  • With globalisation and knowledge-based production, firms may cooperate on a global scale, outsource parts of their administrative or productive units and negate location altogether. The extremely low transaction costs of data, information and knowledge seem to invalidate the theory of agglomeration and the spatial clustering of firms, going back to the classical work by Alfred Weber (1868-1958) and Alfred Marshall (1842-1924), who emphasized the microeconomic benefits of industrial collocation.

  • Lichen Planus Lichen planus (LP) is a papulosquamous disorder that may affect the skin, scalp, nails, and mucous membranes. The primary cutaneous lesions are pruritic, polygonal, flat-topped, violaceous papules. Close examination of the surface of these papules often reveals a network of gray lines (Wickham's striae). The skin lesions may occur anywhere but have a predilection for the wrists, shins, lower back, and genitalia (Fig. 53-5).

  • Product counterfeiting is a well-known problem, one that has been with us for a very long time. Trademarks go back to ancient times and where there are trade- marks counterfeiting soon follows. Recently more attention is being paid to fighting the problem. It would seem the first logical step would be to determine the size of the counterfeit market. But this is more difficult than it appears to be. First, no direct measurement of counterfeit trade can be undertaken, since by definition this is an illegal activity.

  • Moe Gibson stood alone, facing his locker, bawling like a baby. He had already removed his shoulder pads and the navy blue jersey emblazoned on both sides with No. 22, the one with his surname printed in large capital letters on the reverse and “Villanova,” in smaller type, along the front. Gibson, by now the only person remaining in the university’s spacious football locker room, cried for the name on the back of the jersey, and he cried for the name on the front.

  • The NASA Mars Sojourner rover inspired this project . I followed the mission with great enthusiasm and witnessed a giant leap in robotics that day it began roaming the Martian terrain and sending images back to earth. Though I was in awe when the Viking missions of the 1970’s were in progress, we didn’t see that near real-time interaction with the craft .

  • The gesture has two versions; the raised steeple (Figure 42), the position normally taken when the steepler is giving his opinions or ideas and is doing the talking. The lowered steeple gesture (Figure 43) is normally used when the steepler is listening rather than speaking. Nierenberg and Calero noted that women tend to use the lowered steeple position more often than the raised steeple position. When the raised steeple position is taken with the head tilted back, the person assumes an air of smugness or arrogance. Although the steeple gesture is a positive signal, it can be used in...

  • Sensitization When intense, repeated, or prolonged stimuli are applied to damaged or inflamed tissues, the threshold for activating primary afferent nociceptors is lowered and the frequency of firing is higher for all stimulus intensities. Inflammatory mediators such as bradykinin, nerve growth factor, some prostaglandins, and leukotrienes contribute to this process, which is called sensitization. In sensitized tissues, normally innocuous stimuli can produce pain. Sensitization is a clinically important process that contributes to tenderness, soreness, and hyperalgesia.

  • Making a good walkcycle requires more than just arm and foot positioning. Spend some time on the spine. When walking, the leading hand twists the top of the spine toward it, and the trailing arm twists the lower spine toward it. Be aware, though, that by rotating the lower spine bones, the upper spine, arms, neck, and head will rotate as well. You may have to compensate by rotating the upper spine bones back the opposite way. Rotations of the spine during a walkcycle should be subtle: they add hints to the overall motion. Over-rotating will produce animation that looks wild and unnatural....

In Japan the out performance has been greater than 300 basis points a year. In emerging markets, the technique has shown even greater excess returns over capitalization- weighted indexes.

  • Worse, because the consumer fails to see that she will pay a large penalty and back-load repayment—and not because she has a taste for immediate gratification with respect to consumption— she underestimates the cost of credit and borrows too much. Due to this combination of decisions, a nonsophisticated consumer, no matter how close to sophisticated, has discontinuously lower welfare than a sophisticated consumer.
