts, but generally gets worse over time. However, other symptoms are seen including depression, anxiety, and other neurological features such as cerebellar ataxia.What causes SPS? Well, it's been known for over 20 years that most SPS patients have antibod........ Read more »

Noise of Aviation

by Frautech in Engineer Blogs

What is it that keeps us awake at night? A new study from the German Aerospace Center on sleep patterns showed the unpredictable noises are the most disturbing to our sleep patterns. Noises like an airplane taking off have a more gradual rise and fall in sound despite lasting longer than the passing of a car. And yet in sleep surveys, people report aircraft noise as disturbing their sleep. The study’s authors speculated this was because a typical sleep cycle lasts 20 minutes and so airplan........

Cannabis Makes Young Men Jumping Mad

by Ultimo167 in Strong Silent Types

Large et al. (2011) add to the mounting evidence that cannabis causes psychosis in young people. Or does it? When using such terminology, I would suggest, defining the actual psychotic experience, experienced, including its demonstrable symptoms, duration and response to treatment, would distinguish one-off freak out events from a lifetime of disabling poor mental health. There are many more such quandaries regarding this rather seductive topic, that are equally begging for resolution. ... Read more »
