Over the past decade, thousands of patents have seen granted for what are called business methods.Amazon com received one for its“one-click”online payment system Merrill Lynch got legal protection for an asset allocation strategy.One inventor patented a technique for lying a box。Now the nations top patent court appears completely ready to scale hack on business-method patents, which have been controversial ever since they were first authorized 10 years ago. In a move that has intellectual-property lawyers abuzz the U.S court of Appeals for the federal circuit said it would use particular case to conduct a broad review of business-method patents. In re Bilski, as the case is known, is “a very big deal”， says DermisD, Crouch of the University of Missouri School of law.It “has the potential to eliminate an entire class of patents”Curbs on business-method claims would be a dramatic about-face because it was the federal circuit itself that introduced such patents with is 1998 decision in the so-called state Street Bank case, approving a patent on a way of pooling mutual-fund assets. That ruling produced an explosion in business-method patent filings, initially by emerging internet companies trying to stake out exclusive pints to specific types of online transactions. Later, move established companies raced to add such patents to their files, if only as a defensive move against rivals that might bent them to the punch. In 2005, IBM noted in a court filing that it had been issued more than 300 business-method patents despite the fact that it questioned the legal basis for granting them. Similarly, some Wall Street investment films armed themselves with patents for financial products, even as they took positions in court cases opposing the practice。The Bilski case involves a claimed patent on a method for hedging risk in the energy market. The Federal circuit issued an unusual order stating that the case would be heard by all 12 of the courts judges, rather than a typical panel of three, and that one issue it wants to evaluate is whether it should “reconsider” its state street Bank ruling。The Federal Circuits action comes in the wake of a series of recent decisions by the supreme. Count that has narrowed the scope of protections for patent holders. Last April, for example the justices signaled that too many patents were being upheld for “inventions” that are obvious. The judges on the Federal circuit are “reaction to the anti-patent trend at the supreme court” says Harole C Wegner, a par tend attorney and professor at Washington University Law School。Text 3In his book The Tipping Point Malcolm Aladuell argues that social epidemics are driven in large part by the acting of a tiny minority of special individuals, often called influentials who are unusual informed, persuasive, or we connect. The idea is intuitively compelling but it doesnt explain how ideas actually spread。The supposed importance of influentials derives from a plausible sounding but largely untested theory called the tow-step flow of communication. Information flows from the media to the influentials and from them to everyone else. Marketers have embraced the two-step flow became it suggests that if they can just find and influence the influentials, those select people will do most of the work for them. The theory also seems to explain the sudden and unexpected popularity of people was wearing, promoting or developing whatever it is before anyone else paid attention. Anecdotal evidence of this kind fits nicely with the idea that only certain special people call drive trends。In their recent work, however, some researchers have come up with the finding that influentials have far less impact on social epidemics than is generally supposed. In fact , they dont seem to be required of all. The researchers argument stems from a simple observation about social influence, with the exception of a few celebrities like Oprah Winfrey-whose outsize presence is primarily a function of media, not interpersonal influence-even the most influential members of a population simply dont interact with that many others. Yet it is precisely these non-celebrating influentials who according to the two-step-flow theory are supposed to drive social epidemics by influencing their friends and colleagues directly. For a social epidemic to occur however each person so affected must then influence his or her own acquaintances, who must in turn influence theirs and so on and just how many others pay attention to each of these people has little to do with the initial influential. If people in the network just two degrees removed from the initial influential prove resistant, for example from the initial influential, prove resistant, for example the cascade of change wont propagate very far or affect many people。Building on the basic truth about interpersonal influence, the researchers studied the dynamics of populations manipulating a number of variables relating of populations, manipulating a number of variables relating to peoples ability to influence others and their tendency to be。Text 4Bankers have been blaming themselves for their troubles in public. Behind the scenes, they have been taking aim at someone else the accounting standard-setters. Their rules, moan the banks, have forced them to report enormous losses, and its just not fair. These rules say they must value some assets at the price a third party would pay, not the price managers and regulators would like them to fetch。Unfortunately, banks lobbying now seems to be working. The details may be unknowable, but the independence of standard-setters, essential to the proper functioning of capital markets, is being compromised. And, unless banks carry toxic assets at prices that attract buyers, reviving the banking system will be difficult. After a bruising encounter with Congress, Americas Financial Accounting Standards Board (FASB) rushed through rule changes. These gave banks more freedom to use models to value illiquid assets and more flexibility in recognizing losses on long0term assets in their income statement. Bob Herz, the FASBs chairman, cried out against those who “question our motives。” Yet bank shares rose and the changes enhance what one lobby group politely calls “the use of judgment by management。”