Computers, Commmunication, and Mental Models is a far-ranging, focused treatment of the cognitive and behavioural issues in computer-mediated communication, knowledge representation and computer-supported co- operative work. It is also an argued development of the theoretical bases for treating computerized tools as intermediaries in the communication of mental maps between tool builders and users. Empirical trails are reported in detail sufficient for representation, in computer-based instruction, fractal dimensions of cognitive mapping and group decision support. The book is a collection of multidisciplinary papers which each shed light on the complex interactions between users and systems architects, via a common medium: computerized tools.

Offering comprehensive coverage of this hot topic, this two-volume handbook and ready reference treats a wide range of important aspects, from synthesis and catalytic properties of carbon materials to their applications as metal-free catalysts in various important reactions and industrial processes. Following a look at recent advances in the development of carbon materials as carbon-based metal-free catalysts, subsequent sections deal with a mechanistic understanding for the molecular design of efficient carbon-based metal-free catalysts, with a special emphasis on heteroatom-doped carbon nanotubes, graphene, and graphite. Examples of important catalytic processes covered include clean energy conversion and storage, environmental protection, and synthetic chemistry. With contributions from world-leading scientists, this is an indispensable source of information for academic and industrial researchers in catalysis, green chemistry, electrochemistry, materials science, nanotechnology, energy technology, and chemical engineering, as well as graduates and scientists entering the field.

From the moment we wake up to the moment we end our day, we use interfaces built out of the written word. Textual information remains now, as it has for centuries, the cornerstone of human information acquisition. The wide adoption of smartphone, tablets, e-readers and personal computers has shifted the bulk of this reading from inflexible paper to digital content. The control provided by digital displays over how visual information is presented to readers has the potential to improve reading for each and every reader, regardless of ability or diagnosis. This represents a profound shift in how we think about reading because text is no longer rendered immutable by writers, designers, or publishers at a single stage, and human-computer interaction research is key to realizing its potential. Readability research takes a fundamentally individual approach to what each reader needs. Each reader has their own individual needs. Meanwhile, adapting the written word to the individual reader has never been easier, and the goal of maximizing individual reading efficacy is increasingly attainable. No one discipline or field has all the tools or answers, and readability work is inherently interdisciplinary. The authors of this monograph include vision scientists, technology experts, educators, designers, typographers, and data scientists. Together they represent voices from academia, the tech industry, and non-profit institutions, driven by common goals to improve the reading interfaces of today. In this review, they provide a comprehensive introduction to interdisciplinary methodologies, tools, and materials required for readability research focused on the individual reader. They call on the HCI community to contribute to the growing understanding of readers’ needs; to study the interactions between text, user, and task; and to build the tools and interfaces needed to improve reading outcomes for all.

Balance, Gait, and Falls, Volume 159 presents the latest information on sensorimotor anatomy, sensory integration, gravity and verticality, standing balance, balance perturbations, voluntary stepping and gait initiation, gait and gait adaptability, disorders of balance and gait that result from aging and neurological diseases. The book provides a brief overview of age-related changes in the structure and function of sensorimotor and central processes, with sections specifically devoted to Parkinson's disease, parkinsonism, cerebellar ataxia, stroke, corticobasal degeneration, multiple sclerosis, Huntington's disease, dystonia, tremor, Alzheimer's disease, frontotemporal dementia, cerebral palsy, polio, motor neuron disease, brainstem lesions, spinal lesions, peripheral nerve disease, and psychogenic conditions. Diseases covered have a common structure comprising background and epidemiology, pathology, balance disorders, gait disorders, falls, therapies (including fall prevention), and future directions.
