单选题Beyond the basic animal instincts to seek food and avoid pain, Freud identified two sources of psychic energy, which he called "drives": aggression and libido. The key to his theory is that these were unconscious drives, shaping our behavior without the mediation of our waking minds; they surface, heavily disguised, only in our dreams. The work of the past half-century in psychology and neuroscience has been to downplay the role of unconscious universal drives, focusing instead on rational processes in conscious life. But researchers have found evidence that Freud's drives really do exist, and they have their roots in the limbic system, a primitive part of the brain that operates mostly below the horizon of consciousness. Now more commonly referred to as emotions, the modern suite of drives comprises five: rage, panic, separation distress, lust and a variation on libido sometimes called seeking. The seeking drive is proving a particularly fruitful subject for researchers. Although like the others it originates in the limbic system, it also involves parts of the forebrain, the seat of higher mental functions. In the 1980s, Jaak Panksepp, a neurobiologist at Bowling Green State University in Ohio, became interested in a place near the cortex known as the ventral tegmental area, which in humans lies just above the hairline. When Panksepp stimulated the corresponding region in a mouse, the animal would sniff the air and walk around, as though it were looking for something. Was it hungry? No. The mouse would walk right by a plate of food, or for that matter any other object Panksepp could think of. This brain tissue seemed to cause a general desire for something new. "What I was seeing, " he says, "was the urge to do stuff. " Panksepp called this seeking. To neuropsychologist Mark Solms of University College in London, that sounds very much like libido. "Freud needed some sort of general, appetitive desire to seek pleasure in the world of objects, " says Solms. "Panksepp discovered as a neuroscientist what Freud discovered psychologically. " Solms studied the same region of the brain for his work on dreams. Since the 1970s, neurologists have known that dreaming takes place during a particular form of sleep known as REM — rapid eye movement — which is associated with a primitive part of the brain known as the pons. Accordingly, they regarded dreaming as a low-level phenomenon of no great psychological interest. When Solms looked into it, though, it turned out that the key structure involved in dreaming was actually the ventral tegmental, the same structure that Panksepp had identified as the seat of the "seeking" emotion. Dreams, it seemed, originate with the libido—which is just what Freud had believed. Freud's psychological map may have been flawed in many ways, but it also happens to be the most coherent and, from the standpoint of individual experience, meaningful theory of the mind. "Freud should be placed in the same category as Darwin, who lived before the discovery of genes, " says Panksepp. "Freud gave us a vision of a mental apparatus. We need to talk about it, develop it, test it. " Perhaps it's not a matter of proving Freud wrong or right, but of finishing the job.

单选题Companies have embarked on what looks like the beginnings of a re-run of the mergers and acquisitions (M&A) wave that defined the second bubbly half of the 1990s. That period, readers might recall, was characterized by a collective splurge that saw the creation of some of the most indebted companies in history, many of which later went bankrupt or were themselves broken up. Wild bidding for telecoms, internet and media assets, not to mention the madness that was Daimler"s $40 billion motoring takeover in 1998-1999 of Chrysler or the Time- Warner/AOL mega-merger in 2000, helped to give mergers a thoroughly bad name. A consensus emerged that M&A was a great way for investment banks to reap rich fees, and a sure way for ambitious managers to betray investors by trashing the value of their shares. Now M&A is back. Its return is a global phenomenon, but it is perhaps most striking in Europe, where so far this year there has been a stream of deals worth more than $600 billion in total, around 40% higher than in the same period of 2004. The latest effort came this week when France"s Saint-Gobain, a building-materials firm, unveiled the details of its ￡3.6 billion ($6.5 billion) hostile bid for BPB, a British rival. In the first half of the year, cross-border activity was up threefold over the same period last year. Even France Telecom, which was left almost bankrupt at the end of the last merger wave, recently bought Amena, a Spanish mobile operator. Shareholder"s approval of all these deals raises an interesting question for companies everywhere: are investors right to think that these mergers are more likely to succeed than earlier ones? There are two answers. The first is that past mergers may have been judged too harshly. The second is that the present rash of European deals does look more rational, but—and the caveat is crucial—only so far. The pattern may not hold. M&A"s poor reputation stems not only from the string of spectacular failures in the 1990s, but also from studies that showed value destruction for acquiring shareholders in 80% of deals. But more recent studies by economists have introduced a note of caution. Investors should look at the number of deals that succeed or fail (typically measured by the impact on the share price), rather than (as you might think) weighing them by size. For example, no one doubts that the Daimler-Chrysler merger destroyed value. The combined market value of the two firms is still below that of Daimler alone before the deal. This single deal accounted for half of all German M&A activity by value in 1998 and 1999, and probably dominated people"s thinking about mergers to the same degree. Throw in a few other such monsters and it is no wonder that broad studies have tended to find that mergers are a bad idea. The true picture is more complicated.
