A few of our favorite unconfirmed ideas
Medical practice is rooted in our dependence on the best available evidence from incremental scientific experimentation and rigorous clinical trials. Progress toward determining the true worth of ongoing practice or suggested innovations can be glacially slow when we insist on following the stepwise scientific pathway, and a prevailing but imperfect paradigm often proves difficult to challenge....
متن کاملOur favorite unproven ideas for future critical care
The future of critical care medicine will be shaped not only by the evidence-validated foundations of science, but also by innovations based on unproven and, in many cases, untested concepts and thoughtful visions of scientists and clinicians familiar with the complex problems actually faced in clinical practice. Clinical investigations and trials often lag behind collective experience and impr...
متن کاملEstablishing an Agile Testing Team: Our Four Favorite "Mistakes"
The authors have spent the past year building a test team in the highspeed, high-change environment of an Internet development company. As we'd hoped, the Agile values helped us tackle the difficulties of testing in such an environment. We also discovered that the Agile values helped us with the politics of working with other teams and obtaining support in the organization.
متن کاملEcological Engineering: Reshaping Our Environments to Achieve Our Goals
Human beings are subject to a range of cognitive and affective limitations which interfere with our ability to pursue our individual and social goals. I argue that shaping our environment to avoid triggering these limitations or to constrain the harms they cause is likely to be more effective than genetic or pharmaceutical modifications of our capacities because our limitations are often the fl...
متن کاملMy favorite cell--Paramecium.
A Paramecium cell has a stereotypically patterned surface, with regularly arranged cilia, dense-core secretory vesicles and subplasmalemmal calcium stores. Less strikingly, there is also a patterning of molecules; for instance, some ion channels are restricted to certain regions of the cell surface. This design may explain very effective and selective responses, such as that to Ca(2+) upon stim...
