  1. Creative Education Exposition, Taiwan, Video Notes Next Article Bookmark and Share

    Video Excerpts: "As now we're in the knowledge economic era, creativity inevitably plays a vital role in a country's competitive advantage. Creativity also gets more public attention than before and is becoming an important issue in Taiwan. All the divisions of Ministry of Education have been making efforts to facilitate the plans that encourage creativity in order to cultivate creative talents among campus and society and make practical of the creativity education plans. Consulting Division in Ministry of Education also implements the middle range plans for the creativity education in Taiwan." (Taiwan Ministry of Education, Creative Education Exposition Proposal)
    Editor's Note: There is considerable creative talent in Taiwan. Unfortunately there was very little effort for "exposition" to the creative world outside of Taiwan/Japan.

  2. The Evolution Of Modern Educational Systems: Distributional Conflict, And Growth, J. Dev. Econ. Next Article Bookmark and Share

    Abstract: We study the evolution of an educational system founded on a hierarchical differentiation between vocational and general education, with vocational playing an inferior role in the society. The dynamics are best summarized by the ratio of the fraction of the population in vocational to that in general education, which we interpret as a measure of the degree of stratification of the society. We show that this ratio first rises and then declines with the level of development, displaying an inverted U-shape which reflects the complex interaction between economic and political forces, including aggregate income growth, wealth inequality and political participation.
  3. Video Game To Help Flood Planners, BBC News Next Article Bookmark and Share

    Excerpts: The planning of the UK's flood defences is to get a helping hand from a 3D virtual world-based computer game.

    FloodRanger, set in a fictional region over a 100-year period, helps planners and engineers work out strategies to cope with real-life flooding.

    As in other virtual world games, like SimCity, players have God-like control, so social, economic and environmental decisions have knock-on effects.

    (...) decide where best to build appropriate sea or river flood defences, like dams, reservoirs or groynes, whilst keeping their public generally happy.

    1. Learning To Play Bayesian Games, Games & Econ. Behav. Next Article Bookmark and Share

      Abstract: This paper discusses the implications of learning theory for the analysis of games with a move by Nature. One goal is to illuminate the issues that arise when modeling situations where players are learning about the distribution of Nature's move as well as learning about the opponents' strategies. A second goal is to argue that quite restrictive assumptions are necessary to justify the concept of Nash equilibrium without a common prior as a steady state of a learning process.

  4. Transitions From Nonliving To Living Matter, Science Next Article Bookmark and Share

    Excerpts: All life forms are composed of molecules that are not themselves alive. But in what ways do living and nonliving matter differ? How could a primitive life form arise from a collection of nonliving molecules? The transition from nonliving to living matter is usually raised in the context of the origin of life. (...) artificial cells (sometimes called protocells) might be quite different from any extant or extinct form of life, perhaps orders of magnitude smaller than the smallest bacterium, and their synthesis need not recapitulate life's actual origins.
    1. Evolutionary Ecology of the Prezygotic Stage, Science Next Article Bookmark and Share

      Abstract: The life cycles of sexually reproducing animals and flowering plants begin with male and female gametes and their fusion to form a zygote. Selection at this earliest stage is crucial for offspring quality and raises similar evolutionary issues, yet zoology and botany use dissimilar approaches. There are striking parallels in the role of prezygotic competition for sexual selection on males, cryptic female choice, sexual conflict, and against selfish genetic elements and genetic incompatibility. In both groups, understanding the evolution of sex-specific and reproductive traits will require an appreciation of the effects of prezygotic competition on fitness.

  5. Avalanche Forecasting Stymied By Unpredictability Of Snow, Natue Science update Next Article Bookmark and Share

    Excerpts: It is still something of a mystery how the strength of snow is determined, however. Researchers generally think that the strength of a material affected by random cracks should decrease as the piece of material gets bigger, as it is then more likely to contain a particularly damaging flaw.

    But Peterlik and colleagues don't find this size-dependence in the strength of snow. This means that its fracture is not controlled solely by random weak spots.

    (...)The breaking of snow is also affected by the shape of snow particles, (...).

  6. Test May Lower Antibiotic Use, Natue Science update Next Article Bookmark and Share

    Excerpts: The unnecessary prescriptions occur because bacterial and viral infections can have similar symptoms, such as sore throat and fever. So clinicians often prescribe antibiotics to err on the side of caution.

