Taschenbuch. Condizione: Neu. Neuware -User engagement refers to the quality of the user experience that emphasizes the positive aspects of interacting with an online application and, in particular, the desire to use that application longer and repeatedly. User engagement is a key concept in the design of online applications (whether for desktop, tablet or mobile), motivated by the observation that successful applications are not just used, but are engaged with. Users invest time, attention, and emotion in their use of technology, and seek to satisfy pragmatic and hedonic needs. Measurement is critical for evaluating whether online applications are able to successfully engage users, and may inform the design of and use of applications. User engagement is a multifaceted, complex phenomenon; this gives rise to a number of potential measurement approaches. Common ways to evaluate user engagement include using self-report measures, e.g., questionnaires; observational methods, e.g. facial expression analysis, speech analysis; neuro-physiological signal processing methods, e.g., respiratory and cardiovascular accelerations and decelerations, muscle spasms; and web analytics, e.g., number of site visits, click depth. These methods represent various trade-offs in terms of the setting (laboratory versus ``in the wild''), object of measurement (user behaviour, affect or cognition) and scale of data collected. For instance, small-scale user studies are deep and rich, but limited in terms of generalizability, whereas large-scale web analytic studies are powerful but negate users' motivation and context. The focus of this book is how user engagement is currently being measured and various considerations for its measurement. Our goal is to leave readers with an appreciation of the various ways in which to measure user engagement, and their associated strengths and weaknesses. We emphasize the multifaceted nature of user engagement and the unique contextual constraints that come to bear upon attempts to measure engagement in different settings, and across different user groups and web domains. At the same time, this book advocates for the development of ``good'' measures and good measurement practices that will advance the study of user engagement and improve our understanding of this construct, which has become so vital in our wired world. 136 pp. Englisch.…

Taschenbuch. Condizione: Neu. Neuware -This monograph grew out of the authors' efforts to provide a natural geometric description for the class of maps invariant under parabolic renormalization and for the Inou-Shishikura fixed point itself as well as to carry out a computer-assisted study of the parabolic renormalization operator. It introduces a renormalization-invariant class of analytic maps with a maximal domain of analyticity and rigid covering properties and presents a numerical scheme for computing parabolic renormalization of a germ, which is used to compute the Inou-Shishikura renormalization fixed point.Inside, readers will find a detailed introduction into the theory of parabolic bifurcation, Fatou coordinates, Écalle-Voronin conjugacy invariants of parabolic germs, and the definition and basic properties of parabolic renormalization.The systematic view of parabolic renormalization developed in the book and the numerical approach to its study will be interesting to both expertsin the field as well as graduate students wishing to explore one of the frontiers of modern complex dynamics.…

Taschenbuch. Condizione: Neu. Neuware - The NATO Advanced Study Institute held in the Hotel Metropole Llandrindod Wells, Powys, Wales from July 26th to August 4th 1981 provided an excellent platform for presentation and appraisal of our current knowledge of neurotransmitter systems. The proceed ings comprise the present volume and these were arranged to allow study of the pathways and the interactions of specific transmitter systems, one with another, in the various sub-regions of the central nervous system. In addition several of the key factors involved in neurotransmitter release were highlighted. These include the structural and molecular organisation of the nerve terminal, its organelles (such as vesicles, neurotubules and synaptic densities) and the mechanisms involved in neurotransmitter release including the participation of calcium. The organisation of transmitter synthesis, storage and transport were discussed together with their linkage to other streams of metabolism, and the cellular compartmentation of these processes. In addition to the principal lectures given at the Institute, many part1c1pants presented short reports for discussion and these are all included in this volume. The success of the Study Institute was due to the careful planning of the scientific programme to allow a smooth flow and integration of the topics included and this is reflected in the organisation of this book. The programme committee members were, R. Balazs (London), H. F. Bradford (London,Director), J. B. Clark (London), J. E. Cremer (MRC, Carshalton), J. S. Kelly (London), L. Lim (London), M. J. Neal (London) and P. J. Roberts (Southampton).…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As cities develop, more land is converted into impervious surfaces, which do not allow water to infiltrate. Careful urban planning is needed to ensure that the hydrologic cycle and water quality of the catchment areas are not affected. There are techniques that can attenuate peak flow during rain events and reduce the amount of metals, nutrients, and bacteria that enter the urban water cycle. This brief gives a short introduction on bioretention systems and documents the effectiveness of some 36 plant species in removing water pollutants. A summary on the maintenance requirements is also presented. 68 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This compact, forcefully argued work calls Sam Harris, Richard Dawkins, Steven Pinker, and the rest of the so-called 'New Atheists' to account for failing to take seriously the historical record to which they so freely appeal when attacking religion. The popularity of such books as Harris's The End of Faith, Dawkins's The God Delusion, and Christopher Hitchens' God Is Not Great set off a spate of reviews, articles, and books for and against, yet in all the controversy little attention has focused on the historical evidence and arguments they present to buttress their case. This book is the first to challenge in depth the distortions of this New Atheist history. It presents the evidence that the three authors and their allies ignore. It points out the lack of historical credibility in their work when judged by the conventional criteria used by mainstream historians. It does not deal with the debate over theism and atheism nor does it aim to defend the historical record of Christianity or religion more generally. It does aim to defend the integrity of history as a discipline in the face of its distortion by those who violate it. 194 pp. Englisch.…
