  1. The Global Competitiveness Report 2003-2004, World Economic Forum Next Article Bookmark and Share

    Excerpts: The GCI is founded on three central ideas.The first one is that the process of economic growth can be analyzed within three important broad categories: the macroeconomic environment, the quality of public institutions, and technology. (...) Informed decisions cannot be made in environments where the inflation rate is in the hundreds.The banking system cannot function if the government runs gigantic deficits.The government cannot provide services efficiently if it has to pay enormous interest rates on its past debts.(...) The second pillar underlying the GCI relates to public institutions. (...)It is important, for example, that property rights are guaranteed by a legal and judicial system. It hard for private companies to operate efficiently in countries where the rule of law is nonexistent or where contracts cannot be enforced. Firms may find it too expensive to do business where corruption is rampant.(...) The third channel is technological progress. Perhaps the main lesson of neoclassical growth theory is that the ultimate source of long-run economic growth is technological progress. The reason for this is that the other potential determinants of growth must run into diminishing returns.

  2. An Environmental Experiment With H2?, Science Next Article Bookmark and Share

    Excerpts: However, the chemicals that we dispose of in the atmosphere often return as unexpected environmental problems--witness the transport sector and local air pollution, halocarbon production and global ozone depletion, and fossil fuel use and global climate change. The seriousness of these problems was not discovered until after the technologies had been introduced, (...). Given the growing interest in an H2 economy, now is the time for assessing its environmental consequences. Three recent publications address how an H2 economy might change the global atmosphere.

    1. Air Pollution And Climate-Forcing Impacts Of A Global Hydrogen Economy, Science Next Article Bookmark and Share

      Excerpts: If today's surface traffic fleet were powered entirely by hydrogen fuel cell technology, anthropogenic emissions of the ozone precursors nitrogen oxide (NOx) and carbon monoxide could be reduced by up to 50%, leading to significant improvements in air quality throughout the Northern Hemisphere. (...) The sign of the change in climate forcing caused by carbon dioxide and methane depends on the technology used to generate the molecular hydrogen. A possible rise in atmospheric hydrogen concentrations is unlikely to cause significant perturbations of the climate system.

  3. There's A Sucker Born In Every Medial Prefrontal Cortex, NYTimes Next Article Bookmark and Share

    Excerpts: (...) growing breed of researchers who are applying the methods of the neurology lab to the questions of the advertising world. Some of these researchers, like Montague, are purely academic in focus, studying the consumer mind out of intellectual curiosity, with no corporate support. Increasingly, though, there are others -- like several of the researchers at the Mind of the Market Laboratory at Harvard Business School -- who work as full-fledged ''neuromarketers,'' conducting brain research with the help of corporate financing and sharing their results with their sponsors.

    1. Aggregate Investment And Political Instability: An Econometric Investigation, Economica Next Article Bookmark and Share

      Abstract: Although in theory the long-run effect of uncertainty on investment is ambiguous, available econometric evidence widely supports a negative association between aggregate investment and political instability. A shortcoming of this body of evidence is that it has failed to investigate the existence and direction of causality between these two variables. This paper fills this gap by testing for such causal and negative long-run relationship between political instability and investment. We find there is a causal relation going from instability to investment, but it is positive and particularly strong in low-income countries. This finding is robust to various sensitivity checks.

    2. The Interactive Minority Game: a Web-based Investigation of Human Market Interactions, Physica A Next Article Bookmark and Share

      Abstract: The unprecedented access offered by the World Wide Web brings with it the potential to gather huge amounts of data on human activities. Here we exploit this by using a toy model of financial markets, the Minority Game (MG), to investigate human speculative trading behaviour and information capacity. Hundreds of individuals have played a total of tens of thousands of game turns against computer-controlled agents in the Web-based Interactive Minority Game. The analytical understanding of the MG permits fine-tuning of the market situations encountered, allowing for investigation of human behaviour in a variety of controlled environments. In particular, our results indicate a transition in players' decision-making, as the markets become more difficult, between deductive behaviour making use of short-term trends in the market, and highly repetitive behaviour that ignores entirely the market history, yet outperforms random decision-making.

  4. Rural Schools Score Above Average In Most States, Brookings News Next Article Bookmark and Share

    Excerpts: The 2003 Brown Center Report on American Education examined rural school performance, including dropout and college application rates, as part of a larger study of national achievement trends. "Nationwide, tens of thousands of rural students are slipping through the cracks in the transition from high school to college," writes Tom Loveless, director of the Brown Center on Education Policy at the Brookings Institution. "The result is the loss of potential for rural youth and a loss of talent for the nation's colleges and universities." -

    1. Cash Incentives For Adoptions Seen As Risk To Some Children, NYTimes Next Article Bookmark and Share

      Excerpts: Once children are formally adopted, for instance, the state is no longer entitled to closely monitor their well-being. And having extended money to the foster parents willing to formally adopt - a greater amount is paid to the families who adopt medically fragile or psychologically troubled children - the risk exists that families take on more than they can handle, sometimes just for the additional money.

