Human beings, born with a drive to explore and experiment, thrive on learning. Unfortunately, corporations are oriented predominantly toward controlling employees, not fostering their learning. Ironically, this orientation creates the very conditions that predestine employees to mediocre performances. Over time, superior performance requires superior learning, because long-term corporate survival depends on continually exploring new business and organizational opportunities that can create new sources of growth. To survive in the future, corporations must become "learning organizations," enterprises that are constantly able to adapt and expand their capabilities. To accomplish this, corporations must change how they view employees. The traditional view that a single charismatic leader should set the corporation's direction and make key decisions is rooted in an individualistic worldview. In an increasingly interdependent world, such a view is no longer viable. In learning organizations, thinking and acting are integrated at all job levels. Corporate leadership is shared, and leaders become designers, teachers, and stewards, roles requiring new skills: the ability to build shared vision, to reveal and challenge prevailing mental models, and to foster broader, more integrated patterns of thinking. In short, leaders in learning organizations are responsible for building organizations in which employees are continually learning new skills and expanding their capabilities to shape their future.

Structural unemployment-the unemployment that remains even at the peak of the economy's upswings-is caused by an imbalance between the types and locations of available employment on the one hand and the qualifications and locations of workers on the other hand. When such an imbalance exists, both labor shortages and unemployment may occur, despite a balance between supply and demand for labor in the economy as a whole.Because technological change is likely to displace some workers, it is a major factor in producing structural unemployment. While technological . advance almost invariably results in shifts in demands for different types of workers, it does not necessarily result in unemployment. Relatively small or gradual changes in demand are likely to cause little unemployment. In the individual firm or even in the labor market as a whole, normal attrition may be sufficient to reduce the size of the work force in the affected occupations. Relatively large or rapid changes, however, can cause serious problems. Workers may lose their jobs and find themselves without the skills necessary to obtain new jobs. Whether this displacement leads to structural unemployment depends on the amount of public and private sector resources devoted to retraining and placing those workers. Workers can be encouraged to move where there are jobs, to reeducate or retrain themselves, or to retire. In addition, other factors affecting structural unemployment, such as capital movement, can be controlled. Increased structural unemployment, should it occur, makes it difficult for the economy to achieve desired low rates of unemployment along with low rates of inflation. If there is a growing pool of workers who lack the necessary skills for the available jobs, ·increases in total labor demand will rapidly generate shortages of qualified workers. As the wages of those workers are bid up, labor costs, and thus prices, rise. This phenomenon may be an important factor in the rising trend, observed for the past two decades, of unemployment combined with inflation. Government policy has placed a priority on reducing inflation, but these efforts have nevertheless caused unemployment to increase.

A key decision required of advertising managers is whether a "hard-sell" or "soft-sell" strategy is appropriate for a specific target market. The hardsell approach involves the use of direct, forceful claims regarding the benefits of the advertised brand over competitors' offerings. In contrast, the soft-sell approach involves the use of advertising claims that imply superiority more subtly. One positive aspect of the hard-sell approach is its use of very simple and straightforward product claims presented as explicit conclusions, with little room for confusion regarding the advertiser's message. However, some consumers may resent being told what to believe and some may distrust the message. Resentment and distrust often lead to counterargumentation and to boomerang effects where consumers come to believe conclusions diametrically opposed to conclusions endorsed in advertising claims. By contrast, the risk of boomerang effects is greatly reduced with soft-sell approaches. One way to implement the soft-sell approach is to provide information that implies the main conclusions the advertiser wants the consumer to draw, but leave the conclusions themselves unstated. [line:25]Because consumers are invited to make up their own minds, implicit conclusions reduce the risk of resentment, distrust, and counterargumentation.[/line:25] Recent [hl:7]research[/hl:7] on consumer memory and judgment suggests another advantage of implicit conclusions. Beliefs or conclusions that are selfgenerated are more accessible from memory than beliefs from conclusions provided explicitly by other individuals, and thus have a greater impact on judgment and decision making. Moreover, selfgenerated beliefs are often perceived ·as more accurate and valid than the beliefs of others, because other individuals may be perceived as less knowledgeable, or may be perceived as manipulative or deliberately misleading. Line Despite these advantages, implicit conclusions may not always be more effective than explicit conclusions. One risk is that some consumers may fail to draw their own conclusions and thus miss the point of the message. Inferential activity is likely only when consumers are motivated and able to engage in effortful cognitive processes. Another risk is that some consumers may draw conclusions other than the one intended. Even if inferential activity is likely there is no guarantee that consumers will follow the path provided by the advertiser. Finally, a third risk is that consumers may infer the intended conclusion but question the validity of their inference.

