Guided by the risk information-seeking and processing model, this study examines positive and negative affect separately in their influence on information-seeking intentions and avoidance through structural equation analyses. The highlight is that information avoidance seems to be driven by positive affect, while information seeking seems to be more heavily influenced by negative affect. Another interesting finding is that informational subjective norms are positively related to both seeking and avoidance, which suggests that one’s social environment has the potential to strongly influence the way he or she handles climate change information. Implications for theory and practice are discussed.

People have difficulties using computers. Some have more difficulties than others. There is a need for guidance in how to evaluate and improve the accessibility of systems for users. Since different users have considerably different accessibility needs, accessibility is a very complex issue.
ISO 9241-171 defines accessibility as the "usability of a product, service, environment or facility by people with the widest range of capabilities." While this definition can help manufacturers make their products more accessible to more people, it does not ensure that a given product is accessible to a particular individual.
A reference model is presented to act as a theoretical foundation. This Universal Access Reference Model (UARM) focuses on the accessibility of the interaction between users and systems, and provides a mechanism to share knowledge and abilities between users and systems. The UARM also suggests the role assistive technologies (ATs) can play in this interaction. The Common Accessibility Profile (CAP), which is based on the UARM, can be used to describe accessibility.
The CAP is a framework for identifying the accessibility issues of individual users with particular systems configurations. It profiles the capabilities of systems and users to communicate. The CAP can also profile environmental interference to this communication and the use of ATs to transform communication abilities. The CAP model can be extended as further general or domain specific requirements are standardized.
The CAP provides a model that can be used to structure various specifications in a manner that, in the future, will allow computational combination and comparison of profiles.
Recognizing its potential impact, the CAP is now being standardized by the User Interface subcommittee the International Organization for Standardization and the International Electrotechnical Commission.

An interactive provides varying levels of interactivity, ranging from simple point-and-click interaction through sophisticated search techniques to the analysis, manipulation, and application of information in new and authentic contexts.
The Madingley Model simulates how the structure and function of ecosystems at global scales emerges from the underlying ecology of individual organisms.
The InfluSim Project
Making Pandemic Influenza Modelling Tools Available to the Public
With the emergence of the Mexican flu we have decided to make all our pandemic influenza modelling and simulation tools available on the web. We encourage health care policy makers to use this software. And we would appreciate if other mathematical modellers made their pandemic influenza software public, too.

23--29(1999)ST: Vorgehensweise: Das Paper ordnet den Vorgang, wie man sicherheitskritische Anforderungen verifizieren kann, in einen Software Life-Cycle ein. Use-Cases werden mit Parametern für Daten versehen. Die Eingabedaten werden mit Hilfe eines Tools generiert per üblicher Ä-Klassenanalyse.
Eignung: Es ist nichts über die Testgüte zu finden (Abdeckungskriterium etc.). Außerdem wird kein Testmodell o.ä. erwähnt, welches alternative Ausführungspfade des Use Cases repräsentiert..
