Bringing science to the art of strategy.

Many managers feel doomed to trade off the futile rigor of ordinary strategic planning for the hit-or-miss creativity of the alternatives. In fact, the two can be reconciled to produce novel but realistic strategies. The key is to recognize that conventional strategic planning, for all its analysis, is not actually scientific-it lacks the careful generation and testing of hypotheses that are at the heart of the scientific method.

Intrathoracic fracture-dislocation of the humeral head: a case report.

Fracture-dislocation of the humeral head into the thoracic cavity is a rare injury. We present one such case in a 70-year-old woman. She presented with a 4-part fracture-dislocation of the proximal humerus, with displacement of the humeral head into the thoracic cavity.

How strategists really think. Tapping the power of analogy.

Leaders tend to be so immersed in the specifics of strategy that they rarely stop to think how much of their reasoning is done by analogy. As a result, they miss useful insights that psychologists and other scientists have generated about analogies' pitfalls. Managers who pay attention to their own analogical thinking will make better strategic decisions and fewer mistakes.

Syringoid eccrine carcinoma.

Eccrine carcinomas are locally aggressive and have an infiltrative growth pattern. They have a variable clinical appearance and a diversity of histologic findings that often make the diagnosis difficult. The histologic findings, together with immunoperoxidase and enzyme histochemical studies, usually allow differentiation between eccrine carcinomas, other cutaneous neoplasms, and visceral adenocarcinomas with skin metastases.