    But the more antibiotics are used, the greater the chance that bacteria will evolve to resist them. So many researchers worry that the expensive practice of over-prescription is fuelling the development of superbugs that can't be killed. (...)

    The test works by measuring levels of a protein called procalcitonin in the blood.

  7. The Impact Of Cognitive Complexity On Project Leadership Performance, Info. & Software Tech. Next Article Bookmark and Share

    Abstract: In today's complex development environments, the ability to integrate project components has been found to be a key responsibility for project leaders. This paper reports results of a preliminary experiment examining the importance of cognitive differentiation and integration (i.e. cognitive complexity) to project leadership performance. Results from this preliminary study show the importance of cognitive complexity to success in project leadership. Surprisingly, results suggest that leaders with lower levels of cognitive differentiation abilities (less information fragmentation) perform better on project definition tasks. To this end, we suggest ways to improve complex thinking in project leaders.
    1. Conflict and Cognitive Control, Science Next Article Bookmark and Share

      Excerpts: Cognitive control is necessary when we block a habitual behavior and instead execute a less-familiar behavior. Because cognitive control requires an effort, it is not efficient to maintain a high level of control all the time- the nervous system needs to know when cognitive control is necessary. (...) investigate the brain mechanisms that underlie the recruitment of cognitive control. Two cortical areas in the frontal part of the brain, the anterior cingulate cortex (ACC) and the lateral prefrontal cortex (LPFC), are considered essential for recruiting cognitive control.
  8. Stem Cells Found In Adults May Repair Nerves, ScienceDaily Next Article Bookmark and Share

    Excerpts: It used to be considered dogma that a nerve, once injured, could never be repaired. Now, researchers have learned that some nerves, even nerves in parts of the brain, can regenerate or be replaced. Much of this research focuses on stem cells (...) that can give rise to specialized cells, like neurons. It was once thought that human stem cells were only found in embryos, and in bone marrow, where they produce blood cells. But stem cells are also being found in adults, including the brain and the eye. For example, stems cells steadily replace dead neurons in the olfactory bulb (...).
  9. Maybe It Takes A Bird Brain To Find The Car Keys, Science News Next Article Bookmark and Share

    Excerpts: During a year, each bird buries 22,000 to 33,000 seeds in up to 2,500 locations, and scientists estimate that the bird recovers two-thirds of them up to 13 months later.

    Just how seed cachers do this has fascinated biologists for decades. Scientific investigation of the topic has broadened and deepened in recent years. Cognitive scientists pose seed-storage puzzles to birds as a way of sorting out how their brains work and might resemble our own. Ecologists are looking for links between seed-caching powers and the perils of a species' environment.

    1. Brain Asymmetry And Long-Term Memory, Nature Next Article Bookmark and Share

      Excerpts: Fruitflies that have structurally similar brain hemispheres forget within a matter of hours. The asymmetrical positioning of neural structures on the left or right side of the brain in vertebrates 1,2 and in invertebrates 3,4may be correlated with brain laterality,which is associated with cognitive skills 5.But until now this has not been illustrated experimentally. Here we describe an asymmetrically positionedbrain structure in the fruitfly Drosophilaand find that the small proportion of wild-type flies that have symmetrical brains with two such structures lack a normal long-term memory, although their short-term memory is intact.Our results indicate that brain asymmetry may be required for generating or retrieving long-term memory.
  10. Evaluation Of The Impact Of Prey Behavioural And Ecological Characteristics On Predator Diet, Alphagalileo & Proc. Biol. Sc. Next Article Bookmark and Share

    Abstract: Sociality is believed to be an adaptation to help prey evade predators. If true, prey in larger groups should experience lower predation rates than those in small groups, but there is limited evidence for how predators chose between prey in different sized groups. Additionally, most animals live in environments where they have multiple predators. In this study of predator diets, prey in small terrestrial groups suffered the highest, and arboreal prey in large groups suffered the lowest predation rates. These results suggest that predator and prey behavioural decisions are important for understanding how predation has impacted social evolution.
  11. Where To Start To Launch The 'Butterfly Effect', ScienceDaily Next Article Bookmark and Share

    Excerpts: "Does the flap of a butterfly's wings in Brazil set off a tornado in Texas?" meteorologist Edward Lorenz once asked in postulating the "butterfly effect," (...). In today's world of the Internet the question might be rephrased: Can a single e-mail from Brazil set off a torrent of action in Texas? Groups on the Internet can take many forms, including (...) discussion groups, e-mail mailing lists and links between Web sites on related topics. Most recently, the writers of personal online journals known as Web logs, or "blogs," have begun to link to one another and comment on each other's work.
    1. From Football Conferences To Food Webs: Patterns In Complicated Networks, ScienceDaily Next Article Bookmark and Share

