| We introduce the concept of cognitive design patterns and discuss ways in which these patterns can better integrate early work analyses with software development. Cognitive design patterns are units of work that, in combination, enable human operators to accomplish the range of tasks needed for success in complex systems. Each pattern consists of a normative model of the relevant cognitive competency, expressed in terms accessible to software design and practice. ... |

 | Modeling languages such as UML and IDEF1-X provide only partial coverage for the relations and constraints that apply to information within a given domain of interest. In most cases additional textual narratives are required to capture the full set of pertinent business rules. The Semantics of Business Vocabulary and Business Rules Specification (SBVR), an OMG adopted specification, offers an alternative to traditional information modeling with vastly more powerful capabilities and ... |

|
| Do you know what the impact of your Service Oriented Architecture (SOA) deployment is to the operational network? During deployment, the network requirements for the application are discovered. Deploying functions directly to the operational network forces the network technicians to quickly adapt the network to these requirements. Since this is not optimal, we need an improved process. A way of improving this process is to use a test network that ... |

| Having decided to focus attention on the "weak link" of human fallibility, a growing number of security researchers are discovering the US Government's regulations that govern human subject research. This paper discusses those regulations, their application to research on security and usability, and presents strategies for negotiating the Institutional Review Board (IRB) approval process. It argues that a strict interpretation of regulations has the potential to stymie security research. |