  5. A Dynamical Systems Interpretation of Epigenetic Landscapes for Infant Motor Development, Infant Behavior and Development Next Article Bookmark and Share

    Abstract: This paper presents a unified dynamical systems theory of motor learning and development and addresses the normative order and timing of activities in the infant motor development sequence. The emphasis is on the role of intention in modulating the epigenetic landscapes to the emerging forms of infant motor development and how the evolution of attractor landscape dynamics in infancy arises from the multiple time scales of constraints to action. The development of prone progression in infancy is exemplified as a case study and experimental hypotheses of the theory of attractor landscape dynamics and infant motor development are provided.

  6. The Representation Of The Pleasantness Of Flavour, In The Human Brain, Euro. J. Neurosc. Next Article Bookmark and Share

    Abstract: The functional architecture of the central taste and olfactory systems in primates provides evidence that the convergence of taste and smell information onto single neurons is realized in the caudal orbitofrontal cortex (...). These higher-order association cortical areas thus support flavour processing. We performed an event-related fMRI study to investigate where in the human brain these interactions between taste and odour stimuli (administered retronasally) may be realized. These results provide evidence on the neural substrate for the convergence of taste and olfactory stimuli to produce flavour in humans, and where the pleasantness of flavour is represented in the human brain.

  7. Augmentation Of Induced Visual Gamma Activity By Increased Task Complexity, Euro. J. Neurosc. Next Article Bookmark and Share

    Abstract: The current study investigated the modulation of visually induced gamma band oscillations by top-down processes associated with task complexity. Fourteen human subjects performed a reaction time task under two experimental conditions that differed in task complexity. Cortical electrical activity was recorded using a 65 electrode whole scalp electroencephalographic (EEG) net. (...) there was significantly greater energy during the rule-operation condition at approximately 276 ms after the appearance of the stimulus. The results of this study show that top-down processes modulate the level of induced gamma band activity.

  8. Palaeolithic Grandmothers? Life History Theory And Early Homo, J. Royal Anthrop. Inst. Next Article Bookmark and Share

    Abstract: The acknowledged success of early Homo has generally been thought to reflect male-dominated provisioning and associated patterns of co-operative social organization; recently, however, such conclusions have been challenged (...); males, it has been proposed, had a very minor role in food acquisition in early Homo. The fossil record, however, indicates minimal old-age survivorship of either sex and heavy young adult mortality, a pattern which is also seen in larger prehistoric and ethnographic samples. Stone tools, when used to acquire marrow and brain tissue to feed needful youngsters, may also have been among the strategies developed in response to frequent early parental death.

  9. The Nature Of Human Altruism, Nature Next Article Bookmark and Share

    Excerpts: Some of the most fundamental questions concerning our evolutionary origins, our social relations, and the organization of society are centred around issues of altruism and selfishness. Experimental evidence indicates that human altruism is a powerful force and is unique in the animal world. (...). Depending on the environment, a minority of altruists can force a majority of selfish individuals to cooperate or, conversely, a few egoists can induce a large number of altruists to defect. Current gene-based evolutionary theories cannot explain important patterns of human altruism, (...).

    1. Kin Discrimination And The Benefit Of Helping In Cooperatively Breeding Vertebrates, Science Next Article Bookmark and Share

      Abstract: In many cooperatively breeding vertebrates, a dominant breeding pair is assisted in offspring care by nonbreeding helpers. A leading explanation for this altruistic behavior is Hamilton's idea that helpers gain indirect fitness benefits by rearing relatives (kin selection). Many studies have shown that helpers typically provide care for relatives, but relatively few have shown that helpers provide closer kin with preferential care (kin discrimination), fueling the suggestion that kin selection only poorly accounts for the evolution of cooperative breeding in vertebrates. We used meta-analysis to show that (i) individuals consistently discriminate between kin, and (ii) stronger discrimination occurs in species where the benefits of helping are greater. These results suggest a general role for kin selection and that the relative importance of kin selection varies across species, as predicted by Hamilton's rule.

  10. Male Fitness Of Honeybee Colonies, J. Evolutionary Biol. Next Article Bookmark and Share

    Abstract: Honeybees have an extreme polyandrous mating system. Worker offspring of 19 naturally mated queens was genotyped with DNA microsatellites, to estimate male reproductive success of 16 drone producing colonies. This allowed for estimating the male mating success on both the colony level (...). Thus more successful colonies not only produced drones with a higher chance of mating, but also with a significantly higher proportion of offspring sired than drones from less successful colonies. Although the life cycle of honeybee colonies is very female centred, the male reproductive success appears to be a major driver of natural selection in honeybees.