European ministers instantly demanded that the International Accounting Standards Board (IASB) do likewise. The IASB says it does not want to act without overall planning, but the pressure to fold when it completes it reconstruction of rules later this year is strong Charlie McCreevy, a European commissioner, warned the IASB that it did ”not live in a political vacuum” but” in the real word” and the Europe could yet develop different rules。It was banks that were on the wrong planet, with accounts that vastly overvalued assets. Today they argue that market prices overstate losses, because they Largely reflect the temporary illiquidity of markets, not the likely extent of bad debts. The truth will not be known for years. But banks shares trade below their book value, suggesting that investors are skeptical. And dead markets partly reflect the paralysis of banks which will not sell assets for fear of booking losses, yet are reluctant to buy all those supposed bargains。To get the system working again, losses must be recognized and dealt with. Americas new plan to buy up toxic assets will not work unless banks mark assets to levels which buyers find attractive. Successful markets require independent and even combative standard-setters. The FASB and IASB have been exactly that, cleaning up rules on stock options and pensions, for example, against hostility interests. But by giving in to critics now they are inviting pressure to make more concessions。One basic weakness in a conservation system based wholly one economic motives is that most members of the land community have no economic value Yet these creatures are members of the biotic community and , if its stability depends on its intensity, they are entitled to continuanceWhen one of these noneconomic categories is threatened and if we happen to love it. We invert excuses to give it economic importance At the beginning of century songbirds were supposed to be disappearing。(46)Scientists jumped to the rescure with some distinctly shaky evidence to the effect the insects would eat us up if birds failed to control them the evidence had to be cambric in order to be valid。It is painful to read these round about accounts today. We have no land ethic yet. (47)but we have at least drawn near the point of admitting that birds should continue as a matter of intrinsic right regardless of the presence of absence of economic advantage to us。A parallel situation exists in respect of predatory mammals and fish-eating birds(48)Time was when biologists somewhat over worded evidence that these creatures preserve the health of game by killing the physically weak or that they prey only on “worthless species”。Some species of tree have been read out of the party by economic minded foresters they grow too slowly or have too low a sale vale to pay as imeber crops (49)In Europe, where forestry is ecologically more advanced ,the non-commercial tree species are recognized as members of native forest community, to be preserved as such, within reason。To sum up, a system of conservation based solely on economic self-interest is hopelessly lopsided. (50)It tends to ignore, and thus eventually to eliminate, many elements in the land community that lack commercial value, but that are essential to its healthy functioning. Without the uneconomic pats。Text 1Habits are a funny thing. We reach for them mindlessly, setting our brains on autopilot and relaxing into the unconscious comfort of familiar routine. “Not choice, but habit rules the unreflecting herd,” William Wordsworth said in the 19th century. In the everchanging 21st century, even the word “habit” carries a negative implication.So it seems paradoxical to talk about habits in the same context as creativity and innovation. But brain researchers have discovered that when we consciously develop new habits, we create parallel synaptic paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks.Rather than dismissing ourselves as unchangeable creatures of habit, we can instead direct our own change by consciously developing new habits. In fact, the more new things we trythe more we step outside our comfort zonethe more inherently creative we become, both in the workplace and in our personal lives.But dont bother trying to kill off old habits; once those ruts of procedure are worn into the brain, theyre there to stay. Instead, the new habits we deliberately ingrain into ourselves create parallel pathways that can bypass those old roads.“The first thing needed for innovation is a fascination with wonder,” says Dawna Markova, author of The Open Mind . “But we are taught instead to decide, just as our president calls himself the Decider. ” She adds, however, that “to decide is to kill off all possibilities but one. A good innovational thinker is always exploring the many other possibilities.”All of us work through problems in ways of which were unaware, she says. Researchers in the late 1960s discovered that humans are born with the capacity to approach challenges in four primary ways: analytically, procedurally, relationally (or collaboratively) and innovatively. At the end of adolescence, however, the brain shuts down half of that capacity, preserving only those modes of thought that have seemed most valuable during the first decade or so of life.The current emphasis on standardized testing highlights analysis and procedure, meaning that few of us inherently use our innovative and collaborative modes of thought. “This breaks the major rule in the American belief systemthat