      Excerpts: The world is full of complicated networks that scientists would like to better understand -- human social systems, for example, or food webs in nature. But discerning patterns of organization in such vast, complex systems is no easy task. "The structure of those networks can tell you quite a lot about how the systems work, but they're far too big to analyze (...)." One challenge in making sense of a large network is finding clumps-or communities-of members that have something in common, such as Web pages that are all about the same topic, people that socialize (...).
  12. Effect Of Habitat Complexity On Biological Control By The Red Imported Fire Ant, Biol. Control Next Article Bookmark and Share

    Abstract: (...) can manipulate their abundance with changes in habitat complexity. The most economically significant pests of collards are larvae of the diamondback moth (DBM) (...). Predation of DBM larvae by fire ants was more rapid and efficient in the intercrop than the monocrop. Furthermore, collard leaf damage tended to be inversely related to fire ant density and fire ants were more effective at reducing crop damage in the complex intercrop. Our study indicates the ability of red imported fire ants to be effective biological control agents and suggests that increasing habitat complexity can enhance red imported fire ant efficacy and herbivore control.
  13. Predator-Induced Plasticity In Web-Building Behaviour, Animal Behav. Next Article Bookmark and Share

    Abstract: Many orb-web weaving spiders add conspicuous silken structures, called stabilimenta, to the hub of their webs, which are hypothesized to attract more prey. However, they may also attract predators. Orb spiders should therefore alter their web-building behaviour to minimize predation risk. We tested this hypothesis by experimentally examining web-building responses (...) to predation risk (...). When exposed to predator cues, the juveniles not only decreased the frequency of stabilimentum building but also refrained from increasing stabilimentum area, capture area and capture silk thread (...). This is the first demonstration of an adaptive, plastic web-building behavioural response induced by chemical cues from a predator.
  14. Candy Science: M&Ms Pack More Tightly Than Spheres, Science News Next Article Bookmark and Share

    Excerpts: Using bench experiments and computer simulations, the team has found that squashed or stretched versions of spheres snuggle together more tightly than randomly packed spheres do.

    This surprising result could help scientists better understand the behavior of disordered materials ranging from powders to glassy solids, says Princeton University chemist Salvatore Torquato. The finding could also lead to denser ceramic materials that might make for improved heat shields for furnaces and reduced-porosity glass with exceptional transparency.

    (...) so an ellipsoid nestles close to more neighbors than a sphere does.

    1. Improving the Density of Jammed Disordered Packings Using Ellipsoids, Science Next Article Bookmark and Share

      Excerpts: We suggest that the higher density is directly related to the higher number of degrees of freedom per particle and thus the larger number of particle contacts required to mechanically stabilize the packing. We measured the number of contacts per particle Z 10 for our spheroids, as compared to Z 6 for spheres. Our results have implications for a broad range of scientific disciplines, including the properties of granular media and ceramics, glass formation, and discrete geometry.
  15. Caustic Comments Get Girls A Date, Natue Science update Next Article Bookmark and Share

    Excerpts: Fisher asked 57 women and 47 men to look at pictures of female and male faces, and rate their attractiveness on a seven-point scale from 'extremely unattractive' to 'extremely attractive'.

    Whereas the men were fairly consistent in their voting, the women's votes were slightly, but significantly, affected by the stage of their menstrual cycle. Women about two or three weeks past the first day of their most recent period rated females about half a point lower than women at other points in their cycle.

  16. In Politics, the Web Is a Parallel World With Its Own Rules, NYTimes Next Article Bookmark and Share

    Excerpts: The one-minute spot, (...) did not appear on television, but on President Bush's campaign Web site. And so a new bare-knuckled political use of the World Wide Web showed its head: the Internet attack ad.

    When the Web was in its infancy, Internet utopians envisioned a political revolution, predicting that the new medium would engage and empower voters as never before. Much of what they envisioned has come to pass, with the Internet facilitating vigorous debate this year, most dramatically, giving Howard Dean's campaign the ability to raise millions.

    1. The Search Engine That Isn't a Verb, Yet, NY Times Next Article Bookmark and Share

      Excerpts: Mr. Semel soon realized that the company had helped create a monster. So he has spent $2 billion trying to assemble his own Google, buying Inktomi, the Web search software company, (...).

