Mobile and handheld devices are becoming an integral part of people’s work, life and entertainment. These lightweight pocket-sized devices offer great mobility, acceptable computation power and friendly user interfaces. As people are making business transactions and managing their online bank accounts via handheld devices, they are concerned with the security level that mobile devices and systems provide. In this chapter we will discuss whether these devices, equipped with very limited computation power compared to full-sized computers, can make equivalent security services available to users. We focus on the security designs and technologies of hardware, operating systems and applications for mobile and handheld devices.

Animation has become ubiquitous within digital visual culture and fundamental to knowledge production. As such, its status as potentially reliable imagery should be clarified. This article examines how animation’s indexicality (both as trace and deixis) changes in mixed realities where the physical and the virtual converge, and how this contributes to the research of animation as documentary and/or non-fiction imagery. In digital culture, animation is used widely to depict both physical and virtual events, and actions. As a result, animation is no longer an interpretive visual language. Instead, animation in virtual culture acts as real-time visualization of computer-mediated actions, their capture and documentation. Now that animation includes both captured and generated imagery, not only do its definitions change but its link to the realities depicted and the documentary value of animated representations requires rethinking. This article begins with definitions of animation and their relation to the perception of animation’s validity as documentary imagery; thereafter it examines indexicality and the strength of indexical visualizations, introducing a continuum of strong and weak indices to theorize the hybrid and complex forms of indexicality in animation, ranging from graphic user interfaces (GUI) to data visualization. The article concludes by examining four indexical connections in relation to physical and virtual reality, offering a theoretical framework with which to conceptualize animation’s indexing abilities in today’s mixed realities.

ABSTRACT In May 1996, the Department of the Interior (Interior) issued final natural resource damage assessment (NRDA) regulations enabling trustees to use new computer models in determining claims against parties responsible for spills. The new regulations incorporate a number of advances in the fields of computer technology, data management, data visualization, and graphic user interfaces. The models integrate spill simulation capability with a national coastal geographic information system (GIS) and expansive databases of chemical and petroleum characteristics, resource valuation, and restoration costs. The development and issuance of the regulations have been the focus of much attention and controversy. Interior heralds the models as “state-of-the-art” procedures, whereas other groups attack the models as “junk science.” This paper briefly examines the principal arguments both supporting and attacking the new models. It also provides the results of model application to a database of real-world historical spill events in coastal and marine environments. Finally, model output is compared to damage claims developed using other simplified procedures (i.e., compensation formulas) in the state of Washington.