  11. Are We There Yet?, Science Next Article Bookmark and Share

    Excerpts: Of course we are not there yet, if "there" means that genomic information is now a fundamental part of standard medical care. Getting from point A (a gene or genes) to point B (a sick patient) is not as straightforward (...). (...)for certain diseases, such as type II diabetes or alcohol dependence, resources might be better placed in environmental or behavioral interventions that can have a major impact on public health rather than in gene-hunting. In some cases, the roadblocks have arisen from the sheer complexity of the biology,(...).

  12. Genomics And Global Health: Time For A Reappraisal, Science Next Article Bookmark and Share

    Abstract: Although currently there are only a limited number of genomic technologies that are applicable to health care in the developing countries, this is unlikely to be the case in the near future. If, however, the full potential of genomics for health care is to be fulfilled, there will have to be a complete change of emphasis in education and research in the richer countries toward a more global view of disease and its consequences.

    1. Reverse Vaccinology And Genomics, Science Next Article Bookmark and Share

      Excerpts: There have been some discussions lately about the appropriate balance between access to genomic data and global security. The potential of genomic information is enormous for combating microbial agents (both through vaccines and through antimicrobials) that could be used as weapons of bioterrorism. In our view, the awareness that we have the technology to develop vaccines that will render any biological weapon inoffensive is a strong deterrent for bioterrorism. Conversely, restrictions on the sharing of genomic information would represent a recognition of weakness (...).

  13. Humanity As The Model System, Science Next Article Bookmark and Share

    Excerpts: As for predictive medicine, we will require extensive information to analyze the genetic contribution to disease and, at least for the common afflictions, we will need to know the environmental components as well. (...). But these maps will still be at a low resolution, and nothing may come of such experiments if the phenotype description is flawed by incorrect diagnosis and by unresolved multiple genetic effects. (...) we need to have high-resolution information available from many humans and that we need to develop an effective technology to accomplish this.

    1. Pharmacogenetics To Come, Nature Next Article Bookmark and Share

      Excerpts: Genetically selected medicine has been much hyped but has significant potential. Regulation and treatment will depend on pharmaceutical companies more readily sharing genetic data. (...) Clinical pharmacogenetics works on the same principle - that people react individually to different drugs. It is a less light-hearted affair. Every year, hundreds of thousands of deaths worldwide can probably be attributed to the side effects of drugs; and hundreds of thousands of patients will take drugs that for them have no effect at all.

  14. Healthy Animals With Extreme Longevity, Science Next Article Bookmark and Share

    Excerpts: In the nematode Caenorhabditis elegans, mutations that inhibit insulin/IGF-1 (insulin-like growth factor 1) signaling, such as daf-2 insulin/IGF-1 receptor mutations, can double the life-span of the animal. Removing the germ-line precursor cells also extends life-span by approximately 60%. This life-span extension is not a result of sterility; it appears to be due to altered endocrine signaling. Removal of the germ line or the entire reproductive system of daf-2 mutants can further extend life-span: these animals can live four times as long as normal.

    1. Methuselah Worm Remains Energetic For Life, Scientific American.com Next Article Bookmark and Share

      Excerpts: Researchers report in the current issue of the journal Science that variants of the simple worm C. elegans can live 124 days-the equivalent of a human reaching his 500th birthday. The researchers perturbed genes in C. elegans that affect the activity of insulin and removed gonad tissue, which...

    2. High-Tech Daydreamers Investing In Immortality, NYTimes Next Article Bookmark and Share

      Excerpts: He is a geneticist at the University of Cambridge, in England, and his prophecy was straightforward if hard to believe: Getting old and dying are engineering problems. Aging can be reversed and death defeated. People already alive will live a thousand years or longer. He was at pains to argue that what he calls "negligible senescence," and what the average person would call living forever, is inevitable. His proposed war on aging, he said, is intended to make it happen sooner and make it happen right.

  15. A Cellular Framework For Gut-Looping Morphogenesis In Zebrafish, Science Next Article Bookmark and Share

    Abstract: Many vertebrate organs adopt asymmetric positions with respect to the midline, but little is known about the cellular changes and tissue movements that occur downstream of left-right gene expression to produce this asymmetry. Here, we provide evidence that the looping of the zebrafish gut results from the asymmetric migration of the neighboring lateral plate mesoderm (LPM). Mutations that disrupt the epithelial structure of the LPM perturb this asymmetric migration and inhibit gut looping. Asymmetric LPM migration still occurs when the endoderm is ablated from the gut-looping region, suggesting that the LPM can autonomously provide a motive force for gut displacement. Finally, reducing left-sided Nodal activity randomizes the pattern of LPM migration and gut looping. These results reveal a cellular framework for the regulation of organ laterality by asymmetrically expressed genes.