anyone can do anything,” explains M. J. Ryan, author of the 2006 book This Year I Will. and Ms. Markovas business partner. “Thats a lie that we have perpetuated, and it fosters commonness. Knowing what youre good at and doing even more of it creates excellence.” This is where developing new habits comes in.Text 2It is a wise father that knows his own child, but today a man can boost his paternal (fatherly) wisdomor at least confirm that hes the kids dad. All he needs to do is shell out $30 for a paternity testing kit (PTK) at his local drugstoreand another $120 to get the results.More than 60,000 people have purchased the PTKs since they first became available without prescriptions last years, according to Doug Fogg, chief operating officer of Identigene, which makes the overthecounter kits. More than two dozen companies sell DNA tests directly to the public, ranging in price from a few hundred dollars to more than $2500.Among the most popular : paternity and kinship testing , which adopted children can use to find their bio logical relatives and families can use to track down kids put up for adoption. DNA testing is also the latest rage among passionate genealogistsand supports businesses that offer to search for a familys geographic roots.Most tests require collecting cells by swabbing saliva in the mouth and sending it to the company for testing. All tests require a potential candidate with whom to compare DNA.But some observers are skeptical, “There is a kind of false precision being hawked by people claiming they are doing ancestry testing,” says Trey Duster, a New York University sociologist. He notes that each individual has many ancestorsnumbering in the hundreds just a few centuries back. Yet most ancestry testing only considers a single lineage, either the Y chromosome inherited through men in a fathers line or mitochondrial DNA, which is passed down only from mothers. This DNA can reveal genetic information about only one or two ancestors, even though, for example, just three generations back people also have six other greatgrandparents or, four generations back, 14 other greatgreatgrandparents.Critics also argue that commercial genetic testing is only as good as the reference collections to which a sample is compared. Databases used by some companies dont rely on data collected systematically but rather lump together information from different research projects. This means that a DNA database may have a lot of data from some regions and not others , so a persons test results may differ depending on the company that processes the results. In addition, the computer programs a company uses to estimate relationships may be patented and not subject to peer review or outside evaluation.Text 1While still catching-up to men in some spheres of modern life, women appear to be way ahead in at least one undesirable category. Women are particularly susceptible to developing depression and anxiety disorders in response to stress compared to men, according to Dr. Yehuda, chief psychiatrist at New Yorks Veterans Administration Hospital.Studies of both animals and humans have shown that sex hormones somehow affect the stress response, causing females under stress to produce more of the trigger chemicals than do males under the same conditions. In several of the studies, when stressed-out female rats had their ovaries (the female reproductive organs) removed, their chemical responses became equal to those of the males.Adding to a womans increased dose of stress chemicals, are her increased opportunities for stress. Its not necessarily that women dont cope as well. Its just that they have so much more to cope with, says Dr. Yehuda. Their capacity for tolerating stress may even be greater than mens, she observes, its just that theyre dealing with so many more things that they become worn out from it more visibly and sooner.Dr. Yehuda notes another difference between the sexes. I think that the kinds of things that women are exposed to tend to be in more of a chronic or repeated nature. Men go to war and are exposed to combat stress. Men are exposed to more acts of random physical violence. The kinds of interpersonal violence that women are exposed to tend to be in domestic situations, by, unfortunately, parents or other family members, and they tend not to be one-shot deals. The wear-and-tear that comes from these longer relationships can be quite devastating.Adeline Alvarez married at 18 and gave birth to a son, but was determined to finish college. I struggled a lot to get the college degree. I was living in so much frustration that that was my escape, to go to school, and get ahead and do better. Later, her marriage ended and she became a single mother. Its the hardest thing to take care of a teenager, have a job, pay the rent, pay the car payment, and pay the debt. I lived from paycheck to paycheck.Not everyone experiences the kinds of severe chronic stresses Alvarez describes. But most women today are coping with a lot of obligations, with few breaks, and feeling the strain. Alvarezs experience demonstrates the importance of finding ways to diffuse stress before it threatens your health and your ability to function.Text 2It used to be so straightforward. A team of researchers working together in the laboratory would submit the results of their research to a journal. A journal editor would then remove the authors names and affiliations from the paper and send it to their peers for review. Depending on the comments received, the editor would accept the paper for publication or decline it. Copyright rested with the journal publisher, and researchers seeking knowledge of the results would have to subscribe to the journal.No longer. The Internet - and pressure from funding agencies, who are questioning why commercial publishers are making money from government-funded research by restricting access to it - is maki