Newsletter: A condominium generally offers more value for its cost than an individual house because of economies of scale.
The homeowners in a condominium association can collectively buy products and services that they could not afford on their own. And since a professional management company handles maintenance of common areas, condominium owners spend less time and money on maintenance than individual homeowners do.
The two portions in boldface play which of the following roles in the newsletter's argument?

In Australia, in years with below-average rainfall, less water goes into rivers and more water is extracted from rivers for drinking and irrigation. Consequently, in such years, water levels drop considerably and the rivers flow more slowly. Because algae grow better the more slowly the water in which they are growing moves, such years are generally beneficial to populations of algae. But, by contrast, populations of algae drop in periods of extreme drought.
Which of the following, if true, does most to explain the contrast?

Pro-Teet Insurance Company has recently been paying out more on car-theft claims than it expected. Cars with special antitheft devices or alarm systems are much less likely to be stolen than are other cars. Consequently Pro-Teet, as part of an effort to reduce its annual payouts, will offer a discount to holders of car-theft policies if their cars have antitheft devices or alarm systems.
Which of the following, if true, provides the strongest indication that the plan is likely to achieve its goal?

Findings from several studies on corporate mergers
and acquisitions during the 1970's and 1980's raise
questions about why firms initiate and consummate
such transactions. One study showed, for example,
that acquiring firms were on average unable to
maintain acquired firms' pre-merger levels of
profitability. A second study concluded that post-
acquisition gains to most acquiring firms were not
adequate to cover the premiums paid to obtain
acquired firms. A third demonstrated that, following
the announcement of a prospective merger, the
stock of the prospective acquiring firm tends to
increase in value much less than does that of the
firm for which it bids. Yet mergers and acquisitions
remain common, and bidders continue to assert
that their objectives are economic ones.
Acquisitions may well have the desirable effect of
channeling a nation's resources efficiently from less
to more efficient sectors of its economy, but the
individual acquisitions executives arranging these
deals must see them as advancing either their own
or their companies' private economic interests. It
seems that factors having little to do with corporate
economic interests explain acquisitions. These
factors may include the incentive compensation of
executives, lack of monitoring by boards of
directors, and managerial error in estimating the
value of firms targeted for acquisition. Alternatively,
the acquisition acts of bidders may derive from
modeling: a manager does what other managers do.

A newly discovered painting seems to be the work of one of two 17th-century artists, either the northern German Johannes Drechen or the Frenchman Louis Birelle, who sometimes painted in the same style as Drechen. Analysis of the carved picture frame, which has been identified as the painting's original 17thcentury frame, showed that it is made of wood found widely in northern Germany at the time, but rare in the part of France where Birelle lived. This shows that the painting is most likely the work of Drechen.

Curator: If our museum lends Venus to the Hart Institute for their show this spring, they will lend us their Rembrandt etchings for our print exhibition next fall. Having those etchings will increase attendance to the exhibition and hence increase revenue from our general admission fee.
Museum Administrator: But Venus is our biggest attraction. Moreover the Hart's show will run for twice as long as our exhibition. So on balance the number of patrons may decrease.
