Traditional models have divided the increasingly popular domain of leadership into contrasting, either/or categories. The vast majority of examples from the leadership literature create dichotomies of leadership (e.g., Theory X vs. Theory Y; task vs. socioemotional; participative vs. autocratic; transactional vs. transformational). There has been little effort to combine the existing dichotomie...

Medical practice is inherently ambiguous and uncertain. The physicians' ability to tolerate ambiguity and uncertainty has been proved to have a great impact on clinical practice. The primary aim of the present study was to test the hypothesis that higher degree of physicians' ambiguity and uncertainty intolerance and higher need for cognitive closure will predict higher work stress. Two hundred...

The GenBank database contains essentially all of the nucleotide sequence data generated for published molecular systematic studies, but for the majority of taxa these data remain sparse. GenBank has value for phylogenetic methods that leverage data-mining and rapidly improving computational methods, but the limits imposed by the sparse structure of the data are not well understood. Here we pres...

We introduce some new voting rules based on a spatial version of the median in R known as the mediancentre, or Fermat-Weber point. Voting rules based on the mean include many that are familiar: the Borda Count, Kemeny rule, approval voting, etc. (see [35], [36]). These mean rules can be implemented by “voting machines” (interactive simulations of physical mechanisms) that use ideal rubber bands...

OBJECTIVE Asking for help in the operating room occurs within a surgical culture that has traditionally valued independence, decisiveness, and confidence. A tension exists between these deeply ingrained character traits and the new culture of team-based practice that emphasizes maximizing patient safety. The objective of this study is to explore surgeon-to-surgeon help-seeking behaviors during ...

The concept of distance rationalizability of voting rules has been explored in recent years by several authors. Most previous work has dealt with a definition in terms of preference profiles. However, most voting rules in common use are anonymous and homogeneous. In this case there is a much more succinct representation (using the voting simplex) of the inputs to the rule. This representation h...
