The paper, “The Personal Is Political,” was originally published in Notes from the Second Year: Women’s Liberation in 1970 and was widely reprinted and passed around the Movement and beyond in the next several years. I didn’t know just how much it had gotten around until I did a Google search and found it being discussed in many different languages.
Humans harbor diverse microbial communities in and on our bodies, and these can be readily detected in the built environment. Human-associated bacteria disperse into and throughout buildings by three primary mechanisms: (1) direct human contact with indoor surfaces; (2) bioaerosol particle emission from our breath, clothes, skin and hair; and (3) resuspension of indoor dust containing previously shed human skin cells, hair and other bacteria-laden particles. Microbial communities in the built environment are often traced back to an individual person, based on their direct contact with an object, including classroom surfaces and mobile phones. Using our unique Climate Chamber, we measured the airborne bacterial emissions, or “microbial cloud“, of individuals. Most occupants could be clearly detected by their cloud or by settled microbial particles within 1.5 – 4 hours. Our results confirm that an occupied space is microbially-distinct from an unoccupied one, and demonstrate for the first time that individuals release their own personalized microbial cloud.
When physician Adriane Fugh-Berman of Georgetown University School of Medicine in Washington, D.C., was asked to write a review article on interactions between herbs and warfarin, she said maybe. A clinician and expert on herb-drug interactions, Fugh-Berman thought the information could be useful to clinicians who prescribe warfarin as an anticoagulant.
In this modern business world, networking is a crucial component of interactive computer operations. It is difficult to imagine how to exchange data between computers without networks in a world where everything is changing at ever-growing speed. One of the central focal ideas behind hardware virtualization is the possibility to use virtual machines in nearly all cases where physical computers can also be used. Thus, virtual machines must be able to connect to physical and virtual networks with their virtual network adapters. Virtual machines running on VirtualBox can be connected to different networks. VirtualBox provides multiple network modes for virtual machines. Today’s blog post covers VirtualBox network settings to help you configure VirtualBox in the best way possible to suit your needs.
Voters Say Those on the Other Side ‘Don’t Get’ Them. Here’s What They Want Them To Know
Take a quick look at this trout swimming upstream. Notice anything unusual?
You’ve probably seen something similar countless times; the fish wriggles against the currents that push it backwards, slowly making headway until it turns and ducks out of the influence of the stream. Nothing special in that.
The only thing is, this particular fish is dead.
Recently, I came to the conclusion that “Sales are a game of rationales”. Why? Because in order to be a great salesman, you need to be:
- Determined without being arrogant;
- Able to identify your client’s pains and needs, and express them in such a way that you pique their interest within 8 to 30 seconds;
- Asking one relevant question after another, and actively listen to what they have to say;
- And only after you’ve passed through this whole process, can you bring negotiations to the table and, ultimately, close the deal.
In other words, you need skills. That’s why in today’s article, I’ll dive deeper into each competency and how you can develop it. Let’s get started!
Eat poorly, and your body will remember—and possibly pass the consequences onto your kids. In the past several years, mounting evidence has shown that sperm can take note of a father’s lifestyle decisions, and transfer this baggage to offspring. Today, in two complementary studies, scientists tell us how.
A new study shows that empathy may drive rats to help each other. The finding gives insight into the biological roots of our urge to assist others in need. The model the researchers developed will also provide an opportunity for further study.
Learning and motivation are driven by internal and external rewards. Many of our day-to-day behaviours are guided by predicting, or anticipating, whether a given action will result in a positive (that is, rewarding) outcome. The study of how organisms learn from experience to correctly anticipate rewards has been a productive research field for well over a century, since Ivan Pavlov’s seminal psychological work. In his most famous experiment, dogs were trained to expect food some time after a buzzer sounded. These dogs began salivating as soon as they heard the sound, before the food had arrived, indicating they’d learned to predict the reward. In the original experiment, Pavlov estimated the dogs’ anticipation by measuring the volume of saliva they produced. But in recent decades, scientists have begun to decipher the inner workings of how the brain learns these expectations. Meanwhile, in close contact with this study of reward learning in animals, computer scientists have developed algorithms for reinforcement learning in artificial systems. These algorithms enable AI systems to learn complex strategies without external instruction, guided instead by reward predictions.
The contribution of our new work, published in Nature (PDF), is finding that a recent development in computer science – which yields significant improvements in performance on reinforcement learning problems – may provide a deep, parsimonious explanation for several previously unexplained features of reward learning in the brain, and opens up new avenues of research into the brain’s dopamine system, with potential implications for learning and motivation disorders.
