BACKGROUND Gastric cancer is a major cause of cancer death, and many patients are only diagnosed when the cancer has reached an advanced stage. Neoadjuvant chemotherapy (NAC), that is, chemotherapy administered shortly before surgical treatment, could provide a method of increasing the possibility of complete resection and survival. OBJECTIVES To evaluate the effect of neoadjuvant chemotherap...

THE PURSUIT OF EVIDENCE-BASED MEDICINE IS NOW AT the core of the agenda for improving health care in the United States. All major quality measurement systems use science-based indicators of proper processes of care, such as the ORYX measures of the Joint Commission on Accreditation of Healthcare Organizations, the Health Employer Data and Information Sets measures of the National Committee on Q...

The keratocystic odontogenic tumor is a benign developmental tumor with many distinguishing clinical and histologic features. These characteristics are reviewed in the setting of a typical presentation. The newly acknowledged neoplastic potential and its implications for treatment strategies are also discussed.

In the history of SLA research, the relationship between explicit and implicit knowledge has incited heated debate, culminating in, broadly, three disparate positions: (a) the non-interface; (b) the weak-interface; and (c) the stronginterface. In this paper, we re-engage the theoretical debate. Unlike the previous discussions, however, which typically find researchers espousing one position aga...

120 words) A tidal wave of recent research purports to have discovered that higher-level states such as moods, action-capabilities, and categorical knowledge can literally and directly affect what we see. Are these truly effects on perception, or might some instead reflect influences on judgment, memory, or response bias? Here, we exploit an infamous art-historical reasoning error (the socalled...

It is difficult to estimate the probability of a word's context because of sparse data problems. If appropriate care is taken, we find that it is possible to make useful estimates of contextual probabilities that improve performance in a spelling correction application. In contrast, less careful estimates are found to be useless. Specifically, we will show that the Good-Turing method makes the ...

This paper reports a study designed to investigate whether the all-or-none conception of the learning process can be extended to a learning task more complex than conditioning or simple verbal association. The experimental task is to learn numerical sequences by anticipating each new member of the sequences. Although the obtained sequence learning appears very complex, it proves to be analyzabl...

Coordinating activity among members is an important problem faced by organizations. When firms, or units within firms, are stuck in bad equilibria, managers may turn to the temporary use of simple incentives—flat punishments or rewards—in an attempt to transition the firm or unit to a more efficient equilibrium. We investigate the use of incentives in the context of the “minimum-effort,” or “we...