      Last week, Yahoo finally replaced Google's search results with its home-brewed search engine, which uses a robot, called Slurp, to read Web pages. Experts say Yahoo's new search engine is credible and roughly comparable to Google's. (...) Yahoo appears committed to the sort of engineering work that is needed to improve the quality of Web searches.

    2. Sorting E-Mail Friends From Foes, Natue Science update Next Article Bookmark and Share

      Excerpts: Identifying networks of mutual friends helps filter out spam. The technique exploits the structure of social networks to quickly determine whether a given message comes from a friend or a spammer. The method works for only about half of all e-mails received - but in all of those cases, it sorts the mail into the right category1.(...)

      Boykin and Roychowdhury decided to tackle the problem by taking advantage of the fact that most people's e-mail comes from a limited social network, and these networks tend to be clustered into clumps where everyone knows each other.

  17. Don't Skew The Science, The Globe and Mall Next Article Bookmark and Share

    Excerpts: Some of the most influential scientists in the United States have gone public with disquieting accusations that the Bush administration has suppressed and distorted scientific findings, manipulated research and stacked government advisory panels to suit its political objectives. "When scientific knowledge has been found to be in conflict with its political goals, the administration has often manipulated the process through which science enters into its decisions," the Union of Concerned Scientists said last week after releasing the results of its investigation into the alleged abuses.
    1. Uses and Abuses of Science, NY Times Next Article Bookmark and Share

      Excerpts: On global warming alone, the administration belittled, misrepresented, altered or quashed multiple reports suggesting a clear link between greenhouse gas emissions and the burning of fossil fuels like coal and oil. A study detailing the impact of mercury emissions from power plants was sanitized to industry specifications. Another study (...) was withheld. It does not take much effort to find a pattern of suppressing inconvenient facts that might force Mr. Bush's friends in the oil, gas and coal industries to spend more on pollution control.
      Editor's Note: There are numerous historical examples -from the collapse of Chinese technological superiority to the fall of the communist system- where ideological re-interpretations and selective filtering of empirical facts (treating science as form of literature) provided a clear signature of system instabilities that can lead to bifurcations and paradigm shifts.
  18. Concerns Over US Computer Voting, BBC News Next Article Bookmark and Share

    Excerpts: "The problem with electronic voting is your votes disappear into the electronic machine and there is no independent way to check that those results are valid," said Professor Dill.

    "I know that I am not going to have a lot of confidence in the vote totals reported by those machines unless there is some independent polling or whatever that is consistent with that."

    In recent years there has been a spate of disputes over local election results across the US involving voting machines.

    1. U.S. May Veto Islamic Law In Iraq, USA Today Next Article Bookmark and Share

      Excerpts: Iraq's U.S. administrator suggested Monday he would block any move by Iraqi leaders to make Islamic law the backbone of an interim constitution, which women's groups fear could threaten their rights. (...) During a visit to a women's center in Karbala, administrator L. Paul Bremer said the current draft of the interim constitution, due to take effect at the end of this month, would make Islam the state religion and "a source of inspiration for the law" - but not the main source for that law.
    2. A Third Way for Iraq, NYTimes Next Article Bookmark and Share

      Excerpts: (...)the June 30 date is not inherently significant to Iraqis (...). Washington's initial hope for establishing a transition government in Baghdad by June 30 was pinned on using some sort of nationwide caucus system, but this foundered when Ayatollah Sistani ruled out caucuses as undemocratic. The ayatollah's position is not unreasonable: Iraq's novice electorate needs simplicity and transparency, and it would be hard to find a dozen ordinary Americans outside of Iowa who could explain the caucus system (there is not even an Arabic word for caucus). Editor's Note: Maybe there is also no Arabic word for "Gerrymander".

    1. U.S. Agency Sees Global Network for Bomb Making, NY Times Next Article Bookmark and Share

      Excerpts: Militant Islamic bomb builders have used the same designs for car bombs in Africa, the Middle East and Asia, officials said."Linkages have been made in devices that have been used in different continents,"(...)

      But there are many questions still unanswered about who is behind various bombings, including some of the major suicide bombing attacks in Iraq.(...) believe that Al Qaeda has been weakened by the campaign against terrorism and lacks a central command, as well as financial and recruiting structures. But the bomb investigations suggest that the terrorist network still may be disseminating bomb-making skills to a generation of militants who have fanned out around the world.
