Fostering creativity. A model for developing a culture of collective creativity in science - 0 views

  • Scientific progress depends on both conceptual and technological advances, which in turn depend on the creativity of scientists
  • creative processes behind these discoveries rely on mechanisms that are similar across disciplines as diverse as art and science
  • research into the nature of creativity indicates that it depends strongly on the cultural environment

  • create optimal conditions in a research organization with the aim of enhancing the creativity of its scientific staff
  • Creativity has been traditionally associated with art and literature but since the early twentieth century, science has also been regarded as a creative activity
  • Measuring creativity is a challenging task owing to its complex and elusive nature
  • Measurement of brain activity showed that creativity correlates with two brain states: a quiescent, relaxed state corresponding to the inspiration stage, and a much more active state corresponding to the elaboration stage
  • models of creativity
  • have a common feature: they depend on a balance between analytical and synthetic thinking, and usually describe the creative process as a sequence of phases that alternate between these states
  • Most research on creativity has focused on the individual
  • However, more recent studies suggest that creativity also depends strongly on the social and cultural context
  • breakthroughs depended on collaboration and social support
  • social environment in business organizations affects the creativity of their employees
  • Although creative individuals are essential, the strong link with the environment indicates that creativity might be greatly enhanced by generating a culture that supports the creative process.
  • Many of the interviewees repeatedly emphasized three main qualities necessary to be a good scientist: rigorous intellect, the ability to get the job done and the ability to have creative ideas.
  • almost all interviewees characterized their breakthrough moment as an abrupt leap in understanding
  • Although breakthroughs in science depend on such an ‘internal' conceptual shift, they also rely on ‘external' experimental results. However, most interviewees described their breakthroughs as largely internal:
  • Only two scientists expressed the view that their breakthroughs were purely external events, based on the observation of novel data.
  • intuition
  • must be combined with rational thinking to be effective
  • Although the synthesis of a new concept relies on intuition, which is based on subconscious mental processing, it must be subjected to conscious examination and analysis
  • specific mental skills or attitudes
  • ability to make unexpected connections
  • ability to choose relevant possibilities from an infinite set of irrelevant ones
  • interest in the unknown'
  • enjoyment of the creative process
  • stimulation by interacting with colleagues
  • undoubtedly the most crucial trait for creativity, which thrives on the exchange of ideas
  • The majority felt that the individual and the collective are equally important:
  • what interactions are optimal for creativity
  • The majority of interviewees answered that other people provided them with ‘inspiration to do something new'
  • positive feedback after the emergence of a new idea is almost as important as the inspiration that triggered it
  • collective provides the individual with technical expertise
  • Therefore, scientists would value a culture of interaction and mutual inspiration more highly than access to technology, although the latter is essential for their experiments.
  • At the end of the interviews, each scientist was asked to describe the best possible conditions for generating creativity at a research institute.
  • Cross-fertilization is absolutely essential
  • These results indicate strongly that an interactive environment is the single most important factor for stimulating creativity
  • interacting with people doing very different things
  • interacting with colleagues informally
  • interactions within any institution are strongly affected by its organization
  • Several interviewees described ‘an open hierarchy' as an important factor for creativity
  • hierarchy is based on genuine respect because people are great scientists, but at the same time they're very approachable and open towards what you have to say
  • These results suggest that the best conditions for scientific creativity come with a free-flowing hierarchy and a highly developed culture of interaction to guarantee the exchange of ideas and inspiration.
  • Furthermore, interdisciplinary interactions lead to the generation of new and unusual ideas
  • Finally, because of the freedom to try new things, these ideas can be tested and eventually generate new insights.
  • Creativity can be described as an emergent phenomenon
  • nonlinear phenomena
  • Emergence depends on dynamic interactions between individual agents within the system
  • The importance of a ‘freedom to try new things' and a ‘free-flowing hierarchy' further supports the idea that individual components in an emergent system must be able to interact flexibly without central control
  • During the interviews, it became apparent that although a culture of interaction and creativity exists at EMBL, this itself is not often the subject of discussion. The values on which this culture is based are seemingly implicit rather than explicit
  • Potentially, the EMBL culture of interaction could be strengthened further by consciously expressing and discussing the values on which it is based

Forget the Foundations - In These Times - 0 views

  • Their “actions” didn’t involve writing grant proposals, discussing their concerns with a board of directors or contacting state agencies. They tested water samples themselves, and, in 1979, produced a study revealing high levels of radioactive contamination, a high percentage of pregnancies complicated by excessive bleeding or terminated in abortion and large numbers of children born with birth defects. Despite their work, the Centers for Disease Control and Indian Health Services discredited the study, and WARN wasn’t vindicated until the South Dakota School of Mines substantiated their claims that same year.
  • But unlike Erin Brockovich, this tale of local activists fighting against faceless institutions doesn’t have a happy ending: The Nuclear Regulatory Commission simply raised the level of “acceptable contamination,” and Indian Health Services started providing bottled water in one area. Congress authorized a new water pipeline to the reservation in 2002–only to have the funding diverted by the financial demands of the wars in Iraq and Afghanistan.

