Abstract
Decision system analysis is a conceptually simple technique that maps the process of group decisions over time. The data is gathered in a variety of ways, but most often some form of protocol analysis is the foremost tool. The data is then condensed and depicted as a flowchart for a specific decision. If several such flowcharts can be assembled within an industry, they can be melded together to form a generic guide that is very useful to practitioners and very interesting to theorists. Here, a brief history of the development of the technique leads to a description of the process. This is followed by a comparison to cognitive mapping (a similar technique applied to mapping thought processes rather than physical processes), and an illustrative longitudinal example of DSA.

Abstract
Purpose – In an attempt to enhance patient safety, health care facilities are increasingly turning to crew resource management (CRM) and other teamwork training interventions. However, there is still quite a bit about such training interventions that remain unclear. Accordingly, our primary intent herein is to provide some clarity by providing a review of the literature, in hopes of highlighting the current state of the literature as well as identifying the areas that should be addressed by researchers in this field going forward.
Design/methodology/approach – We searched various electronic databases and utilized numerous relevant search terms to maximize the likelihood of identifying all empirical research related to the use of CRM training within health care. Additionally, we conducted a manual search of the most relevant journals and also conducted a legacy search to identify even more articles. Furthermore, given that as a research team we have experience with CRM initiatives, we also integrate the lessons learned through this experience.
Findings – Based on our review of the literature, CRM and teamwork training programs generally appear beneficial to individual employees, the groups and teams within such settings, and overall health care organizations.
Originality/value – In addition to reviewing the literature that addressed CRM and teamwork training, we also highlight some of the more critical aspects of CRM training programs in order for such initiatives to be as successful as possible. Additionally, we detail various factors that appear essential to sustaining any benefits of CRM over the long haul.

Abstract
The economic doctrine of market efficiency plays an essential role in securities fraud litigation. In lawsuits alleging violations of SEC Rule 10b-5, the plaintiffs typically must argue that the market for the relevant security is efficient, and therefore that the “fraud on the market” doctrine applies. However, the term “market efficiency” is often applied imprecisely. In this chapter, we discuss properties of efficient markets that have been proposed in academic research, legal scholarship, and case law. We explore what must be assumed about capital markets for each of these properties to hold. We then ask how, in practice, each property could be rebutted.