  16. How Legumes Select Their Sweet Talking Symbionts, Science Next Article Bookmark and Share

    Excerpts: Legumes such as soybean, pea, peanut, and alfalfa are able to fix nitrogen because of the bacterial symbionts (rhizobia) that inhabit nodules on their roots. The amount of ammonia produced by rhizobial fixation of nitrogen rivals that of the world's entire fertilizer industry. Consequently, this symbiotic relationship between legumes and rhizobia is of great agronomic and ecological importance. Signals from rhizobial bacteria, called Nod factors (lipochitooligosaccharides), are crucial for initiating the symbiotic response of legumes. This response leads to recognition of bacteria by root-hair cells, (...).

  17. The Enron Pentagon, Brookings Saban Center For Middle East Policy Next Article Bookmark and Share

    Excerpts: Iraq is not just the biggest US military commitment in generations, it is also the biggest market for private military services-ever. Before the war, private firms helped with the invasion's training and planning. During the war, private military employees handled everything from feeding and housing US troops to maintaining our most sophisticated weapons systems, like the B-2 stealth bomber or the Global Hawk UAV. Private firms now play an even more stunning variety of roles in the Iraq occupation. One example is the controversial Dyncorp firm, a Virginia-based company whose employees were implicated in sex crimes in the Balkans; (...)

  18. US Develops Lethal New Viruses, NewScientist Next Article Bookmark and Share

    Excerpts: A scientist funded by the US government has deliberately created an extremely deadly form of mousepox, a relative of the smallpox virus, through genetic engineering. The new virus kills all mice even if they have been given antiviral drugs as well as a vaccine that would normally protect them. (...) The cowpox virus, which infects a range of animals including humans, has been genetically altered in a similar way. (...)also created more deadly forms of mousepox, and has used the same method to engineer a more deadly rabbitpox virus.

      Excerpts: The use of complexity science and its state-of-the-art technologies for research and policy planning purposes is growing rapidly according to a new report just released by the Washington Center for Complexity and Public Policy. This landmark report, The Use of Complexity: A Survey of Federal Departments and Agencies, Private Foundations, Universities, and Independent Education and Reserach Centers, provides a broad overview of the complexity science landscape in Washington, DC and other parts of the United States. The report was prepared at the request of U.S. Secretary of Education Rod Paige.

    2. Calls To Jihad Are Said To Lure Hundreds Of Militants Into Iraq, NYTimes Next Article Bookmark and Share

      Excerpts: Across Europe and the Middle East, young militant Muslim men are answering a call issued by Osama bin Laden and other extremists, and leaving home to join the fight against the American-led occupation in Iraq, according to senior counterterrorism officials based in six countries. The intelligence officials say that since late summer they have detected a growing stream of itinerant Muslim militants headed for Iraq. They estimate that hundreds of young men from an array of countries have now arrived in Iraq by crossing the Syrian or Iranian borders.
      Editor's Note:: Some officials see it as a positive sign that terrorism is fought in Iraq instead of in the U.S. On the other hand, one can see today's occupied Iraq as the world's largest terrorist training camp.

    3. A Willful Ignorance, NYTimes Next Article Bookmark and Share

      Excerpts: Surely it's important to understand how others see us, but a new, post 9/11 version of political correctness has made it difficult even to discuss their points of view. Any American who tries to go beyond "America good, terrorists evil," who tries to understand - not condone - the growing world backlash against the United States, faces furious attacks delivered in a tone of high moral indignation. The attackers claim to be standing up for moral clarity, (...). But they are really being used in a domestic political struggle.

    4. Preventing Nuclear And Radiological Terrorism, Brookings Views Next Article Bookmark and Share

      Excerpts: There is no single solution to the terrifying possibility of nuclear and radiological terrorism. Still, that has not stopped many from trying to pinpoint one. Some have proposed a strong focus on controlling nuclear and radiological materials in cooperative countries, particularly in the states of the former Soviet Union. Others have emphasized the need to challenge so-called rogue states, like Iraq, which might actively supply dangerous weapons to terrorists. Still others have argued that homeland security, understood narrowly as a mix of border controls, domestic surveillance, and emergency response capacity, should be the primary means of addressing the threat. To be successful, though, a strategy must combine these three approaches.

      Absract: This paper examines terrorist "fluids" as complex adaptive systems. The principles of agent-based modeling are applied to global terrorism as a basis for developing agent-based models of terrorist behavior. Recommendations for agent-based models of terrorist behavior as policy analytic tools are presented.