  • that foundations perpetuate First World interests and free-market capitalism, thus preserving many of the problems radical activists wish to eradicate, such as the unregulated concentration of wealth.
  • Foundations were created in the early 20th century by multimillionaire robber barons, such as John D. Rockefeller and Andrew Carnegie, to evade corporate and estate taxes.
  • foundations divert money away from the collective tax base
  • who are more interested in supporting milquetoast reformers than social-justice organizations
  • federal and state funding for education and healthcare has shrunk
  • This is a culture of noblesse oblige, Ahn writes, where the “privileged are obliged to help those less fortunate, without examining how that wealth was created or the dangerous implications of conceding such power to the wealthy.”
  • is the power those with money wield over community leaders.
  • consequently realigning their interests (i.e., maintaining their jobs) with maintaining the system
  • This allegiance keeps community leaders from challenging the root causes of social inequities–the social-change work–at the same time that they pedal to keep up by providing for the needs of individuals devastated by institutional exploitation.
  • Kivel concedes this is valuable work, but points out the inherent injustice of this paradigm: “When temporary shelter becomes a substitute for permanent housing, emergency food a substitute for a decent job … we have shifted our attention from the redistribution of wealth to the temporary provision of social services to keep people alive.”
  • University of Southern California Professor Ruth Wilson Gilmore urges contemporary grassroots activists to stop seeking a “pure way of doing things.” “Many are looking for an organizational structure and a resource capability that will somehow be impervious to co-optation,”
  • transitioning from foundation support to a volunteer collective reliant solely on grassroots dollars

All's Not Fair in Science and Publishing | The Scientist Magazine® - 0 views

  • My takeaway lesson was that the safest strategy was to divulge my results only after they were accepted for publication. And I’m sure I’m not the only one who feels this way. Science is too often a cutthroat venture, with publications as the currency for measuring one’s success. But with everyone keeping their findings secret until they have been approved by the peer-review process, aren’t we slowing the course of scientific discovery?
  • Scientists have failed to establish clear mores for crediting discoveries
  • Many believe that false attribution is actually increasing in frequency, likely motivated by the steady decrease in grant-funding rates.

  • If scientific administrators aspire to accelerate innovation by encouraging team science, they must address this issue. Our university system should reward scientists who are honest and fair in their dealings with fellow investigators.  Specific protocols for guiding research and managing disagreements must be designed. Accurate laboratory records should reflect appropriate credit, and websites sponsored by international scientific organizations should be similarly designed to display accurate attribution of preliminary scientific discoveries. In addition, journals could post final drafts of papers before publication, allowing anonymous comments during a probationary period. If a substantive objection arises, the journal should require revisions or even reject the paper.

Places to Intervene in a System by Donella H. Meadows - developer.*, Developer Dot Star - 0 views

  • Folks who do systems analysis have a great belief in "leverage points."

  • an invitation to think more broadly about system change.
  • Numbers ("parameters" in systems jargon) determine how much of a discrepancy turns which faucet how fast.
  • some of which are physically locked in, but most of which are popular intervention points.
  • Probably ninety-five percent of our attention goes to numbers, but there's not a lot of power in them.
  • Not that parameters aren't important—they can be, especially in the short term and to the individual who's standing directly in the flow. But they rarely change behavior. If the system is chronically stagnant, parameter changes rarely kick-start it. If it's wildly variable, they don't usually stabilize it. If it's growing out of control, they don't brake it.
  • Spending more on police doesn't make crime go away.
  • Numbers become leverage points when they go into ranges that kick off one of the items higher on this list.
  • Probably the most common kind of critical number is the length of delay in a feedback loop.
  • A delay in a feedback process is critical relative to rates of change (growth, fluctuation, decay) in the system state that the feedback loop is trying to control.
  • Delays that are too short cause overreaction, oscillations amplified by the jumpiness of the response. Delays that are too long cause damped, sustained, or exploding oscillations, depending on how much too long. At the extreme they cause chaos. Delays in a system with a threshold, a danger point, a range past which irreversible damage can occur, cause overshoot and collapse.
  • delays are not often easily changeable
  • It's usually easier to slow down the change rate (positive feedback loops, higher on this list), so feedback delays won't cause so much trouble
  • Most systems have evolved or are designed to stay out of sensitive parameter ranges. Mostly, the numbers are not worth the sweat put into them.
  • The plumbing structure, the stocks and flows and their physical arrangement, can have an enormous effect on how a system operates.
